3. Product description

Kindermann Klick&Show K-FX, K-40 and K-WM are wireless presentation systems for huddle spaces, meeting and training rooms, classrooms, etc. where flexible presentation is important. Klick&Show enables the screen of computers, tablets or smartphones to be transmitted wirelessly and presented to a central screen – without lengthy configuration, cables and waiting times. This makes the use of personal devices (BYOD – Bring Your Own Device) a breeze.

Klick&Show K-FX extends the functionality with a conferencing function for the use of USB cameras, speakerphones, video soundbars, etc. that are permanently installed in the room and connected via USB to the Klick&Show K-FX base. Thanks to USB-over-WiFi, these can be used wirelessly for UC conferencing with a PC or notebook as if they were directly connected.
This makes it easier for hybrid teams to collaborate on video conferences (collaboration between office and home office or on the road), because each meeting room or huddle space can be used easily and spontaneously with your own UC or video conferencing account.

There are various transmission paths to choose from for the wireless transmission of content, first and foremost the Klick&Show Transmitter with HDMI or USB-C interface, which allows the use of KLICK&SHOW make it particularly easy. Both types of transmitters allow you to share the PC screen without installing any software. Klick&Show Transmitters are compatible with the K-FX and K-40 base units.

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

In addition, the generic protocols AirPlay, Miracast and ChromeCast (GoogleCast) are supported for image transmission. These are available directly on the respective 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 allow the simultaneous display of up to four device contents in a split-screen display.

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 as possible to the playback device to avoid problems with HDMI signal transmission.

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 aligned vertically.
• 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.
• Due to the special radiation properties of the dipole antennas, you should use the Klick & Show Do not install the base directly above or below the transmitters (under/ceiling mounting).
• When installing a Klick&Show Base within an area shielded from radio waves (e.g. 19 inch built-in metal cabinet), 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 separated from the base by means of an extension cable and positioned outside the shielding area.
  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 supplied, with various regional adapter attachments:
K-FX: 12 VDC / 3A,
K-40 / K-WM: 12 VDC / 1.5A

Adapter Types:

1. Mount the required type plug adapter of your country.
2. Connect the power supply to the base device.
3. 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 can also be provided via the network cable on the LAN2 port. 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.
That Klick&Show K-FX base unit requires a power supply according to PoE 802.3at (PoE+) in the case of connected USB UC devices.

5.4 HDMI port

Connect the HDMI output of the base through a suitable HDMI cable to a display or projector.

hint:
All Klick&Show Base device types support output resolution up to 4K (3840 x 1920 pixels) at 60Hz refresh rate.
Please make sure to use suitable cables that can transmit this resolution, especially for longer cable runs.

5.5 Audio connectors

The transmitters or the WirelessMedia Software Client transmit the audio signal from the computer together with the video signal to the base device. Even when using native transmission protocols such as Airplay, Miracast and GoogleCast, audio and video are transmitted together.

HDMI audio output:

Image and sound are transmitted digitally via HDMI. A playback device, e.B a display with speakers, can play the sound directly.

Analog audio output
The sound is output analogously at the jack socket "LINE OUT". Here, active speakers or existing analog audio systems can be connected.

Audio configuration on the PC/laptop
In the factory setting, KLICK&SHOW mute the computer's internal speaker and transmit the sound to the Klick&Show Base as soon as an image is transmitted.
If the transmitter is unplugged or the WirelessMedia Software client is closed, the previous audio configuration of the computer is restored.

• 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 separate network interfaces, so it can be connected to two separate networks. The IP addresses used by the Klick&Show from the respective network are displayed on the home screen.

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

1. 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.
2. to use the moderator function.
3. to use the integrated whiteboard/annotation app.

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 Klick&Show Base device, which outputs the captured content via HDMI to the display device.
The required software is the WirelessMedia Software Client, which is available for Windows and MacOS operating systems.

A description of the commissioning and use of the WirelessMedia Software Client can be found in chapter 6.2.3. (for Windows) or in chapter 6.2.4 (for MacOS).

If you Klick&Show To use the K-40 in conjunction with a USB-A transmitter for the first time, you must first run the WirelessMedia Client. If the program has been executed once, the WirelessMedia Client is started automatically when the transmitter is plugged in.

Hint:
No admin rights are required to run the WirelessMedia Client. However, an entry is made in the registry. In the Autostart section, the WirelessMediaAutoStartC3.exe service is set up, which ensures that the WirelessMedia Client starts automatically when the USB-A transmitter is plugged in.
If, for example, a group policy (e.g. via Active Directory) blocks the installation of "auto-starting software", you can use the "WirelessMedia Portable for Windows" version. This does not require any installation at all. However, the "Portable" version of the client must be started manually before each use!

Plug the transmitter into a USB-A port of your computer. As soon as the LED indicator of the dongle lights up solid green and the color of the WirelessMedia Client changes to green, the system is ready for use.

Now you can touch the surface of the transmitter to activate the transmission or you can click with the mouse on the "Show" button in the WirelessMedia Software Client. The transmitter will confirm the activation with a color change to red. The WirelessMedia Client also turns red.
Your computer's screen will now be broadcast to the base and displayed on the connected main display. The user name of the computer is briefly displayed.
To end the broadcast, tap the transmitter again or click the red "Stop" button in the WirelessMedia Client.

After use, you can simply untract the transmitter from your computer.

6.2.3 Screen sharing via WirelessMedia Client for Windows

If the WirelessMedia Client is not yet available on your computer, you have the following options to choose from:

In this case, please contact your network administrator.

To exit the WirelessMedia Clients click on the Close icon (red dot) or in the system tray with the right mouse button on the Icon and then click Exit. A confirmation dialog follows.

Advanced features of the WirelessMedia Client for MacOS

click the gear icon in the app to use the "options" or close.

Options:

• 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.

• Lowest latency (mouse):
  The option is active by default. The mouse pointer is displayed without any perceptible 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.
  
  Deactivated: The shape of the mouse pointer (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).
  
• Share Mode:
  This option allows you to choose between two presets for encoded transmission of image information.
  
  – Fluent priority: In the case of fast-moving images, the quality is somewhat reduced in favor of a smooth display.
  
  – Quality priority: In order to ensure 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).

6.2.5 Supplementary Operating Instructions for the WirelessMedia Client

If the WirelessMedia version does not match the firmware of the base, you will be informed by a message after starting the app:

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

Hint:
A right-click on the icon in the taskbar, the Klick&Show Context menu. The software tells you versions of the base device, the transmitter and the WirelessMedia Client.

6.3 USB-Conferencing K-FX)

Klick&Show K-FX transforms 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 your conference room, such as video or sound bars, cameras and hands-free kits.

In this concept, known as BYOM (Bring Your Own Meeting), employees can 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.

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

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.

Connect the transmitter to the computer as described in Chapter 6.2.1. In addition to the screen sharing feature (which does not require a driver), the transmitter is recognized as a "CD drive" (non-writable memory) on which the WirelessMedia Client is mounted.
When using transmitters, they take over the (driverless) mirroring of device content to the main display, while the WirelessMedia Software Client 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.

Under Windows 10/11, an AutoPlay message window automatically appears when the transmitter is connected. Click on this message window and confirm that you want to run WirelessMedia.exe from this disk. If, in rare cases, the AutoPlay function is deactivated on your computer, either activate it beforehand or start the WirelessMedia .exe manually from the virtual CD-ROM drive by double-clicking on Windows Explorer.

The Windows Autoplay hint window only needs to be observed on the first run. After the first successful start-up, the autoplay message can be ignored, as the already installed WirelessMedia Client opens automatically in the background after plugging in the transmitter.

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 WirelessMedia software will prompt you to install the drivers.

Hint:
To use the conferencing (BYOM) functions under K-FX, administration rights are required during installation.
Alternatively, the WirelessMedia Client 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 the 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.

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

If the subscriber laptop and base are already in the same network address range, a connection is immediately established to receive the USB device data streams. In the other case, if the laptop is connected to a foreign network at the beginning, from which the Klick&Show If the base is not accessible, the WLAN connection must be changed accordingly.

The WirelessMedia Client then automatically notifies the user of the need to change the network and also carries out the change independently after confirmation. As a rule, the WLAN password is transferred when pairing the transmitters, so that manual entry is not necessary.


For information about network configuration, see the Chapter Network Settings.

6.3.2 Commissioning USB conferencing with the WirelessMedia Client (K-FX)

If the WirelessMedia Client is not yet available on your computer, you have the following options to choose from:

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

Connect your computer to the "GUEST" or "EMPLOYEE" Wi-Fi network that is displayed on the home screen.
Run the "WirelessMedia Client" by double-clicking. A list of all available Klick&Show in network is displayed. Choose the Klick&Show that you want to connect to, and then click "Connect".
As a rule, access is password-protected .
Enter the 8-digit "code" that is displayed on the home screen. When you have successfully connected to the base, the WirelessMedia Client changes color to green.

Hint:
If the desired Klick&Show Base does not appear in the list, you can enter the IP address directly in the black box and then click the click.
In this case, your computer is either not connected to the same network (segment) or there are network-side restrictions that block an automatic scan.
In this case, please contact your network administrator.

If a USB camera and/or a USB audio conferencing product has already 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 WirelessMedia software will prompt you to install the drivers.

Hint:
Administration rights are required for installation.
Alternatively, the WirelessMedia Client and the function drivers for the Windows operating system can already be pre-installed via central software distribution.
The MSI installation package can be found on the 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.

6.3.3 Wireless use of camera and audio conferencing (K-FX)

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

Example Microsoft Teams:

Example Zoom:

In other UCC software clients, the setting must be made 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.

As soon as the camera or audio transmission is used, the color on the icons on the home screen and in the WirelessMedia Client changes to green for status feedback.

  This allows you to choose between high display quality and improved performance.

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

6.6 Use of Miracast

Klick & Show 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, Klick&Show operate in one of the two infrastructure modes and the computer or mobile device must be connected to the appropriate network.

K-FX already supports these two modes as standard. For K-40 and K-WM the optionally available 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 keyboard shortcut 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. Choose Klick&Show and enter if necessary.

7. Splitscreen, Moderation & Tools

Klick & Show offers in addition to the basic function of screen sharing other helpful tools that can support users in the presentation and contribute to a productive meeting.

7.1 Splitscreen

In certain situations, it can be useful to display more than one screen, e.B. to compare different ideas or to show additional information that is difficult to combine on one screen.

Supported here Klick & Show the split-screen display of up to four sources simultaneously. You can select the number and display in the WebUI.

The split-screen function is automatically activated as soon as more than one device simultaneously drives the image transmission. The assignment of the positions is done automatically depending on the order of the presentation.
As soon as a fifth source wants to be displayed, it "pushes" the first one out of the picture.

Hint:
To switch its screen from split screen to full screen, you can press and hold the dongle for 2 seconds.
In the WirelessMedia 2 app for Android, the "Full Screen" button performs the same function.
Airplay and Miracast do not support this feature, so all other devices must separate so that these devices can present in full screen.

7.2 Moderation

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

The sidebar displays all connected devices and can be brought to the presentation by the presenter. 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 Coupling of transmitters (pairing)

If you Klick&Show as a set, the transmitters included in the set are already coupled to the respective base at the factory and are immediately ready for use. However, as soon as you change the network configuration or if you purchase additional transmitters, for example, you will have to re-pair them.

Note: What does pairing mean?
The base and transmitter communicate with each other via WLAN. As with a computer or mobile device, the transmitter must know which WLAN network (SSID) to connect to and which password it uses. This information is exchanged during pairing. At a certain point in time, a transmitter can only be operated with one Base be coupled. The transmitter automatically connects to the last paired base.

Plug the transmitter's USB port into one of the USB sockets on the Klick&Show Base. The transmitter will be automatically detected and the process will start. In a first step, if necessary. first checked the firmware of the transmitter and, if necessary, automatically carried out an update. This may take a few minutes. A message on the main screen will show the history. The actual pairing then takes place in a second step.

If you see the success message on the screen, you can simply pull off the transmitter. Proceed accordingly with all other transmitters.

8.2 Firmware Update for Transmitters

We develop Klick&Show to add new functions or to adapt to changing conditions in the IT environment. For this purpose, we provide regular firmware updates that are installed on the base.
In order to load the new firmware onto the transmitters, they must be plugged in there after updating the base.
The transmitter will be automatically detected and the process will start. The process can take up to a few minutes. The transmitter must not be removed from the base until then.

If you see the success message on the screen, you can simply pull off the transmitter.

hint:
Firmware updates for the transmitters are also transmitted to the transmitters in the background during use.
For installations with multiple devices, we recommend using the ManageTool. This allows all transmitters at the workplace to be coupled to any base.

8.3 Delete older versions of WirelessMedia for Windows

If you receive an error message when you manually run the WirelessMedia Client or plug the USB-A transmitter into a laptop, even though all programs have been updated, it is likely that an older version is active on your computer.

The cleaning tool WindowsClear or MacClear can delete the traces of the old version. Run this file and start the current version of the starter program.

8.4 Restore factory settings (Reset)

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

hint:
You can save the current configuration and read it back in after the reset.

• 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.

Note:
All settings are lost and Klick & Show needs to be re-set up.
After resetting to factory settings, all transmitters must be paired (paired) again with the base device.

9. Introduction to Network Configuration

9.1 Basic rules for WLAN

To ensure that the radio signals do not interfere with each other, "WLAN hygiene" is essential, i.e. You must ensure that only one access point broadcasts on each WLAN channel and, if necessary, on the directly adjacent channels. Otherwise, the signals overlap and interfere with each other. In the best case, the data rate decreases, in the worst case, data transmission is no longer possible.
There are various professional WLAN scanners on the market that help for a quick overview, but also free apps, such as the Wifi Analyser, which visually represent conflicts.

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 the channel in the 5 GHz band.
In order to achieve the best transmission quality, we propose a "line of sight" between the Klick&Show base and the transmitter or mobile device, so that radio transmission can take place unhindered. Avoid proximity to objects made of metal or other dense materials.
In difficult installations, it may make sense to install the antennas with an extension in a better place for reception, e.B. outside a technical 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:

1. Access Point Mode
   • Access Point Mode (with bridging)
2. WLAN Infrastructures Fashion
3. 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 Depending on the type of device (K-FX, K-40, K-WM) and the intended usage scenario, a connection to the corporate network may be optional or mandatory. Therefore, please note the overview of the supported network modes and the options for connecting to the corporate 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 notes:

• The integrated access point offers a particularly simple commissioning and use, therefore the access point mode is preset at the factory. This mode is distributed if there are comparatively few rooms in a building with Klick&Show , all of which then use their own Wi-Fi. For additional functions (provision of Internet to connected devices, BYOM conferencing with K-FX, remote administration, etc.), one (or two) additional wired network connection via LAN can be added at any time, even in access point mode.
• 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 base devices are integrated into the corporate network either wirelessly or wired. This can be useful in larger rollouts where many Klick&Show systems in comparatively close proximity. 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 the infrastructure modes then leads to better "Wi-Fi hygiene", as the transmission of the Klick&Show data streams then run over the existing Wi-Fi channels of the corporate network. However, it should be borne in mind that the required bandwidth must then also be ensured. (see note below.)
• In both infrastructure modes, but also in access point mode after expansion with LAN connection, Klick&Show accessible via the existing infrastructure and can be administered centrally. This is convenient and secure, as enterprise networks are usually actively managed 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 takes place either partially or completely over the corporate network, please remember to provide sufficient bandwidth for the network!
You can expect a data rate of 2 – 10 Mbps per active screen sharing (K-FX, K-40, K-WM).
For each active video transmission from the USB camera (for web conferences with K-FX), an additional data stream of 10 – 100 Mbps is generated.

In this context, you should be aware that in the case of a wireless connection of the base and especially the transmitters, their transmitting/reception quality – and thus the resulting transmission quality – depends largely on the structural conditions (distance of the company access point and materials to be penetrated with 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 to the base located in the immediate vicinity, possibly supplemented by further connections to the company network via 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)

At the first start-up or after the reset to the factory settings starts Klick & Show in access point mode, in which 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 changed via the web menu of the Klick&Show Configure the base.

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

In the "stand-alone mode" of the base, user terminals that are connected 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. Subsequently, via the web menu of the Klick&Show Base the bridging to be enabled to one of the LAN ports. Subscriber devices connected to the base's access point can now be connected to the LAN-provided network at the same time. See chapter 9.2.2 below Access Point Mode with Bridging.

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

hint:
In AccessPoint mode, the 8-digit code displayed on the home screen is also the WLAN password.

9.2.2 Access Point Mode with Bridging

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.

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!

When bridging is active, the icon for "Connected network (LAN + WLAN)" 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. This is then indicated by a small "1" or "2" in the symbol .

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.

The icon for "separate networks (LAN + WLAN)" is displayed on the home screen.

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 click & shows (in the immediate vicinity)

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

9.3.1 Wireless Infrastructure Mode

In Wireless Infrastructure mode, the internal WLAN function unit of the Klick&Show Base operated as a "station" in the "WLAN client" operating 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 WirelessMedia software client is also done via this network. The access parameters required for the external access point (SSID, password) are specified during configuration via the web menu of the Klick&Show Base deposited. By pairing, the transmitters receive the necessary connection information to connect to the 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 using LAN ports 1 and 2. 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 can be specified 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 a network cable via either LAN port 1 or 2. The transmission of content by means of Klick&Show Transmitter or WirelessMedia software client is also done via this network. The access parameters required for the external access point (SSID, password) are specified during configuration via the web menu of the Klick&Show Base deposited. By pairing, the transmitters receive the necessary connection information to connect to the network.

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 case of Klick&Show K-FX:

To conduct BYOM web conferences at 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 met at the same time:

1) Access Point Mode: A wired network connection must be made in such a way that the wirelessly connected user terminals are located in the same network area 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 base and to purely software-based BYOM connections via WirelessMedia PC client, since even when transmitters are used, the rear data stream of the USB conference devices always takes place directly to the WLAN of the user's laptop.

11.1.4 Network – Ethernet

From the Network Settings menu, select -> Ethernet

Hint:
Klick&Show has two LAN ports. These are separated, so both LAN networks remain segmented.
LAN2 also supports the power supply of the device via PoE and is Gigabit capable. Thus, the Klick&Show e.g. be connected to an in-house network and a guest network without establishing a direct connection between the two networks.

To configure, select the tab for the desired LAN port:

Proxy & 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".

The second LAN port can be configured separately according to the above pattern and has its own MAC address.

11.1.5 802.1X Authentication

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 IEEE 802.1X wired authentication feature 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 networkodi, with the limitation 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 allows the transmitters to connect to the internal access point of Klick&Show remain connected and only use the Klick&Show The 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 resolution

Select the resolution and refresh rate that the Klick&Show Base unit at the HDMI output.

The Klick&Show Base unit reads in advance the so-called EDID information of the output device (display, projector). The EDID is a data structure with which display devices of a connected signal source describe their capabilities.
The resolutions then listed in the list selection field of the WebUI depend on the capabilities 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 selects the EDID information of the playback device (e.g. display) and selects the best available setting. If you are not satisfied with the image quality, you can choose a suitable one from the list of available resolutions.

hint:
If the newly selected resolution cannot be displayed, the previously active resolution is displayed again after approx. 15 s.

11.2.2 CEC

CEC is the Consumer Electronics Control (protocol) standardized by the HDMI organization. Klick&Show supports the command sets for switching on and off. If your playback device
(e.g. display) is also compatible, the display or the Klick & Show Automate the basis about it.

If you select the "Klick&Show through the display", the display switches the Klick&Show Base on or off synchronously with the operation of the display.

If the option "Display through the Klick&Show", the display responds to turning the base on and off or plugging a transmitter into a laptop.

Both options can also be activated.

Hint:
Please check if the display or projector supports CEC. Sometimes only certain inputs on the device support CEC.

11.2.3 Audio output

The audio output can be done either via the analogue jack output and/or via the digital HDMI output. In the case of: Klick&Show For BYOM conferences, K-FX can also output audio via USB to a connected USB conferencing device, e.g. a video soundbar.

11.2.4 Volume

You can limit the playback volume, e.B. to avoid exceeding a certain level.

11.2.5 AirPlay image quality

You can choose from:

• High: 1920×1080 (default)
• Medium: 1600×900
• Low: 1280×720

hint:
The higher the quality the more data is transferred, a lower quality can mean a smoother transmission.

11.2.6 Homescreen Configuration

Here you can decide which information is provided by the Klick&Show on the home screen or during the presentation.

• Display the device name and password of the base when mirroring
  Displays the guest SSID and code in a small semi-transparent window during transmission.

The name of the HDMI and USB-C transmitters can be changed at this point, for example, the room assignment can be made.
The "Remove" button (garbage can) can be used to select individual or all devices and unpair (disconnect). Before the next use at this base, they must then be taught again.
In this way, abusive transmissions of stolen transmitters can be prevented.

11.4.2 Date and time

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.B. if there is no connection to the base and the Internet).
Optionally, the default time server on the Internet, e.B. can also be replaced by a local server.
Under the "Time Zone" tab, this 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

Auto Stand-by offsets the Klick & Show Base automatically enters the power saving mode if there is no connection or use of the device within the selected time.

In stand-by, the LED ring of the base flashes and the HDMI output is switched off. However, the network connection remains active. As soon as a device with the Klick & Show is connected, the power saving mode is terminated.
Pressing the POWER button on the front of the device or entering it on the connected touch screen also ends the energy-saving mode.

11.4.7 Serial interface (RS232)

The RS232 interface can be activated or deactivated in this menu. Via RS232, the Klick&Show base, e.g. can be remotely controlled by a media controller. Alternatively, the interface can also be used to control other devices.

Remote control of the Klick&Show Base via RS232:
To do this, configure the serial port function to "Klick&Show Taxes ". The control commands are identical to the Telnet commands.
You can take over the other settings (baud rate, etc.) or adapt them to the capabilities of the media control.

Remote control of external devices via RS232 by Klick&Show:
To do this, set the serial port function to "Klick&Show controls" and adapt the communication parameters to the technical requirements specified by the device to be controlled.
These can usually be found in the manual as a preliminary remark to the RS232 commands.

Commands can be stored for the following functions:

• Turn on
  (as soon as the power supply of Klick&Show was manufactured)
• Going to sleep (If Klick&Show goes into stand-by)
• Waking up (When Klick&Show ended stand-by)

The delay can be entered separately.
With ON/OFF, the stored command can be set active or inactive. The commands must be entered in ASCII.

11.5 Security settings

11.5.1 Security levels

You can set four different levels of security for the Klick&Show choose. Security levels 1 to 3 are predefined and cannot be changed. The "Custom" security level allows you to select the individual security features individually according to your needs. The first two security features are enabled at each level and cannot be disabled. In the factory settings, security level 2 is activated.

Change code/WLAN password automatically

The code secures the use of Klick & Show against unauthorized use. Depending on the network configuration, this is also the WLAN password (in Access Point Mode) or only serves to protect against interference by outsiders, e.B. accidental connection.
Changing the code regularly prevents a previous user from still being presenting after leaving the room.

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

• Never (= requires the individual configuration of the security levels)
• 5 / 30 minutes
• 1 / 2 / 4 / 24 hours
  

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. The transmitter must: 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 already secured with proprietary encryption before the actual wireless transmission to the base device (1st encryption level). In addition, a further level of data encryption takes place during the subsequent wireless communication between transmitters or software client for Klick&Show Based on WPA2 (2nd level of encryption).

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) even before the actual wireless transmission to the base device. In addition, a further level of data encryption takes place during the subsequent wireless communication between transmitters or software client for Klick&Show Basis by means of WPA2 (2nd encryption level).

11.5.2 Login password

The 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 during commissioning.
However, you can also disable password prompting for the administrator menu. To do this, tick "Disable password request".

11.5.3 Connection password

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

Please also refer to the list of successfully tested third-party devices at www.klickandshow.com/kfx-download/.
If necessary, please contact our support for further support during commissioning.

11.9 Screen Link

The exclusive Screen Link function allows you to link two Klick&Show HDMI outputs and processors, so that the now duplicate HDMI outputs and processors form a more powerful basic system with dual monitor output and extended functionality.

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

After activating the Screen Link mode, the desired settings can be made in the Screen Link menu. Here, one of the base devices is defined as the "primary" device and the other base device as the "secondary" device. The secondary base unit can no longer be used as a stand-alone system in this operating mode. To set up a Screen Link function, any basic devices from the series can be Klick&Show K-FX, K-40 or K-WM.

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:

1. Decide whether you want a particular source to have special meaning in your scenario (for example, a presenter's image content).
2. 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.
3. 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

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 USB-A transmitter into the computer, the LED flashes permanently green, the "WirelessMedia" software does not start and no connection is established.	The WirelessMedia Client for Windows or MacOS has not yet been run on the computer, or no longer exists.	Chapter 6.4 describes how to load the software.
	You have decided to use WirelessMedia-Pro for Windows.	This program 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.    Alternatively, you can run the "WirelessMedia-Pro for Windows" client without installation. However, the program must be used before any use of Klick & Show can be started manually.
	Windows: The execution of .exe files is blocked by the administrator. An active antivirus program may block the WirelessMedia app.	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 regularly check the WirelessMedia clients for viruses. Configure the filters of your anit virus program accordingly so that they are allowed to run. With centrally managed virus 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.
When plugging the USB-A transmitter into the computer, the "WirelessMedia Client" starts, but the message appears: "Connection failed".	The network settings of the Click & Show have been changed.  The transmitter does not yet know the new parameters.	Pair the transmitter again , see chapter 8.1.
	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 WirelessMedia Client does not match the firmware of the Click & Shows.	A newer version of the WirelessMedia Client is available or the firmware ddes Klick & Show has not been updated yet.	You can ignore this message.

The WirelessMedia app for Android will not work.	Check if your Android device is on the same Wi-Fi network as the Klick & Show is located.	Select the right Wi-Fi network and refresh the list of devices and select the desired Klick & Show  from.
The Wi-Fi connection between the transmitter or computer and theKlick & Show is not stable and breaks off again and again.	The WLAN connection is disturbed, e.B by other devices that use the same channel.	Use a WLAN scanner app (e.B. Wifi Analyser) to find a suitable WLAN channel and change the WLAN configuration of 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, remove obstacles in the line of sight between the two devices.  Avoid it Klick & Show in (metal) cabinets, suspended ceilings, under tables or in neighboring rooms.
Poor video quality (image sharpness, image and sound dropouts, video stream stutters,....) when using the WirelessMedia client.	The video quality also depends on the computing power and processor utilization by other, running software applications. A laptop can be configured on reduced computing power in battery mode.	Reduce CPU usage by other applications.Reduce playback resolution on the computer.  Exit the power saving mode. Use an HDMI or USB-C transmitter, these work regardless of the performance of the computer.
