the foldback. To do this, he uses a channel specifically
set up to interrupt the foldback audio.
Interface A piece of electronic hardware designed to convert the
4-wire signals of a central matrix port to some other form of
communication, such as 2-wire party line, telephone, etc. The interface
is connected to a central matrix port. The external non-4-wire device is
then connected to the interface.
ISO The ISO function, short for “station ISOlation,” allows you to call a
destination and interrupt all of that destination’s other audio paths and
establish a private conversation. When you complete your call, the
destination’s audio pathways are restored to their original state before
the interruption.
Label A label is an alphanumeric name of up to five characters that
identifies a source, destination, or control function accessed by your
intercom station. Labels appear in the displays of the intercom station.
Labels can identify stations, ports interfaced to other external
equipment, fixed groups, party lines, and special control functions.
Non-volatile memory Data stored in the CPU’s firmware (ROM) that
is not lost when the power is turned off.
Panel Another term for “station.” Any intelligent intercom device connected to
the rear-panel ports of the central matrix. This term does not refer to devices
connected through interfaces.
Port Any of the Eclipse matrix’s 208 input/output RJ-45 connectors
that are used to connect cable from the matrix to stations, panels, and
interfaces. Each “port” connects to a separate audio channel in the
matrix intercom system.
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.
Station Another term for “panel.” Any intelligent intercom device
connected to the rear-panel ports of the central matrix. This term does
not refer to devices connected through interfaces.
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.
Sidetone The sound of your own voice heard in your own earphone as
you speak.
Source In this manual, the term “source” refers to a device—such as
an intercom station, interface, or beltpack —that sends audio into the
matrix. The device to which audio is sent is called a “destination.”
