Control commands
Description
: The following commands with <A/V/AV> option can take effect in multiple
layers, according to th
eir parameters. Depending on ‘A’ or ‘V’ it can change only the Audio,
or only the Video layer; or ‘AV’ changes both.
Info:
<A/V/AV> option usually can be skipped for legacy purposes.
In this case using router commands the router changes all (Video & Audio) layers, but using
status commands it displays information about only the Video layer.
Please use AV option, when available.
Usually the commands are sent one by one to the router, but this is not a must. Any
command can be send to the router in a batch. To do this, just use the same commands
(including { } brackets), but put the “
CrLf”
only at the end of the batch.
The below example shows a batch command that resulted group switching:

Description
: This command switches an output to an input.
Format
Example
Command {<in>@<out>
