It doesn't handle X-10 type codes, uses a different RF frequency and would
require custom software on the PC to use it for anything other than what the
ATI software does. I was merely pointing out that it is made by X-10.

I don't care whether they resell them or not. In the case of the one
recently offered for sale I merely noted that the seller got it for free and
complained incessantly that he couldn't make it work. In other words, caveat
emptor. Jeff tells me the surplus bare boards are going fast.

If you use them with CM11As they won't collide. If you use them with
Ocelot/TW523, they will. The simplest arrangement is BX24-AHT+CM11A on one
phase and any standard transceiver on the other. The CM11A will back off
when it senses a collision and let the other transceiver send its PLC code.
