Data Logger Programming - Campbell CS240 Product Manual

(p. 11)). Using connectors between the sensor head and the station or data logger cable allows in-
field sensor head replacement without disconnecting the cable from the data logger.
The following table provides sensor wiring and cable pin-out. Detailed information about the
cables are provided in the
Configuration Utility and the MeteoPV User Interface.

7.2 Data logger programming

Short Cut is the best source for up-to-date data logger programming code. If your data
acquisition requirements are simple, you can probably create and maintain a data logger
program exclusively with Short Cut. If your data acquisition needs are more complex, the files that
Short Cut creates are a great source for programming code to start a new program or add to an
existing custom program.
NOTE:
Short Cut cannot edit programs after they are imported and edited in CRBasic Editor.
A Short Cut tutorial is available in
CRBasic Editor to create or add to a customized program, follow the procedure in
Short Cut code into CRBasic Editor
provided in the following section. Complete program examples for select CRBasic data loggers
can be found in Example programs
If applicable, please read
to programming your data logger.
