How many FireWire devices can I connect at any one time?

How many FireWire devices can be connected at any one time? To answer this, we will take a look at what firewire is and does, as well as how many devices can be connected at one time.

FireWire is the brand name for Apple's high-speed data serial bus that they developed, which is also known as IEEE-1394. This digital interface technology can transfer data at up to 400 megabits per second . FireWire 800 is a more recent version of this standard, and is capable of speeds up to 800 megabits per second. Normal common uses for FireWire include webcams, data transfers with external hard drives, DV camcorders, and the iPod digital music player by Apple.

FireWire 800 is among the quickest, if not the quickest general purpose interface you can find. FireWire 800 can reach speeds of up to 800 megabits per second, which allows for the transfer of huge amounts of information in a very short time, which is common sense today due to the size of some files that are commonly being backed up and manipulated. Higher transfer speeds also means the ability to work directly from an external drive without having a drop in performance, something that is usual if you work with large files stored on USB volumes.

Multispeed is also supported by FireWire. FireWire devices exist that transfer data at speeds from 100 to 800 megabits, depending on their quality, age, ,and purpose. All these speeds can be mixed on one single bus and all the devices will still operate at maximum speed, due to the fact that the interface has the ability to change speeds on a packet by packet basis.

FireWire is operable over long distances, up to 100 meters, opening up unheard of possibilities that are not possible with other technologies. FireWire also givess plenty of power to the devices that are connected to it. FireWire can supply up to 45W of power, which is more than other ports. This means there are less power bricks that can catch fire, less cables to deal with, devices that charge and sync at the same time, and, because the power is significant, this means no cutting down on on-device screens, disk speeds, or even status lights. A choice does not have to be made between portability and features, which other interfaces may usually require. Most of the self-powered drives, like the iPod, the iSight, and dozens of other great gadgets would not be around if it weren't for the power of FireWire. FireWire is creating peer-to-peer networks, and it has always done so, which means devices have the ability to talk to each other without requiring the use of a computer, even on complex chains. This feature has been available since FireWire was first created, which means that all FireWire devices were built with this ability in mind, while other general purpose interfaces were not built with this in mind.. The ability to be able to pull a cable between two camcorders and copy the data from one onto the other is a great benefit.

FireWire can move the streaming data in real time, by putting an emphasis on the speed and fluidity. FireWire is used on TVs, set-top boxes, professional audio equipment, or anything else that may require streaming to work very well. In this type of case, FireWire will guarantee the bandwidth to some devices, and manage the resources that are allocated to other peripherals on the chain. This allows them to work at the best possible speed without allowing the bandwidth to drop below what the broadcast link requires.

FireWire was designed for efficiency regardless of how many devices are on the chain. While the performance of other interfaces will degrade quickly, with FireWire the data transfer continues undisturbed by all the link traffic. A good example is the fact that FireWire can read and write to memory without the Mac's CPU getting involved, because FireWire draws surprisingly few resources.

One of the biggest advantages to FireWire is that it is fully autoconfigurable. The devices are placed on a peer-to-peer chain, they communicate with each other, and pretty much mind their own business together with the others. As long as higher protocol requirements are met, like the mounting and unmounting drives, and sufficient power is provided to the chain, the theory is that expansion is limitless without the devices having a malfunction or meltdown.

To answer the question of how many devices can be connected at once, FireWire has the capability to be connected to up to 63 devices on a bus. The amount of power that is available from the computer, as well as the amount of power required by the devices, determines the number of bus powered devices that can be connected.
