Connecting EAGLEHAWK NX via its RS485-1 Interface to a Modbus 

With regards to Fig. 49, please note the following: 

NOTE:

  Always power each EAGLEHAWK NX controller and the connected Modbus slaves via separate transformers. 

NOTE:

  For "L," see section "RS485 Standard" on pg. 10. 

NOTE:

  If any of the devices are electrically isolated, it is recommended that those devices be connected to signal ground. See 

section "RS485 Standard" on pg. 10.

Fig. 49. Connection of an EAGLEHAWK NX Modbus master controller via its RS485-1 interface to a Modbus with slaves 

 
The termination resistor must be inserted directly into the terminals of the last Modbus slave. 

NOTE:

  In this example, any or all of the Modbus RTU slaves depicted here can be EAGLEHAWK NX Modbus RTU slaves. In 

such cases, an EAGLEHAWK NX Modbus RTU slave positioned at the end of the Modbus (as "Modbus Module #N") 
must have its 3-position slide switches set to "End" (see Fig. 16) (the insertion of the aforementioned termination 
resistor is then unnecessary) and any EAGLEHAWK NX Modbus RTU slaves positioned elsewhere on the Modbus 
must have their 3-position slide switch set to "Mid" (see Fig. 14).
