Description
SDI-12 to RS485 Converter TBS07 for connecting PC, data logger or SDI-12
The SDI-12 to RS485 Converter TBS07 from Tekbox is an interface box for connecting a PC, data logger or telemetry device to one or more sensors with an SDI-12 interface. The device connects to a data logger, telemetry device or other device with an RS485 interface and provides an SDI-12 compatible sensor interface. The TBS07 DR is a versatile tool for anyone who integrates sensors and data loggers, or who installs, tests or maintains SDI-12 based data acquisition systems. It is available in an IP67 or optionally as a Din Rail housing.
The SDI-12 standard defines a set of commands for configuring sensors and for initiating measurements. Upon receiving specific commands, the sensor can perform internal tasks, respond with information about the conversion time or send measurement data.
SDI-12 commands are typically ASCII strings generated by the firmware of the data recorder/controller. The TBS07 can be controlled by a PC application or hyper terminal. It converts the command strings to the logic levels and baud rates specified by the SDI-12 standard. In addition, the TBS07 handles pauses, marks and all other details of the SDI12 protocol.
After receiving data or status information originating from a sensor, the TBS07 extracts the corresponding ASCII strings and sends it to the COM port of the PC.
