Avoid Hassles—Just Adapt!
Sonnet Firewire 400 to 800 Adapter / Converter: Which cable should I get? What length? Why bother? Use your existing FireWire® 400 cables with this FireWire adapter from Sonnet to connect FireWire 400 devices to a FireWire 800 port, without going through the trouble of purchasing yet another cable.
Just plug it in between a FireWire 800 port and a standard FireWire 400 cable's 6-pin male connector (the other end of the FW400 cable plugs into your FireWire device). It can't get any simpler.
