6.4.1. Switching an Input to the Outputs
Switching an input
<in>
to output <out>. The 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.
Command and Response
{<in>@<out>•<layer>}
(O<out2>•I<in2>•<layer>)CrLf
Parameters
Parameter
Parameter description Value
<layer>
Signal type of the layer
<out>
Output port
<in>
Input port
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 the 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}.
#crosspoint
#switch
Value description
audio layer
A
video layer
V
audio & video layer
AV
O1..O2
I1..I4
Using the '0' (zero) value, the input will be disconnected and
0
no signal will appear on the output.

MMX4x2 series – User's Manual
6.4.2. Muting an Output
Mute the
<out>
output. The output signal is turned off.
Command and Response
{#<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.
6.4.3. Unmuting an Output
Unmute the
<out>
output.
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.
6.4.4. Locking an Output
Locking an output port. The output's state cannot be changed until unlocking.
Command and Response
{#><out>•<layer>}
(1LO<out²>•<layer>)CrLf
Example
{#>01 A}
(1LO01 A)
#mute #lock
#unmute
#unlock
