D-sub socket (X003)

Pin 6 transfers 5 VDC, pin 5 transfers GND for the active termination resistor. These must never be used for other functions, as this can lead to destruction of the device. Pins 3 and 8 transfer the PROFIBUS signals. These must never be swapped over, as this will prevent communication.
