Was the Firewire IEEE 1394 protocol changed since 1997

  1. I have an Adaptec 8920 Firewire card which works
    with the Sony VX-1000. Both of these date from around

    I recently bought an OrangeMicro Firewire card to use
    instead of the Adaptec because the OrangeMicro card
    supports a repeater. But it doesnt recognize the
    camcorder. Sony support does not include sharing their
    expertise with other manufacturers' products and
    would not tell me which Firewire card would work
    and which would not.

    OrangeMicro support was not much help either except
    for them claiming that the Firewire protocol has
    changed at some point which would explain why the
    Sony VX-1000 plus Adaptec 8920 Firewire card works
    but their product does not.

    I am writing to ask if there are more than one
    Firewire protocols. I would really appreciate if
    could point me to any info on the Web about this.

    Thanks in advance for your help.

  2. There is a new FireWire 800, but it is supposed to be backward compatible
    with the 400 speed.

    Yours sounds like a chipset issue - there are a few different chip
    companies making 1394 chips, and there are subtle differences between
    brands. I haven't kept current with what works where, but a few years back
    the TI chipset was considered the most compatible with Windows and
    different camera vendors. If you can see the brand on the most complex chip
    on each of your cards, I bet you'll find they are from different companies.
    Google for the chip manufacturer, your OS, and your camera combined...
