It does indeed work, im using a TM12U x10 rf receiver and am able to control the x10 devices using the codes produced by CodeGen's X10/Pronto generation (FWIW i know the TM13U works also).

All I had to do was set the device on the 950 to RF instead of IR and to select channel 0 and ID 0 as Raptor suggested.

At present I have been unable to find a way to enter X10 codes from the handset, I am currently using preset buttons for on and off (eg. a button for A1 on, another for A2 off, etc.).

Hope that helps.
