Projector control port — Connect a cable between the projector and this
3.5 mm, 10-pole captive screw connector for RS-232 or RS-422 one- or two-
way projector/display device control. Commands from a downloaded
projector control program or user-defined command strings entered via the
Windows-based control program can be sent to the display device from this
port.
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.
