Firewire Connector Pinout Hard, drive, install, specifications, FireWire was developed by Apple systems (Apple) 4-Pin FireWire 400 connector. This connector is not powered. FireWire can
connect together up to 63 peripherals in an acyclic network structure (hubs, as
opposed to SCSI's linear structure). It allows peer-to-peer device
communication, such as communication between a scanner and a printer, to take
place without using system memory or the CPU. FireWire also supports multiple
hosts per bus. USB requires a special chipset to perform the same function,
effectively resulting in the need for a unique 9-Pin FireWire 800 connector The full IEEE 1394b specification supports
optical connections up to 100 metres in length and data rates all the way to 3.2
Gbit/s. Standard category-5 unshielded twisted pair supports 100 metres at S100,
and the new p1394c technology goes all the way to S800. The original 1394 and
1394a standards used data/strobe (D/S) encoding (called legacy mode) on the
signal wires, while 1394b adds a data encoding scheme called 8B10B (also
referred to as beta mode). With this new technology, FireWire, which was
arguably already slightly faster, is now substantially faster Two types of connectors are used with FireWire; 4 pin connector (consumer electronics), and a 6 pin connector (computers). The 6 pin connector has the following pinout: Pins 3/4 are crossed with pins 5/6 at the opposite ends of the cable. The transmitter sends clock [Strobe] on 3/4, and data on 5/6. ![6 to 4 pin Firewire [IEEE-1394] connector Pin-out](Firewire.jpg.jpg) The pinout table for the 4-Pin and 6-Pin connector is not an interconnection table, it just defines the pinout. Use the schematic above to determine interconnection.

standard 1394 which is currently a composite of three documents: the original
IEEE Std. 1394-1995, the IEEE Std. 1394a-2000 amendment, and the IEEE Std.
1394b-2002 amendment. Sony's implementation of the system is known as i.Link,
and uses only the four signal pins, discarding the two pins that provide power
to the device in favour of a separate power connector on Sony's i.Link products.
and expensive cable, whereas FireWire requires only a cable with the correct
number of pins on either end - (normally 6). It is designed to support
plug-and-play and hot swapping. Its six-wire cable is not only more convenient
than SCSI cables but can supply up to 45 watts of power per port, allowing
moderate-consumption devices to operate without a separate power cord. The
Sony-inspired i.Link usually omits the power part of the cable/connector system
and only uses a 4-pin connector.
