    Hyper Terminal is a Windows program. You will need a communications program that is made for your operating system.

    I found one called QuickTerm. I got it running, and it's giving me the same data as my program does. I'm going to dive into the settings a little and see if I can get it working that way.

    If you are getting the same values with QuickTerm as your program, are you sure the devices are actually outputting anything other than the high 3 bits? Do you have to initialize your hardware before they will transmit the data?

    The engineering team that built the nodes has demoed them with their program, and they work fine. Their program was written in C# on Windows. If that makes any difference...

    Without seeing the "Demo" program it makes no difference. Their demo program may initialize the hardware before they use it. Since your program and the terminal program see the same data, that would suggest to me that the problem is possibly hardware related. Do you know what type of connections are being used? Does the cable from your units have more than three wires? If so what is the pin out?

    Well... Seems as if the engineering team decided to leave out an important detail. The nodes won't transmit usage data if the wattage is below a certain level! I have been using a couple of dinky little clock radios. So I decided to try and plug something more substantial into them, (a couple of old G5 towers sucking 170 watts a piece) and presto chango, My Program Works!

    Thanks again to everyone for all of your help, and sorry to have bothered you all with a problem that wasn't really a problem,
