Try downloading the uridiag program from: http://svn.ohnosec.org/viewvc/projects/allstar/uridiag/trunk/?root=svn&view=... 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.

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 Craig VA3DTF _______________________________________________ App_rpt-users mailing list App_rpt-users@ohnosec.org http://ohnosec.org/cgi-bin/mailman/listinfo/app_rpt-users
