Wiring the control connector
The display and source control connector allows you to connect cables for IR
devices, RS-232 devices (RS models only), and AC power to the MLC. The

Pinout guide for the MLC 52 display/source control connector
The ports in this connector, from left to right, perform the following functions:
F (Tx) — Transmits the RS-232 signal for projector control.
Although this port is present on both the IR and the RS models, it is functional
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.
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 an IR remote
can control the MLC.
B (GND) — Ground for the +12 VDC power
A (+12 V) — Power input for the product (12 VDC)
The two-gang MLC 52 IR VC and MLC 52 RS VC have the same control
ports as the one-gang models.
