  • AS90 commline failure

    I've got an AS90 scorer that has a comline failure. Have had several mechanics swapping out boards with no results. Causes?

    Re: AS90 commline failure

    5 volt PS (check at the CPU board, not PS)
    dirty card edge connectors (AC and IO boards)
    IO board
    CPU board
    software on CPU board
    If a converted console, check all connectors between the AS-90 board and the cables to it.
    MAke sure even lane set on AS-90 bd, odd on IO.
    Make sure dip sw on IO not set to local.
    Loosen console and drop it from 36", retry.

      Tom:

      Same console with the breakers blowing??

      Solve the breaker issue first, probably kill the commline error with it:

        Change your A/C Panel out with lane next to it, if problem moves you have found your culprit.
        Still here. just a watchin now.

          Turned out 5 VDC was out of adjustment this cured problem on 3&4 but still having problems with 1&2.
