This PCI-Express IEEE 1394b FireWire Controller Card is designed base on the advance technology of IEEE 1394b standard with transfer rate up to 800Mbps, it is also compliant with IEEE 1394-1995 and IEEE standard 1394a-2000. Having the speed of the transfer rate up to 2.5Gbps per Lane of the latest PCI-Express technology, the bottleneck of the speed of the PCI interface can be eliminated. With the capability of backward compatible to 400/200/100M bps, it is an ideal platform for connecting the exiting 1394a or 1394b mass storage devices with its ultimate high speed, it is also perfect for video capturing and audio data transferring. Furthermore, the controller card allows 2 or more computers connected together via the firewire ports to form a simple local area network.Low profile metal bracket to fit small form factory HTPC caseTI XIO2213 Chip set1-Lane (x1) PCI-Express with transfer rate 2.5Gb/s Full Duplex channelCompliant with PCI-Express Revision 1.0aSupport provisions of IEEE Standard P1394b-2002Compliant with 1394 Open Host Controller Interface (OHCI) specification Revision 1.1 and 1.2 draftSupport 800 / 400 / 200 / 100Mbps transfer rateFully Plug & Play and Hot Plug supportedFully backward compatible to 1394a specificationCompliant with IEEE 1394a-2000 and 1394-1995 standard for a High-Performance Serial BusFully interoperable with FirewireTM , iLINKTM and SB1394TM implementation of IEEE 1394 standardEquipped with Bilingual IEEE Standard 1394b-2002 ports for 800Mbps data transferringBuilt in driver support from Windows 7 / Vista / XP / 2000 / Server 2003-2008 32/64-bit, Mac operating systemLow profile metal bracket to fit small form factory HTPC case1 x 1394 adapter1 x Standard height metal bracket
