Modbus Slave Address Configuration: The operator may assign a unique Modbus address to each controller (slave) unit that may be in the system. This allows the master controller to differentiate between the modules. For example, to name the controller address 21, place the shunts on LK1, LK4, and LK16 (1 + 4 +16 = 21). Typically, this configuration is set to (1) by the factory.
