Firewire Cable The 9-pin connector is a rectangle with square corners. It has 5 pin contacts on one side and 4 pin contacts on the other. FireWire cable 800 9-pin connectors are part of a recent improvement to the IEEE-1394 technology called FireWire 800 (or IEEE-1394b). SinLoon1394 Type B 800 9 Pin Male to 400 4 Pin Male Cable The improvement to the specification allows transfer of data at up to twice the speed of the original IEEE-1394 standard. This connector type can be adapted to the older 4-pin and 9-pin connector. However when adapted the maximum transfer rate will be 400 Mbps.
FireWire 9-Pin to 4-Pin Cable is perfect for connecting digital devices such as scanners printers memory card readers cameras DV camcorders and iPods Complies with the latest IEEE 1394b standards for reducing radio frequency and electromagnetic interference.
