Unidirectional Control and Communication Connections

IR/Serial output ports — An IPCP 505 can use infrared signals or unidirectional
RS-232 serial signals to control various devices (up to 32 total for IR) via these eight
ports. Set output signal type (IR or serial) during configuration. The figure below shows
wiring examples.

Figure 10. 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 serial protocol options
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 figures or the IR Emitter Installation Guide.
NOTE: Each emitter must be within 100 feet of the IPCP for best IR control results.
