Icron’s OEM ExtremeUSB® 1.1 products operate over standard solid core Cat 5e UTP cable (the same wiring used in Ethernet). The USB RV2850 uses technology ideal for extending USB peripherals without the need for additional software for either the computer or the target devices.

The USB RV2850 product is composed of two separate units: the Local Extender and the Remote Extender. Conventional USB cables are used to connect the Local unit to the host computer, and the remote USB device to the Remote unit. Cat 5e UTP cabling is used to connect the Local and Remote units over a distance of up to 85m (279 ft).

Icron’s USB 1.1 RV2850 extension system is a 2-port extender, ideal for use with USB peripherals such as keyboards, mice, interactive white boards (including SMART Boards and Promethean ActivBoards), and game controllers without the need for external power adapters. Product is sold as unbranded or available for private label.
