Ok, so I can not control any light modules, camera power supplies...etc... other than the room I have my CM15A plugged in at. So I ran an extension cord all the way down stairs and into the garage....and PRESTO.....now I can control modules in every room . So I thought....ok, all the other rooms are on a different phase. So I purchased and installed the plug in Signal Coupler (Model 4816A2) from SMARTHOME, it is plugged in at my dryer.
Nothing...........I still have the same problem!!!
So now what?! I know there is the wireless USB extender, which is what I am leaning towards right now......do I have any other options?
jsnone1,
It's unlikely that
all of your room circuits are on the opposite phase from your CM15a. Additionally, the fact that bridging the phases with the Signalinc and the 240V dryer did not improve communication implies that you have a signal absorber or noise source between the CM15a and your units.
Prior to adding more hardware, do a bit of inspection to determine which phases your devices are on and where possible problem devices may be. The schematic below was posted as part of Jeff Volps tutorial on couplers and repeaters. It shows the phase connections used by
most panels. Working down the left side of the panel, adjacent breakers are on opposite phases (circuit 1 and 3). Circuits 1 and 5 are on the same phase.
Once you have determined where your X10 devices are located, try moving your CM15a around to different breakers within the house. Also try disabling breakers with suspect loads (PC's, TV's/Stereo, etc) to see if performance improves. If you do see and improvement, you'll need to start unplugging devices to see which is the offender (noise/absorption). Offenders are candidates for noise filters.
In the end you may still require a coupler or repeater. However, mapping your circuits and tracking down offenders while your system is in a "simple state" will pay dividends down the road.
Jeff Volps tutorial on couplers/repeaters is located here:
Passive Couplers and Repeaters. It is by far the best presentation that I have seen regarding phase coupling (
