The following terms are commonly used in this manual or in video and KVM technology.
Term
Description
ACK
Since packet transfer is not reliable, a technique known as positive
acknowledgment with retransmission is used to guarantee reliability of packet
transfers.
API
An application programming interface (API) is a specification intended to be
used as an interface by software components to communicate with each other.
An API may include specifications for routines, data structures, object classes
and variables.
Cat X
Any Cat 5e (Cat 6, Cat 7) cable
Console
Keyboard, video and mouse
Echo
The response of the Draco MV to an external command (optional).
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).
DDC
Display Data Channel (DDC) is a serial communication interface between
monitor and source. DDC enables data exchange via monitor cable and an
automatic installation and configuration of a monitor driver by the operating
system.
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.
Dual-Head
A system with two video connections.
HDMI
An interface for an all-digital transmission of audio and video data. It is
differentiated between the HDMI standards 1.0 to 1.4a, also 2.0 to 2.0b or 2.1.
The signals have TMDS level.
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.
MSC
Control of USB-HID of up to four sources at one sink with only one connected
mouse or keyboard. The sink can consist of up to two monitors, or up to four
monitors when operating Dual-Head sources.
MTBF
Mean Time Between Failure (MTBF) is measured in power-on hours.
Multi-Screen Control
Control of USB-HID of up to four sources at one sink with only one connected
mouse or keyboard. The sink can consist of up to two monitors, or up to four
monitors when operating Dual-Head sources.
OSD
The On-Screen-Display is used to display information or to operate a device.
PCM
PCM (Pulse-Code-Modulation) is a pulse modulation method, also known as an
uncompressed data format. The PCM method is used for converting analog
audio into digital audio.
POH
Power-on hours corresponds to the average operating time
S/PDIF
Interface for electrical or optical transmission of digital stereo audio signals
between different devices used in consumer electronics.
Single-Head
A system with one video connection.
