3.5.2 Nine Pole D-Sub
Pin 6 is 5 VDC und Pin 5 is GND for the active termination resistor. These must never be
misused for other functions, as this can lead to destruction of the device. Pin 3 and pin 8 are
the Profibus signals. These must never be swapped over, as this will prevent communication.
Shield is connected to the D-Sub housing that is coupled with low-resistance to the mounting
rail.
