Denon AVR-2112CI Control with Xantech 28EXT External Emitter Adapter

I am using a Xantek MicroLink IR Receiver Kit (ML85K) to control my Motorola set top box (QIP7000 series or specifically QIP7216). In addition to using the kit included model 789-44 connecting block I had to purchase the Xantech model 28EXT External Emitter Adapter and use the "Wire Swap Connector".

I am now interested in controlling my new Denon AVR-2112CI using the "IR IN" female connector on the back of the unit. My question is two fold, can I use the 28EXT External Emitter Adapter to accomplish this, and if so do I use the "Wire-Swap Connector" with the 28EXT to control the Denon AVR-2112CI? My understanding is that the "Wire-Swap Connector" "Swaps the Tip and Ring" on the 3-Conductor male plug. Stating the question in another way, "Should the Tip be the Signal (28EXT without Wire Swap Connector) or should the Tip be +5VDC power (28EXT with Wire Swap Connector) to control the Denon AVR-2112CI ?

I would simply try it, but there are warnings regarding possible device damage if improperly connected.

Thanks for the help!

OK, I investigated this issue further with Denon USA, but really didn't get much help with them when it came to hooking the IR input up to my Xantech system. However, a follow up call to Xantech's technical support was very helpful. They informed me that a Xantech 28EXT purchase is not required for the Denon AVR-2112CI. The Denon unit only requires a 3.5mm (mini) mono male to male cable from the Xantech 789-44 output to the IR Input on the Denon. It works perfectly!

I hope this post helps someone with their Motorola set top box or Denon AVR hook up in the future.
