5m 6 pin - 4 pin Firewire CableHigh quality Firewire cable, allowing you to get the full benefit of the performance available from Firewire connectivity.
A comparable Apple 6 pin - 4 pin Firewire Cable for an Apple iPod uses part numbers M8635G/B and M87066A.
For charging an iPod a 6 pin to 6 pin cable is required. A 6 pin to 4 pin cable with 4-6 adapter will not be sufficient.
Features and benefits:-
- Gold plated contacts interface on 2mm centreline.
- Cable conductors 22-24, 28-30 AWG.
- Receptacle half SMT or Thru-hole.
- 6 position connector: 4 signal, 2 power.
- Power contacts mate before signal contacts.
- 1500 cycles minimum durability.
- Positive latching.
- High performance Universal I/O with data rates up to 400 Mbps.
- Plug and Play.
- Compressed/uncompressed video support.
- Hot pluggable.
Applications:-
- Portable computing.
- Desktop PCs and peripherals
- Desktop File Servers.
- Video conferencing, editing, playback.
- Consumer electonics, camcorder, VCR, Set-tops.
- Mass storage systems.
Typical cable uses are as follows:-
6 pin - 4 pin for device to host card connection (the most common cable required).
6 pin - 6 pin Firewire Networking (Mac-Mac or Win XP û Win XP Only) or Apple iPod charging
4 pin - 4 pin for device to device connection.
The History of FirewireFireWire (IEEE 1394) is a personal computer and digital video serial bus interface standard offering high-speed communications and isochronous real-time data services, developed primarily by Apple Computer, completing development in 1995. It is defined in IEEE 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. Sonys 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 Sonys i.Link products.
The system is commonly used for connection of data storage devices and digital video cameras, but is also popular in industrial systems for machine vision and professional audio systems. It is used instead of the more common USB due to its faster speed, higher power distribution capabilities, and because it does not need a computer host. It also has native support for isochronous data transport (data that must be delivered with deterministic latency, such as audio or video). However, the small royalty that Apple Computer and other patent holders has initially demanded from users of FireWire and the more expensive hardware needed to implement it has prevented FireWire from displacing USB in low-end mass-market computer peripherals where cost of product is a major constraint.
It can connect together up to 63 peripherals in a non-cyclic network structure (as opposed to SCSIs 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, and through software IP networks can be formed between Firewire-linked computers. 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. (Note that the Sony-inspired iLink usually deletes the power part of the cable/connector system and only uses a 4-pin connector.)
FireWire 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). 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.
FireWire 800 (Apples name for the 9-pin ""S800 bilingual"" version of the IEEE1394b standard) was introduced commercially by Apple in 2003, and allows an increase to 786.432 Mbit/s with backwards compatibility to the slower rates and 6-pin connectors of FireWire 400.
The full IEEE 1394b specification supports optical connections up to 100 metres in length and data rates up 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 than USB 2.0.
Almost all modern digital camcorders have included this connection since 1995. All Macintosh computers currently produced have built-in FireWire ports, as do all Sony PCs and many PCs intended for home or professional audio/video use. FireWire is also used on the iPod music player, permitting new tracks to be uploaded in a few seconds and also for the battery to be recharged concurrently with one cable.
