Measurements are read with function code 4 and the settings with function codes 3 and 16.", "The manual does not state the byte or word order; floats are read big-endian.", "Most settings are 32-bit floats holding a whole number. Parity and stop bits and baud rate need a restart to take effect.", "The display says the parity default is none, while the parity register says the default is 1 (even). The map follows the display.", "Meter is delivered with ID 1 and 2400 baud; the display allows 1200 to 9600 baud."],
