Configuration
3.5.4
Address Scan
The address scan is now part of the SDI-12 Devices in the configuration section of iLink (see section
).
3.6
Using iLink’s Sensor Configuration Tool
To optimize the process of maintaining multiple iRIS installations with the same (or similar) sensor configuration, iLink
includes a graphical configuration tool. This allows the configuration of any of the sensors to be changed, sent to the iRIS
or saved to the disk. It also supports the retrieval of sensor settings from the iRIS and from disk. This means that setting
up new iRIS is made very simple as a common configuration file can be sent to each iRIS.

iRIS Sensor Configuration Example
3.6.1
iRIS Sensor Configuration Example
This example shows how to set up a simple iRIS sensor configuration to measure water level from an SDI-12 sensor and
also log internal battery voltage. This example is valid for all iRIS.
1. Connect to the iRIS using iLink.
2. Invoke the iRIS sensor configuration form by selecting Sensors node from ConfigurationàGeneral Menu.
3. Expand the sensors branch and click the +Add Sensor option.
4. Click on the newly created sensor labelled “Disabled”.
5. Set up the water level sensor. Enter the sensor name “Water Level”.
6. Now set the sensor source from the drop-down list. Select source SDI-12. Then choose the correct SDI-12 device and
the variable. In our example, the instrument is ‘Hydserv-AD375M-H-104’ and we require the first value (variable 1).
7. Enter the multiplier to scale the value. For SDI-12 instruments, the multiplier is typically 1 as the instrument itself
provides an actual value in engineering units.
8. Enter the offset if required and known at this point. Usually, this is set on site to calibrate the measurement to a
known reference of datum. In this case the offset can be set by using the LCD calibration screen. See section
.
