CFM100 CompactFlash ® Module
Check the status of the card before leaving the datalogger. If a
CF card was not properly accepted, the CFM100 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 Section OV5 of the CR1000
and CR3000 manuals. NOTE
7.3.2.3 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 CFM100 attached to datalogger.
2. Send program containing CardOut() instruction(s).
3. When ready to retrieve data, press CFM100 button to remove card. LED
will show red while the most current data is stored to the card and then go
green. Eject card, while LED is green.
4. Put in 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. NOTE: 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.
