Has anybody been successful using a TSU7000 thru an RF Extender (RFX6000/01) to control an ATT VIP1200?

Initially had problems learning the codes, but was successful learning to a older TS1000 and copying the hex codes over. The remote seems to work using IR, but the RF receiver doesn't see the RF transmissions. The light on the 6000 doesn't flash when a button is pressed. (It does flash for other devices, and I HAVE enabled RF and set the Channel and ID values.)

Thanks for any help.

Edit -- Nevermind, I figured it out. The IR codes are stored under a hidden device called "IR Codes" that contains IR codes only, no user I/F, one device per page. THAT device had the RF turned off.
