IR/Serial output ports — 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
figure below shows wiring examples.

Figure 13. 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
(see page 15) as the COM ports.
IR control: Connect one of these ports directly to the wired IR port of another device.
Or 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 of the IPCP for best IR control results.
