The following are the main elements of the Eclipse central matrix:
Central Processing Unit (CPU)
The nucleus of the matrix communication system is the central
processing unit (CPU). It provides the serial data and Ethernet
connection to the connected PC computer. The CPU also coordinates
the data flow for other features of the system, such as general-purpose
outputs and inputs. The CPU stores four complete system
configurations in its memory, which can be retrieved and activated
directly from the matrix’s front-panel controls, even when the matrix is
not connected to a computer.
Each matrix system contains at least one central processing unit,
located either on its own removable circuit card, or in internal circuitry.
Some matrices, such as the Eclipse Omega, contain a backup CPU for
fail-safe operation.
Internal Circuitry
The matrix’s internal circuitry controls the operation of the panels and
interfaces connected to it. Panels and interfaces connect to the
matrix’s internal circuitry through an RJ-45 connector, or “port”, on the
matrix’s rear panel. The internal circuitry sends balanced duplex audio
and RS-422 data signals to and from connected audio equipment
through 4-pair shielded category-5 (CAT-5) cable (STP).
Each audio device connected to the matrix can communicate with all
other audio devices in the system. For intelligent linking, shielded
category-5 cable is run from a port on one Eclipse matrix to a port on a
second Eclipse matrix to form a trunkline connection.
The Eclipse Omega and Median matrix internal circuitry can also
control fiber optic interfaces to provide high-speed links between
matrices and E1 interfaces to allow communication with wireless
system antennae.
Power Supplies
Each Eclipse Omega or Median matrix can hold two independent
power supplies. These may be connected to a main and backup
power source for redundancy. In the event of failure of one of these
power supplies, the second supply automatically takes over.
In the event of a complete power failure, a matrix can automatically
restore itself to complete functioning by retrieving configuration
information from its non-volatile operational memory.
The Eclipse Pico and Eclipse-32 matrices have a dual AC input power
supply unit.
