Data files from TableFile() instruction (TOA5, TOB1, CSIXML
and CSIJSON)
o Keep memory (OS variables not initialized)
o Dynamic runtime memory allocation
Additional final data storage is available by using the optional CF
(p. 451)
card with
a CF module listed in the appendix Card Storage Module
,
or with a mass storage
device (see the appendix Mass Storage Devices ).
5.1.7 Data Retrieval
Data tables are transferred to PC files through a telecommunications link
(Telecommunications and Data Retrieval
(p. 354)
) or by transporting a CF card
(CRD: drive) or Campbell Scientific mass-storage media (USB: drive) to the PC.
5.1.7.1 Via Telecommunications
Data are usually transferred through a telecommunications link to an ASCII file
on the supporting computer using Campbell Scientific datalogger support
software (see Datalogger Support Software
(p. 76)
). See also the manual and Help
for the software being used.
5.1.7.2 Via Mass-Storage Device
Caution When removing a CS mass storage device (thumb drive) from the
CR3000, do so only when the LED is not lit or flashing. Removing a Campbell
Scientific mass storage device from the CR3000 while the device is active can
cause data corruption.
Data stored on Campbell Scientific mass storage devices are retrieved through a
telecommunication link to the CR3000 or by removing the device, connecting it to
a PC, and copying / moving files using Windows Explorer.
5.1.7.3 Via CF Card
Caution When installing a CF
(p. 451)
card module, first turn off the CR3000
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 CR3000 power off.
Removing a card or card module from the CR3000 while the CF card is active can
cause data corruption and can damage the card.
Sending a program to the CR3000 may erase all data. To prevent losing data,
always collect data before sending a program to the datalogger.
The CR3000 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. 456)
command. Before collecting
