RS-232 and
Telnet Commands
Command Syntax
The RS-232/Telnet command structure for this unit is both flexible and
powerful, and allows for multiple parameters to be set across multiple
ports simultaneously within a single command transmission. This section
will detail the command syntax used to send both simple (single port/
single parameter) commands as well as the more complex (multi-port/
parameter) commands.
The following multi-function syntax is specifically for use with these
commands: “ZoneLineOut”, “ExtLineOut”, “AudioCAT_Out”, “HDMI_Out”,
“HDBT_Out”, “MixerOut”, and “Pattern”. “ZoneAvPair” has a special
structure that will be explained separately. All other commands must be sent
within discrete transmissions.
•
Basic Command Format
Use this syntax to set or change a single parameter for a single input/output
port.
<Command> {Port} {Parameter [= Value]}
Examples: ZoneLineOut B Treble= -12
HDBT_Out A Mute

Basic Command Format (ZoneAvPair)
The ZoneAvPair command requires multiple variables to define the
location of the slot’s value to adjust. This command only accepts 3
possible parameters: “VideoSrc”, “AudioSrc”, and “Load”. Use the
