It is necessary to use a pair twist cable: the RS-485 data (lines A and B) must form a twisted pair. If the same cable is used to power the devices, it is necessary to pay attention to the cross section of the conductors: a voltage drop on a long line can lead to the fact that the devices will not work. Finally, you should choose a shielded cable. | It is necessary to use a pair twist cable: the RS-485 data (lines A and B) must form a twisted pair.
