[arm-allstar] Weird URI problem

[Doug Crompton]

Pat,

 I want to make sure I understand what you are saying. You say when it hangs the DMK URI red led is off and the PTT line is at +5V.  I am assuming that 0V or PTT grounded asserts PTT on that radio. So if that is the case the problem is obviously in the radio. Especially if you have to reset it to get the PTT back in order. I don't think there is anything wrong with the rest of the system.

As Dave pointed out though make sure the power supply is working properly before condemning the radio.
You can exercise PTT in the Asterisk client -

asterisk -rvvv

CLI> susb key  
CLI> susb unkey

The red light and the PTT line should follow.

          I'm not sure which board to post this on...
      My repeater is a
          Motorola
          R1225, 25Watts, w/ PL. The computer is a BeagleBoneBlackC. I'm
          only
          using the COS, PTT, Rx Audio, Mic and ground. This system has
          been
          working on the AllStar Network since May 2015.
      About 2 months ago a
          weird problem
          started: The Xm hangs on, but PTT voltage is at 5v. The URI
          red led
          is off. If I just wait the timeout timer kills the Xm but the
          the PTT
          doesn't work until I reset the 1225. The Rptr Rx led is off
          the
          whole time, so there's no incoming signal. This only happens
          when the
          URI is connected to the accessory plug. I put my spare
          R1225 on-line and the same thing happens.
      Note: I have
          everything
          working off of an Astron SS30 power supply. I looked for
          ground
          loops, but didn't find any.
      I borrowed an URI and
          the
          system worked perfectly. I returned the URI and put the
          repeater on-line/stand-alone for two weeks with no problems.
      I sent the URI back
          to DMK
          engineering and it passed their test, so it was returned to
          me. I put
          it on line and the same problem started again. I swapped the
          the two URIs
          and my machine worked perfectly but the other machine started
          to
          kerchunking by itself. I returned the borrowed URI, and put my
          machine on-line/stand-alone.
      I would like to know
          if
          anyone has had this problem and what was your solution.
      I called DMK
          engineering
          to see if they would warranty the URI, no decision yet, but I
          ordered
          a new URI to get this node working.
      Aloha,

          Pat
