RS232 to SDI-12 Interface
The TBS06 (DR) RS232 to SDI-12 Converter is an interface for connecting a PC, data logger or
RTU to one or more sensors with SDI-12 interface. The TBS06 connects to the RS232 interface
and provides a SDI-12 compliant data interface. The TBS06 is a versatile tool for everyone who
designs sensors and data recorders or who installs, tests or maintains SDI-12 based data
acquisition systems.
It is available in a IP67 housing from Fibox or in a Dinrail housing.

    V1.1 TBS06 RS232 to SDI-12 Interface SDI-12 Basics SDI-12 is a serial data communication standard for interfacing multiple sensors with a data recorder SDI-12 uses a shared bus with 3 wires: power (12V), data, ground Data rate: 1200 baud Each sensor at the bus gets a unique address which is in the range ASCII [0-9, a-z, A-Z]. The default address of every sensor is ASCII[0].
