CPU Card

Two CPU cards are fitted to each Eclipse HX-Delta (one for the Delta Lite), in a master and slave relationship. The second CPU card provides redundancy in the case of outages or planned maintenance.

The master CPU card:

• 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.

Notes:	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 EHX Configuration Software.
	The cards slide vertically into the front of the matrix and connect to the backplane.
