[App_rpt-users] Trouble with my USB URI

Try downloading the uridiag program from:


Un-tar it and 'make' it, then run './uridiag' and use option 'c' and it will
tell you how to make a connector for running the diagnostics.

This is the program that DMK uses to for production testing of a URI.

Subject: [App_rpt-users] Trouble with my USB URI

I had a note up and running well with not any real issues,  however after about 4-6 months,  the system no longer detected carrier on the cor line.

Sometimes it would think its always on and sometimes it would think its off.

I checked the voltage at the line from the radio  and that was working as it should.

I even reprogrammed the radio to try it voltage high instead of low for carrier.   This did not make any difference.

I have tried several radios Radius M100 CM300.  All work fine on the IRLP machine and all show proper voltage on the COS signal. 

I have the DMK URI with the eprom.   

Can anyone suggest any other diagnostics?  I would like to get the Node back up and running and/or order a replacement URI
