2.3.1. FireWire
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.
Pushing the speed barrier to new limits, FireWire 800 offers increased bandwidth and extended cabling distance between
devices. FireWire 800 is ideal for bandwidth-intensive applications, such as audio, video and graphics. Benefits of FireWire
800 include:
• Resourceful architecture: FireWire 800 reduces delays in arbitration and signal distortion, and increases throughput.
• Backwards compatibility: adapter cables allow FireWire 400 devices to operate under the FireWire 800 port.
FireWire 400 and FireWire 800 also share the following features:
• Hot-pluggable: devices can be added and removed 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.

FireWire Icons
Theses icons will help you easily identify the FireWire interface. They appear on FireWire cables, and next to the FireWire
port connectors on certain computers.
FireWire Cables
There are two categories of FireWire cables on the market: FireWire 800 cables, which feature the 9-to-9-pin, 9-to-6-pin,
and 9-to-4-pin cables; and the original FireWire cables which feature the 6-to-6-pin and 6-to-4-pin cables.
