INTRODUCTION
FireWire is a method of transferring information between digital
devices, especially audio and video equipment.
You can connect up to 63 devices to a FireWire bus. Windows
operating systems (98 and later) and Mac OS (8.6 and later)
both support it.
FireWire 400 sockets
FireWire 400 connector

7. FireWire
IEEE1394 or 'fireWire' is a high speed serial
bus
Up to 400 Mbps
Multiple devices on a bus
Up to 10m between devices or repeaters

Standard on most new PCs

HISTORY AND 
DEVELOPMENT
Apple intended FireWire to be a serial replacement for the 
parallel SCSI (Small Computer System Interface) bus while 
also  providing  connectivity  for  digital  audio  and  video 
equipment. 
Apple's development of the original IEEE 1394 was completed 
in 1995.
It was followed by several modifications: 
The IEEE Std. 1394a­2000, the IEEE Std. 1394b­2002, and the 
IEEE Std. 1394c­2006 amendment. 
The aim of current work in Sony's version of the system is 
known as i.LINK, and uses only the four signal pins, omitting 
the two pins which provide power to the device because of a 
separate power connector on Sony's i.LINK products

10. FireWire
The designers of FireWire had goals in mind
when they created the standard:
Fast transfer of data
Ability to put lots of devices on the bus
Ease of use

Provision of power through the cable

Plug-and-play performance
Low cabling cost

FIREWIRE 
SPECIFICATIONS
FireWire 400 (1394a), was faster than USB when it came out.
FireWire 400 is still in use today and features:
Transfer rates of up to 400 Mbps
Maximum distance between devices of 4.5 meters (cable length)
FireWire 800 (1394b) started showing up in consumer devices.
FireWire 800 is capable of:
Transfer rates up to 800 Mbps
Maximum distance between devices of 100 meters (cable length)
The faster 1394b standard is backward-compatible with 1394a.

12. FireWire
FIREWIRE VS. 
USB
The  key  difference  between  FireWire  and  USB  is  that 
FireWire is intended for devices working with a lot more 
data  ­­  things  like  camcorders,  DVD  players  and  digital 
audio equipment. 
As you can see, the two are a lot alike.
which  led  to  the  adoption  of  USB  as  the  standard  for 
connecting  most  peripherals  that  do  not  require  a  high­
speed bus. 
FireWire  is  peer­to­peer,  meaning  that  two  FireWire 
cameras  can talk  to each  other without  going through a 
computer.

FIREWIRE CABLES AND 
CONNECTORS
FireWire devices can be powered or unpowered. FireWire allows
devices to draw their power from their connection.
Two power conductors in the cable can supply power (8 to 30
volts, 1.5 amps maximum) from the computer to an unpowered
device.
Two twisted pair sets carry the data in a FireWire 400 cable using
a 6-pin configuration.

15. FireWire
Some smaller FireWire­enabled devices use 4­pin connectors 
to save space, omitting the two pins used to supply power. 
FireWire 800 cables use a 9­pin configuration. Six of those 
pins are the same as the six pins in the 1394a connector 
(shown below). 
Two of the added pins provide a "grounded shield" to protect 
the other wires from interference, and the third added pin 
does nothing at this time. 
FIREWIRE CABLES AND 
CONNECTORS

16. FireWire
FireWire uses 64-bit fixed addressing, based on the IEEE 1212 standard.
There are three parts to each packet of information sent by a device over FireWire:
1.A 10-bit bus ID that is used to determine which FireWire bus the data came from
2.A 6-bit physical ID that identifies which device on the bus sent the data
3.A 48-bit storage area that is capable of addressing 256 terabytes of information
for each node
For example :-
It takes four hops for Computer C to access the camera. Assuming all of the devices
in this setup are equipped with FireWire 800, the camcorder can be up to 400 meters
from Computer C.

FIREWIRE AND DIGITAL 
VIDEO
FireWire really shines when it comes to digital video applications. When you attach a
camcorder to a computer using FireWire, the connection is amazing.
An important element of FireWire is the support of digital devices. In data streams
between the device and the host in real-time with Guaranteed bandwidth and no error
correction.
When the computer-to-camera through FireWire, the camera can send the video in a
steady flow to the computer without anything disrupting the process.
You can easily edit and create custom video projects using fast hard drives, a digital
camcorder and a computer.

FURTHER APPLICATIONS AND 
THE FUTURE OF FIREWIRE:
The IEEE 1394b spec can be used in airplanes to connect the 
video source with each passenger's in­seat built­in monitor. 
With CPUs not being very efficient at streaming media and 
data. 
FireWire 400 has the ability to handle hundreds of channels 
of noise free digital audio and up to 256 channels of MIDI. 
FireWire 800 can handle twice as many real­ time streams.
The 1394b provides significant amounts of bus power (up to 
25  watts)  drive  users  with  portable  computers  and 
peripherals that want to use casual storage will not need a 
battery­powered drive.

don’t make sense unless they link.”
Its time for a small Demo…
