Appendix C: System Integration
C.1 Introduction
The GPIO connector located on the side input panel provides a flexible method of interfacing a wide range of
external I/O devices to the projector, usually so that an event on one device automatically triggers an event on
the other. There are 7 GIO pins available on the 9pin D-Sub GPIO connector, which are configurable via RS-
232 commands. The other two pins are reserved for ground and power. The table below provides 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.
C.1.1 Configuring the GPIO
The GPIO connector is most easily configured with the KoRe 10-bit Librarian software. The
RTE
tab within
the KoRe 10-bit Librarian user interface provides a graphical Helper to aid in the setup of the GPIO. In
addition, Real-Time events can be used to trigger different GPIO output states when certain events occur.
Refer to
KoReLibrarian
and the
Serial Protocol manual
for more details.
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 an 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.
A
GIO
command 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.
