4.2.1  Biasing the Modbus RS-485 Device Network 

 

An  RS-485  network  with  more  than  one  device  needs  to  have  biasing  to  ensure  proper 
communication. The biasing only needs to be done on one device. 

 

The  ProtoNode  has  510  Ohm  resistors  that  can  be  used  to  set  the  biasing. 

The  ProtoNode’s 

default positions from the factory for the biasing jumpers are OFF. 

 

The OFF position is when the 2 RED biasing jumpers straddle the 4 pins closest to the outside of 
the board of the ProtoNode. (

Figure 11

). 

 

 

Only turn biasing ON:

 

o

 

IF the BMS cannot see more than one device connected to the ProtoNode 

 

o

 

AND  all  the  settings  (Modbus  COM  settings, wiring,  and  DIP  switches)  have  been 
checked

 

 

To turn biasing ON, move the 2 RED biasing jumpers to straddle the 4 pins closest to the inside 
of the board of the ProtoNode.
