TBS06-TS
RS232 to SDI-12 converter and bus sniffer
The TBS06-TS (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-TS connects to the RS232
interface and provides a SDI-12 compliant data interface. The TBS06-TS is a versatile tool for
everyone who designs sensors and data recorders or who installs, tests or maintains SDI-12 based
data acquisition systems. Furthermore it includes a SDI-12 bus sniffer mode.
It is available in a IP67 housing from Fibox or in a Dinrail housing.

TBS06-TS
RS232 to SDI-12 Interface
1 Introduction
SDI-12 is a standard for interfacing data recorders with microprocessor-based sensors. SDI-12 stands for
serial/digital interface at 1200 baud. It can connect multiple sensors with a single data recorder on one cable.
It supports up to 60 meter cable between a sensor and a data logger.
The SDI-12 standard is prepared by
SDI-12 Support Group
(Technical Committee)
165 East 500 South
River Heights, Utah
435-752-4200
435-752-1691 (FAX)
http://www.sdi-12.org
The latest standard is version V1.3 and dates from July 18th, 2005. The standard is available on the web site
of the SDI-12 Support Group.
TBS06-TS implements all functions for interfacing SDI-12 sensors to a RTU, data logger or PC with RS232
interface.
It is a plug and play solution for controlling or testing of sensors with SDI-12 interface.

3 Functional Description
3.1 Overview
The SDI-12 standard defines a set of commands to configure sensors and to initiate measurements. Upon
receiving specific commands, the sensor may carry out internal tasks, respond with information on
conversion time or send measurement data.
SDI-12 commands typically are ASCII strings generated by the data recorder/controller firmware. TBS06-TS
can be controlled by a PC application or hyper terminal and converts the command strings to the logic levels
and baud rate specified by the SDI-12 standard. Furthermore TBS06-TShandles breaks, marks and all other
details of the SDI-12 protocol.
Upon receiving data or status information originated by a Sensor, TBS06-TS extracts the corresponding
ASCII strings and sends it to COM Port of the PC.

Figure 2 – TBS06-TS basic application setup
The application is built based on a SDI-12 Recorder Protocol Stack Module. It receives commands from the
RS232 Interface (e.g. via data logger, RTU or PC), and transfers the commands to the SDI Interface, waits
for sensor response and transfers the response (measurement results, etc.) back to the RS232 Interface of
the data logger, RTU or PC. All SDI-12 commands are supported.

3.3 SDI-12 Monitor mode
In SDI-12 monitor mode, TBS06-TS monitors the data traffic between recorder and sensor(s). This feature is
useful in setting up or debugging SDI-12 installations. More details are available here.
