A Maxi Controller is normally used for XTBR / XTB-IIR mode programming. Some people have asked how to do mode programming with a CM15A or CM11A. One of my customers wrote a nifty utility to do that, and I've sent it to anyone who asked for it.
The 1.20 XTB-IIR firmware update last fall added several new mode options, including the ability to inhibit repeating certain housecodes. That can prevent command ping-pong in installations where more than one repeater is powered by the same utility transformer.
I updated the utility to support all new mode options except for the ability to query the AGC detection threshold. (The X10 SDK does not support reading preset dim commands.) A beta version of the utility is available by sending me a private request. Also let me know which version firmware you have.
