The following terms are commonly used in this manual or in video and KVM technology.
Term
Description
AES/EBU
Interface specification for the transmission of digital stereo, two-channel, or mono audio
signals between different devices according to the AES3 standard.
Cat X
Any Cat 5e (Cat 6, Cat 7) cable.
CON Device
Logical object that summarizes several EXT Units of physical extender modules (CON
Units) to switch more complex sink systems via matrix.
CON Unit
Decoder extender module to connect to the console (monitor(s), keyboard, and mouse;
optionally also with USB 2.0 devices).
Console
Monitor, keyboard, mouse, media control, external switching solution, etc.
CPU Device
Logical object that summarizes several EXT Units of physical extender modules (CPU
Units) to switch more complex source systems via matrix.
CPU Unit
Encoder extender module to connect to a source.
Dual-Head
A system with two video ports.
EDID
Extended Display Identification Data (EDID) is a metadata format (128 Byte) for display
devices to describe their capabilities to a video source (e.g., graphics card).
Fiber
Single-mode or multi-mode fiber cables.
KVM
Keyboard, video, and mouse.
LPCM
LPCM (Linear Pulse Code Modulation) is a pulse modulation method, also known as an
uncompressed data format. The LPCM method is used for converting analog audio into
digital audio with evenly large value ranges.
Mini-DisplayPort
A VESA standardized interface for an all-digital transmission of audio and video data. It is
differentiated between the DisplayPort standards 1.1 and 1.2. The signals have LVDS
level.
Mini-XLR
Industrial standard for electrical plug connections (3 pole) for the transmission of digital
audio and control signals.
MTBF
Mean Time Between Failure (MTBF) is measured in power-on hours and describes the
system reliability.
Multi-Mode
50 µm multi-mode fiber cable.
RCA (Cinch)
A non-standard plug connection for transmission of electrical audio and video signals,
especially with coaxial cables.
S/PDIF
Interface for electrical or optical transmission of digital stereo audio signals between
different devices used in consumer electronics.
SFP
SFPs (Small Form Factor Pluggable) are pluggable interface modules for Gigabit
connections. SFP modules are available for Cat X and fiber cables.
Single-Head
A system with one video port.
