The CM15A requires an electrical modification to disable the RF Receiver. Simply turning off a housecode in the transceive table will not prevent the RF signal from triggering a macro.
Wow, I didn't know that!
So, the transceiver table within AHP will just enable/disable the CM15a from passing onto the power line the RF commands, but the CM15a itself will still "see" and react to all RF commands ?? ?? ?? ??

That is correct ...often confusing and misunderstood, but correct.
Allow me to confuse this thread by saying that this is
correct in most cases. I believe the true answer depends on the firmware revision of your CM15a.
I have 2 newer CM15a's which both respond exactly as Puck has stated (disabling the Transceived house code will prevent the CM15a from putting information on the power line but It will still activated macro's).
- Unit 2 - '06 model, firmware revision M
- Unit 3 - '07 model, firmware unknown (I'm still checking it out prior to voiding my warranty).
My "old" unit responds differently. With a transceived house code disabled, it sees the RF (logs in activity monitor) but it
will not trigger macros or put info on the power line. I've just verified this again minutes ago - there is no power line or macro activity in activity monitor. I also check the power line with a testerlinc - nothing transmitted.
- Unit 1 - '04 model, firmware revision E
I've been slowly comparing the reactions of my various interfaces - there are quite a few differences between the units. As some point I'll try to quantify these differences based on the Firmware revision of the hardware. If you're interested in contributing, TTA has placed a Sticky in the Software bugs thread.
I've become a little concerned that some of our
"newbies" may actually be using old hardware (new to the site doesn't necessarily mean new to X10). If so, we could be leading them down the wrong path and frustrating them further.
Walt - you've been a member for awhile. You may want to test your CM15a to see how it responds.
