Simultaneous Operation of Multiple High-performance Devices. Supports Hot-swapping and Plug-and-Play Connection of Peripheral Devices. Fully Interoperable with FireWire, , and SB1394 Implementation of IEEE 1394 Standard. Works with Types of FireWire 800 (1394b) and 1394a Devices Including Portable Hard Disk, DV Camcorder, Digital Camera, CD-RW/DVD-ROM Drive and Other Audio/Video Devices. 1- (x1) PCI-Express with Transfer Rate 2.5Gb/s Full Duplex Channel. Support Provisions of IEEE P1394b Revision 1.33+. Compliant with PCI-Express Revision 1.0a. Compliant with IEEE 1394 OpenHCI Specifications V1.1 and V1.2.Compliant with IEEE 1394-1995 for a High Performance Serial Bus. Compliant with IEEE 1394a-2000 Standard. Widely Compatibility: 10/ 8 / 7 / Vista / XP / 2000 / ME / 98SE / Server 2003-2008 32/64-bit, for .Supports Data Transfer Rates of: 100Mbps/200Mbps/400Mbs/800Mbps. 1394b controller card compliants with IEEE 1394b standard, transmission speed of up to 800Mbps, and also in line with IEEE 1394-1995 and IEEE 1394a-2000. The PCI-Express bus transmission speed of 2.5Gbps, far higher than the PCI bus, fully shows high-speed transmission performance of IEEE 1394b, and is backward compatible with devices in 400/200/100Mbps transmission speed.
