4K 4x4 HDMI®Matrix
PN 15750 RS-232 GUIDE

2
INTRODUCTION
This Blackbird™ device can be controlled by a computer using an RS-232 serial connection
and by issuing commands using RS-232 control software.
CONNECTION
This device includes a 3-pin Euroblock Terminal. Use this terminal to construct an RS-232
cable, which can be used to connect your PC to the matrix to allow for matrix control. The
following images show how to create and connect an RS-232 cable. If your PC lacks a DB-9
serial port, you will need to use a USB to Serial adapter cable (available separately P/N
3726).

3
SOFTWARE
This device does not include either a built-in control system or custom RS-232 control
software. If you wish to control this device from your PC using an RS-232 connection, you
will need to use a third party RS-232 control software package, such as CommWatch.exe,
whose interface is depicted below.
Set the communications parameters to the following:
Baud Rate: 115200
Data Bits: 8
Stop Bits: 1
Parity Bits: None
TCP/IP Port: 8000

RS-232 COMMANDS
The following guidelines apply to the RS-232 control commands.
1. The brackets [and ]in the commands are for clarity purposes to make the variable
more obvious. Do not type these symbols when typing the commands.
2. Other than the brackets, type in all commands exactly as they appear, including any
spaces. These commands are case sensitive and require the trailing exclamation
point (!) as part of the command.
3. Disconnect all HDBaseT™ receivers from the matrix/transmitter prior to performing
any of the upgrade commands.
