Do the NIRT plates accept industry standard IR emitters ?? I have tried about a dozen different types, none are working. I am currently trying to test the IR codes, via CIRC, using the test command option, while connected to the NIRT via the High Speed serial cable. Yet, cant get the IR emitters to flash, or any of my codes to work. Anything I'm missing. ??? Do I need to use the C-Bus Ir emitter. ??
