FTS SDI-RAINE-HYDRO, User Manual

Page: 17 / 27

To test the weighing scale one has to put a (known) weight into one pan of the collecting vessel and click “ Test
Scale ” (blue gear wheel icon) in the tab “ Scale ”.
To simulate precipitation amounts to check the output signals of the pulse and analogue outputs, one has to
select the desired amount from the drop-down menu in the tab “
Simulation ” and click “ Simulate Precipitation ”
(cloud icon). The analogue and pulse outputs will return signals according to the applied settings in the rain[e]
Setup.
9 SDI-12 Interface
The communication using SDI-12 protocol via SDI-12 interface is based on the ‘SDI-12 A Serial-Digital
Interface Standard for Microprocessor-Based Sensors, Version 1.3, 2012’. The
RAINE-HYDRO
can be used in
bus mode parallel to other
RAINE-HYDRO
s.
The following subset of SDI-12 commands were implemented into the
RAINE-HYDRO
.
For further details to the SDI-12 protocol we recommend the afore-mentioned standard document or the website
www.SDI-12.org.
