Campbell Scientific CR1000 Measurement and Control System - Manual (Page 68)

Section 5. System Overview
68
Data stored on Campbell Scientific mass storage devices are retrieved through a
telecommunication link to the CR1000 or by removing the device, connecting it to
a PC, and copying / moving files using Windows Explorer.
5.1.8.3 Via CF Card
Caution When installing a CF
(p. 450)
card module, first turn off the CR1000
power.
Before removing a card module from the datalogger, disable the card by pressing
the "removal button" (NOT the eject button), wait for the green LED, and then
turn CR1000 power off.
Removing a card or card module from the CR1000 while the CF card is active can
cause data corruption and can damage the card.
Sending a program to the CR1000 may erase all data. To prevent losing data,
always collect data before sending a program to the datalogger.
The CR1000 manages data on a CF card as final storage table data. It accesses
the card as needed to fill data collection requests initiated with the Collect
command (see the Collect section
). If care is taken, binary data from the card can
be collected using the File Control Retrieve
(p. 454)
command. Before collecting
data this way, stop the CR1000 program to ensure data are not written to the card
while data are retrieved; otherwise, data corruption will result.
Data stored on CF cards are retrieved through a telecommunication link to the
CR1000 or by removing the card, carrying it to a computer, and retrieving the
data via a third-party CF adapter. Retrieving data, especially large files, is much
faster through a CF adapter than telecommunications with the CR1000.
The format of data files collected via a CF adapter is different than the standard
Campbell Scientific data file formats (see Data File Format Examples
(p. 336)
).
Data files read from the card via a CF adapter can be converted to a Campbell
Scientific format using CardConvert software (see CardConvert
(p. 449)
).
For more information on use of CF cards, see the CRD: Drive
(p. 334)
section.
5.1.8.4 Data File-Formats in CR1000 Memory
Routine CR1000 operations store data in binary data tables. However, when the
TableFile() instruction is used, data are also stored in one of several formats in
discrete text files in internal or external memory. See Data Storage
(p. 332)
for
more information on the use of the TableFile() instruction.
5.1.8.5 Data Format on Computer
CR1000 data stored on a PC via support software is formatted as either ASCII or
Binary depending on the file type selected in the support software. Consult the
software manual for details on available data-file formats.
