To use more than one probe per datalogger, either connect the different probes
to different terminals on the datalogger or change the SDI-12 addresses of the
probes and wire them to the same terminal. Using the SDI-12 address reduces
the use of ports on the datalogger and allows probes to be connected in a
“daisy-chain” fashion which can minimize cable runs in some applications.
(See below for limits on the total cable length.)
The SDI-12 address of the CS215 can be set two ways:
• By sending the required commands to the sensors via an SDI-12
recorder/datalogger that allows talk through to the sensor (see
Appendix D.2, SDI-12 Transparent Mode )
• By loading a program into the recorder that sends the required
commands
7.2 Datalogger 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 .
