Gefen's ToolBox USB 2.0 Extender Long Range is shipping and we can think of numerous ways in which it could be potentially very useful. The 4-port USB 2.0 hub powers multiple computer devices at up to 100 meters (330 feet) including cameras, scanners, printers, keyboards, hard drives, DVD burners, external storage media, digital signage, and automated control systems. The portable sender and receiver units easily fit into any integrated system with the instant delivery of multiple USB signals over a single CAT-5 cable.
The ToolBox USB 2.0 Extender LR comes in a rugged wall-mountable enclosure, offers locking power supplies to eliminate potential disconnects and can be purchased in a cream or black finish.
Installation is plug and play simple. The computer connects to the sender unit, while the four-port receiver unit connects to the remote peripherals at the remote workstation. A single CAT-5 cable connects sender to receiver, reaching speeds up to 480 Mbps for an instant, long-range signal delivery.
