IR/Serial output ports (see
through page 20) — An IPCP Pro Series control processor can use infrared signals or
unidirectional RS-232 serial signals to control various devices (up to four per port for IR)
via these ports. Set output signal type (IR or serial) during configuration. The following
figure shows wiring examples.

Figure 24. Wiring the IR/Serial Ports
Serial control — Connect one of these ports to the serial control receive (Rx) and
ground pins of the device to be controlled. These ports have the same
options (see page 23) as the COM ports.
IR control — Connect one of these ports directly to the wired IR port of another device.
Alternatively, insert the wires from up to four IR Emitters into an IR port and place the
heads of the emitters over or next to the IR signal pickup windows of the devices. For
wiring, see the following diagrams or the IR Emitter Installation Guide (available on
www.extron.com).
NOTE: Each emitter must be within 100 feet (30.4 meters) of the IPCP for best IR
control results.
