Hi all,

I have a Philips TSU9200 and the RFX9200 RF extender. The extender has 4 IR outputs (3.5mm mono) and comes with 4 emitters.

I have a Key Digital switcher with a serial IR input. I thought I could just hook up a mono phono cable from the emitter jack to the switcher's IR in (& use the emitter elsewhere), but it doesn't work.

Do I need to get special IR cables, or is there a problem with the IR in on my switcher? Product links would be helpful...

Thanks.
