Double your data speed with IEEE 1394b. The FW-P03T, FireWire800 1394b PCI card, offers IEEE 1394 users nearly double the data throughput (up to 800Mbps) of the original IEEE1394 specification. IEEE 1394b delivers a dramatic performance gain while maintaining backward compatibility with the original IEEE 1394 standard, enabling continued use of older IEEE 1394 devices alongside the latest ultra-fast IEEE 1394b peripherals. 1394 bus power allows you to utilize the repeater feature even when the computer is powered off. With two 9-pin IEEE 1394b ports and one conventional 6-pin IEEE1394a port the FW-P03T combo PCI card offers the best of both worlds. Provides two backward compatible 1394b ports at up to 800 Mbps, and one 1394a-2000 fully compliant port at 100/200/400 Mbps. Fully Interoperable with Firewire", i.Link" and theSB1394", implementation of the IEEE 1394 standard. Compliant with PCI Bus Power Management Spec. V1.1. Supports 33MHz 32/64-bit selectable universal PCI interface. Support for digital video in full size, full motion video of 720 x 480 pixels at 30 frames per second. Support Plug-n-Play and Hot-Swap connection of IEEE 1394 (FireWire) peripheral devices. Supports up to 62 daisy-chained external FireWire devices. Provide power source to 1394 bus by PCI bus and 4-pin mini housing power connecting. Powered repeater feature through 1394 bus. 9-pin to 9-pin 1394b cable and 9-pin to 6-pin Firewire cable for options. *For Microsoft Windows 98SE, ME, 2000, operation speed is up to 400Mbps. *For Windows XP, operation speed is able to up to 800Mbps, pending Microsoft 1394 driver release. *For Mac OS 8.6-9.x or OS 10.1.x -10.2.3, operation speed is up to 400Mbps. *For Mac OS 10.2.4 or newer, operation is up to 800Mbps
