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!

IR input direct on some AV devices my need to have the carrier stripped. Some implementation like the RFX9600 offer a solution by adjusting the IR power level.

Another very common issue with IR Input direct is that some AV equipment manufacturer use INVERTED IR encoding on their IR direct input ports.

Some PIONEER rear projection screens for example use Inverted IR encoding for IR – Direct versus IR over EMITTER.

We should make a request to add options in Pronto Editor for “NO CARRIER” in those cases where CARRIER can saturate the manufactures direct IR-INPUT optical circuits. Most manufactures are not even specifying this or are not aware of this technical detail.

However these two options
a)NO Carrier
b)Inverted encoding

Should be made available by the TSU9600 pronto editor and RFX9600 and RFX9400 extender. It is a common feature in most high end automation systems.

For the short term you may want to adjust the output level with the dip switches on the back of the RFX9600 to avoid the optical saturation. I hope it will work for you.

Great advice. I don't think the Pronto editor offers this level of customization in terms of inverting the encoding, but I just got off the phone with Escient tech support and they suggested reversing the polarity of the serial IR cable. They say they've seen similar issues with Elan home control systems and that flipping the two wires in the IR cable solves the problem. I'll give it a try soon and let everyone know if it works.

As to adjusting the output level, I've tried this to no avail :(

Thanks for the advice!
