Eclipse Glossary 1 0 - 3
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.
Party Line A wired shared communication system based on a single
screened pair of wires. See the Encore range. Matrix requires the
CCI-22 to interface to it.
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.
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.
Sidetone The sound of the panel operator’s own voice heard in their
own earphone as they speak.
Source In this manual, the term “source” refers to a device—such as
an intercom panel, interface, or beltpack —that sends audio into the
matrix. The device to which audio is sent is called a “destination”.
VOX In the Eclipse system, when audio at a panel exceeds a
threshold, a light switches on at the panel’s port card to visually cue
the operator. The threshold level is set in the Eclipse Configuration
Software.
V-Series Communications panels used with Eclipse systems providing
advanced facilities. Available in rack mount and desktop formats.
