Main Features
This section has some general information about 1394 or “FireWire” technology and
features specific to the two models of the card.

What is IEEE 1394
The 1394 standard was defined, and continues to be maintained, by the Institute of
Electrical and Electronics Engineers, Inc. (IEEE). The technology allows for high-speed
connections between computers and related devices and helps bridge the divide between
computers and consumer electronics. The technology is flexible, easy to use and offers
high bandwidth at a low cost.
With 1394-compatible products and systems, users can transfer video or still images from
a camera or camcorder to a printer, PC, or television quickly, with no image degradation.
1394 Features
The 1394 standard is a high-speed serial bus designed to deliver high data transfer speeds
at a low cost, and with the low degree of latency required by a peripheral bus or by a
backup to a traditional parallel bus. Among its key features are:
High Speed.

The 1394U and the PC System
The I394U is a host controller card with a PCI interface. It comes with three independent
IEEE1394 bus ports, each of which can transfer data at 400Mbps. When you plug an
IEEE 1394/FireWire device into one of the card’s three ports, Windows 98 will
automatically install the new device and the appropriate driver. With its hot-plug support,
you can easily connect or disconnect devices without having to first shut down your
computer. This enables true Plug-and-Play functionality.
