datalogger support software to communicate with a CR300 over a USB
connection. For other configurations, see the EZSetup Wizard Help. Context-
specific help is given in each step of the wizard by clicking on the Help button
in the bottom right corner of the window. For complex datalogger networks,
use Network Planner .

A CRBasic program directs the CR300 how and when sensors are to be
measured, calculations made, and data stored. A program is created on a PC
and sent to the CR300. The CR300 can store a number of programs in memory,
but only one program is active at a given time. Two Campbell Scientific
software applications, Short Cut and CRBasic Editor, can be used to create
CR300 programs.
For most applications, Short Cut is a good place to start. Section 4.3, Create a
Program , works through a measurement example using Short Cut. When
(p. 9)
the application requires more complexity than Short Cut allows, enter as much
information as possible, and Short Cut creates a program from which to work,
already formatted with most of the proper structure, measurement routines, and
variables. The program can be edited further using CRBasic Editor. Appendix
A, Importing Short Cut Code Into CRBasic Editor
procedure.
Once a Short Cut generated program has been edited with
CRBasic Editor, it can no longer be modified with Short Cut.
CRBasic Editor is intended for use by programmers who need more
programming flexibility and control than can be provided through Short Cut.
This programming language is similar in syntax, program flow, and logic to the
Structured BASIC programming language. CRBasic has special instructions
for making measurements and for creating tables of output data. CRBasic
Editor is a component of LoggerNet and PC400 datalogger support software.
For more on CRBasic programming, refer to Appendix B, Introduction to
CRBasic Programming
(p. B-1)
See CRBasic Editor Help for detailed information on program structure,
syntax, and each instruction available to the CR300.

The CR300 requires that a CRBasic program file be sent to its memory to
direct measurement, processing, control, and data storage operations. The
program file may use the extension .CR300 or .dld.
Options for sending a program include the following:
• Short Cut
• PC200W | Send Program...
• PC400 | Send Program...
