Page 25 MRC-565 Packet Data Radio Operations and Maintenance
Data Memory (RAM): The Data memory is volatile Dynamic RAM (32M X 16). Date, time,
executable programs, command parameters and program dynamic data (messages, data, position,
etc) are all stored in RAM during normal operations.
During normal operation, the MRC-565 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.
The RAM contents will be lost under the following conditions:
1. The Boot command is issued.
2. Power is removed from the unit.
3. The watchdog timer initiates a restart.
The software will detect these events and will recopy the parameters and configuration values
from Parameter memory back into RAM when operation is resumed.
If the contents of Parameter memory become invalid, the unit will revert to the factory defaults
in Program memory.
