KIO2

[Gilbert J Cross]

        Hi fellows. Can't manage to communicate between computer and K2.
Through control program or HyperTerminal verified that serial port is
functional on the computer ( Win XP ).
        Can hear Q1s signal loud.
        Here are some voltage measurements made this morning.
        U1-1 14.12 shud be 14
        U1-2 -1.3mv    "        .1
        U1-3 13.65     "        14
        U1-4 -5.4mv    "       .1
        U1-5 -.017mv   "      -8
        U1-6 -2.38        "      .1
        U1-7  13.66      "      14
        U1-8 -3.13        "      -9
        U1-9  0            "       0
        U1-10   0          "      0
        U1-11  4.89      "       5
        U1-12   4.98      "      5
        U1-13  4.89      "       4.5
        U1-14   0          "       0
        U1-15   4.89      "      4.5
        U1-16   4.89      "      5
        Wonder if getting voltage on pin 8 would to proper level would
cure the problem?
        J1-1   0        shud be    0
            2   -.011       "         -8
            3   -2.36       "         .1
            4    6.27        "        4.5
            5    0             "         0
            6    5.62        "         5.5
            7    0             "         0
            8    14.12       "        14
            9    8.18         "        8
        Voltages on J2 are in limits.
        Any help would be greatly appreciated.
                        Thanks   Gil   K8EAG
