2.1Introduction

A Cat5 KVM Extender is mainly used, to extend the maximum distance between a CPU and his Keyboard / Monitor / Mouse considerably. In addition they are irrecoverable in installations in electromagnetic hazardous environments (EMI). Normal Keyboard-/ Monitor-/ Mouse extender cables (and Extender using traditional cables) cannot go so far and EMI interferences may reduce the maximum distance and/or reliability. Using a DVI-D Cat X Extender system, these limitations are past. Remain your CPU in a secure rack cabinet or data center while accessing from a 140m remotely located place.

A basic KVM extension system comprises a Local unit (transmitter) and a Remote unit (receiver). The Local unit connects directly to the computer (or a KVM switch system) using the supplied cable(s). The user console (keyboard, mouse and monitor) attaches to the Remote unit. The Remote and Local units communicate video and data information along the interconnecting cable. Local units offer dual access, allowing the connection of a second user console close to the computer.
