System Requirements
PC: IBM PC/AT with IEEE1394 port
OS: MS Windows 2000 upgraded with Service Pack 1 (minimum)
Cable length: 4.5m (15ft)
6.6.2 IEEE1394 SCSI PRINT
IEEE1394, also known as FireWire (a name patented by Apple), is an easy-to-use
peer-to-peer networking technology allowing speeds of up to 400 Mbps.
The current standard contains the following features, which are supported in most
devices:
•
Hot swapping (cables can be connected and disconnected while the
computer and other devices are switched on)
•
Peer-to-peer networking (no hub required)
• No terminator or device ID is required, unlike SCSI
•
Automatic configuration of devices upon start-up, or “plug and play.”
•
Real-time data transfer at 100, 200, and 400 Mbps
•
Common connectors for different devices
The cable length is limited to 4.5 m (15ft). However, up to 16 cables and 63
devices can be connected to an IEEE1394 network.
IEEE1394 cables can be either 4-pin (data only) or 6-pin (data and power).
IEEE1394 allows either 6-pin or 4-pin connectors. However, this machine only uses
the 6-pin style connector. The machine has two 6-pin ports.
