Notes:
- Do not use other settings than the ones mentioned in the table.
- It is recommended to assign increasing addresses starting from the main master
at the left and moving right.
- Assigning the same address to different filter units in one filter system will lead
to the filter not being able to start up and go in error (Bad Ratings).
When a filter consists of more than one unit, attention has to be paid to the proper
termination of the communication bus between the different units. This communication
bus is depicted in
From previous unit (if present)

In order to terminate the bus correctly, the fourth switch (counting from bottom to top)
