3.4 Interface cards
3.4.1 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-Omega 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 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 CAT-5 cable is run from a port on one Eclipse HX-Omega
matrix to a port on a second Eclipse HX-Omega matrix to form a trunkline connection.
Tip: For the order in which all interface cards must be installed to the Eclipse HX-Omega,
see 4.4 Installing interface cards.
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 (the Eclipse HX-Omega matrix) and the EHX configuration software.
Cards slide vertically into the front of the matrix and connect to the backplane.
3.4.2 E-FIB fiber interface 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 in various ways to provide protection against the loss of a link or a node.
Each E-FIB fiber interface comprises:
• A front card with various status indicators.
• A rear card with two Duplex LC Terminated fiber optic connectors
(TXVRA and TXVRB).
E-FIB interfaces should normally be fitted to slots 14 and/or 15 of the HX-Omega matrix
(furthest away from the CPU cards).
Tip: For the order in which all interface cards must be installed to the Eclipse HX-Omega,
see 4.4 Installing interface cards.
Note:
Cards slide vertically into the front of the matrix and connect to the backplane.
