There are two kinds of FireWire connectors: a 4-pin connector (typically found on video
equipment such as camcorders or decks) and a 6-pin connector (used for computer
equipment). However, some newer video equipment uses the 6-pin connector, and some
video interfaces use the 4-pin connector. See your equipment’s documentation for more
information.
FireWire 400 (6-pin)
(Sometimes labeled iLINK)
FireWire 400 (4-pin)
FireWire 800
FireWire 800, also called IEEE 1394b, is the next generation of FireWire after IEEE 1394a,
a higher-bandwidth version capable of data transfer speeds of up to 800 Mbps.
FireWire 800 is also capable of supporting cable distances of up to 100 meters.
In addition to the standard 9-pin-to-9-pin FireWire 800 cables, 9-pin-to-4-pin and
9-pin-to-6-pin FireWire 400 to FireWire 800 cables are also available to connect older
devices to a FireWire 800 interface.
FireWire 800 (9-pin)
Note: FireWire 800 is commonly used to connect hard disks and other data peripherals
to your computer, but this connector is rarely used to connect video devices.
USB (Universal Serial Bus)
USB is a consumer standard used for computer peripherals and other devices. USB 1.1
offers a much lower data transfer rate than FireWire (11 Mbps). USB 2.0, however, transfers
data at 480 Mbps. It supports plug-and-play operation and the ability to connect several
devices in sequence (daisy-chaining). Some USB devices draw their power over the USB
cable, while others require a separate power connection. USB 2.0 ports are included on
all current Mac computers.
There are two kinds of USB connectors:
• A connector, typically used to connect a device to a USB hub
• B connector, typically used to connect devices together, and also to connect a device
to a computer
