Using External Memory Card

The external memory card is used to store log files that have been

copied or moved from the internal log directory. The data can be

retrieved from the external memory card via terminal connection or by

switching the memory card with an empty one.

The external memory card can be removed from the QML logger for

data retrieval without interruptions to operations. The logger copies

data from the internal log directory to the memory card daily at

midnight, the default time is 00:00:30. Data is being written when the

LED on the logger cover to the left of the external memory card is

constantly on.

When a new memory card is inserted into the QML logger, the software

checks that the card is ready for use. The status of the memory card is

indicated by a LED. Table 21 on page 102 describes the different

blinking sequences and the card conditions they indicate.

NOTE

If the CompactFlash memory card has not been formatted, it must be

formatted before use.

In MAWS versions 6.00 and later, you are recommended to format the

card in a Windows PC. The file system to use is FAT (not FAT32).

Also, do not select the quick format option.

To format the CF card in the QML logger, insert it into the CF slot of

the QML logger. Give the EXTFS ERASE command. After the card

has been formatted, you can remove it from the slot.

CAUTION

The memory card must not be removed from the QML logger while

data is being written, or the data may be lost. By default, data is

transmitted to the memory card each day at 00:00:30.
