[arm-allstar] Question about timing/responsiveness

Sat Mar 5 14:02:27 EST 2016

I think the key here is that you say the repeater is on a "hardware base controller" By that you mean that Allstar is not controlling the repeater? How is Allsar connected? Through a port on a hardware controller?
Is The Allstar computer actually at the site or elsewhere? I am assuming elsewhere since you say there is no internet there and you talked about network dropouts.

It would help if you gave a list of components and how they are connected and where in relationship to each other they are located.

    I'll try to shed more light.

    The original setup was using a desktop configured with Zipar. Same
    link radio for both configurations, so nothing there is different.
    It worked fine with that setup. The only change was going to a
    Raspberry Pi2.

    The repeater is on a hardware-based controller (no Internet
    available). When a user brings it up, the repeater transmits PL the
    entire time the user is there. When the user unkeys, the PL stops
    encoding, but the repeater's hang timer keeps it transmitting for
    the predetermined length. During the hang time there is the courtesy
    tone and possibly ID (without tone).

    Using the Raspberry Pi, I can sometimes hear a brief burst of the
    beginning of the repeater's courtesy tone. With the desktop
    configuration that did not happen. Again, using the Raspberry Pi it
    also sometimes "hangs" the AllStar side for a second or two. So
    there's two things happening with this part of the issue.

    Hope this helps.

           To start with the drop outs. This is more than likely an
          Internet problem and that would be the first place to start
          looking. Not knowing anything more about his system like what
          the Internet connection is, etc. It would be hard to suggest
          anything.

          The other problem may or may not be related to a poor
          connection. When the PL input to the repeater  drops it should
          immediately drop the COS signal. The first place to check
          would be to make sure this is happening. If there is some kind
          of delay in the repeater and COS is staying true then it would
          have nothing to do with Allstar. When I say "true" that could
          be a high or low depending on the configuration. Put a meter
          on COS and key into the repeater and see how it follows.

          Again not knowing his configuration it is hard to know what is
          actually happening. Is another controller in the loop? The
          best and simplest way to use Allstar as a repeater controller
          is to do it exclusively. The input PL drives COS  and the PTT
          output drives TX PTT and TX PL. All the timing, ID's etc. are
          done in Allstar.
