2. Overview

Introduction

The SDMX PS/2 Mini Extender Series enables two channels of high-resolution

video, PS/2 keyboard and mouse, and, optionally, stereo audio and serial port

signals to be communicated up to 50m over CATx (Category 5, 5e, 6 or higher)

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 monitors) attaches to the Remote Unit. The Remote and Local Units

communicate video and data information along the connecting CATx cables

(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.
