Hi,
Just thought I'd report back on this in case anyone else is having trouble, as I managed to fix it last night.
Compatibility mode didn't make it work, but thanks for the suggestion!
Everything I have for the meter is the most up to date versions - drivers, software etc, and yes the meter was switched on!! :wink:
After 2 hours of hunting around on the internet it seems that the version of Vista you are running can cause the problem.
It was simply a case of downloading a 3rd-party driver for the cable and bingo! Now all running smoothly!
So, if anyone else is having problems search for a "serial to usb adaptor driver" on google, install it, and also make sure that the DMS software is looking for the cable in the right place! (For some reason mine didn't work with autosearch on, I had tp manually tell it which COM port to look at)
Hope this helps anyone else!
