B. JUMPER SETTING
The appliance display handles most of the Modbus adapter configuration. There is one jumper on the Modbus adapter. When this
jumper is in place (factory default) it connects a termination resistor across the data lines of the RS-485 connection. Leave the jumper
in if the Modbus adapter is at the end of the RS-485 bus. Remove the jumper if the Modbus adapter is one of many connections and
not at the end of the bus. See Figures 2 and 3.
