The Gpio Port; D.1.1 Example: Gpio And 3D Device - Christie CP2000-SB User Manual

Section 1: Introduction
D.1 The GPIO Port
The 37-pin GPIO connector is located on the Source and Communication Panel located on the underside of the
projection head near the front. 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 on
this connector that are configurable using the TPC's Custom 3D Control menu are identified in Figure D-1.
NOTES: 1) Pins not shown in Figure D-1 are reserved for other uses, and cannot be specified at the TPC. 2)
Cable access is through the pedestal "toe" at front.
As shown above, each available pairing of pins (+/–) is defined as either an input or output.
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 in Figure D-2.

D.1.1 Example: GPIO and 3D Device

1. Assemble a cable according to guidelines shown in Figure D-1 and Figure D-2.
2. Connect the cable to projector's GPIO port and to your 3D device.
3. In the TPC's Custom 3D Control menu, set Output GPO according to the pins wired in the GPIO cable
(see Figure D-1). For instance, if you have wired pins #10 (+) and #29 (-) to your 3D device, set Output
GPO to GPO #2.
