3.8.1 General
The data module serves for the storage of configuration data and data occurring in the operation of
AFMS3000 on an SD memory card. For this purpose, the module contains its own microcontroller,
which makes reading and writing of the SD memory card independent of the higher-level system.
Integration into the system takes place via a special interface.
3.8.2 Power supply
The module receives its 5V power for supplying the microcontroller via the interface. From this
voltage, 3.3V is generated internally for supplying the SD memory card.
3.8.3 Connector
Communication takes place via an RS232 driver module. The data module is also supplied with 5V
operating voltage via the connector.
3.8.4 LEDs
Three status LEDs are provided on the back of the module:
Green LED: Module ok, access to SD card file system possible
Yellow LED: File open for reading or writing
Red LED: Read or write operation, fault on steady light indication
3.8.5 SD memory card slot
A slot is provided at the rear of the module for receiving an SD memory card. This locks in place after
it is pushed into the slot. The memory card can be removed by exerting light pressure on the same.
