7.4.2.2 Reinserting the Card
If the same card is inserted again into the NL115, the datalogger will store all
data to the card that has been generated since the card was removed that is still
in the CPU memory. If the data tables have been left on the card, new data will
be appended to the end of the old files. If the data tables have been deleted,
new ones will be generated.
Check the status of the card before leaving the datalogger.
If a CF card was not properly accepted, the NL115 will flash
orange. In that case, the user needs to reformat and erase
all data contained on the CF card. Formatting or erasing a
CF card might be done on a PC or datalogger. The
procedure for formatting a CF card is explained in Appendix
A, CF Card Maintenance.
7.4.2.3 Card Swapping
When transporting a CF card to a computer to retrieve data, most users will
want to use a second card to ensure that no data is lost. For this method of
collection, use the following steps.
1. Insert formatted card (“CF-A”) in NL115 attached to datalogger.
2. Send Program containing
CardOut() instruction(s).
3. When ready to retrieve data, press the NL115 Initiate Removal button to
remove the card. The LED will be red while the most-current data is
stored to the card and then turn green. Eject the card while the LED is
green.
4. Put in the clean card (“CF-B”).
5. Use CardConvert to copy data from CF-A to PC and convert. The default
CardConvert filename will be TOA5_stationname_tablename.dat. Once
the data is copied, use Windows Explorer to delete all data files from the
card.
Windows98 and WindowsME users need to shift-delete to
completely delete files. Using standard delete may create an
invisible recycle bin on the CF card.
6. At the next card swap, eject CF-B and insert the clean CF-A.
7. Running CardConvert on CF-B will result in separate data files containing
records since CF-A was ejected. CardConvert can increment the filename
to TOA5_stationname_tablename_0.dat.
8. The data files can be joined using a software utility such as WordPad or
Excel.
CardConvert File CF-A Record Numbers CF-B Record Numbers
TOA5_tablename.dat 0-100
TOA5_tablename.dat 101-1234
TOA5_tablename.dat 1235-….
