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

(p. A-1).

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-….
