Campbell Scientific CR800 and CR850 Measurement and Control Systems - Manual (Page 67)

Section 5. System Overview

o CRBasic variables
o Final Storage
o Communications memory
o USR: drive
User allocated
FAT32 RAM drive
Photographic images (See the appendix Cameras
(p. 540)
)
Data files from TableFile() instruction (TOA5, TOB1, CSIXML
and CSIJSON)
o Keep memory (OS variables not initialized)
o Dynamic runtime memory allocation
Note CR800s with serial numbers smaller than 3605 were usually supplied with
only 2 MB of SRAM.
Additional final data storage is optionally available by using a Campbell
Scientific mass storage device. See the appendix Mass Storage Devices
.
5.1.8 Data Retrieval
Data tables are transferred to PC files through a telecommunications link
(Telecommunications and Data Retrieval
(p. 332)
) or by transporting a Campbell
Scientific mass-storage media (USB: drive) to the PC.
5.1.8.1 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.
5.1.8.2 Via Mass-Storage Device
Caution When removing a CS mass storage device (thumb drive) from the
CR800, do so only when the LED is not lit or flashing. Removing a Campbell
Scientific mass storage device from the CR800 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 CR800 or by removing the device, connecting it to
a PC, and copying / moving files using Windows Explorer.
5.1.8.3 Data File-Formats in CR800 Memory
Routine CR800 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. 318)
for
more information on the use of the TableFile() instruction.
