Hi.

I have a Macbook with 1 firewire 400 connection. I have a Protools Mbox 2 Pro (firewire), and a 1Tb external firewire 400/800 hard drive.
My question is:
I only have one firewire connection on my computer, yet I need to connect my firewire Mbox2 Pro AND External firewire hd in order to operate & store the data. Do I connect the Mbox Pro to the external hd, and the hd to the computer, or, the Mbox Pro to the computer, and the Hd to the Mbox?

Hi muhsdoc,

The FireWire (IEEE1394) is a serial bus interface, that means that you can connect up to 63 devices in a tree topology (hierarchical network).

Theory left aside, it doesn't matter in what order you connect the devices - they will still function. The only difference is the self-id assignment (depth-first, post-order), but it doesn't affect the performance of the connected devices (that is done using a quality protocol defined at interface-level).

In an ideal world, you can install them anyhow. Still, I suppose that transmission quality for the external audio interface has priority, and reasoning that shortest-length + fewer connectors => smaller transfer impedance => better signal quality, I'd suggest the following setup: Firewire from Mac to Mbox, then from Mbox to external HDD.

Cheers.
