Apple FireWire Card

The optional Apple FireWire Card is designed to work with digital video camcorders and decks

that use the DV format and have a FireWire port (sometimes marked IEEE 1394 or DV IN/

OUT). The included hardware and software, together with a nonlinear editing application,

allow you to capture DV movie clips to your hard disk. You can view the clips in MoviePlayer or

other QuickTime 3.0 applications, and edit and render the DV movies. If you are using a video

editing application with an export function, you can send (print or record) movies back to the

tape in your camcorder or deck. The software also allows the FireWire device to be controlled

from the computer.

The FireWire Bus

FireWire is a serial bus that can support high-performance devices, such as DV cameras and

printers. Devices can be connected in any combination of branching and chaining, as long as

no loops are formed. A FireWire bus can support up to 16 consecutive cable hops of 4.5 meters

each. There are no SCSI-style ID numbers to set and no termination requirements.

The Apple FireWire Card is designed to keep the network alive even if the Macintosh is shut

down. Loss of power to the Macintosh will not affect the operation of a FireWire card as long as

it can draw power from other cards on the bus.

Each card provides power which is available to other devices on the network. This means that

a system shutdown will not result in interrupted transmission over a FireWire network.

Apple FireWire Hardware

If you ordered the Apple FireWire Card with your computer, you have received the following

items:

m the Apple FireWire Card, installed in one of your computer’s PCI slots

m a FireWire cable, 4-pin to 6-pin, 2 meters long

m a FireWire software installation CD

Your Apple FireWire Card has three FireWire ports, as shown in the following illustration.
