2. Overview
2.1 Introduction
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 (see Figure 1). Local units offer dual access, allowing the connection of
a second user console close to the computer. With the optional upgrade kit, you can also use
ACS253A units to communicate stereo audio and serial port signals.
The ServSwitch

Brand DVI KVM Extender Series enables high-resolution video, PS/2
keyboard and mouse signals to be communicated up to:
•
300ft (100m) over Category 5, 5e, 6 or higher (CATx) cable.
•
1200ft (400m) over Multimode fiber cable (50/125µ).
•
600ft (200m) over Multimode fiber cable (62.5/125µ).
•
6¼ miles (10km) over Singlemode fiber cable (9/125µ).
In a digital application (DVI input and output), there is no loss of picture quality irrespective
of extension distance and no adjustments are required. The DVI KVM Extender Series also
supports traditional analog VGA as well as digital DVI. All combinations of DVI and VGA
(graphics cards and monitors) are supported, allowing equipment to be mixed. In a mixed
analog/digital application, some adjustment of the video signal is necessary to optimize the
analog-digital signal conversions. DVI KVM Extenders are equipped with various automatic
and manual video correction tools in an on screen utility (see page 28).
