Note: The config tool only supports Windows OS, IOS is not supported yet.

To configure the device access and connectivity, follow the steps provided below.

1. Connect TD210 to your laptop or computer through RS232, then open the Bivocom configuration tool, Click DTU Config on the left side, and click to Open Port to open the serial port, and choose your COM port of laptop or computer.

2. Click Reload, a window will be open tell you to restart the device, unplug the power adapter and power on TD 210 again then wait for entering into configuration status. It should show as loading DTU parameters successfully.

3. You can go to next step to configure the modem, including Basic Setting, Network Setting, MODBUS setting and Mqtt setting.

4. In Network settings, set Network work mode as FTCP because we are going to use MQTT, Datacenter number as 1 and Main Centre DNS Server as 8.8.8.8 . Refer below.

5. Now in MODBUS settings configure your MODBUS and RS485 sensor. Set MODBUS work mode as MODBUS disable and MODBUS Device address as 1. In ADC set all the parameters as default, please refer to the below image. In the sensors, section enter all the details related to your RS485 sensor which you will find in your sensor data sheet provided by the sensor manufacturer. For reference, I have used the RS485 XY-MD02 temperature & humidity sensor.

Note: The communication baud rate of the Basic setting and baud rate of the MODBUS setting should be the same.

6. Final step towards completing the MQTT configuration. Enter MQTT credentials in Bivocom Mqtt setting from your Fogwing Account's edge configuration page: Fogwing - > Edge Network -> IoThub Access -> MQTT.

7. You can set the data interval time by configuring Topic up time(sec). Please refer to Fig.6. After configuring all the parameters click the Save button to save the settings.

Note: Fogwing accepts data only in JSON format so please select the data format as JSON and currently Bivocom device does not support secure connection, so use 1883 unsecured port.

Once after completion of the above steps provided everything goes in line with the above-mentioned instructions, you will be able to see the data sent over to the Fogwing platform.

Now you are ready to analyze your RS485 sensor data at Fogwing IIoT Platform portal, you can check all the data within the data storage in the portal.

Hope you are able to complete the above steps are per the instructions provided. If you have any challenges or issues, you can reach out to the Bivocom team or the Fogwing team with your questions.

All Bivocom devices are tested and certified to connect with the Fogwing IIoT Platform. If the TD210 does not address your requirements, you can try with other Bivocom devices.
