I am able to control devices through IR just fine through my RFX9600 when using the sticky red IR emitters on the front of my equipment, however I can't for the life of me seem to get the IR connections to work when connected from the RFX9600 directly into my 'IR in' inputs. I've tried everything I can think of, so I figured I would ask for some help here.

I am able to control the devices fine when using the sticky red pads, so I know that the TSU9600 is sending the right commands and that the RFX9600 is working correctly. I've tried setting the RFX to both low- and high-power but didn't see any change in results. I've tried using both the IR-IR cables that came with the RFX and also Tributaries trigger cables, however none of them seemed to work.

The devices I'm trying to control here are a Denon DVD-2930CI and an Escient MX-111.

Any suggestions on anything I can try? I'd really appreciate any advice anyone can offer. Thanks in advance!
