Installation Guide
AT-HDR-EX-100CEA-KIT
The AT-HDR-EX-100CE-KIT provides both an RS-232 and IR port. RS-232 pass-through is
supported, allowing a control system to be connected to either the transmitter or receiver.
Connect the included IR emitter to the transmitter and an IR extender (not included) to the
receiver. Both IR and RS-232 connections are optional.
1. Use wire strippers to remove at least 3/16” (5 mm) of the cable jacket for both the RS-232
and IR emitter.
2. Insert the wires as shown into the included 5-pin captive screw connector.
NOTE: Typical DB9 connectors use pin 2 for TX, pin 3 for RX, and pin 5 for
ground. On some devices functions of pins 2 and 3 are reversed. Also note, that
IR is bidirectional, allowing the IR emitter or IR receiver to be connected to either
the transmitter or receiver.
