Rly1Mode*
X?
Cause a button to control a relay.
For a relay set to be normally closed
:
0 = power-on.
1 = power-off.
2-7 = MLC input selection buttons 1-6.
8-27 = remote control module 1 buttons.
28-47 = remote control module 2 buttons.
48-67 = remote control module 3 buttons.
68-87 = remote control module 4 buttons.
For a relay set to be normally open,
add 128 to the above numbers.
128 = power-on (relay normally open).
...
196-215 = remote control module 4
buttons (relay normally open).
127 or 255 = not assigned.
