2.8.5 MC-3010A/3020D jumper setting
This section shows how to set the MC-ANLG Board (24P0115, for MC-3010A) and
MC-DIN Board (24P0116, for MC-3020D).

Setting MODBUS addresses
Use the rotary switch U18 to set the MODBUS address with a digit of number from "0".
When multiple sensor adapters are connected to the MC-3000S, the same number
cannot be used among them. (The same number can be shared between the MC-
3000S and a sensor adapter.)
Setting termination resistors
Use the jumper block J25 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. If not, communication between sensor
adapters is not possible.
