IRX-RX Port: Connection and Wiring

The NI-700 and NI-900 units both have a single rear 4-pin IR receiver port (IR RX).

The IR RX port functions using AMX IR codes (38 KHz and 455 KHz) and works ONLY with AMX IR Receivers such as the IRX-DM+ and IRX-SM+.

This port can be used to connect one or more (8 maximum in parallel) optional IRX-SM+ or IRX-DM+ Decora mount IR receivers to the Integrated Controller as shown in FIG. 6.
