CMPLE 9-pin/4-pin BILINGUAL FireWire 800/FireWire 400 Cable – 15FT Clear This FireWire 9-Pin to 4-Pin Cable from Cmple provides a link between newer devices that feature the 9-pin FireWire 800 connection and older 4-pin FireWire devices. The IEEE 1394b serial interface, better known as FireWire® 800, doubles the speed of the older FireWire 400. It uses a newer 9-pin "beta" connector, which is incompatible with either of the older connectors.
