2.1 Introduction

The ServSwitch Brand CATx KVM Extender Series enables high-resolution video, PS/2
keyboard and mouse, stereo audio, and serial port signals to be communicated up to 1000ft
(300m) over Category 5, 5e, 6 or higher (CATx) cable.
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
connecting CATx cable (see Figure 1).
Within the product range, models are available with combinations of the following:
• Audio transmission: bi-directional stereo audio (16-bit digitized).
• Serial transmission: transparent serial COM port (to 19.2Kbps).
• Dual access: allowing a second user console at the Local unit.
