When operating the device in SDI-12 mode it is basically no more possible to access the
device with the UMB Config Tool, due to the different interface parameter settings. To enable
configuration access nevertheless the interface is operated in standard UMB mode (19200
8N1) for the first 5 seconds after reset / power on. If a valid UMB telegram is received within
this time, the device will stay in UMB mode for the configured time out (several minutes) so
that the configuration can be modified.
Connect the PC to the WSxxx-UMB through an RS-485 converter
Start the UMB Config Tool and create a WSxxx-UMB with the address of the actual
device and activate at least one sensor. Start the measurement (will report
connection error at first)
Reset the device (Power off / on)
When measurement values are received the measurement can be terminated, the
interface is now open for configuration.
