2.6.5  RS485 Wiring  

Each RS485 port can communicate to multiple RS485 devices by daisy chaining devices 
over a single twisted pair with transmit and receive signals on the same two wires (half 
duplex).  The following guidelines should be followed to ensure reliable continuous 
communication: 
 

1. To minimize the effects of ambient electrical noise, shielded cabling is 

recommended. 

2.  The correct polarity must be observed throughout a single daisy chain. 
3.  The number of devices wired should not exceed 32, and total distance should be 

less than 4000 feet (at 100 kbps). 

4.  The Common terminals should be connected to the common wire inside the 

shield.  

5.  The shield should be connected to earth ground at a single point to avoid loop 

currents  

6.  The twisted pair should be terminated at each end of the chain. 

 
The figure below shows the recommended RS485 wiring. 
 

 

Figure 22: Conceptual recommended RS485 wiring diagram 

 

NOTES

:  

1.  On RS400 Series units with Phoenix ports, the Common (Isolated Ground) port is 

marked “Gnd”. See the Phoenix ports section for details. 

2.  On RS400 Series units with Phoenix ports, internal termination is provided. See 

the Phoenix ports section for details. 

3.  On RS400 Series units with RS232/RS485/RS422 DB9 or RJ-45 ports then no 

internal termination is provided. See the DB9 & RJ-45 port sections for details.
