FireWire 400, also known as IEEE 1394, is a high-
speed serial input/output technology for connecting
peripheral devices to a computer or to each other, and
FireWire 800 is the implementation of the new IEEE
1394b standard.
FireWire 800 offers increased bandwidth and ex-
tended distance between devices. FireWire 800 is ideal
for bandwidth-intensive applications, such as audio, video
and graphics. Please see chapter

❖
Backwards compatibility: adapter cables al-
low FireWire 400 devices to operate under the
FireWire 800 port (at FireWire 400 speed).
❖
FireWire 400 & FireWire 800 Benefits
Hot-pluggable: devices can be added and re-
moved while the bus is active.
❖
Isochronous data delivery: no dropped frames
– FireWire supports real-time data delivery.
❖
Flexible: up to 63 devices can be connected on a
single bus.
