What Is FireWire?

Computer Advice | September 9, 2010 | 1 Comment

One of the best and fastest ways to transfer digital information is via FireWire. Because it is very fast, it was quickly adopted by people working in video and audio as they deal with large files on a daily basis. Currently FireWire can transfer at speeds up to 800 Mbps, but plans are in the works for a version that will transfer at a whopping 3.2 Gbps.

Also known as IEEE 1394, FireWire was originally developed by Apple as simply a high speed bus. Like USB, it is plug and play and p to sixty three devices can be connected at once a daisy chain (see example video below). Devices can be plugged and unplugged at any time without causing damage because FireWire devices are hot pluggable. While this is a benefit, it’s main selling point is the high bandwidth transfers it provides.

Firewire Cable

Nearly all digital camcorders have included a FireWire 1394 interface. This provides much faster transfer rates than USB 2.0. Though USB is currently more common, this is due to change. If you are currently shopping, or will be shopping for a new computer, look for one with FireWire ports. Technically superior, it is set to overtake USB with it’s benefits and speed. If the specifications are unclear take the time to contact the manufacturer.

To determine if you currently have any FireWire ports take a quick look at your computer. These ports will be located next to USB ports but are smaller in size. The ports are rectangular in shape. They are angled on one side, and have four to six “teeth” inside.

You will need to have the appropriate cable for your ports. A six pin to six pin cable will draw it’s power from the FireWire bus, and is most commonly used for CD-RW’s and hard drives. A six pin to four pin cable does not draw power from the bus, and is generally used to connect cameras and other devices that power themselves. Four pin to four pin cables are also available. A nine pin connector exists, but is mostly reserved for professional equipment. The largest cable on the market is 14.8 feet in length. To connect cable for further reach, another hub repeater will be required. This will allow you to couple cables together.

If you will not be purchasing a new computer soon and do not currently have FireWire capability, don’t fret. It can be installed. To add FireWire to your desktop use a PCI adapter. For a laptop, a notebook adapter will do the trick. Older computers are not as easy, but can be updated. A mother board replacement to a card compatible version will be required. Versions of Windows that are 98 or later, and 8.6 Mac or later can support FireWire.

Should your device not be recognized, try shutting down and restarting it. Unplug the power to the computer as well as the FireWire drive. Leave the power off for at least ten minutes. Reconnect and reboot. This usually solves the problem.
