For isolated interfaces you have 5V (P5V) isolated at pin 6 and the corresponding ground
(M5V) at pin 5. With this isolated voltage, you can assign defined static voltage levels to
the signal lines and so ensure a low reflection level.

*) For line lengths >50m, you have to solder a terminating resistor of approx. 330W on
the receiver side for traffic-free data transfer.
