CM15A Unacceptable RF Range

<< < (2/5) > >>

sys4me:
In response to Tuicemen... Jeffvolps interference tutorial seems to refer mostly to powerline functions. My problem is strictly RF reception. With the transmitter more than 15 feet away, install does not work, waits for signal forever. As soon as antenna enhanced or distance reduced below 15 feet I get configuration complete message on install. You guys will have to work a lot harder to convince me there is anything other that a poor RF receiver causing these problems. (the fact that my second receiver is 3 times as good as the first one should be a clue).(the fact that the DX7000 works perfectly on RF in the same house should be a clue). Please note that I have worked in Radio and electronics and computers for 43 years. This unit is poorly designed or uses poor quality components or the RF is not tuned properly at manufacture.

Tuicemen:
The CM15A wasn't originally designed to work with the security modules signals they send are different how ever still RF.
I did have issues setting up my security modules with AHP (had to install in close proximity) but after the install was complete they worked from the spots I placed them! ::) ???
The fact that the CM15A  is capable of receiving many different RF commands may be the problem  ::) ???
We're not saying that your particular units are not defective, just that all possible situations need to be looked at!
Have you looked at the activity monitor?
Is there any unexplained RF activity?(note: it only shows recognized comands not unrecognized command sets)
 :(

Phoned support, they assured me that CM15A's normally had good RF receiver performance and sent me a replacement

I am amazed at the number of people who don't have range problems with the AHP interface. I know in my case... the metal lathe in my walls makes RF a problem.

I also performed a mod on my interface.... a really simple easy... break off the antenna tip - solder on a wire - tape the wire to the old plastic antenna tube. There is (as you know) an entire thread dedicated to extending the range of the AHP.

I am crazy about the added features (particularly BVC) I now have with AHP..... I hope you find your rough start with AHP as rewarding as mine.

You know this is absolutely pathetic all the little modifications you have to do to this equipment I just keep thinking the big wigs are just laughing their *&^%$ off at all the stuff we have to go through to get some of this equipment to work. I saw one modification that looked like it came from the X Files!!!, really bazaar the extremes we have to go through, just never quite seen a company like this take the dx7000 console it's been around more then 12 years without any major improvements had a friend that was on vacation his house was broken into the equipment did it's job the crooks didn't get anything but his lights all stayed on full bright for almost three weeks cuz his sister misplaced the keys he gave her, and there was no way for him to call into the thing to cut them off. I just don't think these people care that's probably why they lost their contract at Radio Shack poor quality and the fact they refused to address the issue that it's possible for you can get around the 49-1000 console with something as simple as a Palm pad. The CM15a has INCREDIABLE potential but with lousy software, I love the way it looks but it's not reliable and is buggy as all getup, here it's almost 5 years out and people are still experiencing problems with timers and the latest update is actually worst then the last! I got a macro that instead of sending one dim command sends multiple dim commands so that my front porch lights are dimmed to complete darkness, well there you have it my 4 cents just hope that someone is listening at x10 before it's to late, even some of their die hard customers like me are just about no I take that back, just feed up!!!!

I agree Tom j!! We should NOT have to wait so long.... and work so hard for home automation. If there was a better, more advanced, more reliable, higher tech home automation device than the CM15A, even at three times the price..... I would own it!

Do you have a link?

I guess that i am one of the lucky ones, butI have bought some of my success with x10. The CM15A is what it is. The quick little antenna mod was easy and it did extend the range somewhat. I have x10 installed in two homes and the systems work rather well within x10's own capabilities. Therefore, considering the limitations of x10,  I have added a  RR501's polite tranciever to each home and a repeating phase coupler. That really seems to solve most of the sendplc or sendrf problems. That's it.
