-    RS-422 / 485 is to transmit the signal by the power difference. 

Also, it is more safety rather other interface system for a electric 

noise. 

-    RS- 485 should be connected as follows. 

 

RXD(+) + TXD(+),  RXD(-) + TXD(-) 

-    Specially please use the cable with shield coax cable surely. 

-    Recommended distance is under 1.2 km. 

-    Both  end  side  of  a  wire  must  be  connected  by  the  termination  of 

300Ω.
