  • Xenarc 700IDT problem with Intel MacMini?

    Hi all,
    I seem to have encountered a strange problem with a
    Xenarc 700IDT 7" VGA In-Dash Monitor and a Mac Mini Intel.
    After about 5 minutes, the touchscreen stops working
    If I reboot I get another 5 mins of working touchscreen

    Anyone encounter this?

    I have a idea what is wrong.

    I have two mac mini's -- a Power PC mac mini and a Intel Mac mini
    When I use the PPC mini I do NOT have the problem, but when I use the
    Intel unit I do, The differences in the USB is the PPC is 1.0 USB and the Intel
    is 2.0 - USB cables have a max length of 15' I am using:
    http://store.mp3car.com/ProductDetai...Code=CBL%2D023
    Which is 16.4 feet.

    I am wondering if maybe the problem is that I am JUST at the threshold and
    that the increased speed of USB 2 is causing the problem.

    I am going to slice open the cable and shorten the length of the USB
    I have the shorter cable which I am disecting.

    Here is what my investigation has shown so far

    Ground
    Black
    White
    Red (5v) is not used

    Blue is VID 2 ground
    gray is VID 2 Positive

    Green is VID 1 Ground
    Purple is VID 1 Positive

    There is a 2 wire black wire (thicker then the rest) That is Audio In
    (an unused cable on the 700IDT)

    Xenarc uses 3 wires for there USB

    Anyone ever color code (or have a wiring diagram for the whole cable)
    they can upload or email me?

    I want to go in there fully armed before I slice into my harness

        Here's a pretty howdy do...

        Nope didnt work. rewiring the USB to a local hub, didnt work.
        Oh and the Cable Chart they give is wrong -- Black/white is Black on the
        cable...

        Now I gotta come up with another solution
        (and I think its gonna be a MAJOR job..)
