Step 2: Connect the Sensor Bridge

Do the same process to the Sensor Bridge.

  1. Connect the power supply to the screw connector in the front
  2. Connect an ethernet cable from the front port to your router Again, you should see the green indicator LED lit as well as the ethernet port LEDs showing traffic.
  3. Connect the T9602 sensor in place

The sensor will only be read after you send a HTTP request to the sensor. Network connections Your final connections should resemble the following architecture
