    Can I substitute a ALL parallel cable for a TDIF-1 cable?

    Will it work?

    Thank you

    No. A TDIF cable is designed to swap its signals from one end to the
    other. It's a crossover configuration. A standard serial cable won't
    work. (I assume that you mean a serial cable rather than a parallel
    cable. The Centronics connector on a standard parallel cable looks
    nothing like the DB25 that's used on a TDIF cable.)

    It's pretty easy to build your own TDIF if you use a ribbon cable. Just
    make sure that when you crimp the DB25 ends on, they are reversed - pin
    1 on one end should connect to pin 13 at the other end.

    You should also keep in mind that the screw sockets on a TDIF connection
    use a different thread gauge than a standard DB25.

    I think it's metric rather than Imperial.

    No, but it's not hard to swap the leads around to turn a straightthrough
    cable into a TDIF cable. Somebody's DTRS web site out there had a full
    pinout for the TDIF cable.

    Not this again. It's dependent on the manufacturer that puts the TDIF
    port on his equipment. It's not any universal standard. For example,
    on Mackie's I/O cards (which fit their hard disk recorders and digital
    console), the analog I/O, AES/EBU, and combo Lightpipe/TDIF card all
    use 25-pin D-Subminiature connectors, and they all take metric locking
    screws.

    Well, it's Tascam's standard (TDIF, I mean, not DSub 25) & they use metric
    threads on their machines, although a Tascam TDIF cable comes with both metric
    & Imperial fasteners.

    You need to fire that employee.

    I have done this. But that was back in the days when the only TDIF
    cable available was the Tascam one which cost about $100. The one I
    made from a parallel cable worked but it was very flawed. Wrong screws
    and I hadn't respected all kinds of things like the twisted pair
    format. And who knows about nominal impedances.

    Now that you can buy from Cable-Up (which is Tascam anyway) TDIF cables
    at a very low price, there is no point to modifying a parallel cables.
    You will save yourself 10 bucks.

    Why don't you smoke 2 packs fewer this week?

    Have you tried docking your pay for the lost productivity?

    Yes, but everytime I count the money, my pile still equals his :)

    Put a drop of automatic transmission fluid on the thing, and hold the stud
    with pliers when you remove the screw.

    Then retap ALL the damn things for 4-40 so you never have to do it again.
