2. Overview
2.1 Introduction
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.
