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
