Testing 1 2 3 Anyone here for an x10 question?

As traffic on this NG has been slow, to say the least, I thought I'd ask  
a question about some x10 problems. I have an XPCR amplifier/repeater  
installed in my house near the breaker panel, with its own breaker. I  
use an 1132CU to control all my stuff. I think the XPCR is repeating the  
signals and colliding with other signals coming from the 1132, i.e. the  
1132 sends several x10 commands sequentially, however they seem to  
collide with the repeated stuff from the XPCR. I've tried to put 1  
second delays in the 1132 to compensate, however, I still seem to get  
collisions. Example ... today the 1132 sent a "c14 on" to ring the chime  
module. The 1132 in monitor mode saw the command, however, the chime  
never sounded. Early this morning, it worked perfectly. Any ideas?

I have pretty much the same config running for years: 1132CU controller  
with an XPCR at the breaker panel.  In addition, my 1132CU is plugged  
into Jeff Volp's XTB booster.  Well over a dozen x10 lamp & appliance  
modules littered throughout the house.  I don't have any delays in the  
1132.  Never had any problem with collisions with this setup.

Almost all my reliability issues have been traced to signal strength,  
not collisions.  Luckily I have access to an x10 signal meter.

Long ago, I did have a problem that was traced to a flaky TM751 RF  
module.  It seemed to be occasionally belching out x10 signals to the  
powerline.  Replacing that module cured the problem.

Junk your XPCR and get a Jeff Volp XTB-IIR repeater. I know it will cost  
you, but I did it and my problems went away. Regards...Jerry Albin

I've always wanted to get an XTB-IIR, however, it's always looked a bit  
rich for me, even thought I've heard very good things about it. I had an  
XPCR in my old house, which was a more urban location. The unit worked  
poor at best. It sent all kinds of random X10 signals, apparently  
triggered by line noise. I tried 2 units and finally gave up. Here, in a  
very rural environment, it works well for the most part.  But, I have  
seen some really weird, unexplainable problems. My question is, did you  
get the kit or the fully assembled unit? Also, in the XTB-IIB  
literature, it mentions that it might not play well with the 1132 due to  
amplifying line noise.
Link: http://jvde.us/xtb/XTB-IIR_description.htm ... here's the quote:
"Both the XTB-II, and the XTB-IIR include a bandpass amplifier for X10  
return signals. The XTB-II used the cost-effective workhorse LM318 for  
that amplifier, but the XTB-IIR uses a significantly more expensive  
Analog Devices AD817 to obtain the best possible performance. In  
addition, the XTB-IIR includes a gain switch to allow it to receive very  
weak signals in a relatively noise-free environment, while providing the  
ability to recover stronger X10 levels in the presence of high  
background noise. The bandpass filter will attenuate out-of-band noise,  
but line transients can still make it through, and are amplified.  
Devices sensitive to noise, such as the PowerLinc 1132, may not work  
well with any of the XTB units."

Is this not a problem?
Thanks again ... maybe we can get this group going again ... there was  
always a lot of good info when it was active.

My setup has the 1132 plugged directly "atop" the (original version)  
XTB.  Although I have a number of macros in the 1132, they're all  
triggered by the 1132 itself.  None of them are ever triggered by other  
x10 controllers in the house.  My 1132 also doesn't depend on the status  
returned from any x10 devices.  As a result, my 1132 doesn't much care  
about returned/amplified noise by the XTB (which might get incorrectly  
interpreted as x10 codes).

I got the assembled unit. That way you know it WILL work. I only do simple  
PCBs.
 I have a 1132cu connected to my old XP Dell for Smart Home software. I don
't seem to have any problems with the XTB-IIR. You should really direct XTB
-IIR questions to Jeff Volp. I'm not qualified to answer your question. Jef
f is a great guy and will help you out. BTW, don't forget to use X10 filter
s on ALL wall warts, TV's, computers, printers, etc. or get 2 of Jeff Volps
 filter units.  Ask me how I know...GRIN..  Regards...Jerry Albin
