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. The IEEE 1394-1995 standard for the High Performance Serial Bus defines a serial data transfer protocol. The capabilities of the 1394 bus are sufficient to 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. color of 4-pin 6-pin 9-pin Name Description wire connector connector connector in cable 1

In a regular FireWire cable line A always connected to line B and vice versa (minus to minus, plus to plus). FireWire can connect together up to 63 peripherals in an acyclic network structure (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 U. FireWire also s multiple hosts per bus, and through software IP networks can be formed between FireWire-linked computers. It is designed to 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 moderateconsumption devices to operate without a separate power cord.

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.

Common connectors for different devices and applications IEEE-1394 is based on Apple Computer"s original 1394 bus, which was intended as a low-cost replacement for or supplement to the SCSI bus that is a standard feature of Macintosh and PowerMac computers.
IEEE-1394 Architecture The IEEE 1394-1995 standard defines two bus categories: backplane and cable. The backplane bus is designed to supplement parallel bus structures by providing an alternate serial communication path between devices plugged into the backplane. The cable bus, is a "non-cyclic network with finite branches," consisting of bus bridges and nodes (cable devices). Six-bit Node_IDs allow up to 63 nodes to be connected to a single bus bridge; 10 bit Bus_IDs accommodate up to 1,023 bridges in a system. This means, as an example, that the limit is 63 devices connected to a conventional 1394 adapter card in a PC. Each node usually have three connectors, although the standard provides for 1 to 27 connector per a device"s physical layer or PHY. Up to 16 nodes can be daisy-chained through the connectors with standard cables up to 4.5 m in length for a total standard cable length of 72 m. 1394 truly qualifies as a plug-and-play bus. The 1394 cable standard defines three signaling rates: 98.304, 196.608, and 393.216 Mbps (megabits per second; MBps in this paper refers to megabytes per second.) These rates are rounded to 100, 200, and 400 Mbps, respectively, in this paper and are referred to in the 1394 standard as S100, S200 and S400. Consumer DV gear uses S100 speeds, but most 1394 PC adapter cards the S200 rate. The signaling rate for the entire bus ordinarily is governed by the slowest active node; however, if a bus master (controller) implements a Topology_Map and a Speed_Map for specific node pairs, the bus can multiple signaling speeds between individual pairs. FireWire cables and connectors Standard bus interconnections are made with a 6-conductor cable containing two separately-shielded twisted pair transmission lines for

signaling, two power conductors, and an overall shield. The two twisted pairs are crossed in each cable assembly to create a transmit-receive connection. The power conductors (8 to 40 v, 1.5 a max.) supply power to the physical layer in isolated devices. Transformer or capacitative coupling is used to provide galvanic isolation; transformer coupling provides 500 volts and lower-cost capacitative coupling offers 60 volts of ground potential difference isolation. Connectors are derived from the GameBoy design. Firewire bus details Isochronous or asynchronous data transfers are possible. The isochronous data transport of the 1394 bus provides the guaranteed bandwidth and latency required for high-speed data transfer over multiple channels. On bus reset or when an isochronous node is added to the bus, the node requests a bandwidth allocation. If adequate bandwidth is not available, the requesting device is expected to repeat its request periodically. As an example of bus allocation, video acquisition for non-linear digital editing requires only a single isochronous channel, plus an asynchronous path for device control. IEEE 1394 is a standard, platform-independent solution. Its features represent an evolutionary improvement over current I/O interfaces and provide connectivity solutions for many markets. Legacy I/O bridges attach serial and parallel interfaces to 1394. ANSI SCSI-3 provides a migration path for parallel SCSI to move to IEEE 1394. IEEE 1394 can interface with the higher layers of the new parallel port standard, IEEE 1284. Although IEEE 1284"s 4 to 32 Mbps transfer rate is lower than that of 1394, 1284 finds application in printer connectivity since it is backward compatible with the existing Centronics parallel port. IEEE 1394 devices of differing transport rates may be interconnected, allowing backward compatibility with devices having slower transport rates. This feature allows 100 Mbps devices purchased today to operate properly in future bus configurations involving 200 and 400 Mbps devices.
