rain[e]observer Precipitation Measuring System
• Pull out the clamping plug for the upper heating section and put the housing in a safe place. When putting
the housing upper section aside, avoid placing it on the cutting edge of the receiver opening, in order not to
damage it.
13.2 Change the device’s internal wiring
The following internal wiring is recommended.
To change the wiring, open the housing.
13.3 Change the output protocol
The precipitation type is only available in the SDI-12 extended protocol or the Modbus protocol.
The SDI-12 protocol can also be output via the RS485. Some data loggers on the market, such
as the Ser[LOG], support this mode, which enables cable lengths of up to 1 km to be used for
data transfer. Standard SDI-12 uses a signal to ground and is therefore limited to 65...100 m cable
length. If disruptions in the communication occur, we recommend allowing communication via
the RS485 interface, as long as the data logger (data collector) supports this function.
