AT-UHD-CAT-XX
3
Commands
IMPORTANT:
Each command is terminated with a carriage-return (0x0d) and the feedback is
terminated with a carriage-return and line-feed (0x0a).
This document provides an alphabetical list of commands available for AT-UHD-CAT series of products.
Commands are case-sensitive. If the command fails or is entered incorrectly, then the feedback is “Command
FAILED”. Commands can be sent using RS-232, Telnet, SSH, or TCP. There should be a 500 millisecond delay
between each command sent to the unit. The default port for Telnet is 23. TCP ports are 9000, 9001, and 9002.
This product can communicate directly with local and remote RS-232 (over HDBaseT) ports using a direct TCP
socket connection. Refer to the table below for the port assignment for this product. For ports connected to RS-
232 interfaces, no additional payload is required to transmit data to the device. All data sent to the respective TCP
port will be sent bit-for-bit to the RS-232 output. Note that if feedback is required from the RS-232 device, the TCP
socket must be kept open. This product does not provide buffer or queuing registers. Therefore, any data from the
RS-232 port that is received while the TCP socket connection is closed, will be lost.

HDBaseT RS-232 port
9002
Local RS-232 port
Example:
With the device IP address of 192.168.1.100 and a PJLINK projector connected to the RS-232 of the HDBaseT
output.
1. Open a TCP socket to 192.168.1.100:9001 and send the following command string:
%1POWR 1\x0D
2. The projector will respond with the following, using the same socket connection:
$1POWR=OK\x0D
