FIREWIRE FREQUENTLY ASKED QUESTIONS
How do I know which cable I need?
There are several types of cables available.
¾
6-pin to 6-pin cable
.
This cable supplies power to the FireWire bus and is most commonly used for
connecting to devices such as FireWire Hard Drives, FireWire CD-RWs and other common 1394
computer peripherals.
computer peripherals.
¾
6-pin to 4-pin cable.
This cable does NOT supply power to the FireWire bus and is usually used to
connect to DV Cameras or other self powered devices.
¾
4-pin to 4-pin cable.
Used to connect 4pin iLink devices (almost always video cameras) to other iLink
devices or to computers (Sony and a few other Windows computers) using the 4pin iLink ports.
¾
9-pin to 9-pin cable.
This IEEE 1394b 9-pin to 9-pin cable connects an 800Mbps computer to other
IEEE1394b compatible computers or devices. It has twisted pair construction and quad shielding to
ensure optimum data transfer speed without any data loss. Additionally, it also supports plug and play
and hot-swap features.

and hot-swap features.
¾
9-pin to 6-pin cable.
Used to connect a standard FireWire device or computer to an 800Mbps
connector. Example: connecting any legacy device (hard drives, DVD drives) to a new faster FireWire
800 port on your Mac.

¾
9-pin to 4-pin cable.
Used to connect an 800Mbps device or computer port to a 4-pin “iLink”
connector, like those used on video cameras and some Windows computers. Example: Connecting your
video recorder to a computer equipped with the new 800Mbps ports.

• Why are some FireWire cables 4-pin and others 6-pin?
The 6-pin cable carries data and draws power from the FireWire bus. The 4-pin cable is used to carry data only, it does not
draw power from the FireWire bus, most often seen in self-powered devices like digital video cameras.

• Why are some FireWire cables 9-pin?
This is the new bi-lingual connector designed by Apple for the FireWire 800 (1394b) standard.
800 devices have 9pin ports where 400 devices have 6-pin ports (and then there are iLink connectors with their own 4-pin
connections). So depending on your computer and your FireWire device, there are a few possibilities. Of course you can get
them all here, but with all these different connections and “beta” and “bilingual” cables, you might be still ask…

• What are beta and bilingual cables? Which connectors do I need?
“Beta cables” are the true FireWire 800 cables, intended for connecting a 1394b device with a 1394b port on your personal
computer. Both ends have a 9-pin connector, compliant with the 800 standard, designed to get all the speed of FireWire 800.
“Bilingual cables” are those that have a 9-pin connector on one end, for an 800Mpbs device or port, and an “A” connector,
either 6-pin or 4-pin, on the other. FireWire 800 is backwards compatible so if you have a FireWire 800 device but your
computer is still FireWire 400, you can still plug and play, although you’ll need one of these special cables and you’ll miss out
on some of the speed of FireWire 800.

• What is the maximum length a FireWire cable can be?
The maximum cable length for connecting device to device is 4.5-meters. A 10 meter cable may be used in conjunction with a
repeater when it is necessary to extend FireWire cables over long distances. You must however have a hub/repeater for every
10 meters of FireWire cable used. This is necessary because as the signal travels through the wire it begins to weaken. This is
known as signal degradation, a hub/repeater simply amplifies the signal, thus allowing it to travel further.
