2.4 COMMUNICATION
The TEROS 06 sensor communicates using different methods:
• DDI serial communications protocol
• SDI-12 communications protocol
• RS-485 tensioLINK communications protocol (M12 plug only)
• RS-485 Modbus RTU communications protocol (M12 plug only)
To obtain detailed instructions for using these protocols, read the
TEROS 06 Integrator Guide
.
The SDI-12 protocol requires that all sensors have a unique address. If the TEROS 06 is being
used with a non-METER logger using SDI-12 protocol on a bus, use the METER ZSC and the
METER ZENTRA Utility Mobile app to change the sensor SDI-12 address. See the individual
sensor integrator guide for more information about the SDI-12 protocol in the sensors.
NOTE: The sensor SDI-12 address must be returned to 0 to work with ZENTRA loggers.
1. Using a mobile device, open the ZENTRA Utility Mobile app.
2. Connect the sensor to the ZSC.
3. Under Sensor Information, select the SDI Address dropdown.
4. Scroll through the options and select the desired SDI-12 address.
NOTE: Address options include 0-9, A-Z, and a-z.
Detailed information can also be found in the application note
on METER digital sensors using Campbell Scientific data loggers and LoggerNet
(metergroup.com/address-csi-loggers).
When using the sensor as part of an SDI-12 bus, excite the sensors continuously to avoid
issues with initial sensor startup interfering with the SDI-12 communications.
