• Provides the serial data and Ethernet connection to the connected EHX
PC.
• Coordinates the data flow between the other interface cards and modules
in the system, allowing them to communicate with each other.
• Stores up to four complete configurations, enabling the selection and
activation of a configuration directly from the card.
• Includes an additional, embedded configuration, which may be activated
from the card for fast fault checking after the installation or upgrade of
the Eclipse HX system.
Note: A configuration determines the operating parameters of the Eclipse HX matrix
system, including port functions, talk-and-listen audio routes, controls and other
functions. Configurations are created and managed in EHX, for download to the
matrices. For more information about EHX, see 3.6 EHX configuration
software in this document.
Note: The cards slide vertically into the front of the matrix and connect to the
backplane.
3.4 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 in this document.
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.
Note: For detailed information about installing interface cards, see 4.4 Installing
interface cards.
3.4.1 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.
