19.6 Communication in SDI-12 Mode
The communication in the SDI-12 mode of the Smart Weather Sensor is conforming to the
standard defined in ‚SDI-12 A Serial-Digital Interface Standard for Microprocessor-Based
Sensors Version 1.3 January 12, 2009‘ . The device may be operated in bus mode together
with other SDI-12 sensors, connected to one SDI master (logger).
19.6.1 Preconditions for SDI-12 Operation
As the interface settings defined in the SDI-12 standard are significantly different from the
UMB default settings the related parameters have to be set properly by the UMB Config Tool
(latest version!).
The protocol mode of the device has to be set to “SDI-12”. This will automatically set the
baud rate to 1200.
Measurement data can be transmitted alternatively in metric or US units. The selection is
done by the UMB Config Tool.

Note: Please observe drawings on next page and notes on page 26 when connecting a
