Inexpensive X10 Test Equipment

There comes a  time when you may need need to troubleshoot an X10 system.  You know the situation. Something doesn’t turn on, and you can’t figure out if you’ve got a bogus transmitter or a bum receiver. Hmmm, how do you isolate the problem to either device? Well, you could go all out and purchase the best X10 powerline signal analyzer known to mankind and get the MIPLSA.  With its LCD display, this baby will show you the signal strength, noise level if any, the actual signal house and unit code, and it will even record powerline activity over a period of time.  Too costly? Yeah, I thought  so.

Dropping down in altitude, there’s the XPXPTR. Instead of an LCD display, you have LED indicators to show the signal and noise levels. Obviously, you won’t see house and unit code information, but that’s OK, right?  Nor will you have the ability to record.

Now we get to the budget X10 test equipment. Actually, you’ll be creating your own test equipment.  Get yourself the XPPHC02 Maxi-Controller transmitter AND the XPPHH02 Chime Module receiver.  Use this as your reference  transmitter/receiver pair, allowing you to send and receive all 256 X10 addresses.  Set the Maxi-Controller and Chime Module to the same address code to verify proper operation. The chime will produce a pleasant “ding-dong, ding-dong, ding-ding” sound after receiving an ON signal. Once that’s been done, you’ll be ready to troubleshoot the problem with a known good X10 transmitter/receiver pair.  You can easily plug these devices in any available receptacle to test different branch circuits.

Or if you want to raise the bar and have the ability to direct-connect the controller or chime module at the hard-wired location of a suspected faulty device, cut a lamp cord leaving about 18 inches of cord attached to the plug end, remove power from the circuit, wire-nut the cord in place of the device, re-apply power and then plug in the controller or chime module.  Just be sure to use electrical common sense. Be safe.  This blog assumes no responsibility if you let the sparks fly like a 4th of July firework.

Do note that you’re not limited to using the chime module. You can easily subtitute a lamp module instead, and have the ability to test the BRIGHT/DIM and OFF functions.  I chose the chime module primarily for its audible feature, instead of having to move about to do a visual check as required with a lamp module.
