We recommend using the UC 50’ universal projector control cable (included with the System 7SC) 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 System 7’s projector control port pins.

Two categories of projector control files are sent via this port: RS1 and RS2. Both types make it possible to control a projector’s power, mute, and input selection functions.

RS1 files are for unidirectional (talk only) communication from the switcher to the projector. RS1 requires only wiring the ground pins, the switcher’s transmit pin, and the projector’s receive pin. Refer to the following table and to the projector’s manual for wiring instructions.

RS1 (unidirectional communications) wiring —

used with user-defined and RS1 Extron files

Pin	RS-232	RS-422
I	n/a	Transmit - (Tx-)
E	Ground	Ground
C	Transmit (Tx)	Transmit + (Tx+)

NOTE Each projector/display may require different wiring. For details, refer to the manual that came with the projector.

RS2 files are for bidirectional (talk and listen) communications between the switcher and projector. Transmit, ground, and receive pins must be wired for RS2 communications. Except for the ground connection, RS2 wiring is projector-specific. Refer to the projector’s manual for details or call the Extron S3 Sales and Technical Support Hotline if needed.

7RS-232 port — This connector provides for two-way RS-232 communication. See the “Serial Communication” chapter for information on how to install and use the control software and SIS commands.
