The number of different types of interface card you can fit to the matrix frame is
limited by the available port count (112 audio ports). For more information, see
4.4.3 Combining interface cards in the frame.
Interface cards slide vertically into the front of the matrix frame and connect to
the backplane.
Note: The term central matrix is used to differentiate the core hardware and software
from the connected intercom panels and interfaces. The central matrix itself
consists of the matrix hardware (in this case, the Eclipse HX-Median) and the
EHX configuration software.
Note: For detailed information about installing interface cards, see 4.4 Installing
interface cards.
3.3.1 MVX-A16 analog port card
An MVX-A16 analog port card controls the operation of panels and interfaces
connected to it. Panels and interfaces connect to the port card through an RJ-45
connector (port) on the HX-Median 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 CAT5 cable. The card
connects up to 16 audio devices (such as user panels, interfaces, or four-wire
audio equipment) to the central matrix.
Each audio device connected to an analog port card communicates with all other
audio devices in the system and with the central matrix.
3.3.1.1 Intelligent linking
For intelligent linking, shielded CAT5 cable is run from a port on one Eclipse HX-
Median matrix to a port on a second Eclipse HX-Median matrix to form a
trunkline connection.
3.3.2 E-FIB fiber card
E-FIB fiber interfaces connect Eclipse HX matrices together to provide a high
speed, dual redundant link to transfer audio samples and data between systems.
These connections can be configured to provide protection against the loss of a
link or a node. E-FIB cards should be installed in the last port slot.
Each E-FIB fiber interface card set comprises:
A front card with various status indicators.
A rear card with two Duplex LC Terminated fiber optic connectors
(TXVRA and TXVRB).
