3. Product description

3.1 Key features

BYOD

Kindermann Klick&Show Systems are BYOD wireless presentation systems, for universal use in meeting rooms, huddle spaces and classrooms. Klick&Show provides users with a wide range of features to present audiovisual content from laptops or mobile devices in a really simple way – without cables, without hassle and without wasting time. Bring-your-own-device (BYOD) refers to the ability to use various mobile devices such as laptops, smartphones and tablets for presentations. In a broader definition of BYOD, this includes not only the devices provided by the company or school for everyday work and training, but also devices used privately.

BYOM

Klick&Show Devices of the K-FX series also extend the BYOD functionality with bring-your-own-meeting (BYOM). BYOM enables the wireless connection of one's own laptop to existing USB devices in the room (e.g. USB cameras, video soundbars or speakerphones) for conducting online meetings (conferencing) with one's own account of the preferred UCC platform (e.g. Microsoft Teams, Zoom, Cisco WebEx, Google Meet, etc.).
Here, the existing USB devices are first physically connected to the base device of the Klick&Show K-FX series and can then be used wirelessly on your own laptop for UC conferencing thanks to USB-over-WiFi as if they were directly connected.
Transform with BYOM Klick&Show K-FX Series transforms traditional meeting rooms into hybrid conference rooms, facilitating collaboration between the office and remote participants.

Klick&Show Transmitter

There are various transmission paths to choose from for wireless transmission of content, first and foremost the Klick&Show Transmitter, optionally for transmission in 4K resolution or Full HD, each with HDMI or USB-C interface, which allows the use of Klick&Show make it particularly easy. All transmitter types allow you to share the PC screen without installing any software. If online meetings are desired beyond pure presentation, devices of the K-FX series require the installation of device drivers and a connection to the company network. Klick&Show Transmitters are compatible with the basic units of the K-FX and K-40 series.

Klick&Show App

The Klick&Show App (software client) enables software-based sharing of a PC screen without a transmitter for all device types of the K-FX, K-40 and K-WM device series and is available for Windows and MacOS operating systems. The software client is also required to use the conferencing function on devices of the Klick&Show K-FX series and provides the wireless data stream back transmission of the UC devices connected to the base to the host laptop for UC conferences.

Generic Protocols

In addition, the generic protocols AirPlay Miracast (both protocols, peer-to-peer and MS MICE) and Google Cast (ChromeCast) are supported for image transmission. These are available directly on the respective operating system platforms without the installation of additional software and are therefore particularly easy and intuitive to use.

For mirroring Android device content, the WirelessMedia2 app is available free of charge from the Google Play Store .

All Klick&Show Device types allows the simultaneous display of up to four device contents on a main display in a (configurable) split-screen display.

For more detailed information on the features of all Klick&Show Products please follow the links in Chapter 14 Technical Data.

3.3 Compatibility with third-party USB devices

Klick&Show Thanks to the integrated BYOM functionality, K-FX and K-FX Plus enable the wireless connection of your own laptop to existing USB devices in the room (e.g. USB cameras, video soundbars or speakerphones) for conducting online meetings (conferencing) with your own account of the preferred UCC platform (e.g. Microsoft Teams, Zoom, Cisco WebEx, Google Meet, etc.).

To use BYOM, Klick&Show Devices of the K-FX series compatible with the majority of USB cameras, USB video soundbars, USB speakerphones and professional AEC (Active Echo Cancelation) solutions with USB interface available on the market. To do this, third-party USB devices must meet certain requirements.

Requirements for USB devices:

USB-A or USB-C connection
(Note: K-FX Plus supports USB-A connection for Camera 2)
USB2.0 or USB3.0 protocol/data rate
(Note: K-FX Plus supports USB 2.0 data rate for Camera 2)
Compatible to output video streams at Full HD @ 30Hz and below
Many webcams support the output of various resolution formats or refresh rates via USB. For example, cameras with an integrated 4K sensor do not only output 4K streams at all times. The actual resolution transmitted depends on the image format requested by the connected host computer or application. The refresh rate of most webcams/video bars is always 30Hz, regardless of the image resolution. However, some cameras, especially those designed not exclusively for video communication, but also for other professional applications (live events, recording, etc.), may also be able to output different refresh rates such as 24Hz, 25Hz or 60Hz. This is often the case with high-quality PTZ cameras, which have an HDMI port and other port options in addition to a pure USB output.
Please refer to the owner's manual of your third-party device to find out how to adjust the parameters accordingly so that they are compatible with Klick&Show are. Klick&Show Base devices require Full HD output at 30Hz as part of actual online meetings, plus smaller resolutions for preview purposes from a connected third-party device.
Resolutions higher than Full-HD @ 30Hz are ignored, as they are not used by currently used UC applications (e.g. Microsoft Teams).
USB Transfer Mode: Isochronous
Support of the UAC/UVC profile,
according to USB Video Device Class and USB Audio Device Class Definition
(Note: K-FX is compatible with UVC 1.0 / UVC 1.1; K-FX Plus is compatible with UVC 1.0 / UVC 1.1 / UVC 1.5)
Video encoding in M-JPEG or YUV format
Video streams must be delivered in M-JPEG or YUV format. H.264 video streams are not supported to keep possible latencies low.
Integrated AEC (Active Echo Cancellation)
Only USB devices whose USB input/output signal path is equipped with an integrated AEC (Active Echo Cancellation) are supported, e.g. video soundbars, speakerphones, audio room solution with AEC to ensure good speech intelligibility for remote participants during online meetings.

Note on Choosing Third-Party USB Devices:
Online meetings according to the BYOM principle are characterized by the wireless use of USB video and audio equipment with one's own laptop and the UC application installed on it , such as Teams, Zoom, Webex and more.
Accordingly, connected USB devices only have the task of transmitting corresponding video and audio signals on the Klick&Show base device, which are then transmitted wirelessly from the base to the laptop.

A selection of compatible, but also unsuitable USB devices Kindermann on www.KlickandShow.com in the following document: List of compatible UC devices.pdf. This document attempts to show a representative selection of suitable devices – but naturally does not claim to be complete, due to the large number of third-party devices available on the market.

When choosing a suitable device, make sure that it meets the above criteria well. Less expedient – and therefore in many cases unsuitable – are third-party devices in particular that go beyond the actual Klick&Show The required provision of video and audio streams was designed by the manufacturer as an independent, full-fledged conferencing system . While such devices usually have a similar appearance to a "passive" video bar, they include their own internal processor unit, user interface, and pre-installed UC apps to enable online meetings to be conducted autonomously. This way of conducting an online meeting does not fall under the name "BYOM".
Examples of this are so-called "all-in-one" video bars, but interactive displays with integrated video conferencing functionality can also fall into this area.

Apart from the fact that such "all-in-one" devices represent unnecessary additional costs compared to "normal" video bars for BYOM use on a Klick&Show device of the K-FX series, such "additional" functions and internal algorithms are in conflict with the Klick&Show required to provide signals.
A general statement on compatibility cannot be made for such cases.

Despite the efforts of Kindermann for the greatest possible compatibility, incompatibilities are to be expected in individual cases. It is a good practice to test the compatibility of third-party devices in a test setup BEFORE the actual on-site commissioning. In case of incompatibility, you should first check if a new firmware is available for your third-party device. Please read the third-party device's user manual in its entirety and see if your third-party device may be able to establish compatibility by changing the configuration. Depending on your third-party device, certain parameters could be changed, for example, via web interface or by buttons or by an infrared remote control.
Examples of possible customizations you could try include:
– Switching USB output from mono to stereo
– Performing an acoustic room measurement
– Changing the video compression and setting the above parameters
–etc.

Klick&Show K-FX Series devices do not have any additional setting options to solve an existing incompatibility with a third-party device. Therefore, in the event of a persistent incompatibility, consider choosing another third-party device.

3.4 Network requirements

If the transmission of subscriber content is either partially or completely via the company network, please remember to provide sufficient bandwidth in the network!
To estimate the required bandwidth, we distinguish between the required bandwidth for the content originating from the user's laptop (upstream, directed towards the base) and the backward content (downstream, directed from the base to the user).
The "upstream" includes "presentations" (BYOD), the downstream includes the rear-facing camera/audio stream for BYOM meetings.

Upstream Data Rates:

The "upstream" data rates are through Klick&Show and are subject to a dynamic dependent on the concrete content, depending on whether the content is "static" or "moving", as follows:

Transmission via Full-HD Transmitter:
– static content (e.g. text): approx. 0~800 kbps
– low-movement, typical contents: approx. 1600~4000 kbps
– Highly moving content (fast video): approx. 8000~16000 kbps
Transmission via 4K transmitter:
– static content (e.g. text): approx. 0~800 kbps
– low-movement, typical contents: approx. 8000~16000 kbps
– Highly moving content (fast video): approx. 12000~32000 kbps
Transmission via Klick&Show App (Software Client):
– "Fast" mode: approx. 100~4000 kbps
– "Quality" mode, static content: approx. 100~500 kbps
– "Quality" mode, moving content: approx. 8000~16000 kbps

In all cases, the data rate can be as high as 80 Mbps in short-term peaks for the best possible video quality.

Upstream Data Rates:

The required data rate depends on the video bar / camera used, less than Klick&Show. In the vast majority of cases, USB conference devices perform internal data compression to pass on video data via USB and then transmit the data in the video formats "MJPEG" or "H.264". This already compressed data is processed by Klick&Show and are typically between 2000~12000Kbps.

In short-term peaks, the data rate can also be higher. The data rate is comparatively low, as online meeting platforms (Teams, Zoom, etc.) only use resolutions up to max. 1080p30 and Klick&Show therefore only retrieves a video stream in this required resolution from the connected USB device (even if the USB camera should have a 4K image sensor).

Only in special cases do USB video bars or PTZ cameras also output uncompressed data in the so-called YUV format. Data rates are then natively typical 80000~130000 kbps. In order to avoid unnecessarily high grid utilization in such cases, Klick&Show devices of the K-FX series automatically compress data into MJPEG format through "quasi-real-time".

Overview of connectors, buttons and status LEDs of Klick&Show Transmitters

All transmitter types allow you to mirror the primary or extended desktop. The hardware-accelerated signal processing integrated in the transmitters (except USB-A transmitters) ensures radio transmission with particularly low latency, so that despite the wireless signal transmission, your screen is mirrored in brilliant quality with up to 4K resolution with practically no visible latency, which is an outstanding feature of Klick&Show Represents. The optionally available Klick&Show Tray-4K.
Klick&Show 4K transmitters enable the mirroring of content in particularly high resolution. Its design features a multi-color LED status indicator and, in addition to the show button, 2 function buttons to trigger additional functions.

Before using it for the first time, it must be ensured that a transmitter is paired with a base unit to enable communication between the base and the transmitter. Details on this are described in Chapter 5.9 .

hint:
The formerly, since 2017 Klick&Show USB-A Transmitter is no longer available as of August 2023. The USB-A transmitter was intended to be connected to the USB-A data socket of a computer. Since there is no native video output to laptops, a transfer of the laptop screen is only possible in conjunction with the Klick&Show Software client possible. Existing Klick&Show USB-A transmitters are compatible with the base device, which is no longer available Klick&Show K-10S and to the Klick&Show K-40 base unit, but not to newer base units.

Status LED in the transmitter

All Klick&Show Transmitters have integrated LEDs to indicate the operating status to the user. Full HD transmitters have a centrally located dual-color LED status display and additional vibration feedback, 4K transmitters have a ring-shaped multi-color LED status display. The LED status indicators have the following meaning:

Permanently green: Ready for transfer
Permanently red: Active transmission
At the base: Pairing is finished, you can pull the transmitter off the base

Flashing green – on the computer:
– 100ms ON; 300ms OFF = Initialization/Connection Establishment
– 500ms ON; 800ms OFF = Connect to Wi-Fi
– 200ms ON; 800ms AUS = Get IP
– 800ms ON; 200ms OFF = establish communication to the base
– 300ms ON; 100ms OFF = No communication between PC/laptop and transmitter
Slowly pulsating blue: Camera transmission active.
The connected computer is ready to conduct a BYOM online meeting (4K transmitter only, in combination with Klick&Show K-FX series base units).

hint:
The Klick&Show HDMI transmitters can be used on almost any device with an HDMI output. If the device does not have a USB port that can provide the power supply, you can use a standard USB power supply or a power bank.
Klick&Show USB-C transmitters can be operated on any device that supports the so-called "DisplayPort Alternate Mode" for native graphics output on the USB-C port. In addition to PCs or laptops, this also includes mobile devices such as tablets or smartphones.

5. Installation

5.1 Installation of the basic device

The basic device can be placed on a table or mounted on the wall, for example.

hint:
Please position the base as close to the display device as possible to avoid long HDMI cable runs and resulting problems.

Tools needed for wall mounting:

• A drill (depending on the type and nature of the wall)
• Screwdriver or cordless screwdriver suitable for the mounting screws

Required mounting accessories (not included):

• 2 x screws (recommended head diameter: 7 mm)
• 2 x Matching dowels

Installation:

Drill two holes according to the drawing.
Turn on the mounting screws. Please leave about 4 mm of space between the wall and the screw head so that the base can be inserted in between.
Place the base device on the wall so that the screw heads of the two mounting screws reach into the holes of the base. Gently press the device against the wall and slide it down or to the side (depending on the mounting situation).
If the base is too loose, turn the screws a little further.

5.1.1 Installation and alignment of the WLAN antennas

In order to avoid damage during transport, the antennas are supplied loose and must be installed to optimize reception.

The antennas should be installed at least 50 cm away from metallic surfaces to avoid unwanted reflections. Likewise, at least a distance of 1 meter to other radio systems in the same frequency band should be maintained (e.B. WLAN access points).
We recommend a direct line of sight between the base and transmitters and the mobile devices.
The WLAN antennas used are so-called omnidirectional omnidirectional omnidirectional emitters. The radiation is circular for each antenna on a perpendicular plane to the antenna. The radiation is NOT along the longitudinal axis of the antenna. Due to this special dispersion characteristic, you should use the Klick&Show Base as shown below.

The two outer antennas should be turned about 30-40° to the side as shown and any middle antenna (depending on the type of base device) should remain perpendicular to the sitting position of the participants.
The antennas must be aligned accordingly, if in exceptional cases an installation of the antennas Klick&Show base above the subscriber's seating position (e.g. when mounted on the ceiling near a projector).
When installing a Klick&Show base within an area shielded from radio waves (e.g. 19 inch built-in cabinet made of metal or behind a large display with metal back panel), considerable quality losses in WLAN transmission are to be expected ("Faraday cage"). If such an installation situation is unavoidable, the supplied WLAN antennas should be positioned outside the shielding area, either by positioning the base appropriately or even remotely from the base using antenna extension cables.
For more information, see the white paper "Using WiFi extension cables".

5.2 Power supply

The following universal power supplies for mains voltage 100 – 240 VAC are included, with various regional adapter attachments:
K-FX / K-FX Plus: 12 VDC / 3A,
K-40 / K-WM: 12 VDC / 1.5A

Adapter Types:

Mount the required type plug adapter of your country.
Connect the power supply to the base device.
Plug the power supply into a suitable socket.

hint:
As soon as the power supply is active, the basic device (boot process) starts.

5.3 Power over Ethernet (PoE):

If the network switch supports PoE (Power over Ethernet), the power supply of the Klick&Show can also be carried out via the Ethernet port marked with PoE(PD). Depending on the type of base, this can be LAN 1 or LAN 2. The plug-in power supply is then not required.

hint:
Klick&Show K-40 / K-WM base units require a power supply according to PoE 802.af standard.
Klick&Show K-FX / K-FX Plus base devices require a power supply in accordance with PoE 802.3at (PoE+) in the case of connected USB UC devices.

5.4 HDMI port

Connect the HDMI output of the base to a display or projector using a suitable HDMI cable. In addition to the primary output MAIN HDMI OUT, K-FX Plus also offers a SUB HDMI OUT for connecting an optional secondary display device.

hint:
All Klick&Show Base device types support HDMI 2.0 output resolution up to 4K (3840 x 2160 pixels) at 60Hz refresh rate and chroma subsampling (4:4:4) for the main monitor.
Klick&Show K-FX Plus also offers a SUB-monitor output with 1080P@60 Hz (4:4:4) resolution.
Please make sure to use suitable cables that can transmit this resolution, especially for longer cable runs.

**HDMI connection of a display device (example K-FX)**

5.5 Audio connectors

The transmitters or the Klick&Show app transmit the video signal from the computer along with the audio signal to the base device. Even when using native transmission protocols such as Airplay, Miracast and GoogleCast, audio and video can be transmitted together.

HDMI Audio Output:
Image and sound are transmitted digitally via HDMI. A playback device, such as a display with speakers, can reproduce the sound directly.

Analog Audio Output:
The tone is output analogue at the "LINE OUT" jack socket. Active speakers or existing analogue audio systems can be connected here.

USB Audio:
Is a USB audio conferencing system attached to a base of the Klick&Show K-FX series, the audio output is done via it. This ensures that when conducting an online meeting, an effective suppression of echoes from the other side is possible through the USB audio conferencing device used.

Audio configuration on PC/laptop:
In the factory setting, Klick&Show the computer's internal speaker and transmits the sound to the Klick&Show base as soon as an image is transferred. If the transmitter is disconnected or the Klick&Show app closes, the previous audio configuration of the computer is restored.

Hint: If no audio is output via the Klick&Show, please check your computer's audio configuration. Here, the device must "Klick&Show" must be selected.
You can adjust the volume via the audio settings of your computer, tablet or smartphone.

5.6 LAN connection

The base can be connected to a network via CAT cable.
Depending on the network configuration, wired Network services are also available via Wi-Fi (bridging).

The network connections can be used for:

Network integration of the base in guest or corporate network
Over-the-air update (OTA) of the base
Global administration of many devices using Klick&Show ManageTool Software
Individual access to individual base devices via the internal WebUI for configuration
Telnet control of the base

Klick&Show has two physically separate network interfaces, each with its own MAC address, and can therefore be connected to two separate networks. The IP addresses through which the Klick&Show from the respective network are displayed on the home screen.

**Network connection status in the home screen (example K-FX Plus)**

hint:
Details on network configuration can be found in the chapter WebUI.

5.7 Use of touch screens (touchback)

Klick&Show In addition to image and audio signals, it also transmits touch inputs simultaneously via an interactive display called "touchback". Klick&Show supports the USB-HID protocol. This can be used, for example, to connect interactive touch displays, projectors or whiteboards, but also a mouse to the base via USB in order to

take over the functions of a mouse, perform multi-touch gestures*, work interactively, etc.
In this way, the contents of an actively played participant laptop can be operated remotely via an interactive main display device. If several laptops are mirrored simultaneously to the main display in split mode at the same time, each laptop can be operated individually from a distance.
to use the moderator function.
to use the integrated whiteboard/annotation app.
Onscreen system messages to confirm.

Klick&Show Base devices with 1 HDMI output support connection to 1 interactive display. K-FX Plus can be connected to 2 interactive displays due to its dual-screen output.

hint:
*The specific range of functions depends on the range of functions of the touch display, the selected connection and the operating system.

Klick&Show supports the touchback function via the following connection types:
1. Klick&Show App for Windows (10-point multi-touch)
2. Klick&Show App for MacOS (1 touchpoint)
3. Miracast on Windows laptops (1 touch point)

5.8 Using USB Cameras and Audio Conferencing Systems (K-FX Series)

Klick&Show K-FX Series devices transform conventional conference rooms into hybrid meeting rooms, facilitating collaboration between the office and remote participants. You wirelessly connect your notebook to the display and the professional USB camera and audio solution in the room.

This approach is called BYOM (Bring Your Own Meeting). At BYOM, employees can make calls with their own account on their preferred UC platform, whether it's Microsoft Teams, Zoom, Cisco Webex or Google Meet, etc. This also makes spontaneous participation in a hybrid meeting in the conference room child's play.

Klick&Show Devices of the K-FX series allow the use of either USB video bars (all-in-one) or alternatively separate combinations of USB camera and USB speakerphone, etc. which can be connected via USB cable to the rear USB 3.0 / USB device connectors of compatible Klick&Show basic devices.
With a PC or notebook, these USB conference devices can then be used wirelessly for BYOM (Bring Your Own Meeting) online meetings thanks to the USB-over-WiFi function, as if they were directly connected, with the UC application (e.g. Teams, Zoom, etc.) running on the user's laptop.

Connection of a combination of USB camera and USB speakerphone for BYOM

The following device classes are supported:

Audio & video in one device (built-in devices)
- 1. USB video soundbars
- 2. USB-PTZ system solutions incl. microphone and loudspeaker and integrated echo cancelling (AEC)
Video only
- 3. USB-PTZ cameras
- 4. USB webcams (with microphone)
Audio only
- 5. Integrated audio room solution with AEC
- 6. Speakerphones
A combination of the "Video Only" and "Audio Only" solutions.

hint:
The use of a USB webcam with integrated microphones and the speakers of a display is made possible by Klick&Show K-FX devices, in this case only the video function is provided wirelessly. This ensures that the suppression of echoes from the opposing side during online meetings is not affected. Details can be found in the Chapter 3.1.

5.9 Pairing the transmitters (K-FX series, K-40)

Before using it for the first time, it must be ensured that a transmitter is paired with a base unit to enable communication between the base and the transmitter. To pair, connect a transmitter to one of the front or side USB ports of the base unit, as shown below:

Pairing a USB-C transmitter before first use (K-FX Series, K-40)

Pairing an HDMI Transmitter Before First Use (K-FX Series, K-40)

Please follow the appropriate instructions that appear on the main display during the pairing process and do not disconnect the transmitter before a corresponding success message appears.

During a pairing (also called "pairing"), there are essentially 3 operations:

The base device checks whether the transmitter has the appropriate firmware.
If necessary, a firmware update is carried out automatically.
The base device checks whether the internal memory of the transmitter is formatted appropriately.
If necessary, the formatting is automatically adjusted.
The base device configures the WiFi parameters required for communication.

Only after successful pairing is a transmitter able to communicate with a base device and, when used on a laptop, transmit its image content.

transmitters that are part of a "kit version" of Klick&Show come pre-paired and can be used immediately. In any case, separately purchased transmitters must first be paired with the base. Re-mating is necessary in all cases if:

the base device receives a new firmware
(this may also provide and require new firmware for the transmitters)
A WLAN network parameter has been changed in the WebUI of the base
(for example, a WiFi channel or network mode)

A transmitter can only be paired with a single base device at any given time, and therefore can only connect to that base, which is an essential security feature. In typical user scenarios, a transmitter therefore remains permanently paired with a specific base device.
However, it is possible to operate a transmitter either temporarily or permanently on another base device if the previously described pairing process is carried out again on the other base device.

In the course of a pairing, the transmitters are set to match the respective Klick&Show base device – and thus suitable for later use – pre-formatted as follows:

Pairing to Klick&Show K-40:
The transmitters are being prepared for the exclusive use of screen sharing (BYOD).
In doing so, Klick&Show HDMI and USB-C transmitters provide completely software- and driver-free mirroring of content. When such a transmitter is connected to the video output of the laptop, they are recognized like an external PC monitor, whereupon a native graphics output is performed. Click the show button to wirelessly mirror your laptop's live content to the main screen. All transmitter types allow you to mirror the primary or extended desktop. The hardware-accelerated signal processing integrated in the transmitters (except USB-A transmitters) ensures radio transmission with particularly low latency.
Since no software/drivers are required in the described use case, the internal memory of a transmitter is deactivated during a pairing process with a K-40 Series base unit.
Pairing to Klick&Show K-FX Series Devices:
The transmitters will be prepared for the use of "Screen Sharing" (BYOD) and "USB Conferencing" (BYOM).
In this context, a Klick&Show K-FX Series system, in addition to the BYOD use case described above, also allows USB camera/audio signals to be transferred back to the laptop (BYOM), which requires software/drivers on the user's laptop.
The software components required for this are provided on an internal memory of the transmitter, which is formatted as a non-writable virtual CD-ROM memory during the pairing process with a K-FX series base device.

Even with K-FX series devices, the actual screen sharing (BYOD) continues to be driverless, whereby the CD-ROM and the software components on it remain unused.

hint:
Firmware updates for the transmitters are also pushed to the transmitters in the background during use.
For installations with multiple devices, we recommend using the ManageTool. This allows all transmitters to be connected to any base from the workstation.

HDMI transmitter (4K or Full HD)
Compatible with device series Klick&Show K-FX and K-40, no software required for screen sharing.
Can be used with laptops and other devices with HDMI output, regardless of the operating system.
USB-C transmitter (4K or Full HD)
Compatible with device series Klick&Show K-FX and K-40, no software required for screen sharing.
Can be used with laptops and mobile devices that support the so-called "DisplayPort Alternate Mode" graphics output on the USB-C output, regardless of the operating system.
USB-A Transmitter *
Compatible with K-40, requires Klick&Show App for Windows or macOS.
^{*) Note: As of August 2023, the USB-A transmitter is no longer available as an accessory.}
Klick&Show App (software client)
Compatible with all Klick&Show basic devices.
For purely software-based presentations on Windows and MacOS.
(In addition, required for BYOM online meetings to receive USB video/audio streams from USB devices connected to the base).

6.2.1 Screen Sharing via HDMI and USB-C Transmitter (K-FX Series, K-40)

First, make sure that all transmitters are properly connected to their Klick&Show base device have been paired.
Connect the HDMI transmitter to the HDMI and USB-A interface or the USB-C transmitter to the USB-C interface of your computer and wait until the transmitter turns solid green after about 5 seconds.

Press the transmitter's show button to start the broadcast. The transmitter will confirm the activation by changing the color of the LED to red.
The screen will now be cast and displayed on the main display connected to the base device. To end the transmission, press the show button on the transmitter again.

hint:
The HDMI and USB-C transmitters behave like an external monitor on the computer. No software is required for image transfer. As with connecting external monitors, you can decide whether you want to mirror the content of the primary desktop to the main display or the extended desktop.
To do this, select the keyboard shortcut Windows + P on Windows and go to macOS > SystemPreferences,clickMonitors,and then clickArrange.

Hint:
A USB-C transmitter can also be used in conjunction with Chromebooks, tablets, smartphones, etc. that have a USB-C port. The specific range of functions depends on the hardware of your device and the respective software. For video transmission, the USB-C port of your device must support the so-called DisplayPort alternate mode mode, which allows native graphics output on the USB-C port. This mode may not be available on older laptops or may not be available on all existing USB-C ports on your user device.
For the functionality of your device, please refer to the manual.
Whether your device supports touchback depends primarily on the operating system.

6.2.2 Screen Sharing via USB-A Transmitter* (K-40)

Hint:
^{*) The USB-A transmitter is no longer available as of August 2023.}

Unlike the HDMI and USB-C transmitters, the USB-A transmitter requires software that captures the screen content several times per second (screen grabbing) and encodes it into a video stream. The USB-A transmitter then transmits this video stream via WLAN to the compatible Klick&Show K-40 base unit, which outputs the captured content via HDMI to the display device.
The required software is the Klick&Show Software client available for Windows and macOS operating systems.

A description of the commissioning and use of the Klick&Show App can be found in chapter 6.2.3. (for Windows) or in chapter 6.2.4 (for MacOS).

If you Klick&Show K-40 in conjunction with a USB-A transmitter for the first time, you must first use the Klick&Show Run the app . If the program was executed once, the Klick&Show app is automatically started when the transmitter is then plugged in.

Hint:
In order to carry out the Klick&Show app, no administrator rights are required. However, an entry is made in the Windows Registry. In the Autostart section, the service Klick&Show_AutoServiceC3.exe that ensures that when the USB-A transmitter is reconnected, the Klick&Show Client starts automatically.
For example, if a group policy (e.g. via Active Directory) blocks the installation of "automatically starting software", you can switch to the version„Klick&Show-Portable" for Windows. This does not require any installation at all. However, the "Portable" version of the client must be started manually before each use, which limits the user's ease of use.

Plug the transmitter into a USB-A port of your computer. As soon as the LED indicator of the transmitter lights up constantly green and the Klick&Show app has been started automatically, the system is ready for use. When using a transmitter previously paired with the base, no PIN entry is required.

Now you can press the show button of the transmitter to activate the broadcast or click with the mouse on the virtual green show button in the Klick&show Software Client. The transmitter will confirm the activation with a color change to red. The corresponding show button of the Klick&Show App will also turn red.
Your computer's screen will now be transferred to the base and displayed on the main connected display. The computer's user name appears briefly.
To end the broadcast, press the transmitter's show button again or click the app's red "Stop" button.

After use, you can simply unplug the transmitter from your computer, including the Klick&Show app.

6.2.3 Screen Sharing via Klick&Show App for Windows and macOS

Hint: The Klick&Show App is available for Windows and macOS. For both operating systems, the app is identical in the essential functions, but not all settings are available for MacOS.
The following chapter uses screenshots of the Klick&Show App for Windows for illustration. For MacOS, the explanations apply mutatis mutandis. Differences will be pointed out in individual cases.

The Klick&Show App enables software-based mirroring of image content using your computer's Wi-Fi connection. If the Klick&Show app is not yet available on your Windows or macOS computer, you have the following options to choose from:

By download from www.klickandshow.com/client/
Download from the Klick&Show Base
To do this, enter the IP address displayed on the home screen in the browser and download the app "Klick&Show" to match your operating system.

**Download the Klick&Show app from the internal web server of the Klick&Show Base unit**

To use it, first make sure that your computer is on the same network of a Klick&Show base, as described at the beginning of the chapter. To do this, connect your computer to the "guest" or "internal" WLAN network, which is displayed on the home screen. Start the Klick&Show App by double-clicking on the app icon: .

When starting the app, it first searches the network for available base stations and lists found devices. Now click on the corresponding "Connect" button to log in to the desired Klick&Show base station in your room. Now you will be asked to enter the PIN which is displayed in the status bar of the home screen of your base unit (see above, chapter "Home screen)"). The PIN prevents unauthorized access to the Klick&Show system by people who are outside the room.

Hint:
If the desired Klick&Show Base in the list of available base stations, you can also manually enter their IP address in the search box:

In this case, your computer is either not connected to the same network (segment) or there are network-side restrictions that block an automatic search.
In this case, please contact your network administrator.

The Klick&Show App is now ready for image transfer.
To start mirroring your image content to the main display, click the "Show" button. The button color changes to red and the screen content is transmitted. The name of the logged in user is briefly displayed on the main display.

You can minimize the app window.
In the Windows taskbar you can still see whether the screen content is being transmitted or not .
In the MacOS Status Bar shows an icon the current connection status.

To stop mirroring content from your computer to the main display, click "Stop". The button color is green again.
Your computer's network connection to the Klick&Show Basistation is maintained in order to enable a new endoscopy quickly.

To end the Klick&Show app, click on the Close icon (X) or in the Windows system or in the MacOS status bar with the right mouse button on the Icon and then click Exit. A confirmation dialog follows.

Advanced features of the Klick&Show App for Windows and MacOS

The Klick&Show In addition to the most important "Show/Stop" function, the app offers various tools and options that you can use as part of your presentation. The following three frequently used presentation functions are arranged in direct access:

Desktop / Window:
In the initial state, when the image content is mirrored, the complete "Desktop". Alternatively, however, you can use the operating mode "Window" only Select a specific application window of a previously opened application for mirroring. This mode of operation is advantageous if you don't want to give other participants a view of your entire desktop. The switching of the operating modes is done by means of the buttons .
If you are in the "Window" mode, a message will be displayed on the main display if you minimize the current application window on your computer and consequently no content would be visible.
Freeze:
A frequently used function is the Short-term pause of the transmission. In this case, your connection to the Klick&Show Base station and the image content is temporarily frozen. This gives you the ability to search for data on your computer without giving other participants insights into your computer.
As an additional benefit, the access parameters are displayed at the top of the screen when the pause function is triggered. This will allow participants who use either Klick&Show app or native protocols, help is offered, and the parameters required for a connection, such as device name and PIN, are briefly displayed.
The Pause Transmission / Freeze function is triggered by the button shown below. Pressing it again cancels the pause .
Fullscreen / Split:
In the special situation of a split-screen display, where the content of several participants is visible on the main display at the same time, you can activate the Temporarily display the "Full Screen" button to fill the format. Pressing it again restores the split image display. The switchover is carried out by means of .
The split image display is useful for comparing content with each other. Up to 4 pieces of content can be displayed on a main monitor.

click the gear icon at the bottom left of the app to select the "settings".

Options:

Extended screen
Note: this function is only available for the Klick&Show App is available for Windows, but not for MacOS.
If this option is selected, the Klick&Show like an external monitor, i.e. a second "virtual" screen is set up and transmitted.
If you want to make the transfer with Klick&Show , the extended desktop will remain active until you either deselect the "Extended Screen" function in the app or select the Klick&Show Close the app.
Alternatively, you can use the keyboard shortcut "Windows + P" in the Windows configuration to select "PC screen only" or "Duplicate".

hint:
When activating the "Extended Screen" function for the first time in the software-based presentation with the Klick&Show app, a driver is installed.
The installation process requires administrator rights.

Keep aspect ratio:
This option is active by default. This ensures that the image on the source device and on the display have the same proportions. If you deselect the function, the image is stretched to the overall width and thus possibly distorted.

Avoid mouse latency:
The option is active by default. The mouse cursor is displayed without any noticeable delay (~20 ms) during movements, which significantly improves ergonomics.
However, the mouse cursor is always displayed as an arrow symbol on the main display in all applications, regardless of whether it changes its shape on the PC monitor.

Disabled: The shape of the mouse cursor (e.g. arrow or hand) on the display corresponds to the actual shape in the application. The movement of the pointer occurs with a small delay (100 – 150 ms).
Transmission Quality:
This option allows you to choose between two presets for the encoded transmission of image information.

– Fluid Priority: For fast-moving images, the quality is optimized for smooth display with only a slight delay (latency).

– Quality priority: For the highest possible playback quality, the data rate is increased for fast-changing images, such as a video transmission. This can lead to a slight but noticeable delay (latency).

6.2.4 Additional operating instructions for the Klick&Show App

If the Klick&Show app version does not match the firmware of the base, you will be notified by a message after starting the app:

In this case, delete the previous version and install the current one.

Hint:
The message only serves as an indication of functions that go beyond the mere mirroring of image content and were added in later software versions. So, a user can temporarily ignore this message and continue their presentation unhindered as long as they just want to mirror the contents of their device.

Right-click on the icon in the Windows taskbar or macOS status bar opens the Klick&Show Context menu. The software tells you versions of the base device, the transmitters and the Klick&Show App.

6.3 USB Conferencing (K-FX Series)

Klick&Show K-FX series devices, including Klick&Show K-FX and K-FX Plus, transform traditional conference rooms into hybrid meeting rooms, facilitating collaboration between the office and remote participants. The USB conferencing function connects your laptop to existing USB devices in the room, such as video or sound bars, cameras and hands-free systems.

This concept, known as BYOM (Bring Your Own Meeting), allows employees to make audio/video conferencing calls through their own account on their preferred UCC platform, be it Microsoft Teams, Zoom, Cisco Webex, or Google Meet, etc.

Hint:
The conferencing function (BYOM – Bring Your Own Meeting), i.e. the wireless return transmission of USB camera and USB audio conferencing signals for UC conferences, is only available for Windows 10 / 11 and MacOS.
Aother operating systems (e.g. Linux) are not supported.

For Windows and MacOS, this requires the installation of virtual video and audio device drivers before using them for the first time, as described below:
a) Windows Plug&Play installation with transmitter (no administrator rights required),
b) macOS and Windows manual installation (administrator privileges required).

In addition to these installation methods intended for the individual user, the Klick&Show App in Microsoft Installer Format (.msi) is available in the download area on www.KlickandShow.com , which can be used by IT administrators as part of a company-wide rollout.

If, despite the correct procedure according to the following steps, an installation on your Windows or MacOS computer is unsuccessful in individual cases, first check whether an antivirus program on your computer may be preventing the correct installation.

6.3.1 Commissioning of USB conferencing via HDMI or USB-C transmitters (K-FX series)

Connect the transmitter to the computer as described in chapter 6.2.1 .
When transmitters are used in BYOM mode, they take over the (driverless) mirroring of device contents to the main display, while the Klick&Show app receives the data streams transmitted backwards from the USB devices via laptop WiFi and makes them available on the laptop for use by web conferencing applications such as Microsoft Teams, Zoom, WebEX, etc.

After plugging the transmitter into your computer, depending on the operating system, select the desired driver installation for USB conferencing:

Installation of virtual Klick&Show Device drivers for USB conferencing: 1a) without administration rights (Windows) or 1b) with administration rights (macOS / Windows)

1a) Windows Plug&Play Installation
(no administrator rights required)

An automatic installation of the virtual device drivers required for USB conferencing Klick&Show app using Windows Plug&Play is possible using the firmware versions available from August 2024 for Klick&Show Basic devices of the K-FX series.

To use this type of installation, the following requirements must be met:

Your laptop must be connected to the internet,
The Windows Update Service must not be disabled

Under Windows 10/11, an AutoPlay notification window automatically appears when the transmitter is connected. The Windows Autoplay hint window can be ignored as part of the Windows Plug and Play installation.
After plugging in the transmitter, the automatic installation of the drivers typically takes place within about 2-3 minutes.
A successful installation is recognizable by the appearance of the Klick&Show icon in the Windows taskbar:

If the automatic installation has not taken place even after a waiting period of 3 minutes, initiate the process by pressing the "settings" open , then "Windows Update" and here "Check for updates".

1b) macOS / Windows manual installation
(Administrator rights required)

If the prerequisites for an automatic Plug & Play installation are not met under Windows (no Internet access, Windows Update service disabled), a manual installation is possible for which administrator rights are required. On macOS, only manual installation is possible.

Under Windows 10/11, an AutoPlay notification window automatically appears when connecting the transmitter (triggered by the CD-ROM memory in the transmitter pre-formatted for K-FX series devices).
Click on the AutoPlay hint window and confirm the execution of WirelessMedia.exe from Klick&Show CD-ROM drive. If in rare cases the AutoPlay function is deactivated on your computer, either activate it beforehand or start the file WirelessMedia.exe manually from the Klick&Show CD-ROM drive by double-clicking via Windows Explorer.

**Windows AutoPlay message when connecting a transmitter (K-FX)**

**Display of the Klick&Show CD Drive in the Transmitter (K-FX)**

The Windows Autoplay hint window only needs to be observed the first time it is executed. After the first successful start-up, the autoplay hint can be ignored, as the already installed Klick&Show app automatically opens when plugging in a transmitter in the background.

If a USB camera and/or a USB audio conferencing system has been connected to the K-FX base, the software checks whether the necessary drivers are already installed on the system. The first time you use it, the Klick&Show Prompt you to install the drivers.

Klick&Show Setup Wizard for installing the virtual drivers for USB conferencing (example Windows)

Hint:
To use the conferencing (BYOM) functions under K-FX, administrator rights are required during manual installation.
Alternatively, the Klick&Show app and the function drivers for the Windows operating system can be pre-installed via central software distribution.
The MSI installation package can be found on a K-FX series download page.

After successful installation, a virtual camera "KLICK&SHOW Video" and a virtual audio device "KLICK&SHOW Audio" as a microphone or playback device.

**Virtual Klick&Show BYOM device drivers in Windows Device Manager**

hint:
Data transmission for screen sharing is carried out via the WLAN module integrated in the transmitter, but the rear transmission of USB data from the camera and audio conference is carried out separately directly via the computer's network connection.
That Klick&Show The K-FX series base device must be connected to the network either wired (LAN port 1 or 2) or wirelessly, so that the participant laptop used as the host computer of a UC meeting is both on the same network of the base (for receiving the USB devices data streams) and on the Internet (for conducting the UC meeting).

If the subscriber's laptop and base are already in the same network address range, a connection is immediately established to receive the USB devices' data streams. In the other case, if the laptop is connected to a foreign network at the beginning, from which the Klick&Show base, the Wi-Fi connection must be changed accordingly.

The Klick&Show The app then automatically notifies the user of the necessary network change and, after confirmation, also carries out the change independently. Usually, the Wi-Fi password is passed when pairing the transmitters, so that manual entry is not necessary.

For information on network configuration, see the chapter Network Settings.

6.3.2 Commissioning of USB conferencing via Klick&Show App for Windows and macOS (K-FX series)

The Klick&Show App enables software-based mirroring of image content using your computer's Wi-Fi connection, as well as back-directed transmission of USB camera/audio signals for USB conferencing.
If the Klick&Show app is not yet available on your Windows or macOS computer, you have the following options to choose from:

By download from www.klickandshow.com/client/
Download from the Klick&Show Base
To do this, enter the IP address displayed on the home screen in the browser and download the app "Klick&Show" to match your operating system.

If a USB camera and/or a USB audio conferencing product has already been connected to the K-FX Series Base Unit, the software will check whether the necessary drivers are already installed on the system. The first time you use it, the Klick&Show app will prompt you to install the drivers.

After successful installation, a virtual camera " KLICK&SHOW Video" and a virtual audio device "KLICK&SHOW Audio" as a microphone or playback device.

6.3.4 Basic Use of USB Conferencing (K-FX Series)

To wirelessly connect the USB camera or USB audio conferencing solution to Klick&Show In order to be able to use K-FX series devices, the last step is to change the device configuration of the UCC application.

Example Microsoft Teams:

Example Zoom:

In other UCC applications, the setting must be done accordingly.

Hint:
In all UCC software clients there is a test function for the audio and video setting. With this you can also ensure the correct functioning of Klick&Show test.
In order to understand the basic function of retransmitting USB video and audio signals from the Klick&Show To test K-FX Basis via the existing network to the laptop, the "Camera App" can also be used under Windows, for example.

Inside the UCC application, Klick&Show as the audio/video device until you manually select other available audio/video sources – even if you Klick&Show do not use it at the moment.

As soon as the camera or audio transmission is actually used (by a UCC application accessing the USB camera and audio conferencing devices), the camera icons in the Klick&Show app and in the status bar of the Klick&Show Homescreen on the main display.

6.3.5 Advanced USB Conferencing Features (K-FX Plus)

Klick&Show K-FX Plus provides particularly advanced USB conferencing features, which are described below.
To use these special functions, the function keys of the Klick&Show 4K transmitters are provided, which can be assigned to customer requirements in conjunction with K-FX Plus. Alternatively, some of the special functions can also be activated via the Klick&Show app, for example in a purely software-based use without a transmitter.

To configure the two function keys when using 4K transmitters, open the internal WebUI of your Klick&Show K-FX Plus Base Unit as described in Chapter 10 and call up the "Button Definition" subpage to perform the desired function assignment.

The dual-cam function allows the use and switching of 2 USB cameras during a UCC meeting, thus offering different perspectives for remote online participants through 2 switchable USB cameras. The switchover in the Klick&Show App is done by repeatedly clicking on the camera icon as shown below.

To view content sharing:
The "Content Sharing" function allows you to view the current content of the local Klick&Show Main display in your room can also be shared with remote participants of a UC meeting. After selecting the function via transmitter, function button or app button a browser window opens on the host laptop that contains the rear live stream of the main screen.

Browser window with live stream of local Klick&Show Main

Within the browser window, you have the option to switch between the stream of the MAIN display or the SUB display of a K-FX Plus base.
As the UC meeting progresses, you can now share this browser window as shared content in the UCC application you are using. In Teams, for example, this is done using "Share" (share content) = > window.

How to Use the View Content Sharing Feature in Microsoft Teams

USB Hub Switching:
Klick&Show K-FX Plus offers the possibility to pass on USB devices connected to the base unit (e.g. camera and audio devices) to a stationary PC. The USB devices can be used either for a wireless UC meeting according to the "BYOM principle" or for UC meetings hosted from a stationary PC. For more information, see the separate chapter USB Hub Switching.

hint:
Starting with macOS Monterey, Airplay only supports 4-digit PINs. In this case, a window is displayed when the connection is established, in which the 4-digit code is displayed. These are the last 4 digits of the 8-digit code (PIN).

6.6 Use of Miracast

Klick&Show Miracast supports both Miracast operating modes, the "WiFi direct mode" known from Consumer Electronics, in which a direct (peer-to-peer) connection is established between the transmitter and the receiver WLAN, and the professional infrastructure mode (MS MICE).

For MS MICE, the Klick&Show Base device must be connected to the corporate network and the user device is on the same network. The connection of the base device can either be established in access point mode via a LAN cable or one of the infrastructure modes is used, see Chapter 9.2.

K-FX Series base units already support these two modes as standard. For K-40 and K-WM, the optional USB Miracast WiFi adapter is required.

6.6.1 Using Miracast on Windows

To establish a connection via Miracast, you can optionally use the familiar key combination [Windows + P] and then click on the link marked in red. This will take you to the connection menu, which you can also call up directly with the key combination [Windows + K]. Select Klick&Show and, if necessary, enter the code that is displayed on the home screen.

Once connected, select the option "Allow mouse, keyboard, touch, and pen input on this device" to enable touchback via Miracast, for example, when using an interactive display connected to the base.

A black bar will appear at the top of the screen indicating the connection status.
In this case, the transmission can also be disconnected again. Alternatively, press [Windows + K] again.

6.6.2 Miracast on Android devices

Miracast is available on almost every Android device. However, depending on the manufacturer and Android version, it may be called differently.
In our example, we are using a smartphone with Android 10. Select the "Cast Screen" feature. The available devices are searched. Choose Klick&Show and enter if necessary. Enter the code that is displayed on the home screen.

An active transfer will be in the status bar displayed. To exit, disable the transfer.

6.7 Using Google Cast (ChromeCast)

GoogleCast (often referred to as ChromeCast) is currently available via the Google Chrome/Chromium browser on the ChromeOS, Windows, macOS and Linux platforms. Please install the browser on your computer if necessary.

Connect your device to the "Guest" or "Internal" Wi-Fi network that is displayed on the home screen.
If the Klick&Show Connected to a network via CAT cable, all other computers on that network also have access to the Klick&Show Base.

7. Splitscreen, Moderation & Tools

Klick&Show In addition to the basic screen sharing feature, it also offers other helpful tools that can help users present and contribute to a productive meeting.

7.1 Splitscreen

In certain situations, it may be useful to display more than one participant content on the main display, for example, to compare different content or to show supplementary information that is difficult to combine on one screen.

Supported here Klick&Show split-screen display of up to four sources simultaneously. You can make the selection of the number and display in the WebUI.
In the special case of K-FX Plus, it is possible to display up to 4+1 (or 1+4) content due to the support for 2 HDMI main displays. In particular, this allows 2 contents to be displayed in full format in a particularly easy to read way on 2 main displays.

The split-screen function is automatically activated as soon as more than one device transmits image content at the same time. The assignment of the positions is done automatically depending on the order of the presentation.
As soon as a fifth source wants to display itself, the content previously displayed first is replaced.

Hint:
To switch your screen from split-screen to full screen, you can press and hold the show button for 2 seconds on all transmitter types.
When using a 4K transmitter, the function button 1 ("-") is also assigned to this function for direct selection at the factory (K-40, K-FX), or can be configured accordingly with K-FX Plus.

In the Klick&Show app, the "Full Screen/Split" button performs the same function.

The WirelessMedia2 app for Android also offers a "fullscreen" button.

Airplay and Miracast do not support this feature, so all other devices have to separate so that these devices can present in full screen.

7.2 Moderation

hint:
For the best possible user experience, we recommend using the following functions in conjunction with a touch display.

To get to the moderation menu, tap on the arrow that appears on the right side of the screen (step 1).

At the bottom of the sidebar, the icons for selecting the whiteboard app and the annotation function can be selected (step 2).

The sidebar also shows all connected devices and can be displayed by the presenter by tapping with his finger on the interactive display (3). Whether a preview image is displayed depends on the setting or use of a transmitter. The moderation function is not available for Airplay and Miracast due to technology.

Note:
This feature can be disabled via the WebUI. In this case, no Pfleil or only a reduced menu is displayed, which allows access to the whiteboard and annotation function.

8. Service functions

8.1 Deleting the Klick&Show App for Windows and macOS

If you get an error message when plugging in a transmitter or running the app on your laptop, older software components may be causing a conflict on your computer. The specific procedure for removing such components depends on the operating system of the laptop and the previously selected type of installation.

For all subsequent cases, we provide the Windows and Mac Cleaner as a cleaning tool.

Hint: The cleanup can cause the computer to restart. Please close all unnecessary software applications beforehand.

Deleting the Klick&Show App for Windows

The procedure depends on the original type of installation and is carried out in either 1 or 2 steps. In any case, please check first whether there may be a previous "manual" installation (step 1) before proceeding to step 2.

1) Cleanup in case of earlier manual installation of the Klick&Show App:
Open the Windows Settings and select "Apps„. Check the list of installed apps for "Klick&Show„. If you find such an entry, click "∙∙∙, and then tap Uninstall. In the same way, check and uninstall possible entries of the former name "WirelessMedia„.

To clean up remaining Klick&Show software components, please proceed as described in step 2 below.

2) Cleanup in case of earlier Plug&Play installation of the Klick&Show App via transmitter:
To clean up Klick&Show Download the Windows and Mac Cleaner and run the file WindowClear.exe by double-clicking after unzipping the archive. Once launched, confirm that the program is running. When you run it, you will receive 2 alerts at the beginning and end of the cleanup process:

WindowClear.exe removes all virtual device drivers that are automatically installed for BYOM as well as autostart entries of the Windows registry.

Deleting the Klick&Show App for macOS

The procedure depends on the version of your macOS operating system.

Removing the Klick&Show App from macOS Ventura or earlier versions:
Download the Windows and Mac Cleaner and run the file MacClear.app after unzipping the archive.

Removing the Klick&Show App and system extensions from macOS Sonoma or newer versions:
Due to stricter security policies for macOS version 14.1 "Sonoma" or later, the end user must manually grant permission to use the Klick&Showapp and related system extensions as described below.

Step 1: Search Klick&Show.app in the Applications folder. Right-click on it to bring up the context menu:

Step 2: Select "Move to Trash", which will open a dialog box:

Step 3: Click "Next" and enter your Mac password in the pop-up message to uninstall the driver:

8.2 Restoring factory settings (reset)

A factory reset is triggered by pressing the reset button on the Klick&Show Base. Alternatively, you can also initiate a reset via the administration interface . Both paths lead to the same result.

Turn on the base device.
Once you see the home screen, press the reset button with a sharp object, such as a bent paper clip. Press and hold the button for at least 2 seconds until the "Factory Reset" message appears. Klick&Show will restart after another 3 seconds with the factory settings.

If you have no display connected, hold down the reset button until the LED display on the top lights up red to perform the reset.

Hint:
During the reset, the current firmware version is retained, but all configuration parameters are reinitialized and settings made are lost. Klick&Show must then be set up again. To simplify this process, you can back up the current system configuration in the WebUI beforehand and restore it after the reset.

After the factory reset, all transmitters must be paired with the base device again.

Although not mandatory, it is expressly recommended to perform a reset even after installing a new firmware in order to correctly initialize the parameters of new functions. Only then should the pairing of existing transmitters take place and the further configuration.

9. Introduction to Network Configuration

9.1 Basic rules for WLAN

To ensure that radio signals from different transmitters do not interfere with each other, "WLAN hygiene" is essential, i.e. You must ensure that only one access point transmits on each Wi-Fi channel and, if necessary, on the directly adjacent channels. Otherwise, there is a risk that signals from different transmitters will overlap and interfere with each other. In favorable cases, only the data rate decreases, in unfavorable cases the data transmission is temporarily interrupted.

There are various professional WLAN scanners on the market that help for a quick overview, but also free apps, such as the WiFi Analyzer, which visually display conflicts.

It is a good practice to start a Klick&Show system to analyze the network environment for frequencies/channels already in use, in order to then assign the Klick&Show system by configuring it in the WebUI.

Difference between 2.4 GHz and 5 GHz frequency band

Two frequency bands are available worldwide for the use of WLAN. Both have advantages and disadvantages.

2.4 GHz
- For technical reasons, longer range or better penetration
  due to the lower radio frequency
- Few canals, mostly heavily frequented
- Lower bandwidth per channel
- Oldest standard – highest distribution and compatibility
5 GHz
- Due to technical reasons, short range and poorer radio penetration
- More channels, usually less frequented
- More bandwidth per channel
- Compatible with modern, Wi-Fi-enabled devices

hint:
We recommend using a free channel in the 5 GHz band.

In order to achieve the best transmission quality, a clear "line of sight" between the Klick&Show base and transmitters or mobile devices, so that radio transmission can take place unhindered.

Avoid proximity to objects made of metal or other dense materials. In particular, an installation in

When installing a Klick&Show base within an area shielded from radio waves (e.g. 19 inch built-in cabinet made of metal or behind a large display with metal back panel), considerable quality losses in WLAN transmission are to be expected ("Faraday cage"). In such situations, it makes sense to install the antennas with an extension in a better place for reception, such as outside a tech rack.

Please pay particular attention to the explanations in chapter 5.1.1 Installation and alignment of the WLAN antennas.

9.2 Available Network Modes

Klick&Show supports three network modes:

Access Point Mode
- Access Point Mode (with bridging)
WLAN Infrastructures Fashion
LAN Infrastructures Fashion

In factory condition, all Klick&Show Base units are delivered with preset access point mode, whereby the base unit provides its own internal WLAN access point to which all transmitters, computers and mobile devices can connect.

There are several reasons why it may be useful to extend or change this factory default setting:

Providing a connection to the Internet for:
- Access to external information and content
- Conducting hybrid meetings (web conferences) with external participants (K-FX series only)
Providing a connection to the corporate network for:
- Access to local information and content
- Wireless use of USB conferencing devices in web conferencing (K-FX series only)
- Remote administration of multiple Klick&Show Devices
Automatic firmware update of Klick&Show
Use of separate networks for employees and guests
Targeted administration of used WLAN channels
... and more

Hint:
Depending on your Klick&Show device type (K-FX series, K-40, K-WM) and the intended usage scenario, a connection to the company network may be optional or mandatory. Therefore, please note the overview of the supported network modes and the options for connecting to the company network in the following chapters.

Which network mode is particularly advantageous depends on your personal usage scenario. The following chapters provide information on this. First of all, however, some general information:

The integrated access point offers particularly easy commissioning and use, so the access point mode is preset at the factory. This mode is distributed when there are only comparatively few rooms in a building with Klick&Show are to be equipped, all of which then use an independent WLAN. For additional functions (provision of Internet to connected devices, BYOM conferencing for devices of the K-FX series, remote administration, etc.), one (or two) additional wired network connection via LAN can be added at any time in access point mode. Existing transmitters are equipped with the Klick&Show access point, which is typically located in the same room, ensuring a high-signal Wi-Fi connection.
The two at Klick&Show available infrastructure modes (wireless infrastructure and LAN infrastructure) primarily disable the standalone access point of the Klick&Show Base. Instead, the basic devices are integrated into the company network either wirelessly or wired. This can be useful in larger rollouts where many Klick&Show systems can be used in a comparatively close radius. In such a scenario, there would be a risk that there would not be a sufficient number of free Wi-Fi channels available and that several devices would have to share the same Wi-Fi channels, which could lead to a loss of quality in transmission quality.
The use of infrastructure modes then leads to better "Wi-Fi hygiene", as the transmission of the Klick&Show data streams then run over the existing WLAN channels of the company network. However, it should be borne in mind that the required bandwidth must then also be ensured (see note below). In addition, the access point of the corporate network should not be located far away to ensure high signal strength and operational reliability for the transmission of near-real-time video, especially for the transmitters.
In both infrastructure modes, but also in access point mode after expansion with LAN connection, Klick&Show via the existing infrastructure and can be administered centrally. This is convenient and secure, as enterprise networks are usually actively administered and achieve a higher level of security.
For hybrid access from the guest network, Klick&Show for example, can be integrated into a separate network segment that can be reached from both the internal and the guest network.

Hint:
If the transmission of subscriber content is either partially or completely via the company network, please remember to provide sufficient bandwidth in the network! Information on this can be found in Chapter 3.1 Properties/Compatibility, there in the section "Requirements for the network".

In this context, you should be aware that if the base and especially the transmitters are connected wirelessly, their transmission/reception quality – and thus the resulting transmission quality – depends largely on the structural conditions (distance of the company access point and materials that can be penetrated by the WiFi signal). In particular, the function of the transmitters can be impaired in such cases, due to the comparatively compact integrated antennas. In the event of such an impairment, the use of the access point mode is recommended, whereby the transmitters are now coupled with the base in the immediate vicinity, possibly supplemented by further connections to the company network by means of LAN ports 1/2 and optional bridging.

hint:
The instructions for configuring the different modes can be found from Chapter 11.

9.2.1 Access Point Mode (Basic Configuration)

When you start it for the first time or after a factory reset, Klick&Show in access point mode, where the base unit provides its own WLAN access point to which all transmitters, computers and mobile devices connect. The parameters of this access point (SSID name, WLAN frequency range, WLAN channel) can be configured via the web menu of the Klick&Show Configure the base.

For additional functions (provision of Internet to connected devices, BYOM conferencing for K-FX series devices, remote administration, etc.), one (or two) additional wired network connections via LAN can be added at any time in access point mode . In this case, an additional "bridging" can be activated for one of the LAN ports, which is briefly explained below:

Without connecting the base to the corporate network, user devices that connect to the internal Klick&Show access point, initially no access to the Internet or any other network share.
However, such access can very easily be made possible by so-called "bridging". To do this, a wired connection must first be established from the corporate network to either LAN port 1 or LAN port 2 to provide these network services. Then, via the web menu of the Klick&Show base the bridging to one of the LAN ports can be enabled. Subscriber devices connected to the base access point can now connect to LAN-provided network services at the same time. See the following chapter 9.2.2 Access Point Mode with Bridging.

In access point mode, a connected LAN cable can open up further possibilities even without activated bridging , such as external access to the base for remote maintenance or the backward transmission of connected USB conference devices for BYOM calls in the event of Klick&Show K-FX series devices.

hint:
In AccessPoint mode, the 8-digit code (PIN) displayed on the home screen is also the Wi-Fi password.

Access Point Mode / Stand-Alone Operation

9.2.2 Access Point Mode with Bridging

Access Point Mode with Bridging to LAN Services (Internet)

In this configuration, the Klick&Show Base unit (K-FX, K-40, K-WM) additionally wired (CAT cable) connected to another network and the "bridging" for this LAN port is activated via the Klick&Show Web menu. This network connection is then established within the Klick&Show and is therefore also available to users who want to connect their device directly to the Klick&Show access point.

By connecting a wired network, it is very easy to divide the network into guest network and employee network in access point mode. However, enabling bridging can be a security risk in this case. Please note the following warning.

Connection of internal WiFi access point and LAN by bridging

ATTENTION:
It depends on the configuration of the wired network whether only the Internet access or the complete access to the company and/or campus network is shared in this way.
Therefore, please check this step very carefully and close the Klick&Show not without prior approval of the IT department to a network cable.
In this configuration, the WLAN password and thus possibly the complete access to your network is in plain text on the home screen!

In the WebUI configuration menu of the base, you can set whether the bridging should be done either from LAN port 1 or LAN port 2.

You can also operate both network accesses separately (without bridging), then the Klick&Show Base still accessible from the wired network. However, user terminals that are connected to the base's access point via Wi-Fi cannot use the services of the wired network.

Separation of internal WiFi access point and LAN without bridging

For example, a secure separation between the guest and company network can be realized. Guests and transmitters connect directly to the Wi-Fi of the Klick&Show Employees use the internal network infrastructure and thus retain their access to network drives, etc.

9.3 Infrastructure modes

The infrastructure modes allow you to: Klick&Show fully integrated into a structured network. This can be done via Wi-Fi or cable. The internal access point of the Klick&Show In both cases, the base is deactivated, or in the wireless infrastructure mode the WLAN functional unit of the base is only used as a "station" in client mode.

hint:
We recommend the use of infrastructure modes if the following criteria are met:

1. Existing, powerful, administered Wi-Fi network
2. Client devices are operated and administered over the same network
3. Use of many Klick&Show Appliances (in the immediate vicinity)

Please coordinate details as well as the necessary access authorizations and port permissions with the responsible network administrator.

9.3.1 Wireless Infrastructure Mode

In wireless infrastructure mode, the internal WLAN function unit of the Klick&Show Basis operates as a "station" in the "WLAN Client" mode and connects the base wirelessly to an existing access point of the company network. The transmission of content by means of Klick&Show Transmitter or Klick&Show App is thus also carried out via this network. The access parameters required for the external access point (SSID, password) are set during configuration via the web menu in the Klick&Show basis. The transmitters receive the necessary connection information to connect to the network through pairing.

Wireless Infrastructure Mode: for wireless connection of the base to the company network

In addition to the wireless connection between Klick&Show base and external access point in "Wireless Infrastructure Mode", additional wired network connections can be provided via LAN ports 1 and 2. Another external access point could also be connected here, for example to enable a separation of the employee and guest network. Both access points would then be able to enable connected participants to transmit content on an equal footing. When configuring in the web menu of the base, it can be determined whether the transmitters should be paired either via the wirelessly connected access point or via the wired access point on a LAN port.

9.3.2 LAN infrastructure mode

In LAN infrastructure mode, the internal WLAN function unit of the Klick&Show Base completely shut down. This can be useful if numerous other WLAN networks are already operating at a short distance and available channels may be occupied. In order to avoid conflicts in wireless data transmission and, as a result, a deterioration in the transmission quality of Klick&Show, the transmission can then be carried out in a targeted manner via an existing access point of the company network.

In LAN infrastructure mode, the base is connected to an access point of an external network via either LAN port 1 or 2 via a network cable. The transmission of content by means of Klick&Show Transmitter or Klick&Show App is thus also carried out via this network. The access parameters required for the external access point (SSID, password) are configured via the web menu of the Klick&Show basis. The transmitters receive the necessary connection information to connect to the network through pairing.

LAN Infrastructure Mode: for connecting the base to the company network via LAN

In addition to the wired connection between Klick&Show base and external access point in "LAN infrastructure mode", an additional wired network connection can be provided by means of a remaining LAN port. Another external access point could also be connected here, for example to enable separation of employee and guest networks. Both access points would then be able to enable connected participants to transmit content on an equal footing. When configuring in the web menu of the base, it is possible to specify which external access point is to be used to pair the transmitters, as long as it is connected to one of the LAN ports.

Note on the use of the BYOM function in the Klick&Show K-FX Series:

To conduct BYOM online meetings with KLick&Show K-FX requires that:
– a connection to the Internet can be established from the user's end device,
– a network connection can take place between the user's laptop and the USB conference devices connected to the base

With regard to the individual network modes mentioned above, the following notes must be observed so that BOTH conditions can be fulfilled at the same time:

1) Access Point Mode: A wired network connection must be made in such a way that the user end devices wirelessly connected to it are in the same network address range as the base device and access to the Internet is possible.

2) Wireless Infrastructure Mode: In this operating mode, there is an immediate connection to the corporate network that meets both of the above requirements and enables BYOM.

3) LAN infrastructure mode: In this operating mode, there is an immediate connection to the company network that fulfills both of the above requirements and enables BYOM.

This applies both to the use of transmitters on a K-FX series base and to purely software-based BYOM connections using Klick&Show App, because even when using transmitters, the rear data stream of the USB conference devices always takes place directly to the WLAN of the user's laptop.

10. WebUI

10.1 Welcome to Klick&Show

All members of the Klick&Show The product family (K-FX series, K-40, K-WM) have a uniform, web-based graphical user interface, hereinafter referred to as WebUI (Web User Interface), which can be accessed via browser.

hint:
The WebUI can be accessed in the browser by entering the IP address, which is displayed in the network status bar of the home screen. To do this, open your browser and enter the corresponding IP address in the address bar as shown on the Klick&Show Homescreen.

Depending on whether the internal access point is active and/or wired connections have been established via LAN 1/2, several IP addresses may be displayed.
Each of these addresses allows access to the WebUI.

After successfully entering the address in the browser, the Klick&Show WebUI by displaying the WebUI page"Welcome to Klick&Show„. This part of the WebUI is accessible without password protection and users can:

the version of the Klick&Show Download the app
access the online help.

Integrators or the internal IT department are advised to enter the contact details of their own user helpdesk under "Help & Support". As a factory setting, the contact details ofKindermann by way of example.

10.2 Accessing Administration

In order to Klick&Show system, call the WebUI of the respective Klick&Shows base device via its IP address in the browser, so that the WebUI page "Welcome to Klick&Show".
Now, click on the gear icon in the middle to get to the login page for device administration.
Enter the login password here.

The default password on delivery or after a reset is "admin".

hint:
You can change the admin password or deactivate the password query in the menu item Security Settings. If you forget the password, you must reset the base to factory settings via reset.

11. Administration – Klick & Show configure

11.1 Network settings

Via the WebUI menu item "Network Settings" you can configure one of a total of 3 different operating modes for the wireless network connection on the WebUI page "WLAN Configuration" and the parameters for a wired Ethernet connection on the WebUI page "Ethernet".
The practical use of the 3 operating modes for wireless network connection is described in Chapter 9.2 . The corresponding menu items in the WebUI are explained below.

11.1.1 WLAN Configuration

After selecting the WebUI page WLAN Configuration , you will first get an overview of the set device name, network mode and MAC address:

Click Edit to change the parameters. To do this, make sure in advance that you are connected to theKlick&Show basis.

hint:
Changes to the networkconfiguration can only be made via a wired network connection! When wirelessly connected to the internal Klick&Show Access Point would run the risk that its own connection would be disconnected in the further course of the configuration and that it would no longer be possible to change the parameters. Therefore, a corresponding warning is issued in advance:

WLAN configuration in the Klick&Show WebUI

Step 1: Device Name and SSID Information

In the left pane of the page, you can now select the device name of your Klick&Show Define the base and the WLAN SSID information for a guest or internal network (company/employee/campus network). All 3 pieces of information are then stored in the Klick&Show Homescreen status bar. The device name also appears in the animated banner area of the factory home screen and in the list of available Klick&Shows base devices in the network, e.g. when starting the Klick&Show App for Windows and macOS.

If the Klick&Show In the course of the network configuration, the device name is also the WLAN identifier (SSID)!

hint:
We recommend using a name that speaks for itself as the device name, e.g. based on the room name. The default name is "KlickandShow-xxxx".

Device name and SSID information can only consist of the letters "a-z", "A-Z", digits "0-9" and the characters "-_". National special characters can cause problems with Apple AirPlay, for example.

Regarding the text length for device name and SSIDs, there are 2 conditions:
a) The maximum (theoretical) character length when typing in the WebUI is 25 characters
b) However, all characters of the chain must be representable in one line of the corresponding homescreen status field.
For visual reasons, device names and SSIDs are displayed on a single line, i.e. without line breaks. So it depends on the individual combination of upper/lower case letters, numbers and special characters how many characters the device name and SSID may actually consist of. If you notice a truncation of the text string entered in the WebUI on the homescreen, please choose a shorter device name and SSID or choose a combination of characters that takes up less width.

The SSID information for guest and internal network is plain text information fields that do not affect network configurations.

Step 2: Network Mode

In the right area of the page, the actual network operating mode can now be selected. The 3 operating modes "Access Point", "Wireless Infrastructure" and "LAN Infrastructure" are available as described in Chapter 9.2 . Depending on the mode you set, the associated parameters will change as described below.

a) Access Point Mode:

In this network mode, the integrated access point of a Klick&Show base device, so that Klick&Show transmitters, and subscriber devices directly to the base. In addition, connections via the Ethernet ports and connected infrastructure are possible, but transmitters can only be coupled to the internal access point. Access Point Mode is the factory default mode.
The following options are available:

WiFi Bridging: Here you can choose whether or not you want to allow bridging to either LAN 1 or LAN 2. This can be done with the Klick&Show Access Point connected subscribers can access the network services connected to LAN 1 or LAN2, e.g. Internet access.
Frequency band: Choose between 2.4 or 5 GHz
Canal: Choose a free Wi-Fi channel
Show SSID:
The default setting is "On". If you select "Off", for example for IT security reasons, the Wi-Fi network ID will be hidden, i.e. it will not be displayed on a participant's device when searching for available Wi-Fi networks. However, if you know the SSID, you can manually connect to the Wi-Fi network.
Password: The WLAN password is automatically assigned in the standard configuration and updated at fixed intervals, so the field can remain empty.
If you want to work with your own static password, you have the option of assigning one here.
In this case, the change interval must also be set to "Never"!

Apply the settings by clicking on "OK".

b) Wireless Infrastructure Mode:

In wireless infrastructure mode, the internal WLAN function unit of the Klick&Show Base is operated as a "station" in the "WLAN Client" operating mode (comparable to a subscriber device) and connects the base wirelessly to an existing access point of the company network. The transmission of content by means of Klick&Show Transmitter or Klick&Show App is thus also carried out via the company network. A direct connection to the internal WLAN functional unit of the Klick&Show Basis is therefore no longer possible.
The following options are available:

Select Network SSID (Basic) + Password:
Scan the network environment and select from the list the desired external access point with which the Klick&Show Base unit is to be connected. A reception quality is specified for each WLAN found. Next, enter the appropriate password.
Select Network SSID (Transmitter):
Scan the network environment and select from the list the desired external access point with which the Klick&Show Transmitter are to be connected. A reception quality is specified for each WLAN found. Next, enter the appropriate password.
5 GHz only:
This can be used to restrict the display of found networks to those in the 5GHz band.

A successful connection is indicated by a green tick. Apply the settings by clicking on "OK". The access parameters required for the external access point (SSID, password) are stored in the Klick&Show basis. This provides the transmitters with the connection information necessary for pairing in order to connect to the external network. The external access point for the transmitters can be identical to the external access point of the base – or different. If you want to use separate Wi-Fi networks, you will need to configure them so that one transmitter can communicate with the base.

c) LAN Infrastructure Mode:

In LAN infrastructure mode, the internal WLAN function unit of the Klick&Show Base completely shut down. The base unit is thus connected to the company network exclusively via wired LAN and the transmitters are connected to an external access point in a similar way to the wireless infrastructure mode described above.
The following options are available:

Select Network SSID (Transmitter):
Scan the network environment and select from the list the desired external access point with which the Klick&Show Transmitter are to be connected. A reception quality is specified for each WLAN found. Next, enter the appropriate password.
5 GHz only:
This can be used to restrict the display of found networks to those in the 5GHz band.

hint:
If the desired SSID does not appear in the list of found networks, repeat the scan operation or verify that you have selected the correct frequency range.
After entering the password, please note that the processor responsible for WiFi communication is located within the Klick&Show It takes a certain amount of time to initialize necessary parameters for the changed network mode. If repeated attempts do not result in a successful connection to the external access point, try restarting the Klick&Show Base.

When selecting Wi-Fi, make sure that the displayed level is as high as possible to ensure a stable and high-performance connection.

At the end of a complete change of the network mode, you will be reminded in all 3 cases to re-pair existing transmitters in order to transfer the required communication parameters to the transmitters.

11.1.2 Network – Ethernet

From the Network Settings menu, select > Ethernet.

Hint:
Klick&Show Base units have two RJ-45 LAN interfaces. The LAN ports are separated for IT security reasons and each has its own MAC address, which means that connected LAN networks remain segmented.
Somit can be a Klick&Show base, for example, with an in-house network and a guest network, without establishing a direct connection between the two networks.

IP Settings:

DHCP (Enable): Klick&Show receives its IP address dynamically from a DHCP server on the network.
If DHCP has been enabled, the following items cannot be configured.
DHCP (Disable):Klick&Show is manually assigned a fixed IP address. A static IP can facilitate administration and increase reliability.
IP address: Enter the IP address used by theKlick&Show should be reachable in the network.
Mask: Enter the network filter mask here.
Gateway: Enter the IP address of the gateway here – if necessary.
DNS1: Enter the primary DNS server.
DNS2:Enter secondary DNS server (optional).
MAC: Displays the MAC address of the LAN port. This cannot be changed.

To save the settings you have made, click on "Confirm Settings".

Both LAN ports can be configured separately according to the above pattern and each has its own MAC address.

11.1.3 Authentication according to 802.1X

Optionally, it is possible to configure the Ethernet port individually for each Ethernet port of the Klick&Show Based on a wired authentication, IEEE standard 802.1X will be set up. The IEEE standard 802.1X is a particularly secure method for individual access control to local networks. The standard uses the Extensible Authentication Protocol (EAP) to exchange authentication information. Central authentication and user management is carried out via the RADIUS server (Remote Authentication Dial-In User Service).

Hint:
The wired authentication function according to IEEE standard 802.1X can currently only be used in conjunction with the Klick&Show base unit, but not with the Klick&Show Transmitters. This introduces a Klick&Show system in one of the infrastructure network modes, with the restriction that the Klick&Show transmitter cannot be connected to the RADIUS server of the customer's network. Therefore, in such an environment, it is envisaged that Klick&Show in "access point network mode", which connects the transmitters to the internal access point of Klick&Show and only the Klick&Show base is wired to the customer's network via Ethernet port and authenticated.

Klick&Show currently supports the following EAP authentication types:
• EAP-TLS (Transport Layer Security)
• EAP-TTLS (EAP Tunneled Transport Layer Security)
• PEAP (Protected Extensible Authentication Protocol)

A wizard guides you through entering the required parameters:

Authentication: Selection of EAP-TLS, EAP-TTLS, PEAP and "No authentication"
Domain: Enter the domain listed in the server certificate here
Identity: Enter the "Identity" (e-mail address) associated with the user profile
Password: Enter the password assigned to this user profile here.

For EAP-TLS only, the following section is relevant:
Deploy certificate: Manually deploy client and CA certificates

Upload client certificate (PEM): Provide the client certificate in PEM format here
Upload client certificate key: Provide the certificate key of the client certificate here
Client Certificate Password: Enter the password associated with the client certificate here
Upload CA certificate: Provide the CA certificate here

11.2 Display & Audio

11.2.1 HDMI

On the WebUI "HDMI" page, select the resolution and refresh rate that the Klick&Show base device on the HDMI output. In addition, you can activate a control system based on the CEC protocol.

The Klick&Show The base unit reads the so-called EDID information of the output device (display, projector) in advance. The EDID is a data structure that displays of a connected signal source use to describe their capabilities.
The triggers listed in the list selection field of the WebUI are based on the possibilities of the connected output device: For example, if no 4K-compatible output device is connected, no 4K resolution is offered for selection.

In the Auto setting, Klick&Show select the EDID information of the display device and select the best available setting. If you are not satisfied with the image quality, you can choose a suitable resolution from the list of available resolutions.

For K-FX Plus, the two existing HDMI outputs can be configured separately from each other, referred to as "MAIN" (main output / primary output) and "SUB" (secondary output).

hint:
If the newly selected resolution cannot be displayed, the previously active resolution is restored after about 15 seconds.

All Klick&Show Basic devices support resolutions up to a maximum of 4K/60Hz on the HDMI (main) output, while the SUB output of K-FX Plus supports a maximum of 1920×1080/60Hz.

CEC

CEC is the Consumer Electronics Control (protocol) standardized by the HDMI organization. Klick&Show Base devices support the instruction sets for switching on and off.
If your display device (e.g., display) is also compatible, you can turn the display or display on and off. Klick&Show Basis via this.

With the "Control the display via CEC (by Klick&Show)", the display reacts to switching on and off or waking up the Klick&Show for example, when plugging a transmitter into a laptop or starting the Klick&Show App for Windows and macOS.

With the "Klick&Show controlled by CEC (through the display)", the display switches the Klick&Show Base on or off synchronously to the operation of the display.

Both options can also be activated at the same time.

Hint:
Please check if your display or projector supports the CEC protocol. In some cases, only certain inputs on the device support CEC.
Information about this can be found in the operating manual of your display device.

11.2.2 Audio

On the WebUI "Audio" page, the type of audio output and volume can be adjusted. Audio output can be done in 4 ways:

only via the digital HDMI output
only via the analog 3.5mm jack output
simultaneously via HDMI and the 3.5mm jack output
via USB
(only for K-FX series devices for BYOM online meetings)

In the case of basic devices of the Klick&Show K-FX Series, audio is always output via USB to a connected USB conference device, e.g. a USB video soundbar, a USB speakerphone or an integrated USB audio room solution. In BYOM mode, simultaneous audio output via USB and other audio signal paths (HDMI, 3.5mm jack output) is not possible to ensure that the echo cancellation required for online meetings is not affected in the USB signal path.

The maximum playback volume can also be limited by adjusting the volume.

Hint:
Due to the internal switchable USB hub on the basic K-FX Plus model, the option to output audio via "USB" is only visible when the USB devices are actually accessed. To do this, switch the USB Hub Switching to the "Wireless" operating mode, as described in Chapter 11.8.1 .

11.2.3 Home Screen

On the WebUI page "Home Screen", various basic settings can be made to customize the display of information both before and during a transfer of user content, as follows:

View the code and network SSID during transmission (Floating Window)
When this option is selected, the Klick&Show displays a small, semi-transparent window at the top of the screen when transferring user content. This means that the network access parameters (guest SSID, PIN) remain permanently visible to subsequent participants, for example to establish a connection via Klick&Show app or mobile device.
At the beginning of the transfer, briefly display the user name
When this option is selected, the Klick&Show briefly enter a subscriber's username at the start of a new broadcast, depending on the type of transmission.
– When connected to a transmitter, a transmitter identifier is displayed
– When using the Klick&Show app, the name of the laptop owner is displayed
Hide connection information on the home screen
When this option is selected, all connection information is hidden in the network status bar of the factory home screen (SSIDs, PIN, IP addresses). This can be useful for security reasons if the administrator does not want a manual connection to the network and thus no use of Klick&Show app or mobile devices, but an exclusive use of the Klick&Show Transmitter.
Hide QR code for quick access
When this option is selected, the QR code is hidden in the factory home screen. This can be useful for security reasons if the administrator does not want a manual quick connection to the network through mobile devices.
Hide Clock
When this option is selected, the date and time are hidden in the status bar of the factory home screen.
This can be useful in exceptional cases, if the Klick&Show Base device is permanently not connected to a network and therefore there is no connection to a time server, which can result in an incorrect time specification.
Klick&Show App URL
The animated Klick&Show Homescreen factory-displayed link/URL to download the Klick/Show app ("KlickandShow.com/client") can be customized if an administrator wishes to change the Klick&Show To provide drivers in a different location (e.g. for reasons of IT security in the internal company network) and to display this in the home screen accordingly for the users.
Setting the Switching Interval for the Home Screen
This option can be used to set the time interval after which the individual pages of an animated home screen should change. You can choose from 5 seconds to 30 seconds. The specification affects both the factory animated homescreen and customer-specific animated homescreens.

11.2.4 Customizing the Homescreen

The WebUI page "Customize Homescreen" provides various ways to use a customized homescreen:

Set background image
By clicking on the "+" symbol, either a single or up to 3 wallpapers can be loaded, which then replace the factory home screen. Please note the notes on compatible formats and image sizes in the WebUI of the respective base device.
If more than one image is loaded, several images are automatically merged into an animated home screen, the switching interval of which can be set on the WebUI page "Start screen".
A loaded image can be deleted by clicking on the garbage can icon .

After loading a customer-specific background, it is initially stored by the factory Klick&Show network status bar at the top of the screen, so that manual connections can also be made using Klick&Show app or mobile devices. A customer-specific background should therefore be designed in such a way that relevant image elements are not positioned in this area, but this area remains provided with a neutral color.

If the superposition is caused by the factory Klick&Show Network status bar not desired, for example if only Klick&Show transmitter, the custom homescreen can be customized with two additional options, which can be used either individually or in combination:

– Hide connection information on the home screen
If you select this option, only the left part of the network status bar will be hidden. The QR code remains visible to enable connection with mobile devices (e.g. for Airplay connections).

– Hide QR code for quick access
If you select this option, only the QR code within the status bar will be hidden.

If both options are selected at the same time, the network status bar is completely hidden.
Custom Logo
By clicking on the "+" symbol, a single logo graphic can be loaded, which is then displayed in the designated area on the right of the network status bar. Please note the notes on compatible formats and image sizes in the WebUI of the respective base device.

hint: Please note that a logo cannot be used at the same time as a loaded custom background!
A loaded image can be deleted by clicking on the garbage can icon .
Custom font color
By selecting this option, a custom font color can be selected for the factory network status bar, so that the color can be matched to match the logo or a custom background.

11.2.5 Digital Signage

Thanks to the integrated digital signage function, you can use the display of your Klick&Show system even when no meetings are taking place. Depending on the day and time, any web content can be loaded and the existing display can be used to display information.
The web content displayed can be any existing website (e.g. a public page of your company) or a website specially designed for this purpose (e.g. an internal information page for employees or guests of the company).
The accessed web content is then displayed by an internal web browser of the Klick&Show basis.
The WebUI Digital Signage page provides the following options:

Enable
This switch activates or deactivates the desired use of the digital signage function.
Activation occurs after an adjustable period of time, when the Klick&Show system remains unused, which can be set in the menu item "System Configuration" on the WebUI page "Auto Stand-by". In the line "Note:..." a direct link to it is indicated. The "unused" state occurs in Klick&Show if there is no longer an active subscriber connection via either transmitter, Klick&Show App or one of the native protocols.
Url
In this input line, the hyperlink to the desired web address can be stored, which is displayed when the digital signage function is called up by the internal browser of the Klick&Show basis.
Factory preset is https://www.klickandshow.com/en/.
Setting the time range
Here you can set the start and end times within which one display per day should be made.

To do this, click anywhere in the setting field and then select the desired start and end time in the white pop-up window. Complete your entry by clicking "OK" button.
Minimize the network status bar on the home screen
When this option is selected, the Klick&Show when viewing web content, the network access parameters (guest SSID, PIN) are permanently visible in the upper left corner, for example, in order to enable subsequent participants to connect via Klick&Show app or mobile device.
Only on these days
Select here on which days of the week the digital signage function should be activated.
Confirm settings
Any changes made to the WebUI Digital Signage page will take effect only after you click the Confirm Settings button.

For testing purposes, the digital signage mode can also be terminated by briefly pressing the "Power Button" on the base.

Hint:
When accessing web content for the first time, data protection settings are often requested, for example to agree to the use of cookies. Such queries require a way to enter a confirmation.
If the Klick&Show Used in conjunction with an interactive display, inputs can be made directly on the display. Alternatively, a commercially available PC mouse with the Klick&Show base, whereupon a cursor is displayed in the main display.

11.2.6 Dual Display (K-FX Plus)

On the WebUI "Dual Display" page (only available for K-FX Plus), the type of screen output can be configured by 2 HDMI main display devices. There are 3 output modes to choose from:

Mode: Mirroring
In Mirror mode, the primary output (MAIN) and secondary output (SUB) always show the same (mirrored) content.
This type of output can be advantageous if only 1 main display content is required, but it is to be output simultaneously via 2 display devices, e.g. via a large format display and additionally via a projector.
Mode: 4+1
In "4+1" mode, the primary output (MAIN) and the secondary output (SUB) can display different content depending on the number of simultaneous user content.
The content of the first participant is output in full screen on SUB (1), a second content then in full screen on MAIN.
Further participant content is then automatically added to MAIN (4) in split image view until a maximum of 4 contents are visible there.
Mode: 1+4
In "1+4" mode, the primary output (MAIN) and the secondary output (SUB) can display different content, depending on the number of simultaneous user contents.
The content of the first participant is output in full screen on MAIN (1), a second content then in full screen on SUB.
Further participant content is then automatically added to SUB (4) in split image view until a maximum of 4 contents are visible there.

11.2.7 Native Protocol (K-FX Plus)

On the WebUI page "Native Protocol" (only available for K-FX Plus), the type of image transmission can be configured in detail using native protocols (Airplay, Miracast, Google Cast). Settings made on this page correspond to corresponding settings of the WebUI "Security Level" page, which is available for all Klick&Show basic units (including K-FX, K-40 and K-WM).
Depending on the type of native protocol, the following settings are available:

Airplay
The "Activate Airplay" switch can be used to activate or deactivate the desired use of the Airplay protocol.
The list selection field can be used to specify the desired maximum resolution that an iOS or macOS device can use during an Airplay broadcast. Klick&Show K-FX Plus.
A higher resolution ensures higher image sharpness, but can result in uneven playback or latencies in moving content.
(Note: For the Klick&Show Base devices K-FX, K-40 and K-WM, the Airplay resolution is fixed to the value "HIGH 1920×1080".)
Miracast
The switch "Activate Miracast" can be used to activate or deactivate the desired use of the Miracast protocol.
The "Enable MS-MICE" switch can also be used to enable or disable the use of the "Miracast over Infrastructure Connection Establishment Protocol". In this case, when the Klick&Show With the company network, a connection is established via the existing network infrastructure instead of the otherwise carried out WiFi direct connection (peer-2-peer).
Hint: For the Klick&Show For the basic devices K-FX, K-40 and K-WM, compatibility with MS-MICE is permanently activated (i.e. cannot be deactivated manually).
Google Cast
The "Activate Google Cast" switch can be used to activate or deactivate the desired use of the Google Cast protocol.
Please note the note on the WebUI page that the protocol only allows transmission if the set time on the end device and the Klick&Show base not deviate from each other by more than 24 hours.

11.3 Moderation Menu

In the menu item "Moderation menu" all settings that concern interactive collaboration are summarized. In order to be able to use these possibilities as intended, it is necessary to Klick&Show can be used in combination with an interactive display.

11.3.1 Sidebar Settings

The Klick&Show Sidebar gives instructors and presenters quick access to a variety of collaboration tools, including attendee moderation, whiteboarding app, and annotation app. The specific use of these tools is described in Chapter 7 .
Below you will find out how to configure the view or access to the sidebar, which will then appear on the home screen and when transferring user content on the right edge of the screen.

After activating the sidebar, access is via the arrow on the right edge of the screen

Configuration options for view and access to the sidebar in the WebUI

Hide menu completely (no access to whiteboard & annotation)
The overlaid arrow of the sidebar on the right edge of the main screen remains completely hidden, so that no access to the tools is possible.
Small menu
A gray arrow appears on the right side of the display. By tapping a menu opens and allows access to the whiteboard or annotation app.

Large menu
If you select this setting, an enlarged status bar will be displayed, on which you will also see Klick&Show connected user devices can be displayed as a thumbnail image and selected by the instructor by tapping. If a participant is using a transmitter or the Klick&Show app for Windows or macOS, so the sidebar shows a live preview, in other cases an icon.)

11.3.2 Splitscreen Layout

Klick&Show allows the simultaneous display of up to 4 participant content on one output device in the form of a split image view. On the WebUI page "Splitscreen Layout" you can define presets for the maximum number as well as the size and arrangement of the displayed content. All layout options aim to make the best possible use of the available screen space.

When adjusting the preferences, you should be aware of how a change can affect the course of a meeting.
For example, if you allow only 1 participant content and thus deactivate the split image view, there will be an immediate switch between participant content, which can make a meeting very intuitive and dynamic.
A split image view can make a meeting more productive in such cases if 2 or more pieces of content are to be compared frequently.

Maximum number of devices displayed on the main screen
Use this drop-down list box to define the maximum number of content that can be displayed at the same time. In the case of simultaneous use of 2, 3 or 4 contents, the layout is then defined in the following step.
In the event that only 1 content is defined, there is no longer a split image display and instead there is an immediate switch as soon as another participant transmits a new content.
Splitscreen layout for 4/3/2 devices
By selecting the layout icons, you can choose the size and arrangement of the content. Most layouts display all content in the same size, which is advantageous in practical meetings when all content typically has the same "priority" in the comparative display. However, some layouts for 4 devices offer the possibility to display the source displayed first larger than subsequent content, which is advantageous if a certain content should remain particularly recognizable.

11.4 System Configuration

11.4.1 Transmitter (K-FX Series, K-40)

The WebUI page "Transmitters" offers various options for managing Klick&Show Transmitters.
The "Connected" tab shows a status overview of all transmitters currently connected to the base device and Klick&Show App software clients.

Here you can see the type, Mac address, serial number, software version, as well as the device status and last activity. The "Operate" function can be used by the administrator to manually start or stop the transfer for test purposes.

Hint:
Connections via the native protocols AirPlay, Miracast and Google Cast do not support this type of management and are therefore not displayed.

The "Paired" tab shows all transmitters that have ever been connected to this Klick&Show base device.
The name of the HDMI and USB-C transmitters can be changed at this point, so that a room assignment can be made, for example.
The "Remove" button (garbage can) can be used to select and decouple (separate) individual or all transmitters. Before the next use of a transmitter on this or another base, the transmitters must then be taught again.
In this way, abusive transmissions of stolen transmitters can be prevented.

11.4.2 Date and time

The WebUI Date & Time page, arranged in two tabs, offers various ways to set the time and time zone.
Under the "Date & Time" tab, the display format can be selected and the time setting can be automatically obtained from a time server from the Internet or assigned manually (e.g. if there is no connection between the base and the Internet).
Optionally, the preset time server on the Internet, e.g. with a local server, can also be replaced.
Under the "Time zone" tab, the time zone can be selected accordingly.

Hint:
In the factory setting, the Klick&Show Basic access to a time server, otherwise no time and date information is displayed on the home screen.

11.4.3 Car stand-by

The WebUI page "Auto Stand-by" allows you to configure a period of time after which the operating state of the Klick&Show base switches to power saving mode. Auto Stand-by sets the Klick&Show Base automatically enters energy saving mode if there is no subscriber connection or use of the base device within the selected time.

In stand-by, the LED ring on the top of the base flashes and the HDMI output is switched off. However, network connections remain active. Once a subscriber device is connected to the Klick&Show base device is connected, the power saving mode is exited.
Waking up the base can be done by a user connecting an existing transmitter to his laptop or, in the case of software-based use, by using the Klick&Show App starts and connects to the base after the network scan has been completed.
Pressing the POWER button on the front or side of the device or entering it on the connected touchscreen also ends the energy saving mode.

Hint:
The setting of the auto-stand-by time also corresponds to the use of the digital signage function (see chapter 11.2.5). If the digital signage function is used, the base device does not activate the energy saving mode after the auto stand-by period has elapsed, but instead displays the digital signage content.

11.4.4 Language

On the WebUI Language page, you can select the desired language from Klick&Show set independently for the user level (Klick&Show Homescreen) or for the administrator level (WebUI).

11.4.5 Resetting

The base device can be reset to factory settings via the WebUI "Reset" page. To do this, select the "Confirm settings" button and confirm the following security prompt. Alternatively, you can use the Klick&Show Base device can also be reset using the reset button on the back of the device.

11.4.6 Configuration File

The WebUI Configuration File page provides two tabs for backing up and restoring a Klick&Show System configuration.
Under the tab "Download configuration file" you can save the current system configuration as a local file (Config.dat).

Under the tab "Upload configuration file" you can then import it again (e.g. after a reset) or click on another one Klick&Show base device, so that the configuration effort is minimized.

11.4.7 Device Control

The WebUI page "Device Control" can be used to provide various ways to communicate between Klick&Show with external devices via RS232 or Telnet.
The RS232 interface works bi-directionally, which allows the Klick&Show can be remotely controlled on the one hand, e.g. by an external AV control system, but on the other hand, the Klick&Show system to automatically turn an external device (e.g. a projector) on or off.
For security reasons, they have RS232 and Telenet activated or deactivated separately from each other.
In addition to the device control options described here, HDMI CEC should also be mentioned, which is Klick&Show supported and divided into chapters

Hint:
In addition to the possibilities of device control via RS232 and Telnet described here, Klick&Show also HDMI CEC (see Chapter 11.2.1).

RS232

Remote control of the Klick&Show Base by RS232:
For this operating mode, configure the selection item "Function of the RS232 interface (How to use RS232 port)" to "Klick&Show remote control ". Klick&Show reacts to incoming control commands from an external device. The control commands are identical to the Telnet commands.
You can adopt the necessary communication parameters (baud rate, etc.) or adapt them to the capabilities of the AV control.

Remote control of external devices by RS232:
For this operating mode, configure the selection item "Function of the RS232 interface (How to use RS232 port)" to "Klick&Show Control other devices" and adapt the communication parameters to the technical requirements specified by the device to be controlled. Klick&Show is now able to send commands to an external device – depending on the current operating state of the Klick&Show Base.
With the help of this function, an automated switching on/off of a display device (e.g. projector) at the beginning and end of a meeting can be realized, even if the display device does not support HDMI CEC protocol, for example.
The RS232 commands, syntax and communication parameters compatible for your specific display device can be found in the user manual of your display device.

Commands can be stored for the following operating states (table column "Action"):

Turn on
(as soon as the power supply is Klick&Show was produced)
Stand-by is activated
(if Klick&Show enters sleep mode after all participant connections are terminated at the end of a meeting.)
Stand-by is deactivated
(if Klick&Show wakes up from sleep mode and returns to normal operation.)

For each command, a delay time in milliseconds can be entered separately, which means that the actual sending of the command takes place with a delay after the respective Klick&Show operating condition.
Using the checkboxes in column "ON", the stored command can be set active or inactive. In the table column "Command" the actual commands must be entered in ASCII.

Telnet Control

Here the control can be activated or deactivated via Telnet.
The control commands can be found here.

11.4.8 GPI Definition (K-FX Plus)

The WebUI page "GPI Definition" offers a selection of different functions that can be assigned to the so-called "GPI contacts" on the back of the K-FX Plus base device.
The GPI (General Purpose Interface) contacts provide a way to (remotely) control a K-FX Plus system using external buttons. For this purpose, K-FX Plus 2 offers separate GPI interfaces, denoted by GPI 1 and GPI 2. A potential-free probe is connected to the corresponding GPI contact and the marked, shared ground contact. If a connected potential-free button is pressed, this creates an electrical connection (short circuit) between GPI 1 or GPI 2 and ground, which triggers the appropriately configured function.

For configuring the GPI 1 and GPI 2 interfaces, K-FX Plus offers the following functions:

USB Hub Switching
The USB Hub Switching (also called Dual-UCC function ) allows existing USB devices to be used twice: either for wireless BYOM meetings, connected to K-FX Plus – or for traditional UCC meetings, connected to a stationary PC. With USB hub switching, the USB ports marked as "USB Devices" on the back are either manually assigned to a stationary PC via "USB3.0 Host" output or used for BYOM meetings via K-FX Plus. The repeated operation of a GPI contact switches between the two operating modes "USB-B" and "Wireless". A description of USB Hub switching can be found in Chapter 11.8.1.
Camera Switching
With the dual-cam function, you can offer remote online participants different perspectives by using two USB cameras alternately for BYOM meetings wirelessly on your laptop. The repeated activation of a GPI contact switches between two cameras.
HDMI switching
Content from wired HDMI sources, such as a stationary computer or document camera, can be presented on the main local display via the built-in 4K-compatible HDMI input. When an HDMI source is reconnected, it is immediately automatically displayed (auto-switching). By repeatedly pressing a GPI contact, the display of the HDMI source can also be manually activated or deactivated.

11.4.9 Key Definition (K-FX Plus)

The WebUI button definition page offers a selection of different functions that are similar to the two function buttons of the Klick&Show 4K transmitter in combination with a K-FX Plus base unit.
If a 4K transmitter is used in combination with a K-FX or K-40 system, the function assignment is not configurable, but instead fixed with the functions "Full Screen" and "Freeze".
The two function buttons provide a way for the user to trigger additional functions during a meeting. If one of the function buttons on the transmitter is pressed, the corresponding function is triggered.

To configure the transmitter function keys 1 ("-") and 2 ("="), K-FX Plus offers the following functions:

Full screen
Repeatedly pressing the function button on the 4K transmitter allows you to switch between split and full-screen display (from split mode).
This function corresponds to the corresponding button in the Klick&Show App.
Freeze
When the function button on the 4K transmitter is pressed, the live broadcast is paused for a short time and resumed when it is pressed again. The participant content remains visible, but is frozen.
In addition, the network status bar with access parameters is displayed at the top of the screen. This will allow participants who use either Klick&Show app or native protocols, help is offered, and the parameters required for a connection, such as device name and PIN, are briefly displayed.
This function corresponds to the corresponding button in the Klick&Show App.
HDMI switching
Content from wired HDMI sources, such as a stationary computer or document camera, can be presented on the main local display via the built-in 4K-compatible HDMI input. When an HDMI source is reconnected, it is immediately automatically displayed (auto-switching). By repeatedly pressing the function button on the 4K transmitter, the display of the HDMI source can also be manually activated or deactivated.
Share local content
K-FX Plus lets you receive a mirrored live view of the full main screen to share shared local content even with remote people on a BYOM call. When this function is triggered, the Klick&Show app creates a browser window on the user's laptop, which displays the combined live content of all local participants (including possible annotations) of the Klick&Show main display. This window can then be presented within your UC application (e.g. Teams, Zoom) as shared content as part of a BYOM meeting.
This function corresponds to the corresponding button in the Klick&Show App.
Hint: Since the feature is only intended for use during a BYOM meeting, it can only be triggered when a UC application is running on the user's laptop and a USB camera connected to K-FX Plus is accessed. In other cases, pressing a button has no effect.
Camera Switching
With the dual-cam function, you can offer remote online participants different perspectives by using two USB cameras alternately for BYOM meetings wirelessly on your laptop. Repeatedly pressing a function button on the 4K transmitter switches between two cameras.
USB Hub Switching
The USB Hub Switching (also called Dual-UCC function ) allows existing USB devices to be used twice: either for wireless BYOM meetings, connected to K-FX Plus – or for traditional UCC meetings, connected to a stationary PC. With USB hub switching, the USB ports marked as "USB Devices" on the back are either manually assigned to a stationary PC via "USB3.0 Host" output or used for BYOM meetings via K-FX Plus. Repeatedly pressing a function button on the 4K transmitter switches between the two operating modes "USB-B" and "Wireless". A description of USB Hub switching can be found in Chapter 11.8.1.

11.4.10 Restart

The WebUI "Restart" page provides the ability to set up automatic restarts of the WebUI for certain days of the week and a specific time. Klick&Show system.
Defined reboots can improve the operational reliability/stability of the system in the context of daily use.
To do this, activate the schedule, select the desired working days and time and confirm the configuration with the "Submit" button. The "Reboot now" button triggers an immediate restart.

11.5 Security settings

IT security is important in commercial sectors. Klick&Show offers a high level of data security through secure WiFi transmission based on AES WPA2/3 PSK authentication. As a further protective measure, the captured laptop data stream is additionally encrypted with a second stage of up to 256/1024 bits before the actual data is transmitted wirelessly.
Via the WebUI menu item "Security Settings" you can configure security-relevant parameters individually.

11.5.1 Security Level

On the WebUI Security levels page, you can choose between two predefined or a custom security level for Klick&Show choose. The "Custom" security level allows you to select the individual security features individually according to your needs. Security features 1 and 3 are enabled in each level and cannot be disabled. Security level 2 is activated as a factory setting.

Dynamic Code

The code (PIN) secures the use of Klick&Show against unauthorized use. Depending on the network configuration, the PIN is also the Wi-Fi password (in access point mode) or is only used to protect against interference by outsiders, e.g. due to accidental connection.
Changing the code regularly prevents a previous user from being able to present even after leaving the room.

The code remains unchanged as long as a device with the Klick&Show . After the last device disconnects, the set timer expires. Fifteen seconds before expiration, a warning message is sent that the code will change shortly. The timer can be set to different interval times:

5 / 30 minutes
1 / 2 / 4 / 24 hours
Never
(This setting requires you to select the security level "Custom" and then deselect the Dynamic Code checkbox)

hint:
If you Klick&Show in Access Point Mode and select "Never", you must use the Wi-Fi Password input.

tip:
If the password timer is not displayed, at least one device is still connected. Mobile devices can also maintain a Wi-Fi connection in the background and prevent automatic password changes and the STANDBY function!
If the code changes, it will only affect all manual Wi-Fi connections. Transmitters must be not be newly paired with the base device.

Password change deletes the temporary memory

The code remains unchanged as long as at least one device is connected to the Klick&Show is connected. After the last device disconnects, the set timer expires. Subsequently, depending on the setting made, the temporary memory of the Klick&Show Base securely erased. The following settings can be made:

Never (= requires the individual configuration of the security levels)
User decides (a corresponding window appears on the display, after 100 seconds without input the data is automatically deleted)
Always

Encryption of data: Proprietary

The user content is secured with proprietary encryption (1st encryption level) before the actual wireless transmission to the base device. In addition, a further level of data encryption is provided during the subsequent wireless communication between transmitters or software clients for Klick&Show Basis by WPA2/3 (2nd encryption level).

Encrypt video/audio data with AES-256 bit + RSA-1024 bit (screen sharing)

The user content is secured with a particularly secure AES-256 bit + RSA-1024 bit encryption (1st encryption level) before the actual wireless transmission to the base device. In addition, a further level of data encryption is provided during the subsequent wireless communication between transmitters or software clients for Klick&Show Base by means of WPA2/3 (2nd encryption level).

11.5.2 Admin Password

The admin password protects access to the administration menu.

The default password in the delivery state and after a reset is "admin".

Please change the password to a secure one when commissioning.
However, you also have the option of disabling password prompting for the administrator menu. To do this, check the box next to "Do not use a password".

11.5.3 Code

Define whether the code (PIN) should be 4 digits (with four leading zeros) or 8 digits.

11.6 Update Firmware

Kindermann provides new firmware updates for Klick&Show Devices ready. These are used to provide new functions, eliminate possible bugs, and increase security and system stability. It is recommended to always use the latest version of a firmware in order to benefit from product improvements.

A new firmware can be used for Klick&Show can be installed in 5 different ways:

Update via WebUI Upload
Automatically update the OTA function via WebUI
Update the OTA function manually via WebUI
Update manually using USB fascist drive
Through central administration via Klick&Show ManageTool

hint:
In the case of an OTA (Over-the-Air) update, the central Klick&Show update server (hosted in Germany) obtained a "differential" update via the Internet. A differential update does not contain a full update, but only adds changes to the software code compared to the existing version.
In all other cases, a full update will be installed.

The file for a full firmware update can be loaded from http://www.klickandshow.com :

Download Firmware K-FX Plus

Download Firmware K-FX

DOWNLOAD FIRMWARE K-40

DOWNLOAD FIRMWARE K-WM

The provided update files are packed as an archive and must first be unzipped before actual use.

hint:
When an update is installed, only the base itself is initially updated. Please remember to update any transmitters that may be available in a subsequent second step, as described in Chapter 5.9 Pairing Transmitters .

11.6.1 Update Firmware (WebUI)

On the WebUI page "Update firmware" you have the possibility to update a firmware according to the above update options 1. to 3., whose setting options and operation are enabled via WebUI.
If, in certain cases, access to the WebUI of a base device is not possible, the particularly simple option is to manually update via USB Flash Drive, as written in chapter 11.6.2 .

1. Update via WebUI Upload

For a manual update via WebUI Upload: Unzip and save the previously loaded "update.img" file to any directory on your computer. Click on "Select firmware" to locate and select the "update.img" file on your computer. Start the update process by clicking the "Start Upload" button.

Attention:
Wduring the update, the device must not be switched off or disconnected from power. There is a risk that your device will become unusable.

The update file is now first checked for compatibility and integrity and uploaded to the memory of the base device. The progress of the loading process is indicated by a pop-up window in the browser.
Note: If there has been no update for a long time, updating from previous firmware versions may result in an inaccurate progress bar. In any case, please wait several minutes before taking the next step.

Once the file has been fully loaded into the base, the actual update process takes place afterwards.
That Klick&Show The base device automatically reboots and now shows the update status on the main display connected via HDMI.
After a new start, the update process is complete and Klick&Show displays the home screen again in the usual way.

2nd / 3rd update via WebUI OTA function

Alternatively, you can also update the firmware via the WebUI via OTA (Over the Air). To do this, the Klick&Show base device can communicate with the update server on the Internet. This feature is factory-enabled. The base automatically checks daily between 0 and 7 a.m. whether an update is available on the update server, which is then downloaded and installed independently.
In addition, you can also manually initiate the search for an OTA update. The update server is located at a location in Germany.

11.6.2 Update Firmware (USB Flash Drive)

11.7 Other settings

11.7.1 Creating USB Tokens Automatically

In addition to the use of Klick&Show transmitters and native protocols, users can also use the Klick&Show App to transfer content from laptop to main display. The Klick&Show App can be loaded from www.klickandshow.com/client , for example, or from the internal WebUI of the base devices.
Another way to conveniently deploy the Klick&Show The app for the people in the meeting room is a so-called "USB token" (also called a "launcher"). This refers to a USB storage medium that contains a copy of the Klick&Show app.

The WebUI page "Automatically create USB tokens" supports you in creating such a storage device. If the function is activated, every USB data carrier connected to the base unit and writable is automatically recognized as a USB token and connected to the Klick&Show app. This function is disabled at the factory.

The progress of the copying process is shown on the main display in a notification window:

After the copying process is complete, you can remove the USB storage device from the Klick&Show Disconnect the base unit.

11.7.2 Support

On the WebUI "Support" page, the email address and phone number of your in-house helpdesk or a service provider can be entered. This information is then displayed on the WebUI home page "Welcome to Klick&Show", which is available for users of Klick&Show is also accessible without an admin password.
In the factory setting, the support information from Kindermann registered.

11.7.3 Developer Tools

The WebUI page serves as a tool for analyzing possible errors. It offers the possibility to retrieve a log file in which past processes and system states are logged and on the basis of which further problem analysis is possible.
Use these tools only when prompted and according to the instructions of a service technician. The log file is encrypted and does not contain any data that can be used by users or administrators.

11.8 UCC Device Manager (K-FX Series)

The WebUI menu item "UCC Device Manager" summarizes all functions that allow the configuration and use of Klick&Show in the context of online meetings (also called UCC meetings, Unified Communications & Collaboration).

11.8.1 USB Hub Switching (K-FX Plus)

Klick&Show K-FX Plus allows existing USB devices to be used in 2 ways: either for wireless BYOM meetings, connected to K-FX Plus – or for traditional UCC meetings, connected to an external stationary PC. Due to this dual benefit, the function is used in marketing communications by Klick&Show also referred to as the "Dual UCC function".
From a technical point of view, K-FX Plus includes a switchable internal USB hub for connecting the USB devices required for UCC meetings (e.g. USB cameras, USB audio device), as well as an additional USB-B port called USB3.0 HOST for external transmission of the signals, as shown below.

A switchable USB hub enables dual UCC function on K-FX Plus

With the help of the dual-UCC function, a possibly already before the introduction of Klick&Show K-FX Plus existing stationary PC in the meeting room (on which all UC applications relevant to online meetings are directly installed, such as Teams, Zoom, etc.) – and K-FX Plus can also be used to host online meetings wirelessly according to the BYOM principle from your own laptop.

In this context, the WebUI page "USB Hub Switching" allows the basic configuration of the Dual UCC function and determines whether the later switching of the two operating modes (external USB-B or wireless use) in real online meetings should be either manual or automatic. The following options are available:

Automatic:
In the "Automatic (Auto)" setting, the dual-UCC function (technically the internal USB hub) is automatically switched according to the following principle:
–Is that Klick&Show K-FX Plus base device is not in use (i.e. no wireless meeting is taking place), so the USB hub remains in the "USB-B" setting, which means that the USB devices connected to the hub are switched through to an external stationary PC via the USB 3.0 HOST port in order to make them available for traditional online meetings.
- When a wireless meeting begins with K-FX Plus, the USB hub switches to Wireless mode so that USB devices connected to the hub can be used by K-FX Plus for BYOM online meetings and can be wirelessly deployed to a user's laptop.
USB-B:
In the "USB-B" setting, the USB hub remains permanently in "USB-B" mode, which means that the USB devices connected to the hub are switched through to an external stationary PC via the USB-3.0 HOST port for use in traditional online meetings.
Wireless:
In the Wireless setting, the USB hub will remain in Wireless mode at all times, so that USB devices connected to the hub can be used by K-FX Plus for online meetings using the BYOM principle and can be provisioned wirelessly to a user's laptop.

Manual switching of the dual-UCC function (of the USB hub)

In all 3 settings above, the actual current operating mode can be overridden in various ways by the user and/or administrator. The selection criterion for which type of switching makes sense in your case can be how often the dual UCC function is to be used – in other words, how often either modern BYOM meetings or more traditional online meetings are carried out alternatively in practical meetings. For example, if many people in the company have been used to conducting traditional online meetings for a long time, such people can continue to work even after a company-wide rollout of K-FX Plus. In other cases, employees can benefit from modern, wireless BYOM meetings.
Depending on the expected frequency of use of the dual UCC function, it may make sense to provide some type of manual switching, where either a single user can make their own desired setting – or this is done by another trained person before a new meeting, such as an administrator.

The following options are available for manual switching of the dual-UCC function (of the USB hub):

4K Transmitter (Function Keys)
The function keys of the Klick&Show 4K transmitters can be assigned various options according to customer requirements, as described in chapter 11.4.9 Button definition .
If one of the function keys is assigned the "USB Hub Switching" function, this enables the switching by any user of Klick&Show. This is beneficial if experienced users want to switch between traditional online meetings as well as BYOM meetings frequently.
"USB SWITCH" button, on the side of the K-FX Plus base unit
The USB SWITCH button on the side allows immediate switching of operating modes. Since the base device is usually installed in a comparatively inaccessible place, this type of switching is more suitable for a smaller, correspondingly informed group of people.
To avoid accidental actuation when touching the button, the USB SWITCH button is disabled in its factory state and can be activated by removing the check mark in the selection box on the WebUI "USB Hub Switching" page.
"GPI" interface, on the back of the K-FX Plus base unit
The contacts of the GPI interface can be assigned to various customer-specific options, as described in chapter 11.4.8 of the GPI definition .
If one of the contacts is assigned the "USB Hub Switching" function, this enables switching, for example, by means of an external button, which can either be arranged accessible to all people – or rather to a limited group of people, depending on the desired objective.
Using the WebUI page "USB Hub Switching"
Manual switching can be carried out by an administrator, either as part of a device test or for rather rare switching of the "USB-B" and "Wireless" operating modes.

Status display on the home screen

The current operating mode of the USB Hub Switching (i.e. the position of the switchable hub) is displayed in the K-FX Plus home screen in the form of a modified icon:

USB Hub Switching Status in Homescreen:
Left: "USB-B" mode,
Middle: "Wireless" mode,
Right: "Wireless" (USB devices in use)

11.8.2 USB Camera (K-FX Series)

The USB camera menu can be used to check the function of the connected USB video device (e.g. integrated camera of a USB video bar or separate USB camera) and to check the basic compatibility with Klick&Show K-FX Series base devices for use in BYOM online meetings.

Only K-FX Plus has the additional "UCC Device Scan" button on this WebUI page, which must be pressed once at the beginning of your tests to ensure that K-FX Plus now uses the devices connected to the switchable USB Hub "USB Devices" for BYOM operation and not for USB3.0 HOST sharing, as described in the previous chapter 11.8.1 USB Hub Switching .

If you have connected several USB devices, select the USB device to be tested in the device list. Note that depending on the type used Klick&Show Basic and third-party devices may take a few seconds to activate before the preview image appears. The preview only retrieves a video stream with reduced preview image resolution from the connected USB camera device.

If multiple USB devices are connected Klick&Show base device, is only Klick&Show K-FX Plus is also able to use and switch these in later conference operation. This is called the dual-cam function . Other Klick&Show Base devices (K-FX) can only use 1 USB camera device preset in the WebUI.

With K-FX Plus' dual-cam function, you can offer remote online participants different perspectives by using two USB cameras alternately for BYOM meetings wirelessly on your laptop. To use and switch the dual-cam function on K-FX Plus, the primary USB camera must be connected to one of the designated ports Cam 1 within the rear connector group "USB Devices" and the secondary USB camera to the dedicated Cam 2 connector.

The dual-cam function is switched either via a function button of the 4K transmitter as described in chapter 11.4.9 button definition or via the GPI interface as described in chapter 11.4.8 GPI definition .

11.8.3 USB Audio (K-FX Series)

The USB camera menu can be used to check the function of the connected USB audio device (e.g. integrated microphone/speaker unit, a USB video bar or separate speakerphone) and to check the basic compatibility with Klick&Show K-FX Series base devices for use in BYOM online meetings.

If you have connected several USB audio devices at the time of testing, select the USB device to be tested in the list of devices. Note that depending on the type used Klick&Show Basic and third-party device may take a few seconds to activate.

If multiple USB audio devices are connected Klick&Show base device, only one of these can be used later in conference operation. In contrast to switching two USB video sources on K-FX Plus as described in Chapter Title 11.8.2 , switching two audio devices is not provided.

Hint:
If the playback of the video image or the audio signal does not work properly, please first check whether the USB connection is correct. The camera and audio devices must be connected to the USB ports on the back of the base device. Please use a USB cable that is as short and high-quality as possible for the test.

Please also check whether your hardware is compatible with Kick&Show basic devices of the K-FX series and in this context please note the section "Compatibility with third-party devices" in chapter 3.1 Features/Compatibility.

Please also see the list of successfully tested third-party devices "List of compatible UC devices" at www.klickandshow.com/kfx-plus-download/, as well as the document "K-FX BYOM Setup in 3 Easy Steps".

If all of the above information does not lead to error-free operation of your USB device, use another existing USB device (e.g. a simple PC webcam) for a temporary test to isolate the error.
If necessary, contact our support team for further support during commissioning.

11.9 Screen Link

Explanations of the Screen Link function

The exclusive Screen Link feature allows you to link two Klick&Show The HDMI outputs and processors, which are now available twice, form a more powerful base system with dual monitor output and extended functionality.
The screen link function is part of the functionality of all Klick&Show Basic devices that only have 1 HDMI display output (including K-FX, K-40, K-WM), but not K-FX Plus, as this top model already has two monitor outputs as standard.
To build a Screen Link function, any basic devices from the series Klick&Show K-FX, K-40 or K-WM.

To use the Screen Link, the two base devices must be connected via LAN port 1 via Ethernet cable to exchange video/audio and control data. In this case, either direct cabling must be provided using "crossover" Ethernet cables or structured cabling via an IP switch with automatic crossover function and standard (uncrossed) Ethernet cables.

How to Use the Screen Link Feature

The WebUI page "Screen Link" can be used to activate and configure the use of the Screen Link. Here, one of the base devices is defined as the "primary" device and the other base device as the "secondary" device.

Hint:
The secondary base device can no longer be used as a stand-alone system in the Screen Link operating mode. Any transmitters belonging to the secondary device must be paired to the primary device for use with Screen Link and are therefore no longer available on the secondary device.
For these reasons, Screen Link is not intended to support two separately used Klick&Show systems can only be combined temporarily (for example, into 2 halves of a divisible room).

With the Screen Link function, a double monitor output for up to 5 participant content (4+1) takes place. The mode setting can be used to predefine whether either:

The first source always remains in full screen display (Primary 1 / Secondary 4)
or
The last source always remains in full screen display (Primary 4 / Secondary 1)

The following table gives an overview of how the image outputs are performed on the primary or secondary monitor, depending on the mode setting, as the number of displayed participant content increases:

Primary-Secondary Device:	Primary	Secondary
Mode setting:
Primary 1 / Secondary 4	First Source always remains in full-screen display	1 Source: same content on primary and secondary 2 sources: both contents in full screen display 3-5 Sources: Secondary shows sources 2-5 as PiP
Primary 4 / Secondary 1	1 Source: same content on primary and secondary 2 sources: both contents in full screen display 3-5 Sources: Primary shows sources2-5 as PiP	Last Source always remains in full-screen display

To set up a screen link:

Decide whether you want a particular source to have special meaning in your scenario (for example, a presenter's image content).
In this case, set the base unit assigned to the preferred screen (left/right) as "Primary" and select the mode setting "Primary 1 / Secondary 4" so that the first mirrored source always appears in full screen mode on the primary display, while subsequent content is shown on the secondary display.
In the other case, if the content in your scenario is more likely to have the same relevance, then set the base device associated with the screen (left/right) that will show the last mirrored content in full screen size as your "Secondary" and select the mode setting "Primary 4 / Secondary 1".

Tip:
The Screen Link function is particularly advantageous for applications that benefit from the output of various image contents, for example:

Presentations that often compare different content
Web conferencing in companies, with visualization of remote participants and local content
In education, if the content of a lecturer should always remain visible in full screen size and simultaneously changing content of students is displayed

Hint:
When the Screen Link function is activated, the primary device is used to receive all user content wirelessly. All existing transmitters are paired to the primary device and are no longer available for use on the secondary device.
The secondary device receives the content intended for display on the secondary display from the primary device and only takes over the decoding of the content and HDMI output. In order for the primary and secondary devices to communicate via the Ethernet connection, when Screen Link is activated, the DHCP protocol is automatically deactivated on the respective Ethernet port 1 and a static IP address for LAN 1 is assigned to both devices instead. The primary device is set to IP 192.168.10.1, the secondary device to 192.168.10.2. These addresses must not be changed, otherwise Screen Link will no longer work.

13. Telnet/RS232 commands

Klick&Show can be controlled by the commands below via RS232 or Telnet.
Ports :23 and :5656 are used for Telnet control.

Hint:
The possibility of control via Telnet depends on the security level set. It should also be noted that in the case of the Klick&Show base devices K-WM, K-40 and K-FX, Telnet control can only take place within a Class C network (subnet mask 255.255.255.0). On newer Klick&Show K-FX Plus devices do not meet this restriction.

Here are some basic problems and possible causes that occur during the use of Klick&Show can occur. Use the solution hints provided.

If you are unable to resolve the issue, contact your reseller or IT administrator.

problem	cause	solution
When plugging the transmitter into the computer , the LED flashes solid green. The Klick&Show App does not start and no connection is established.	The Klick&Show App for Windows or macOS hasn't been running on your computer yet, or it's gone, or it's corrupted.	Chapter 6 describes how to download the software.
	You have decided to use „Klick&Show for Windows Portable".	The "Portable" version of the app must be started manually before each use.
	Due to administrative restrictions on your computer, entries cannot be made in the Startup menu.	Please contact your administrator to remove these restrictions. Alternative to the standard version of Klick&Show for Windows, you can Klick&Show for Windows Portable without installation. However, the application must be used before each use of Klick&Show can be started manually.
	Windows: The execution of .exe files is blocked by the administrator. Due to an active antivirus program , it can happen that the Klick&Show App is blocked.	Please contact your administrator to remove these restrictions or use an HDMI or USB-C transmitter. These behave like an external monitor and therefore do not require any software on the computer. We review the Klick&Show apps regularly check for virus attacks. Configure your anti-virus program's filters accordingly so that they are allowed to run. With centrally managed antivirus protection, you need the assistance of the administrator.
	The use of USB ports is blocked due to a company policy.	Please contact your administrator to remove these restrictions or use an HDMI or USB-C transmitter. These behave like an external monitor and therefore do not require any software on the computer.
	The transmitter is defective.	Test another transmitter to confirm the conjecture. Please contact support.
	The network settings of the Klick&Show Base has been changed or the base has been reset. The transmitter therefore does not yet know the new connection parameters.	Pair the transmitter again, see Chapter 5.9.
When the transmitter is plugged into the computer, the Klick&Show app, but the message appears: "Connection failed".	The network settings of the Klick&Show Base has been changed or the base has been reset. The transmitter therefore does not yet know the new connection parameters.	Pair the transmitter again, see Chapter 5.9.
	The USB port did not recognize the transmitter correctly.	Reconnect the transmitter or use a different USB port on the computer. It may help to restart your computer.
Error message: "The version of the Klick&Show App (of the WirelessMedia Client) does not match the firmware of Klick&Show.	It is a newer version of the Klick&Show app available or the firmware of Klick&Show has not yet been updated.	You can ignore this message. The basic function (image transfer) is still given, but newer features may not be usable. Download and run the new software or ask the administrator to update the firmware.
The "WirelessMedia App for Android" does not work.	Check if your Android device is on the same Wi-Fi network as the Klick&Show .	Choose the right Wi-Fi network and refresh the device list and select the one you want Klick&Show from.
The Wi-Fi connection between the transmitter or computer and theKlick&Show Base is not stable and keeps breaking off. Transmitters may flash green in such cases.	The Klick&Show The Wi-Fi connection in use is disrupted, e.g. due to a conflict with other Wi-Fi networks that use the same channel.	Use a Wi-Fi scanner app (e.g. Wifi Analyzer) to find a suitable Wi-Fi channel and change the Wi-Fi configuration from Klick&Show manual. Repeat the process regularly if Wi-Fi networks in the area are frequently changed.
	The signal strength is too low. Walls made of plasterboard or reinforced concrete can dampen the signal and cause reflections that interfere with the WLAN signal.	Reduce the distance between the computer and the access point, or place Klick&Show or the access point in a more suitable position in the room. Change the antenna orientation. If possible, eliminate obstructions in the line of sight between the two devices. Avoid it Klick&Show in (metal) cabinets, suspended ceilings, under tables or in neighboring rooms. Please note the information in chapter 5.1.1 Installation and alignment of WLAN antennas
Poor video quality (image sharpness, image and sound dropouts, video stream stutters,....) when using the Klick&Show App.	The video quality depends on the computing power and processor load from other running software applications when transmitted via app. A laptop can be configured on reduced computing power when running on battery power.	Reduce CPU usage by other applications. Reduce the playback resolution on the computer. Exit the power saving mode. Use an HDMI or USB-C transmitter, these work independently of the computer's performance through internal hardware acceleration via chip.
	Poor Wi-Fi connection	see above
A video does not appear on the main screen.	The content is HDCP protected.	Klick&Show does not support HDCP encoded source signals.
The transmission stops and the transmitter's LED flashes.	The WLAN connection was interrupted.	Klick&Show tries to reconnect automatically. If this does not work, the transmitter's LED will flash green. Unplug the transmitter and plug it back on. If the connection cannot be restored, check the Wi-Fi environment.
Nothing is displayed on the main screen or the image quality of the home screen is poor.	The display is turned off or an incorrect input has been selected.	Turn on the display or select the correct input.
	The HDMI cable is not plugged in correctly, damaged or the quality of the cable is too poor.	Establish a working connection between the HDMI output and the display.
	The display detects the resolution of the Klick&Show not, or cannot represent it.	Change the resolution in the "Display & Audio" web menu. It is best to set it to Auto or manually to the native resolution of the display, which you can find in the data sheet.
	The Klick&Show Base is in stand-by mode (ring LED on the top of the Klick&Show base is slowly flashing green) or there is no power supply.	Connect the power supply. Press the power button on the Klick&Show or connect via transmitter or Klick&Show App with the base. Stand-by ends automatically.
The touchback function of the display does not work in conjunction with Klick&Show	The touchback function requires a separate USB cable between the display and the Klick&Show Base unit.	Connect the touch display to the USB cable Klick&Show.
No LAN connection to the base.	The network cable is not plugged in. That Klick&Show Base device did not receive an IP address via DHCP. Your laptop is in a different network segment.	Plug in the network cable and contact your network administrator to verify the correct network integration.
You don't hear any sound on the display.	There are no speakers or the volume control has been adjusted to zero.	Connect speakers or increase the volume.
	The volume level in the Klick&Show has been limited.	Adjust the audio output in the web menu of Klick&Show at.
	The volume level is set in the options of the Klick&Show App set too low.	Adjust the volume in the options of the Klick&Show app.
	The audio output on the computer has been disabled. (Mute)	Enable audio output.
The sound is output on the computer and not by the Klick&Show to the display.	On your computer, the wrong audio output device is selected.	Select the correct audio output device (Klick&Show) in your computer's audio settings.
You don't hear any video sound with the MacBook.	The Klick&Show App integrated "Soundflower" app is not installed.	You need the "Admin Password" for MacOS: open system settings\Security Run/install the soundflower "Matt Ingels"=>"allow" WirelessMedia.app driver again.
When you insert the USB-A transmitter into a MacBook, you will be prompted for a password.	The "Soundflower" app in the WirelessMedia Client requires a local installation.	You need the "Admin Password" for MacOS: open system settings\Security Run/install the soundflower "Matt Ingels"=>"allow" WirelessMedia.app driver again.
You cannot connect the firmware to the Klick&Show Update base.	The USB flash drive is formatted with the file system NTFS.	Use a USB drive with FAT/FAT32 formatting for the update.
AirPlay does not work.	The use of AirPlay has been improved in the security settings of Klick&Show deactivated. Klick&Show is operated in infrastructure mode. To use AirPlay, certain network ports must be enabled.	Contact your administrator to enable this feature or to perform the necessary network configurations.
The image quality when playing video via AirPlay is poor.	There are 2 states for AirPlay: Mirroring: 1:1 Copy of the screen Streaming: Videos (Internet, youtube; the image is not displayed on the iOS device. => image is jerking	Reduce "quality" in the video, e.B. from "automatic" to 720p.
"WirelessMedia2" for Android does not transmit sound.	Android does not allow apps to access the audio signal.	Most Android devices support Miracast,which also allows the transfer of audio.
Integration into a company network
Mobile devices do not find the base device.	Certain network ports must be shared for data transfer.
	Klick&Show and mobile devices are not on the same subnet.	Contact the administrator to make the necessary network configurations.
Poor transmission quality	Poor Wi-Fi connection	Contact the administrator to improve the WLAN supply or to optimize the network configuration.
