The X-Dual is a sophisticated extender ideal for dual display extension applications. Convenient and remote control of a PC or KVM switch over 200m of UTP cable, the X- Dual Video is designed with Cat6 in mind. 

Featuring auto bandwidth adjustment and skew reporting for today's challenging Cat6 structured cable systems, the X-Dual is designed to control a PC or KVM switch remotely over UTP cable. The Dual transmits two video signals together with keyboard and mouse to work as either an extender or a video splitter, and is future proof due to flash upgradeability via the keyboard port.
