Appendix C: GPIO
As shown in Table C.1, each available pin pairing (±) is either an input or output. Use an output to drive an
external IR emitter for 3D glasses, or to automatically reduce room lighting when the projector is turned
ON.When wiring a GPIO cable for use with a server or 3D device, such as an IR emitter or a polarizer, follow
the circuit diagram illustrated in Figure C-2.
