I was wondering if the remote itself does both IR and RF or only RF and then converts the RF to IR through the repeater. I can explain why, my new system will be a Samsung UN55B8000 which has RF, a Bell PVR which has RF and a YSP-4000 which has IR. With this set-up there is no need for repeater as the YSP-4000 will be in plain sight. Thanks.

Yes the 900 can do both IR and RF. It is all in the set up. Once you have programmed the remote it then goes through the RF setup and allows you to select which devices will be using what function (*NOTE* when using RF the remote sends codes to an RF receiver which transfers the signal back to IR).

Most of the time I have all the devices but the TV using RF as they are in a cabinet or some where that is not by the TV. Most people tend to point a remote at the TV when they are using it so there is no real need to set it up to RF, as well as the added pain in trying to get one of the 2 IR blasters in front of the TV.

Hope this helps

Cheers,

The Harmony 900 will not be able to control your RF devices unless they use Z-wave RF, or have provision for IR control. The 900 uses the Z-wave RF protocol to control its own RF to IR repeater and Z-Wave devices. It's against FCC and Canadian rules for one Mfg to use another Mfg RF frequency unless the use an accepted RF protocol like Z-Wave, Bluetooth, etc.
