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 to DB-9 RS-232 cable, which is used to connect your PC to it to
allow for RS-232 control. 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). Refer to the full User's Manual for
connection details.

SOFTWARE
Web GUI RS-232 Control
You can issue RS-232 commands using the RS232 tab of the built-in Web GUI system. Refer
to the full
User's Manual for connection details to use this interface.
Port: Use the pull-down list box to select Local, which refers to the RS232 port of the
scaler/switch, or HDBT, which refers to the RS232 port of the HDBaseT™ receiver.
Baud Rate: Use the pull-down list box to set the baud rate. The baud rate for the Local
port is fixed at 9600, but the HDBaseT receiver can accept other baud rates. The
available baud rates for the receiver are 2400, 4800, 9600, 19200, 38400, 57600,
and 115200.
Command: Type the desired RS-232 command in to the text field.
Hex: Check the Hex checkbox if the RS-232 command is in hexadecimal format. Leave it
unchecked if the command is in decimal form.
Send: Click the Send button to send the RS-232 command to the selected RS-232 port.
: Click the icon to display the Control screen.

5
RS-232 Control Software
Rather than using the Web GUI interface to issue RS-232 command, you can 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: 9600
Data Bits: 8
Stop Bits: 1
Parity Bits: None

6
RS-232 COMMANDS
The following guidelines apply to the RS-232 control commands.
1. The xx in the commands are variables. Specify a value within the variable range to
complete the command or read the value in the feedback.
2. Other than the variables, type in all commands exactly as they appear. They are case
sensitive and require the trailing percent sign(%) as part of the command.
