The GPIO (General Purpose Input Output) connector located on the input panel provides a flexible
method of interfacing a wide range of external I/O devices to the projector. There are seven GIO pins
available on the nine-pin D-Sub GPIO connector, which are configurable via RS232 commands. The
other two pins are reserved for ground and power – see table below for pin identification.
The serial cable required for connecting the external device to the projector's GPIO connector,
whether it's a standard serial cable or a custom one, must be compatible with the external device.

The GPIO connector can be configured to automate any number of events using the serial
command code GIO. Each pin is defined as either an input or output depending on the
desired outcome. In general, configure the pin as an input if you want the projector to respond
to something the external device does and as an output if you want the external device to
respond to an action taken by the projector. For example, configure the pin as an output if you
want the lighting in a room to automatically dim when the projector is turned on.
By using the GIO command, you can also set the state of each pin as high or low. By default,
the state of each pin is high. The voltage applied to pins in the high state is + 3.3V.
Example 1. Turn room lighting on when the projector is turned off. (Assumes a
control/automation unit is configured to turn the lights on when pin 2 of its input goes high.)
