Protocol can be set to MODBUS RTU, and Address can be set to any value in the range of 1 to 247. When multiple SUN2000s communicate with the SmartLogger over RS485, the RS485 addresses for all the SUN2000s on each RS485 route must be within the address range set on the SmartLogger and cannot be duplicate. Otherwise, the communication will fail.
