Basic routing commands
Command
Syntax
Response
Switch audio & video
AV IN>OUT, IN>OUT , … AV IN>OUT, IN>OUT ,…RESULT
Switch video only VID IN>OUT , IN>OUT, …
Short form: V IN>OUT, IN >OUT, …
VID IN>OUT, IN >OUT, …RESULT
Note:
When AFV mode is active, this command will switch also audio. If audio is breakaway – device display mode will
change to show audio connections status.
Switch audio only AUD IN>OUT , IN>OUT, …
Short form: A IN>OUT, IN>OUT, …
AUD IN>OUT, IN>OUT , …RESULT
Note: When AFV mode is ac tive, this command will swit ch also video.

Parameters Description:
IN = Input number or '0' to disconnect output.
'>' = Connection character between in and out parameters.
OUT = Output number or '*' for all outputs.
Examples:
Switch Video and Audio input 3 to output 7 #AV 3>7CR ~AV 3>7 OKCRLF
Switch Video input 2 to output 4 #V 2>4CR ~VID 2>4 OK CRLF
Switch Video input 4 to output 2 in machine
number 6 #6@VID 4>2CR ~6@VID 4>2 OK CRLF
Disconnect Video and Audio O utput 4 #AV 0>4CR ~AV 0>4 OK CRLF
Switch Video Input 3 to All Output s #V 3>*CR ~VID 3>* OK CRLF
Chaining Multiple
commands* #AV 1>* | V 3>4, 2>2, 82>1, 0>2 |V 82>3| A 0>1 | V? * CR
First switch all Audio a nd video outputs from inp ut 1,
Then switch video input 3 to output 4, video input 2 to output
2, video input and disconnect video output 2.
Then switch audio input 3 to output 2,
Then disconnect audio output 1.
Then get status of all links (assume this is 4x4 matrix).
Commands processing start after entering CR, response will sent
for each command after processing it.
