    Thanks for the quick reply. But what I required was what voltage goes
    into which pins, that is +5v, -5v, +12v, Gnd., etc. This is because I
    would like to try to run it on Computer Power supply. If some body has
    a power supply, the pinout diagram is printed on the power supply unit.

    Well, even though it's five years on, I'm going to post this here in case anyone has the same question,
    just for the sake of usefulness.

    Looking at the back of the PIX-506:


    1: 0V (Black)
    2: Power On (Green)
    3: 0V (Black)
    4: -12V (Blue)
    5: +12V (Yellow)
    6: +5V (Red)

    The colors correspond to those found on a standard ATX power supply.
    (Check with a known ATX pinout first as some manufacturers stray from the standard)

    One convenient feature of the ATX connector, is that on the end with the 3.3 Volt pins,
    the connector is keyed in the same way as the PIX one, so if you don't
    mind permanently modifying the PSU, it can be cut down and re-wired
    so it'll plug into the PIX without having to open up the PIX or otherwise
    modify it.

    As usual disclaimers apply, if you blow yourself or your PIX up in doing this,
    it's neither the fault of the author or this forum :)
