FireWire Ports

The iMac has two external FireWire IEEE 1394 ports. The features of the FireWire ports are:

• Support serial I/O at 100, 200, and 400 Mbps (megabits per second)
• Share 6 watts of power (8 W peak) when the computer system is on
• Support up to 62 devices

The FireWire hardware and software provided with the iMac are capable of all asynchronous and isochronous transfers defined by IEEE standard 1394.

Developers of FireWire peripherals are required to provide device drivers. A driver for DV (digital video) is included in QuickTime, which comes installed on the iMac. A driver for mass storage devices is included in the system software.
