7.6.4 Sending CRBasic Programs
The CR3000 requires that a CRBasic program file be sent to its memory to direct
measurement, processing, and data storage operations. The program file can
have the extension cr3 or .dld and can be compressed using the GZip algorithm
before sending it to the CR3000. Upon receipt of the file, the CR3000
automatically decompresses the file and uses it just as any other program file. See
Program and OS Compression Q and A
(p. 433)
for more information..
Options for sending a program include the following:
•
Program Send
(p. 550)
command in datalogger-support software
(p. 90)
•
Program send command in Device Configuration Utility (DevConfig
(p.
113))
•
Campbell Scientific mass storage device
(p. 613)
or memory card
A good practice is to always retrieve data from the CR3000 before sending a
program; otherwise, data may be lost.
Note See File Management
(p. 456)
and the Campbell Scientific mass
storage device or memory card documentation available at

7.6.4.1 Preserving Data at Program Send
You can send CRBasic programs to the CR3000 in multiple ways. Depending on
the way you choose, the CR3000 keeps or deletes data already stored in memory.
Regardless of the program-upload tool used, if any change occurs to the following
data table structures, data are erased when a new program is sent:
•
Data table name(s)
•
Data-output interval or offset
•
Number of fields per record
•
Number of bytes per field
•
Field type, size, name, or position
•
Number of records in table
