The VIA VT6306 controller is a complete single chip IEEE 1394a
solution. It is fully compliant with the 1394a OHCI (Open Host
Controller Interface) 1.1 specification. 1394a is a fast external bus
standard that supports data transfer rates of up to 400Mbps. In
addition to its high speed, it also supports isochronous data trans-
fer which is ideal for video devices that need to transfer high
levels of data in real-time. 1394a supports both Plug-and-Play and
hot plugging allowing devices to be attached or removed from
the system, even with the power on.
One card-edge bracket, mounted with 3 IEEE 1394a ports, will be
provided as an option. Install the card-edge bracket to the system
chassis then connect the cable connectors to J2, J13 and/or J14.
Make sure pin 1 of the cable connectors is aligned with pin 1 of
J2, J13 and/or J14. Now connect your 1394a devices to the 1394a
por ts that are on the bracket.
