Wiring for RS-232 control (RS models only)
The MLC 52 RS and the MLC 52 RS VC send out RS-232 commands via the Tx port
for controlling a display device.
If you have an RS model and want to control the device via RS-232, connect a cable
between the device and this 3.5 mm, 6-pole direct insertion captive screw
connector. Use the illustration below as a guide to wiring the connector. Wiring
varies depending on the device model. In most cases, only the transmit (Tx) and
ground connections are needed.
Guides for connecting and controlling specific models of devices are available on
the Extron Web site.

Wiring for RS-232 control (RS models only)
Extron recommends using the UC 50' universal projector control cable for this
connection. One end of the cable is terminated with a female 9-pin D connector,
and the other end is unterminated. The UC 50' cable pin assignments are as shown
in the following illustration.
Refer to the display device user’s manual for the device’s pin assignments in order
to determine which of the cable’s wires to connect to the MLC’s RS-232 pins.

Wiring an IR Link
An optional IR Link or IRL 20 can be connected to the IR In pole of the control
connector to enable the MLC to receive IR signals from the IR 452.
Only one IR Link or one IRL 20 can be attached to the MLC 52 at one time.
To wire the IR Link for use with your MLC,
1. Prepare the site where the IR Link will be installed and install a wall box,
following the directions in the IR Link User’s Manual, provided with your
IR Link equipment.
2. Cut the required length of Extron CTL (Comm-Link) cable to go between the
MLC 52 and the IR Link. The power cable length should not exceed 150'
(45.7 m).
