Great for connecting MacBook(R) Pro to older video cameras with 4 or 6 pin DV Firewire! IEEE-1394b is the latest in FireWire technology, and our IEEE-1394b or FireWire 800 cable provides transfer speeds up to a blazing 800 Mbps! This is twice the speed of the original 1394 standard, and is a real must-have for transporting and networking multiple types of digital data between users and systems. Digital Video (DV) camcorders, scanners, printers, videoconferencing cameras, and fixed disk drives can all share a common bus connection not only to a PC, but to each other as well.With Windows(R) ME(R) or Apple's FireWire Target Disk Mode you can use an IEEE-1394b cable to connect two computers together to enable filesharing.Hot-pluggable, our FireWire supports plug-and-play operation. This cable is designed to be 100% compatible with Apple(R) FireWire(R), Sony(R) iLink(R), and all other IEEE-1394 peripherals; also compatible with PC, Mac(R), Sun(R) and other IEEE-1394 equipped computers. Twisted pair cabling and shielded construction ensure our IEEE-1394b cable meets or exceeds current IEEE-1394b standards. Molded strain relief protects ensures years of trouble-free data transmissions. When connecting to 1394a legacy devices, the data transfer speed is 400 Mbps due to 1394a limitations.Connector 1: 9-pin 1394b MaleConnector 2: 4-pin 1394a MalePlease Note: FireWire(R) and the FireWire symbol are trademarks of Apple(R) Computer, Inc., registered in the U.S. and other countries.
