About 1394 Technology
1394 (also known as FireWire or i.LINK) is an international
standard data transfer protocol created by Apple Computer, Inc.
and ratified by the International Standards Organization as IEEE
1394. It is a series of standardized commands for moving data from
one device to another.
1394 offers advantages that make it ideal for use with audio and
video devices:
■
It’s fast. It has 100/200/400 Mbps, or 12.5/25/50 MBps data
transfer rates.
Note:
FireWire 800 or 1394b technology provides faster
transfer rates; however, your Adaptec AUA-1422
DuoConnect for Notebooks adapter supports FireWire 400
or 1394a speeds only.
■
It features both isochronous (guaranteed bandwidth, ensuring
full-frame, full motion video, and CD-quality audio) and
asynchronous data transfers.
■
It is hot-pluggable (meaning you can connect and disconnect
DV devices without rebooting your computer), and has no need
for terminators or device IDs.
■
It supports up to 63 devices with a 4.5-m flexible cable between
devices over a total length of up to 72 meters or 240 feet.
