The Core Message Set

The Core Message Set is a subset of the API messages. When the Excel platform is shipped, it is not running system software. However, the Core Message Set is shipped on the Excel platform, residing in the firmware on the Matrix Controller card. The Core Message Set downloads system software from the host and queries the Excel platform.

When a valid download finishes, the Excel platform stops running the Core Message Set and starts running the System Software in RAM on the Matrix Controller card.

The following messages make up the Core Message Set:

• Alarm

• Become Active

• Card Status Query

• Clear System Software

• Download Begin BRecord

• Download Begin SRecord

• Download BRecord
