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.
To a Projector,
Panel Display, or the IR or RS-232
Wired IR Remote or
RS-232 Port of a
Source Device
Figure 9.
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
(see page 17) as the COM ports.
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.
