The GPIO port is a 37-pin D-sub connector (female) located on the PIB input panel and provides 8 input and 7
output signals for connecting external devices to the cinema projector. To configure the pins on the connector,

.
As shown below, each available pairing of pins (+/–) is defined as either an
input
or
output
. Four inputs and
three outputs have already been predefined. Configure a pin as an input if you want the cinema projector to
respond to an incoming signal, or as an output if you want an external device to respond to the cinema
projector.
