Attach cables to the control connector on the MLC 52 rear panel .
The ports in this connector, from left to right, perform the following functions:
F (Tx) — Transmits the RS-232 signal for projector control.
This port is present on all models, but it is active only on the RS models.
E (IR OUT) — Used for connecting an IR Emitter to issue IR commands. Up to two
emitters can be wired to this port. There is a maximum of 100' wiring
distance from the port to the emitter.
D (GND) — Ground for IR and/or RS-232 projector control
C (IR IN) — Used for connecting an optional IR Link or IRL 20, so that the IR 452
remote can control the MLC.
B (GND) — Ground for the +12 VDC power
A (+12V) — Power input for the product (12 VDC)
