WS product family: Communication after protocol change

How to communicate with a WS-Sensor and the UMB-config-Tool if the protocol was changed for example to Modbus or SDI-12?

After a Reset ( switching On/Off the sensor) every WS-Senor will start up for the first 5 seconds in UMB-protocol and the standard baud rate of 19200Bd. Independend to the configured protocol and baudrate settings of the WS-Sensor.

In this first 5 Seconds you will be able to connect via UMB-config-Tool to the WS-Sensor after this first command was send the UMB-protocol will stay for 10 minutes after that it switches back to the original configured protocol. This Time will always be extended to 10 minutes if a new UMB command was send.

WS product family: SDI-12 wiring plan for Device version >= 42

How to connect a WS-sensor with a device version >= 42 (hardware version >=14) to a SDI-12 system?

The wiring plan has changed compared to the wiring plan of older WS-Sensor device versions.
The new wiring plan is:

  • +VDD = brown
  • GND = white
  • SDI12_Signal = yellow
  • SDI12_GND = white

This is also mentioned as a note in the latest WS-sensor manual in the section 8 Connections
