FYI...There has been development on making UPB more noise tolerant. Testing continues before global acceptance by all manufacturers... We don't want to trade one problem for another. PCS, the inventor of UPB, has been working very hard to make UPB more tolerant of certain types of noise. I...

"After construction we noticed the signal was diminished" Could be. More wire = more impedance = lower signal levels. Did you add another breaker panel? The characteristic (transmission) impedance is affected by sub-panels. Using the Network Comm Test in UPStart can show you signal levels...

We have some tools that will help you in your struggle to learn and write UPB strings. It is not very intuitive but once you get the hang of it you will zip right along. There are two ways to get the tools... fill out a form on our website or send me an email. If you are using HyperTerminal...

Greetings! The UCT-08 was an early SAI product that was rendered obsolete after the release of the US2-40 and the ZTP (pedestal housing). The UCT was not the most reliable product and had the problem that most UPB products with LEDs on the buttons exhibit. The LED status will follow a Link...

UPB transmits at 4-40 kHz. A whole house filter would be large... think something like an isolation transformer large enough to handle the current in your house. It would keep UPB in the house and noise out. If you are certain the noise is coming from outside the house... I have a similar...

The password is only used for programming as Wayne suggested. You wll not have cross talk between adjacent Network IDs. UPB is a digital signal. Unless something is getting corrupted there should be no problem. Here in the office we use adjacent Network IDs and only have issues when someone...

It could be the power supply for the laptop. Electronic power supplies may create noise that is seen by UPStart. Noise that is in the 4-40 kHz range, and is in the position on the sine wave that UPB uses, show up in USPtart. A plug in filter might help. Many have had success with the Leviton...

Noise can be a problem when it is in the 4-40 kHz range that UPB uses. Often UPB will work when noise is present ... but sometimes it will not. One problem is that the UPB devices are very polite. The politeness is a collision avoidance scheme that may need better implementation. If a device...

Snow on the power lines creating noise? It is possible. Snow packing on an insulater may create paths for arcing. A tree branch whipped in the wind could havea similar effect. Odd that it would be at the UPB frequency... sounds like Murphy at work.

Can you send an ASCII string? The blink command would look like: 8904196A06251EFFA8 8904 is the control word 19 is the Network ID 6A is the Link ID 06 is the Source ID 25 is the Blink Command 1E is the rate FF is nothing A8 is the checksum...

Not currently.

Version 4.5, Build 2 wil be out shortly.

A key to phase coupler requirement is the distance from the power transformer. When a UPB signal goes from phase A to phase B it will cross the power transformer. If you have a 2000 sq ft house that is 500 ft from the power transformer it is likely that a phase coupler will improve the signal...

It is likely that you need a phase coupler, if you do not have one already. What are your signal levels on the phase you can see? Noise is a touchy subject in UPB land. UPB was originally purported to be noise immune... and it is very robust... it just depends on where the noise is and the...

My 2¢... It could be the master, the US2-40. Since you have already replaced the USR it is either the US2 or your wiring. If you have a voltage meter there are a couple of quick measurements to take. Dangle the US2 out of the wall... put a piece of paper on the wall to protect the paint...
