Command Description Response
LCK: - AES/EBU PLL Lock status Request
Response depends on model type:
RM-2S4 responds: LCK:x
Where: x = lock status of selected stereo source. No further lock
information is available.
RM-2S10 responds: LCK:x+yyyyyyyyyy
Where: x = lock status of selected stereo source.
y = lock status of all ten AES inputs.
RM-4C8 responds: LCK:xy+zzzz
Where: x = lock status of left selected mono source.
y = lock status of right selected mono source.
z = lock status of four mono sources in currently selected bank.
No lock data is available for an unselected bank.
LCK:ab - Set GPIO lock output logic preferences ACK:
a = 0 selects normal polarity (lock = low/conducting
output).
a = 1 selects inverted polarity (lock = high/non-conducting
output).
b = 0 selects the logical OR of the LH & RH channel
lock status.
b = 1 selects the logical AND of the LH & RH channel
lock status.
MOD:x,y - Remote control of audio Modiers ACK:
Where: x = modier number, 0 to A (hex - values B to F accepted
but have no eect).
y = 0 to turn modier o.
y = 1 to turn modier on (hex values 1 to F accepted and have
same eect as 1).
The modier numbers are:
0 = DIM, 1 = CUT L, 2 = CUT R, 5 = MONO, 6 = PHASE INVERT and
7 = M+S
OPT:x,yy - Set technical options ACK:
x = option number (1…F in hex)
yy = new value for option parameter (00…FF in hex)
All OPT settings are stored in non-volatile memory and retained
during power loss.
OPT:1,xx -Turn o presence detection: ACK:
Where: x = 00 enables the presence detectors (default setting).
x = 01 disables the presence detectors (hex values 01 to FF
accepted and have same eect as 01).
