Display control and power connector
— This six-pole, 3.5 mm captive screw
connector is used for IR and RS-232 control of the projector and for DC power.
(See
Wiring the control connector
, in the next section, for information on how to
connect supported devices to this connector.)
The RS-232 projector control port is present but not functional on the IR
models. This port is functional only on the RS models.
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.

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. There is a maximum of 50' 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 an IR
remote can control the MLC.
B (GND)
—
Ground for the +12 VDC power
A (+12V)
— 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.
