CARD-32-IOI is a dual-port OHCI-compliant IEEE-1394 CardBus adapter featuring Texas Instruments OHCI-Compliant IEEE 1394 Host Controller and Texas Instrument\'s TSB41AB2 PHY. It functions at the maximum IEEE-1394 speed of 400 Mbps. It allows up to 63 devices to be connected in chain through its two external 6-pin ports. CARD-32-IOI is particularly great for use with multimedia and storage peripherals such as DV camcorders, disk drives, and ultra high resolution scanners, printers and digital still cameras for professional applications. FEATURES of IEEE 1394: IEEE-1394 is aimed at higher-speed multimedia peripherals such as video camcorders, music synthesizers, DVCR, DVD/CD ROM, CD-RW, scanner, camera and hard disks. IEEE-1394 offers incredible convenience through "hot plug" capability, eliminating any need to turn off or restart the computer when attaching a new peripherals. IEEE-1394 is ease of use. It also features automatic configuration, jumpers, DIP switches, screws, latches, terminators, simple-to-use cables, and, no device IDs needed. IEEE-1394 supports up to 63 devices using cable lengths up to 14 feet (about 4.5m). It provides it\'s own bus power, enabling peripherals to be even simpler. It is cross-platform industry standards. BENEFITS of IEEE 1394: You can bring video images directly into your computer over a IEEE-1394 connection as a perfect digital copy with no conversion losses. IEEE-1394 is a peer-to-peer technology. You can connect other systems on the same IEEE-1394 bus. It provides High Speed Local Area Networking at 400Mbps. Plug-and-Play networking in tree topology. No hubs, hassles, and terminators are needed or used. Host Bus Type II CardBus 1394 Bus Transfer Rate 100/200/400 Mbps Link Controller TI OHCI Compliant IEEE1394 Host Controller 1394a PHY PHY: TI.
