Chapter 8: Glossary
8. Glossary
The following terms are commonly used in this guide or in video and KVM technology:
Access: A system to operate a source (computer, CPU) from two consoles.
AES/EBU: Digital audio standard that is officially known as AES3. It’s used to carry digital audio signals between devices.
CATx: Any CAT5e (CAT6, CAT7) cable
CGA: The Color Graphics Adapter (CGA) is an old analog graphic standard that displays up to 16 colors and at a maximum
resolution of 640 x 400 pixels.
Component Video: The Component Video (YPbPr) is a high-quality video standard that consists of three independently and
separately transmittable video signals: the luminance signal and two color difference signals.
Composite Video: The Composite Video is also called FBAS and it is part of the PAL TV standard.
CON module: Component of a DKM Modular Extender or Media Extender to connect to the console (monitor(s), keyboard and
mouse; optionally also with USB 2.0 devices).
Console: Keyboard, mouse and monitor.
CPU module: Component of a DKM Modular Extender or Media Extender to connect to a source (computer, CPU).
DDC: The Display Data Channel (DDC) is a serial communication interface between monitor and source (computer, CPU). It can
exchange data via a monitor cable and the operating system can install and configure a monitor driver automatically.
Dual-Head: A system with two video connections.
Dual-Link: A DVI-D interface for resolutions up to 2560 x 2048 that transmits signals up to 330 MPixel/s (24-bit)
DVI: Digital video standard, introduced by the Digital Display Working Group (http://www.ddwg.org). Single-Link and Dual-Link
standard are distinguished. The signals have TMDS level.
DVI-I: A combined signal (digital and analog) that allows running a VGA monitor at a DVI-I port—in contrast to DVI-D (see DVI).
EGA: The Enhanced Graphics Adapter (EGA) is an old analog graphics standard, introduced by IBM in 1984. It uses a DB9
connector for connection.
FBAS: The analog color video baseband signal (FBAS) is also called Composite Video and it is part of the PAL TV standard.
Fiber: Single-mode or multimode fiber cables.
KVM: Keyboard, video and mouse.
Mini-XLR: Industrial standard for electrical plug connections (3-pole) for the transmission of digital audio and control signals.
Multimode: 62.5µ fiber cable or 50µ fiber cable
OSD: The on-screen-display displays information or operates a device.
Quad-Head: A system with four video connections.
RCA (Cinch): A non-standardized plug connection that transmits electrical audio and video signals, especially with coaxial cables.
SFP: Small Form Factor Pluggable (SFPs) are pluggable interface modules for Gigabit connections. SFP modules are available for
CATx and fiber interconnect cables.
Single-Head: A system with one video connection.
Single Link: A DVI-D interface that supports resolutions up to 1920 x 1200 by transmitting signals up to 165 Megapixels per
second (24-bit). Alternative frequencies are Full HD (1080p), 2K HD (2048 x 1080), and 2048 x 1152.
Single-mode: 9µ fiber cable
