Description

Unibrain's 3 Port Repeater Hub provides port expansion on FireWire® 800 IEEE 1394b device chains. The platform agnostic device provides three 9 pin (bilingual) IEEE 1394b ports with a maximum throughput of up to 800 Mbps each. The Hub utilizes IEEE 1394b bus power, or accepts an optional power adapter for use with devices requiring more power. Repeater hubs provide bus flexibility in that they allow for daisy chaining and/or hierarchical (tree) bus configurations. Repeater hubs also provide a means to lengthen the distance between devices when 1394's cable length of 4.5 meters (15 feet) is inadequate. Simply daisy chain repeaters between cables to extend your reach to 110m.
