Describing the IR Modulator/Demodulator
The IRD is bidirectional and is designed to be part of a chain of signal transmission where an IR signal must be modulated or demodulated to accommodate devices that require either a modulated or a
demodulated signal, such as, the TP-574, TP-573, or a Kramer RC series room controller.
The IRD is powered externally by a compatible device, for example, the TP-573. Power is received via the female, 3.5mm mini jack socket on the IRD.
Connecting the IR Modulator/Demodulator
The IRD can be connected as shown in Figure 1.

Modifying a Cable to Connect to a Room Controller
Connecting to a Room Controller with a terminal block connection requires a custom cable.
To connect to a Room Controller using the IRD:
1. Cut the male 3.5mm mini jack connector from a C-A35M/A35F cable.
2. Separate the two wires and strip approximately 7mm of insulation from the two wires.
3. Connect the wire with the stripe to the IROUT terminal block on the Room Controller.
4. Connect the wire with no stripe to the GND terminal block on the Room Controller.
