KeyGroup
KeyGroups provide a way of assigning a label to multiple panels simultaneously even
within a networked matrix system. Once the KeyGroups have been defined using EHX,
all the keys within a KeyGroup can be changed with a single assignment in Production
Maestro (Pro mode only).
Label
A label is an alphanumeric name of up to five characters that identifies a source,
destination, or control function accessed by an intercom panel. Labels appear in the
displays of the intercom panel. Labels can identify panels, ports interfaced to other
external equipment, fixed groups, party lines, and special control functions.
Multiplexing
The process by which two or more signals are transmitted over a single
communications channel. Examples include time division and wavelength division
multiplexing.
Non-volatile Memory
Data stored in the CPU’s firmware (ROM) that is not lost when the power is turned off.
Palette
The port, keyGroup and Monitor selection screen in Production Maestro.
Panel
Also referred to as station in some cases (usually older manuals). Any intelligent
intercom device connected to the rear-panel analog ports of the central matrix. This
term does not refer to devices connected through interface modules.
Partyline
A wired shared communication system based on a single screened pair of wires.
Port
Any of the input/output connections (RJ-45 connectors) on the back panel of the central
matrix. These connectors and the attached cables connect the central matrix to remote
intercom devices. The term port emphasizes that the connection is a portal between the
central matrix and the remote intercom devices.
Program
Any separate audio source that is fed into the intercom channels. In television
applications, for example, program audio is the audio that is broadcast on air.
Project.
A project (stored and exported as an *.hxn file) provides a container for your
configurations, and may comprise one or many configurations for one or many
matrices.
A project can be used to define every aspect of a complex intercom system, including
the connectivity between multiple, intelligently linked matrices and/or the configurations
for individual matrices.
Rack Unit or RU
Standardized unit of mounting space on a rack panel. Each rack unit is 1.75 inches
(44.45 mm) of vertical mounting space. Therefore 1 RU is 1.75 inches (44.45 mm) of
vertical mounting space, 2 RU is 3.5 inches (88.9 mm), 3 RU is 5.25 inches (133.35
mm), and so on.
Remote Panel
Any intelligent intercom device connected to the back-panel ports of the central matrix.
This term does not refer to devices connected through interfaces.
