1 About this Guide
This guide explains how to control the ICP-401UHD (hereafter referred to as “ICP”) using commands through
LAN communication.
■Communication commands enables the following main operations:
・Switching and saving window pattern
・Setting input, output, and EDID
・Setting preset memory

2.1.3 Setting up LAN communication
(1) Connect the ICP and the control device via a LAN cable.
(2) Set up LAN communication as follows:
・Set IP address and subnet mask
・TCP pot number: 1100, 6000 to 6999
【Reference: User guide】
(3) Establish the connection from the control device to the IP address and TCP port that are set to the
ICP in step (2) above.
(4) Send a communication command from the control device to the ICP in order to check the control
status of the ICP.

2.1.4 The number of TCP-IP connections
The ICP supports up to eight simultaneous TCP-IP connections (eight logical ports).
To maintain optimal system accessibility, it is advisable to issue “port-open” and “port-close” commands
before and after command or query strings are issued. This approach enables eight or more control devices
to be effectively interfaced simultaneously and without concern for communication errors.

Note:
As a safeguard, the ICP incorporates a 30-second timeout window for each port. If any port is inactive for
more than 30 seconds, it will be closed automatically.

3 Command
3.1 Summary
A command consists of “@” (“40” in hexadecimal), 3 one-byte alphabetical characters (upper and lower
cases), followed by parameters (one-byte numbers). For some commands, multiple parameter values can be
specified or parameters are not necessary. Processing is executed by sending a delimiter at the end of the
command.
Example: @SPM,2
“,”( a comma, “2C” in hex) is indicated between a command and parameter and between two parameters.
“ ” is indicated as a delimiter CR LF (return+line feed, “0D” and “0A” in hex).
An error command is returned if an undefined command or wrong parameter is included.
Example:@SSW,1
@ERR,1
If only delimiter is sent, command list as the help command is returned.
Example:
[ HELP ]
@RWM: Recalling Window Pattern
@RPM : Recalling Preset Memory
@GIV : Getting Product ID & Firmware Version
