The TBS09DR is a converter to connect Modbus sensors to a SDI-12 master device such as a data logger or telemetry unit. It can connect multiple Modbus sensors in parallel by setting the corresponding address of the individual Modbus sensors using an extended SDI-12 command, upfront to issuing the measurement commands.
The TBS09DR provides a rich command set to offer maximum flexibility for configuring the device to a sensor with Modbus interface.
