6.4.2. Mute 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.
6.4.3. Unmute 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. Lock Output
Locking an output port. Output's state cannot be changed until unlocking.
Command and Response
 {#><out>•<layer>}
 (1LO<out²>•<layer>)CrLf
Example
 {#>01 A}
 (1LO01 A)
#unmute #unlock
