Modbus RTU Serial Communications 

The WR-90 field units act as simple pass-throughs for Modbus communications. As such, multiple 
Modbus enabled devices may be transmitted wirelessly using a wireless field unit. 

Note: Modbus Master must be connected to Base Station. 

 

Figure 17. Field Unit Three- and Five-Wire RS-485 Modbus Connection 

 

Figure 18. Field Unit Multiple Device RS-485 Modbus Connection 

Notes: 

1.  Termination resistors are optional and values depend on the cable length and characteristic 

impedance. Consult the cable manufacturer for recommendations. 

2.  Use shielded cable, twisted-pairs plus ground. Connect ground shield only at one location.
