Sensor termination
If you are using multiple CAN combination sensors for smoke, temperature, and humidity, you must set the TR (transmission switch) to "OFF" for all sensors except the last one.
Image a) The last sensor in the CAN bus connection chain should have a termination switch in the "ON" position.
Image b) All other sensors should have a termination switch in the "OFF" position.
Konfiguration
In this example, we connect two CAN combination sensors for smoke, temperature, and humidity in series.
After connecting, the red configuration LEDs on the back of the sensors will light up.
After connecting the sensor to the CAN bus chain, go to the Didactum web interface >> menu item "CAN Configuration" >> click on "Configure" >> "Do you want to start the CAN configuration?" and confirm with "Yes". The following should then be displayed.
Once the sensors are configured, they will appear in the window. The blue configuration LED on the back of the sensors should light up.
You should see both sensors in the CAN configuration window.
