RS485 module

For the bus cable RS485, the twisted and shielded line is to be used
The shield must be a harness shield (not a foil shield)
The shield is to be connected to PE properly on both sides.
The pin assignment of the RS485 cable is different from that of the RS232 cable;
if you use the wrong cable, no communication is possible
