Never connect the shield of the cable with GND_ISO, as this could
destroy the interface!
Pin 6 (P5V) of the isolated interfaces carries the isolated 5V supply with the respective
ground GND on pin 5 (M5V). You may use this isolated voltage to provide defined static
voltage levels on the signaling lines by means of resistors and ensure that reflections are
reduced to a minimum.
