IEEE-1394a Connectors
The optional IEEE-1394 interface addresses interconnection of both computer
peripherals and consumer electronics with these features:
•
IEEE-1394a operation
•
Support for up to 63 peer-to-peer devices
•
Operation ranging from 100 Mbits/sec to 400 Mbits/sec (depending on cable type)
•
