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 illustration below shows the pin assignments of the MLC’s control connector that are covered in detail on the following pages.

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.
