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 DDXI DVI/VGA KVM
Extender units to communicate stereo audio and serial port signals.
DDXI DVI/VGA 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 DDXI
DVI/VGA 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. DDXI DVI/VGA KVM Extenders are equipped with various automatic
and manual video correction tools in an on screen utility (see page 25).
