7.4  Connection of the Modbus RS485 communication 

7.4.1 Characteristics 

of the network cable 

Recommended characteristics for the cable: 

  Shielded twisted pairs, maximum length 1000 m.  

  resistance < 100 ohms/km  

  capacity between wires < 60 pF/m  

  capacity between wire and shield < 100 pF/m 

It is imperatively necessary to tighten the fixing clamp on the shield and not on insulator, in 
order to ensure continuity of the shield of the cable and its earthing. 

 

7.4.2 Adaptation 

resistances 

of the RS 485 connection 

In order to adapt the impedance of the RS 485 connection, two resistances of 120 ohms are 
necessary. With this intention, NP800 relays are fitted with a resistance of 120 ohms and a 
jumper provided for this purpose. To carry out this adaptation, according to the diagram 
below, connect the terminal «Rterm" to the terminal "- T/R» of the two end relays of the 
connection thanks to the jumper. The jumpers of the other relays of the connection will have 
to be removed
