3.3 Interface cards
You can fit 4 interface cards to the Eclipse HX-Delta.
The number of different types of interface card you can fit to the matrix is limited by the available port
count (496 audio ports). For more information, see 4.4.3 Combining interface cards in the matrix.
Interface cards slide vertically into the front of the matrix 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-Delta) and the EHX configuration software.
Tip: For detailed information about installing interface cards, see 4.4 Installing interface cards.
3.3.1 MVX-A16 analog interface card
An MVX-A16 analog port card controls the operation of panels and interfaces connected to
it. User panels and interfaces connect to the port card through an RJ-45 connector (port) on
the rear panel. Shielded CAT5 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.
Intelligent linking
For intelligent linking, shielded CAT5 cable is run from a port on one Eclipse HX-Delta matrix
to a port on a second Eclipse HX-Delta matrix to form a trunkline connection.
3.3.2 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 to provide protection against the loss of a link or a node.
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).
