Ribbon cable tester? Does such a thing exist?

    Hi,
    I have a 50 pin ribbon cable that is carrying a large number of
    signals from various hardware components in a medical device I am
    trying to test. I'm looking for a device/connector that would allow
    me to gain direct access to any one of the wires/pins in the cable, so
    I could set the voltage on any pin. Furthermore, this ideal device/
    connector would allow me to disconnect any of the wires in the cable
    whenever I wanted. Does anyone know if such a device exists and who
    makes it?


    Thanks,

    Jason Mazzotta

    You need a 'breakout box'. Try googling.

    I'm not into "breakout boxes" - never had a need for one or shopped for one
    to know of any differences in size, style, hook up, etc.... I "did" end up
    with one from a Computer repair business buy out - which is in a small hard
    shell case - has some jumpers with it, etc. Uses either AAs or a 9 vdc
    battery I believe. Been looking to sell it off - for a reasonable offer -
    plus shipping.

    3M makes something that will accomplish this: One was just a male to female
    connector, about an inch long, available in the common pin counts (26, 40, 50,
    etc.) with dual-row 0.1"-spaced pins. Each circuit had a little slide switch
    which connected or disconnected the signal. The other thing they made was a
    very short (~1/4") male to female connector with another male header sticking
    out of the side, 90 degrees to the main body. This allowed you to either hook
    up a scrobe probe or multimeter to measure voltages, or connect voltages

    Ah, here they are: http://dkc3.digikey.com/PDF/T072/P0442.pdf -- 3M
    "Intra-Connector" and "Intra-Switch."
