In the case of cables >50m you have to solder in a terminating resistor of approx. 330
Ω
on the receiver for data free traffic.
Pin 6 (P5V) of the isolated interfaces carries the isolated 5V supply with the
respective ground 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.
