CR200/CR200X Series Dataloggers - Campbell Scientific

Section 3. Overview
3.1.5.1 Firmware: OS and Settings
Read More! See CR200(X) Configuration (p. 59).
Firmware consists of the operating system (OS) and durable configuration
settings. OS and settings remain intact when power is cycled.
Note The CR200(X) is shipped factory ready with all settings and firmware
necessary to communicate with a PC via RS-232 and to accept and execute user
application programs. OS upgrades are occasionally made available at
www.campbellsci.com.
For more complex applications, some settings may need adjustment.
Adjustments are accomplished with DevConfig Software (DevConfig (p. 59)) or
through datalogger support software (see Support Software (p. 143)).
OS files are sent to the CR200(X) with DevConfig or through the program Send
button in datalogger support software. When the OS is sent via DevConfig, most
settings are cleared, whereas, when sent via datalogger support software, most
settings are retained.
3.1.5.2 User Programming
Read More! See Programming (p. 69) and CRBASIC Programming
Instructions (p. 93) and CRBASIC help for more programming assistance.
A CRBASIC program directs the CR200(X) how and when sensors are to be
measured, calculations made, and data stored. A program is created on a PC and
sent to the CR200(X). Two Campbell Scientific software applications, Short Cut
and CRBASIC Editor, create CR200(X) programs.
• Short Cut creates a datalogger program and wiring diagram in four easy
steps. It supports most sensors sold by Campbell Scientific and is
recommended for creating simple programs to measure sensors and store
data.
• Programs generated by Short Cut are easily imported into CRBASIC Editor
for additional editing. For complex applications, experienced programmers
often create essential measurement and data storage code with Short Cut,
then edit the code with CRBASIC Editor. Note that once a Short Cut
generated program has been edited with CRBASIC Editor, it can no longer
be modified with Short Cut.
3.1.6 Memory and Data Storage
Read More! See Memory and Data Storage (p. 129).
The CR200(X) has 2K SRAM for communication buffers, calculations, and
variables, and 60K Flash EEPROM for the operating system and user program.
The CR200 originally had a 128K Serial Flash EEPROM for data storage.
Campbell Scientific has increased the data storage memory from 128 kbytes to
30
