How to change the SDI-12 address of your METER digital sensor

Managing your sensor SDI-12 address using the ZENTRA Utility app on a laptop

1. Go to Actions and launch the digital sensor terminal.

2. Select the appropriate port for the sensor that you would like to talk to from the sensor port drop down menu. If your port is not available, exit to the main screen and configure the sensor port to the correct sensor. Please note that ZENTRA Utility cannot auto-configure its ports if the sensor address is non-zero. You will need to configure it manually. Refer to the manual for configuration instructions. Only digital sensors are available in the drop down.

3. Select the “Identify Sensor Address…” command from the Digital Sensor Commands drop down menu. ?I! Will appear in the command line as shown in Fig 1.

4. Press Send.

5. The sensor will return the information for that sensor. The address is the first character returned. The screenshot below has a sensor address of 2.

6. The aAb! command is used to change sensor addressed “a” to address “b”. Enter 2A0! Into the command line and press Send to change a sensor addressed 2 to address 0 as shown below in Fig 2.
