Connecting to the GPIO connector
The GPIO connector located on the input panel provides a flexible method of interfacing a wide
range of external I/O devices to the projector. Seven GPIO pins are available on the 9 pin D-Sub
GPIO connector, which are configurable with RS232 commands. The other two pins are reserved for
ground and power—see the table below for pin identification.
The serial cable required for connecting the external device to the projector’s GPIO connector must
be compatible with the external device.
