Port Card
A port card controls the operation of panels and interfaces connected
to it. Panels and interfaces connect to the port card through RJ-45
connectors, or “ports,” on the matrix’s rear panel. Shielded category-5
cable attaches the panel or interface to the RJ-45 connector.
The MVX-A16 analog port card sends balanced audio and RS-422
data signals to connected audio equipment through 4-pair shielded
category-5 cable. The card connects up to 16 remote audio
devices—such as intercom panels, interfaces, or 4-wire audio
equipment—to the central matrix. Each audio device connected to a
port card communicates with all other audio devices in the system and
with the central matrix.
For intelligent linking, shielded category-5 cable is run from a port on
one Eclipse Median to a port on a second Eclipse Median to form a
trunkline connection.
Fiber Card
Fiber cards connect Eclipse matrices together to provide a high speed,
dual redundant link to transfer audio samples and data between
systems. These connections can be configured in various ways to
provide protection against the loss of a link or a node.
Each fiber card link consists of a front card with various status
indicators and a rear card with two Duplex LC Terminated fiber optic
connectors (TXVRA and TXVRB).
E-Que Card
The E-QUE card allows the Eclipse matrix connectivity to
FreeSpeak/CellCom antennas and FreeSpeak/CellCom antenna
splitters. Each E-Que card set consists of a front card with a reset
button and various status indicators, and a rear card with eleven RJ45
ports giving eight standard ports, DECT sync in and out and a LAN port
for diagnostic use.
Each E-Que front card has status LEDs for power, port activity and
LAN status. The port activity LEDs indicate whether there is a device
connected to an E1 port and that a connection has been established
between this port and the connected device.
The E-Que cards must be fitted in the rightmost available slots
(furthest away from the CPU cards) on the Median and up to four
E-Que cards can be fitted on a matrix.
Interface Modules
An interface module converts the 4-wire signals transmitted from the
matrix to other types of signals that communicate with such external
devices as telephones, camera intercoms, two-way radios, and so on.
In this way, non-4-wire devices can communicate with the matrix.
