The U22-160-DP extends your host PC’s USB 2.0 port across a single Cat5e/6 cable to 50 meters (165 ft) with data rates up to 480 Mb/s. In most instances, no power supply is needed for either side as the local (host) side gets its power from the PC and it sends PoC (Power-over-Cable) to the remote (device) side. However for convenience a power supply is included that can be plugged in to the remote end for power hungry USB devices. The local side is in a convenient single-gang Decora® wall-plate. The remote end has a two port hub built-in to allow connection of 2 USB Devices. The U22-160-DP is a perfect solution for industrial and commercial applications. This product can be used to extend a broad range of USB devices like webcams, printers, keyboards, and disk drives up to 165 ft (50 m) using single Cat 5/6 cable
