Title: SR227 modules turn on, but not off.
Post by: Thomas351 on February 27, 2006, 12:40:35 AM

Okay, I think I figured it out, but maybe someone could verify.

Using a SR227 receptacle module to control the home-stereo. Into that I have a surge supressor strip, and into that is the various components of the stereo.

With the system wired as described, it will turn on, nut not off. If I plug the stereo into the wall outlet without the surge-strip, I can control it. If I plug the surge-strip with stereo into an extension cord, then plug the cord into the module, it works.

In other words, it seems to be the surge suppressor is filtering the X10 signals, even thou it's downstream of the socket? YEah, nea?

Thanks,
TC

Yes the surge suppressor is sucking up the X10 signals. When the outlet is off the strip is not on the powerline and doesn't suck up the signals. When the outlet is on the strip sucks up the signals and you can't turn it off. One solution to keep the strip would be get an X10 type filter [blocks the absorbtion of X10 bad signals] and plug it into the outlet then the strip and stereo into the filter.
Figure your power needed and get an X10 filter. I know X10Pro makes a 5 amp one and other manufacturers make 10 and 15 amp ones. My APC BX1000 UPS sucked up so much X10 signals I had to add a 10 amp filter to it's AC Input to get anything to work.

Good Evening,

A interesting problem to say the least.  Once you understand what is happening it is simple.  With the module off it can receive the X10 signal without a problem.  When the module is on, it connects a good attenuator on the line which adsorbs most if not all of the x10 signal.  Turn it off ant the attenuation is gone.  I bet this also effects other modules in your system as well.

The attenuation could be caused by the surge suppressor,the stereo or anything else connected to the strip.  Unplug them then plug one at a time until the problem returns, you then know which unit is causing the problem.  It is possible more then one problem is connected.  Remember the plug strip is also a component.

Good Luck
