I have a JCI UNT 140-1 that isnt communicating. Not sure if its working or not cause I didnt want to dig that far into it today.... but it wont communicate with the workstation and when I connect directly to it I cant get any controller information...cant upload the configuration to my laptop...wont commission....etc....
Disconnected the inputs...changed the address...cycled power to it several times..... nothing...
Its bad.... but one thing that puzzles me is that the green led on the UNT is flashing at a very high rate and its a steady rate.....and the UNT is also making a high pitched whine.... almost like a relay buzzing at a very high frequency.
Just wondering if anyone else has run into this before and what may have caused it.
