The Gpio Port - Christie CP2000-ZX User Manual

Appendix C: GPIO
C.1 The GPIO Port
The 37-pin GPIO connector is located on Auxiliary panel next to the main communication panel on the
operator's side of the projector. It provides a flexible method of interfacing a wide range of external I/O
devices to the projector, often so that an event on one device automatically triggers an event on the other. The
pins that are configurable on this connector are done through the Advanced: 3D Control menu.
NOTE: Pins not shown in the figure below are reserved for other uses and cannot be specified.

As shown above, each available pairing of pins (+/–) is defined as either an input or output. Configure a pin as
an input if you want the projector to respond to an incoming signal, or as an output if you want an external
device to respond to the projector. For example, configure the pin as an output in order to drive an external IR
emitter for 3D glasses, or to automatically reduce room lighting when the projector is turned on.
If you are wiring your own GPIO cable for use with a server or 3D device such as an IR emitter or a polarizer,
follow the circuit diagram Figure C-1, above.
