  1. I am looking for a manual that came with early versions of this device.

    Seems as if the DIP switches assigments differ from the actual version,
    even the manufacturer hasn't any hardcopy or file.


    Thanks - Udo
     

  2. There are only so many permutations for that dip, you could try them
    all. Isn't it merely an I/O port selector?

    True., they're not that many configurations., I'd ask Hewlett Packard
    they are the GPIB pros in my book, though if is a really old model they
    may refer you to "Classic Computers" in Fairfield, IA. Tel. (515)
    472-0383 [# dates back to 1993] - you just need to define your
    application & hardware...I've got an old HP touch screen PC - I got the
    books from them - they describe in detail the hardware/application Vs
    dip addresses., but I'm not sure it's all 488 based to give you any more
    data. Good Luck !

  4. There is only a serial port connection between the device and the PC.

    There are 3 dips with 8 switches each. The only thing i found out by
    measuring the clock source for the UART is that the baudrate selector
    has a coding different from the manual. So i was able to establish the
    serial communication with the PC. The other thing i found out by a
    status query is the selector between controller&peripheral mode and the
    address if the unit itself, but it wasn't possible to communicate with
    any external device. So there must be a secret setting that i didn't
    find out or may be the device itself is defective...


    Thanks for answering.

  5. The device is not a plugin card for the PC...

    Thanks - Udo
