I just installed my new XTB-IIR yesterday (firmware v1.22) at default settings. As advised by Jeff, I did not plug my 1132U PLC directly into the booster port (its a 3 prong device, anyway), but left it connected in its original spot - next to the panel (similar distance - about 1 foot) as the XTB-IIR is from my panel. While waiting for delivery (which was FAST), I had prepared by installing a dedicated breaker for the XTB-IIR, and a dedicated junction box to connect the new coupler/repeater. I also plugged my V572A into the XTB-IIR's TW523 port. It took 10 minutes because of that preparation - and I was going slow/carefully!
Results:
1) Every device plays perfectly together! And I have about 20 X10 switches/modules accumulated over the years.
2) Signal level due to the XTB-IIR is absolutely shocking - pun intended! (**more on signal later**)
3) I already had a fairly "X10 compatible" house. Many years ago, I had installed two large 15A filters with powerbars in the two most concentrated A/V zones in the house, and three 5A filters on the three computer/laptop areas, as well as a dryer-type phase coupler. I've been using the technology since about 2002 or so - but had let-it-ride for many years and had begun to see reliability/degradation in some outlets. When My PSC05 (used with V572A) failed over the Xmas break, I did some online research and discovered Jeff's many XTB solutions - the write-ups sold me.
**Signal Level**
I cannot find an outlet in my entire (2500 sq ft - built in the early '90's) house without incredible X10 signal! Since I had started X10 many years ago, I had an old/original TesterLinc/1132B (Smarthome) for signal testing. After the install, I took it around my house looking to see what Jeff's "Phaser-set-to-Kill" had accomplished. I was in for a huge surprise.
The highest signal quality (some obscure number system devised by the TesterLinc folks) that I had ever seen in my home on TesterLinc was 88, but most often it was in the low to mid 70's. BUT here's where it gets interesting. The TesterLinc was never designed to take the shot-in-the-head that Jeff's box delivers! It was designed with "100" as the absolute peak level that X10 could "possibly" be measured.....or so they thought. To the old TesterLinc's credit, it still managed to designate a TesterLinc quality number (except now, from a low of 128 to a high of 139!), but it no longer could decode the X10 address - instead every code started with BSC (bad start code).
But that wasn't true! Every X10 address throughout my home was perfect (but apparently "too loud" for the old TesterLinc). To be sure, I augmented my outlet testing with and old Smarthome SHL2000 and a night light (a device I had found to be useless in my home, for lack of reliability) - and it worked perfectly everywhere. Amazing!
Performance throughout the house is 100%, I'm sure. The tests were performed while my wife was at work; so I could crawl around and check even the most hidden of the outlets and behind some switches without the inevitable eye-rolling that would occur if she were present. I only gave up on testing three outlets because I'd be moving a queen size bed, a china cabinet, and a bookcase by myself. I think I'll take it on faith that those are 100% also!
The rest of yesterday (wife away) was spent removing and old Boosterlinc; the passive coupler; exension cords behind couches (which were there due to the nearby outlets being unreliable); loading fresh batteries in 10 motion sensors which are now working at the speed of light; and installing a sensor and WS13A in the pantry so open door=light (that light switch location was dead to the old system).
I also spent time on my Smarthome Manager program/upload before nightfall; editing out dimming delays (eg. pauses) that were there to ensure dimming completion to desired levels (which was an issue).....they are simply not needed any more!
My compliments Jeff - you have built a box that exceeded my expectations 10 fold. Since X10 has become a little bit abandoned due to the noise caused by modern devices impacting legacy systems; I'll have a cheap source (eBay) for any additions I choose to make. Personally I'm sticking with X10! Its a win-win.
