Table 7-1 shows the SDI-12 wiring for the CS650 water content reflectometer.
SDI-12 data is transmitted to a CRBasic datalogger odd numbered control port or
U terminal. Wiring information for RS-232 communications is provided in
Section
8.1.1.2 , RS-232 Wiring
(p. 12)
.

The orange Rx wire is only used for RS-232 Tx/Rx communication,
and should be grounded when using SDI-12.
7.4 Programming
Short Cut is the best source for up-to-date datalogger programming code.
Programming code is needed,

when creating a program for a new datalogger installation

when adding sensors to an existing datalogger program
If your data acquisition requirements are simple, you can probably create and
maintain a datalogger 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.
Short Cut cannot edit programs after they are imported and edited in
CRBasic Editor .
A Short Cut tutorial is available in Section 4 , Quickstart
(p. 2)
. If you wish to
import Short Cut code into CRBasic Editor to create or add to a customized
program, follow the procedure in Appendix A , Importing Short Cut Code into a
Program Editor
(p. A-1)
. Programming basics for CRBasic dataloggers are
provided here. Complete program examples for select CRBasic dataloggers can
be found in Appendix
B , Example Programs
(p. B-1)
. Programming basics and
programming examples for Edlog dataloggers are provided at
www.campbellsci.com\old-manuals .
The SDI12Recorder() measurement instruction programs CRBasic dataloggers
(CR6, CR200(X)-series, CR800-series, CR1000, CR3000, and CR5000) to
measure the sensor. This instruction sends a request to the sensor to make a
measurement and then retrieves the measurement from the sensor. See Section
8.2 , SDI-12 Measurements
(p. 19)
, for more information.
When using a CR200(X), the SDI12Recorder() instruction has the following
syntax:
