RS-232 Display/Source Control connector
— The MLC sends out RS-232
commands via this port for controlling a projector or a slaved Extron system
switcher. Guides for slaving system switchers to the MLC and for controlling
specific models of projectors are available on the Extron Web site.
Connect a cable between the projector and this 3.5 mm, 5-pole direct insertion
captive screw connector for RS-232 projector control. Use the illustration
below as a guide to wiring the connector. Wiring will vary depending on the
projector model. In most cases only the transmit (Tx) and ground connections
will be needed.

We recommend 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’ pin assignments
are as shown in the following illustration. Refer to the projector’s manual for
the projector’s pin assignments in order to determine which of the cable’s
wires to connect to which of the MLC’s RS-232 pins.
