Switching on the bus termination
Bus termination is required to prevent signal reflections from the
bus cable ends. The adapter module is not equipped with internal
bus termination. Therefore, the D-SUB connectors at the first and
last modules of the bus must have built-on termination switched on
as shown in the diagram below.
The adapter module is able to supply power for an active-type
termination circuitry (30 mA max.).
