Command Structure - Issuing
The RS232 serial control structure of the Concert XR series is a string of
hexadecimal values with a minimum of six bytes. When issuing a command,
the structure of the string is as follows: Start Transmission, Zone Number,
Command Code, Data Length, Data and End Transmission. We will use an
abbreviated form for easy reference in the following format:
<ST><ZN><CC><DL><Data><ETR>

To change the source (both audio and video), the command is the 0x08 – IR
simulation command. See page 36 for more info.
