Select Modbus address using the upper bank of DIP switches labeled “ADDRESS” as shown 
in Figure 14. Switch 1 corresponds to the low-order bit of the address and setting a switch ON 
selects a bit value of 1. For example, set switches 1 and 3 on to select address 5. See Appendix 
A for a complete list of Modbus address switch settings. The Modbus address is set using 
the bank of dip switches circled in red in the Figure 14. Every meter in the Modbus network 
must have a unique Modbus address. The address is not set at the factory—it must be set 
appropriately at installation. Zero (all switches off) is not a valid Modbus address. The address 
255 (all switches on) is generally reserved and not recommended. The table below shows how to 
set the switches for each address.

 5. 

 

Select Modbus baud rate using the switches 1 and 2 in the lower bank of DIP switches, labeled 
“BAUD” as shown in Figure 14. Switches 3 – 8 are reserved for future use and must be set to the 
OFF position. Baud rate options are shown in Table 6.

 6. 

 

To use the Modbus RTU communication module the jumpers shown in Figure 14 be set in the top 
position, which is the default setting from factory. The jumpers must be set as shown in Figure 14 
regardless of the communication protocol in use.

 7. 

 

RS485 Line (Twisted Pair) Termination Jumper; when installed as shown in Figure 14, this 
jumper enables the internal RC line termination circuit. The jumper must be installed only if 
the meter is the last device in the daisy chain and otherwise must be removed. In the example 
shown above, only the meter at the far right of the diagram needs a termination jumper because 
it is the last device in the daisy chain.
