Unidirectional Control and Communication Connections

IR/Serial output ports
An IPL EXP 200 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.

Serial control — Connect the IR/S port to the serial control receive (Rx) and ground pins of the device to be
controlled. These ports have the same
IR control — Connect the IR/S port 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 EXP for best IR control results.
