7.4.5. Lock the Output
Locking an output port. Output's state cannot be changed until unlocking.
Command and Response

 (1LO<out2>•<layer>)CrLf
Example
 {#>01 A}
 (1LO01 A)
7.4.6. Unlock the Output
Unlocking an output port. The connection on output can be changed.
Command and Response
 {+<<out>•<layer>}
 (0LO<out2>•<layer>)CrLf
Example
 {+<01 V}
 (0LO01 V)
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).
7.4.7. View Connection State on the Output
Viewing the output's connection results in different response length, because it depends on the device. The
response below refers to an MMX8x4-HT420M.
Command and Response #crosspoint
 {VC•<layer>}
 (ALL<layer>•<O01>•<O02>)CrLf
Parameters
O01 shows the corresponding output's connection state.
Identifier Parameter description

Command and Response
 {getsize•<layer>}
 (SIZE=<size>•<layer>)CrLf
Parameters
Identifier Parameter description

<layer> Signal type of the layer
Example
 {GETSIZE }
 (SIZE=8x5)
INFO:
In MMX8x4-HT400MC and MMX8x4-HT420M models five outputs means four video and one
