7.2.3 Table Size and Mode
The size of each data table in CPU memory is set as part of the DataTable()
instruction and the size of each data table on the CF card is set with the
CardOut() instruction. Because they are set independently, they can be
different. It is important to note that if the CPU memory is set to fill-and-stop
mode, once a table is full, all data storage to the table will stop. No more
records will be stored to the CPU memory or the card.
7.3 Data Retrieval
Data stored on CF cards can be retrieved through a communication link to the
datalogger or by removing the card and carrying it to a computer.
7.3.1 Via a Communication Link
Data can be transferred to a computer via a communications link using one of
Campbell Scientific’s software packages (for example, PC200W, PC400,
LoggerNet). There is no need to distinguish whether the data is to be collected
from the CPU memory or a CF card. The software package will look for data in
the CPU memory and then the CF card.
The datalogger manages data on a CF card as final-storage table data, accessing
the card as needed to fill data-collection requests initiated with the Collect
button in datalogger support software. If desired, binary data can be collected
using the File Control utility in datalogger support software. Before collecting
data this way, stop the datalogger program to ensure data are not written to the
CF card while data are retrieved. Otherwise, data corruption and confusion will
result.
7.3.2 Transporting CF Card to Computer
With large files, transferring the CF card to a computer may be faster than
collecting the data over a link.
