The DataPro 1394AB series cable is a FireWire cable (IEEE-1394) with one six-pin plug and one four-pin plug.
This is the most standard host-to-device
configuration, as most computers and
video hardware processors used the 6-pin
connector and most camcorders and electronics
used the smaller 4-pin connector.
Originally known just as "FireWire", now these cables are
called "FireWire 400" to distinguish them from the newer, faster
interface. Modern machines are more likely to utilize
FireWire 800 on the host end, but that
interface is backwards-compatible with legacy (FW 400)
FireWire cables provide high-speed
data transmission for digital audio and
video applications, most commonly for
transferring data to and from camcorders and hard drives.
The bus allows up to 63 devices to be
daisy-chained through a common interface.
