Rotary switch: Use the rotary switch (S2) to set the Modbus address when setting
connectors J4/J5 to Modbus. The Modbus address set at J4/J5 in the network is not
used. When setting J4/J5 to IEC61162-1/2, use the default setting (“0”).

Jumper block:
Use the jumper block J19 to set the termination resistor on/off for the MODBUS com-
munication on the connector J1. For the first and last sensor adapter in a series, their
termination resistors should be set to ON. Use the MC-CS Board with the default set-
ting because it becomes the “first” adapter in a series.
