3.7 Memory Organization

The MCC-545C has three types of memory:

3.7.1 Program Memory (PM)

The Program memory is non-volatile Flash (512K x 16). It contains the

MBNET200 image software, bootstrap, configuration, and application

software. These programs are installed at the MCC facilities at the time

of shipment. The information stored in the Program memory is referred

to as “factory defaults”.

3.7.2 Parameter Memory (CPM)

The Parameter memory is non-volatile Flash (512K x 16). It contains the

configuration data for the unit such as the customer number, the serial

number and ID of the MCC-545C, and the authorized FCC frequencies it

may use. This information is normally programmed into the unit prior to

shipment. The Script files are also stored in Parameter memory, either

at the MCC facilities or on site.

3.7.3 Data Memory (RAM)

The Data memory is volatile RAM (1024K x 8) and has battery backup.

Date, time, executable programs, command parameters, and program

dynamic data (messages, data, position, etc.) are all stored in RAM

during normal operations. As an option, the Data memory may be

expanded to 2048K x 8.

During normal operation, the MCC-545C software uses the data and

configuration parameters stored in RAM. If the data information in RAM

is lost or corrupted, for whatever reason, the configuration parameters

can be retrieved from Parameter memory. This ensures uninterrupted

operation.
