1) The 0V terminal must always be wired.
The MPI (Profibus DP) is not isolated.
The max. baud rate is 1.5 Mbit/s.
The terminating resistors should be provided externally in the plug connector, in
accordance with the Profibus standard. Alternatively the termination in the plug
connector can be implemented using jumpers between LINE A and TERM A, as
well as LINE B and TERM B.
The 5V must not be used as a power supply for systems of other suppliers. It is
neither overload nor short-circuit proof.
