    Opencockpits Master card sharing the ground ...?

    Hi, as we all know master card inputs are in groups of 9 inputs and each has their own GROUND.
    What I would like to know can I share this ground EXAMPLE... Connect ground from all four groups then run this only one ground cable amongst all the inputs... It does seem to me it shouldn't matter and all should work just fine, but wanted to see if anyone might have done it and if it should work. Don't want to wreck the master card, but again I don't see there should be any problem in doing so.
    Thanks for any info

    Not a good idea. I have had very confusing results when I mistakenly mixed up inputs and used a ground from another set

    Andy,

    David is correct!! Never mix the “Group Ground” signals.
    They are actually a GROUP SELECT signal but are confusingly called Ground.
    If you merge those you'll not be able to distinguish between the inputs.
    E.g. if you merge all Group signals and have a switch at Input 1 (pin1),
    you will see that Input 1, 10, 19, 28, 37, 46, 55 & 64 will all be active
    Regards,
