    Basic MasterCard Question

    Sorry to bother you all, I just have a very basic question.
    I am confused as to whether the MasterCard possesses any Inputs or is it simply a central bus that when the correct module is connected, can allow for inputs?

    I can't seem to find any solid answer, the main this that confused me is the Rotary Encoder product page states 'Can be connected directly to master card'

    Sorry again!

    Re: Basic MasterCard Question

    Hi

    The Mastercard has 72 inputs available via a 40 way connector. The easiest way is to purchase from OC a breakout board which connects via a 40 pin flat cable to one of the mastercard sockets. The breakout board has provision for 36 inputs via screw connectors.

    The OC manual can be found here

    A word of caution as the number of usable outputs is only circa 38 (not 64 as their documentation suggests ), some outputs are used to multiplex the displays bus

    Regards

    David

    Right, but if you do not use the multiplexed displays on the card then all of the inputs can be used.

    Re: Basic MasterCard Question

    There are circa 38 outputs that can be user configured. The remaining ones are dedicated to the multiplexed bus for the 7 seg segment displays and DB9 connector etc and to the best of my knowledge are not accessible to the user. Do you know otherwise? If so then I would be interested to know how you access them through SIOC

    Regards

    Re: Basic MasterCard Question

    I have only hooked the card up to the PC to make sure all the settings were right (LPT) so far.... but I am worried about the usefullness of the card in my pit in terms of troubles getting it to work properly for my needs compared to the troubles getting there...

    Re: Basic MasterCard Question

    Hi David,
    I thought all 45 outputs were available??? 38 from the J2 40 pin connector numbers 11 to 48 and then another 7 on the P2 DB9 connector numbers 49 to 55?
    Have I misunderstood it again

    Cheers
    Mike

    Oops, you are correct. Apologies, I was focussing on the suggestion that the multiplex outputs were available for general use. Glad you are around to keep me in line
