How to use the Modbus configuration software
- Unzip file and run file application "Daviteq Modbus Configuration Tool Version"
- Choose COM Port (the Port which is USB cable plugged in)
- Set the BaudRate: 9600, Parity: none
- Click “ Connect “ untill the Status displays “disconnected” to “connected“. It means the modbus sensor is being connected with computer;
- Next, we need to import the configuration file. Go to MENU: FILE / Import New / => select the template file.
Step 3: Configure parameters of the sensor.
