7.4.1.
Switch One Input to One Output
Switching an input
<in>
to output
<out>
. Following commands with A, V, AV parameter value 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.

Parameters
Identifier
Parameter description
Parameter values
<layer>
Signal type of the layer
A:
audio layer
V:
video layer
AV:
audio & video layer
<out>
Output port
O1-O4 (or O8)
<in>
Input port
I1-I8
0:
Using the '0' (zero) value the input will be
disconnected and no signal will appear on the output
INFO:
The
<layer>
parameter 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.
Example 1
{2@1 AV}
(O01 I02 AV)
I2 audio and I2 video input ports are switched to O1 output port.
Example 2
{0@1}
(O01 I00)
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}. See
View Connection State on the Output
section. To
achieve multiple switches executed together, see
section.
7.4.2.
Switch One Input to All Output
Switch input <in> to all outputs.
Command and Response
{
<in>
@O}

<in2>
•
ALL
)CrLf
Example
{2@O}
(I02 ALL)
7.4.3. Mute Specified Output
Mute the
<out>
output. The output signal is turned off.
Command and Response
#mute #lock
{#
<out>
•
<layer>
}
(1MT
<out2>
•
<layer>
)CrLf
Example
{#01 A}
(1MT01 A)
ATTENTION!
Muting does not change the state of the crosspoint 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.
7.4.4. Unmute Specified Output
Unmute the
<out>
output.
#unmute
#unlock
Command and Response
{+
<out>
•
<layer>
}
(0MT
<out2>
•
<layer>
)CrLf
Example
{+01 V}
(0MT01 V)
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.
