6.3. A/V Port Settings
6.3.1. Switch an Input to the Output
Following commands with <A/V/AV> option can take effect in multiple layers, according to their 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, the devices change all
(Video & Audio) layers but using status commands it displays information about only the Video layer.
Please use AV option, when available.
Description: Switch input <in> to output <out>.
Format
Command {<in>@<out>●<layer>}
Response (O<out²>●I<in²>●<layer>)CrLf
Explanation: I2 audio and I2 video input ports are switched to O1 output port.
Legend:
<layer>
AV (or nothing)
<out>:
<in>:
ATTENTION! The response of this command does not show if the output is muted. To check the mute
status a separate query has to be used like {VC}.
ATTENTION! Analog video inputs does not contain embedded audio. If you use the AV option in case of
VGA input (I1) the audio will be switched to the analog audio input 1 (I1) and in case of DVI-A input (I5) the
audio will be switched to the analog audio input 2 (I5).
6.3.2. Mute Output
Description: Mute output <out>. The output signal is turned off.
Format
Command {#<out>●<layer>}
Response (1MT<out²>●<layer>)CrLf
Explanation: O1 audio port is muted.
ATTENTION! Muting does not change the crosspoint's state but disables the output itself. This way the
last connection can be easily restored with an unmute command. Switching a muted output does not
unmute the output.
Example
 {2@1 AV}
 (O01 I02 AV)
Layer
A Audio layer
V Video layer
Audio & Video layer
O1 output port.
I1...I6 input ports.
Example
 {#01 A}
 (1MT01 A)

6.3.3. Unmute Output
Description: Unmute output <out>.
Format
Command {+<out>●<layer>}
Response (0MT<out²>●<layer>)CrLf
Explanation: O1 video port is unmuted.
INFO: Unmuting an output makes the previous connection active as the crosspoint state has not been
changed by the muting command, only the output was disabled.
6.3.4. Lock Output
Description: Lock an output port. Output's state cannot be changed until unlocking.
Format
Command {#><out>●<layer>}
Response (1LO<out²>●<layer>)CrLf
Explanation: O1 audio output port is locked.
6.3.5. Unlock Output
Description: Unlock an output port. The connection on output can be changed.
Format
Command {+<<out>●<layer>}
Response (0LO<out²>●<layer>)CrLf
Explanation: O1 video output port is unlocked.
INFO: The device issues the above response regardless of the previous state of the output (either it was
locked or unlocked).
Example
 {+01 V}
 (0MT01 V)
Example
 {#>01 A}
 (1LO01 A)
Example
 {+<01 V}
 (0LO01 V)
