6.8 RS-232 and Telnet Commands
6.8.1 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”, “HDMI_Out”, “HDBT_
Out”, 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
following syntax to set or change a single parameter for a single slot
assigned to an HDBaseT or HDMI output port.
ZoneAvPair HDBT_Out {Port} Slot {Slot} {Parameter [= Value]}
Examples: ZoneAvPair HDBT_Out B Slot 5 VideoSrc = HDMI_In 2
ZoneAvPair HDMI_Out H Slot 3 Load
• Multi-Port Command Format
Use the following syntax to set or change a single parameter for
multiple ports. Note that each additional port uses the “+” character
