A bilingual cable allows the connection of older devices to the newer port. The full IEEE 1394b specification supports data rates up to 3200 Mbit/s (i.e., 400 megabytes/s) over beta-mode or optical connections up to 100 metres (330 ft) in length. Apple's implementation on laptops is typically related to battery power and can be as low as 9 V.įireWire 800 was introduced by Apple in 2003, allows an increase to 786.432 Mbit/s with backwards compatibility to the slower rates and 6-pin connectors of FireWire 400. However, while the IEEE 1394a and IEEE 1394b standards are compatible, FireWire 800's connector, referred to as a beta connector, is different from FireWire 400's alpha connectors, making legacy cables incompatible. Typically a device can pull about 7 to 8 watts from the port however, the voltage varies significantly from different devices. Voltage is specified as unregulated and should nominally be about 25 volts (range 24 to 30). The 6-conductor powered connector, now referred to as an alpha connector, adds power output to support external devices. Cable length is limited to 4.5 metres but up to 16 cables can be daisy-chained yielding a total length of 72 meters under the specification.
(Sony-inspired iLink usually deletes the power part of the cable/connector system and only uses a 4-pin connector.) Firewire standardsįireWire 400 (IEEE 1394-1995, IEEE 1394a-2000)įireWire 400 can transfer data between devices at 100, 200, or 400 Mbit/s data rates (actually 98.304, 196.608, or 393.216 Mbit/s, but commonly referred to as S100, S200, and S400). 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. It is designed to support plug-and-play and hot swapping.

FireWire also supports multiple hosts per bus, and through software IP networks can be formed between FireWire-linked computers. 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. In a regular FireWire cable line A always connected to line B and vice versa (minus to minus, plus to plus).įireWire can connect together up to 63 peripherals in an acyclic network structure (as opposed to SCSIs linear structure). Ground return for power and inner cable shield The capabilities of the 1394 bus are sufficient to support a variety of high-end digital audio/video applications, such as consumer audio/video device control and signal routing, home networking, nonlinear DV editing, and 32-channel (or more) digital audio mixing.

The IEEE 1394-1995 standard for the High Performance Serial Bus defines a serial data transfer protocol.
FireWire (also known as i.Link or IEEE 1394) is a personal computer / consumer electronic serial bus interface standard offering high-speed communications and isochronous real-time data services.
