Technical Description ________________________________________________________________
External Compact Flash Card
The MAWS system can also log data and reports on a Compact Flash
memory card, expanding the memory capacity to hundreds of
megabytes.
The external memory card is used for storing data files which have
been copied/moved from the internal log directory. The internal log
system, file format and operation is not changed, and is operated
parallel to the external card. The copy/move is carried out once a day,
typically just after midnight. In case the internal memory becomes full
earlier, the oldest files are moved to the external log module.
QML201 Logger with a Compact Flash Memory Card
The external log memory card can be hot-swapped with a new card
without any command or stopping the logging operation.
The data can be retrieved from the memory card via a terminal
connection using Zmodem protocol or by swapping the memory card
with empty one. Due to the large amount of data on the card, the
contents of the card are most conveniently read directly to a PC.
However, it is also possible to retrieve data records or complete files
remotely from the CF card.
