10. RS232 / IP control commands

10.1 Introduction

This section describes the hardware specification and the control protocol via RS232 and IP interface. In the following, all ECUs that can send or receive commands via RS232 and LAN protocol are referred to as "media control".

10.2 Description

10.2.1 Hardware Specification

The connection to RS232 communication is located on the back of the display.

10.2.2 Settings of the serial interface:

positions	value
baud rate	38400 bps	(fixed)
Bits	8	(fixed)
Stop bits	1	(fixed)
parity	none	(fixed)
Data stream control	none	(fixed)

The display uses port 4660 for lan commands.

10.2.3 Network Settings

We recommend the use of the LAN interface with static assignment of the IP address, see Section 7.3.1.2.

10.3 Protocol

10.3.1 General

The RS232 and LAN commands are identical.

10.3.2 Protocol description

10.3.2.1 Command format

head	Each command always starts with "k" for Kindermann
Display ID	The default value is "01". The ID "99" means that the command is sent to all connected displays. In this case, only the display responds with the ID "01".
Command Type	For sending a command, there are two command types: • Set command: "s" • Get command: "g" The display always returns one of the following responses to a command: • Valid set command: "y" • Valid Get command: "r" • Invalid Set or Get command: "n"
command	The function command
value	Three bytes define the value
end	each command completes with "cr"

Structure of a send command (type "s" or "g") and the response command (type "r")

head	Display ID	Command Type	command	Value 1	Value 2	Value 3	end
1 byte	2 bytes	1 byte	1 byte	1 byte	1 byte	1 byte	1 byte

Structure of a response command (type "y" and "n")

head	Display ID	Command Type	end
1 byte	2 bytes	1 byte	1 byte

Example 1

Sending a set command with invalid parameter: Setting the brightness of the display to 137.

	head	Display ID	Command Type	command	Value 1	Value 2	Value 3	end
Send (ASCII)	K	01	S	D	1	3	7	<CR>
Send (hex)	0x6B	0x30 0x31	0x73	0x44	0x31	0x33	0x37	0x0D

	head	ID	type	end
Answer (ASCII)	K	01	N	<CR>

Example 2

Sending a Get command with a valid response: Query the contrast value from the display, the command is valid and the set value is 53.

	head	ID	type	command	Value 1	Value 2	Value 3	end
Send (ASCII)	K	01	G	A	0	0	0	<CR>
Send (hex)	0x6B	0x30 0x31	0x67	0x61	0x30	0x30	0x30	0x0D
Answer (ASCII)	K	01	R	A	0	5	3	<CR>
