2.3.3 How to set jumper blocks in the sensor adapters
MC-3000S
Set the jumper blocks in the MC-CS Board (24P0114) referring to the tables that fol-
low.
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 IEC 61162-1/2, 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.

Set the jumper blocks J14 through J17 to turn the termination resistors on connectors
J4 through J7 respectively.
(Termination resistor ON)
• When setting the starting/ending terminal for the multipoint, or the multipoint is not
connected (CH1 to 4).
• When setting the starting/ending terminal for Modbus (CH1, CH2)
