Sonnet's FireWire 400-to-800 adapter makes it easy to connect your FireWire 400 (1394a) peripherals to the latest Mac Pro, MacBook Pro, Mac mini, iMac, or any other computer with FireWire 800 (1394b) ports, without the trouble of purchasing yet another cable. Which cable to get? What length? Why bother-use your existing FireWire 400 cables with this simple adapter from Sonnet to connect devices to a FireWire 800 port. 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 cable plugs into your FireWire device). It can't get any simpler. Sonnet's FireWire 400-to-800 adapter features a 9-pin male connector that plugs into your computer's FireWire 800 port. The other end of the adapter features a 6-pin female FireWire connector that any standard 6-pin male FireWire 400 cable can plug into. Fully IEEE 1394 compliant, this adapter allows you to avoid the hassles of new cables and computer upgrades.
