The Gefen EXT-USB2.0-LR Cat5 USB 2.0 Extender is a transmitter and receiver designed to extend the effective range of connecting USB 2.0 devices to a computer or device. The user connects a USB 2.0 compatible unit into the EXT-USB2.0-LR transmitter which then carries the signal over Cat5 (Ethernet) cable to the EXT-USB2.0-LR receiver, which connects it directly to the controller, whether it's a PC, Mac or other capable peripheral. The maximum range of the extender is 330' (100 m), making it incredibly useful for remote access.
