If the address of the indicator is set to 0, the weight information transmission starts with
any character received from the serial communication line. It should be noted that the
indicator address can be between 0 and 255.
If more than one SMART-2 indicators are connected to the same communication line,
RS485 type communication must be set and a different address must be assigned to
each device.
