Fire Wire & daisy chaining

    what is the practical limitation to Firewire?
    Products like MOTU 896HD advertise that you can daisy chain
    more then one of their interface without using multiple firewire ports
    Is this true and to what extext can they be chained?

    just like ADAT cannot transfer more then 8channels 24bit/48khz
    what is the limit of Firewire 400? 800?

    The IEEE-1394 standard for FireWire sets a limit of 63 FireWire devices per computer. When connecting directly to your computer, there should be no more than 16 cable lengths between the computer's FireWire port and the last FireWire device.

    Not sure what kind of latency you would get though. :D

    I was curious about the answer to Redbort's question too. I think what Redbort is actually asking is about how many i/o's (tracks) can you run with multiple firewire devices. For instance if you had 3 MOTU 896HD's could you really expect to run 24 channels of i/o from your computers firewire bus? How about at high sample rates like 96kHz for 192kHz? I'm assuming a lot would depend on your processor and hard drive bandwidth capabilities.

    I guess if someone has a formula for how much bandwidth can go through a firewire port and how much bandwidth a track of audio at 24bit/192kHz (or 24bit/96kHz) takes up would answer the question for me.
    Thanks!
