Install new Firmware

Download the latest anb_utils and unzip

tip

Unzip the executable to it's own directory - do not run from the zip file

note

You cannot update firmware using RS485 due to its bidirectional data nature. Instead, you need to switch to RS232, which supports full duplex communication.

Power on your sensor and open anb_utils, the following will be displayed:

Select y if you want to install more firmware, or n if you have finished.
Once you have power cycled your sensor you can verify the firmware has installed successfully by restarting anb_utils and checking the splash screen.

tip

If using the ANB GUI, make sure you install the latest version to run with v9.5 firmware

note

Driver and Interface firmwares should be installed together. When you have installed one, the sensor details will not be available on the splash screen. Enter to continue and install the second. When both are successfully installed the sensor details will be available after power cycling.
