7.2 SDI-12 Wiring
Power down your system before wiring the SR50A. Never
operate the sensor with the shield wire disconnected. The
shield wire plays an important role in noise emissions and
susceptibility as well as transient protection.

To use more than one probe per datalogger, either connect the different sensors
to different terminals on the datalogger or change the SDI-12 addresses of the
sensors and wire them to the same terminal. Using the SDI-12 address reduces
the use of ports on the datalogger and allows sensors to be connected in a
daisy-chain that can minimize cable runs in some applications.
7.3 SDI-12 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
• Adding sensors to an existing datalogger program
