Technically, I believe that you are correct. I apologize, as I was probably using incorrect terminology in this case.
The device I am referring to came shipped with my Harmony 890. They refer to this as a "Wireless A/V bridge receiver."
To quote from their description, this small device "serves as a bridge receiver which converts RF signals to IR commands, for control without a direct line of sight!"
If no RF signal is needed, it merely picks up the the IR signal from your remote, and then can beam it again to any device which has direct line of sight, using normal IR technology.
The device has an AC cord attached to it. You plug this cord into the nearest electric outlet, and that is all. In my case, no other cords or cabling or wiring is involved. I aim my remote from my seat to the front of the theater. This device is sitting on top of my equipment rack, plugged into an AC outlet on the equipment rack. This device then simply "repeats" the same code, only it is now re-beaming it toward the back of the room, behind me, where my dimmer is. The dimmer receives this code (which is the same code as the ones that would normally be sent by its own native remote that comes in the package.) The dimmer responds accordingly.
Hope this is clear.
If you wish to see the small "Wireless A/V bridge receiver" that comes with the Harmony 890, here is a link. Scroll down and look for a square box with a "Number 4" as its label.http://www.logitech.com/index.cfm/pr...ONTENTID=10930
