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
follow.
MC-CS Board (24P0114)
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.
