System Integration - Gpio Connector - Christie Entero RPMSP–LED01 Installation Manual

3.9 System Integration – GPIO Connector
The General Purpose Input Output (GPIO) connector located on the input panel provides a flexible method of
interfacing external I/O devices to the projector. There are 7 GIO pins on the 9–pin D–Sub GPIO connector,
which are configured via RS232 commands. The other 2 pins are reserved for ground, and power. The cable
required for connecting the external device to the projector GPIO connector, whether it is 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 GIO serial command code.
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 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 powered 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. See (GIO) General Purpose Input/Output in the Entero RPMWU/RPMSP/
RPMHD–LED01 User Manual (P/N: 020-100367-xx).
