    "Defaults: address 1, 9600 baud, 8 data bits, no parity, 1 stop bit. Baud rates 300 to 19200.",
    "Floats are sent low word first (the table's FLOAT REVERSE WORD); a setting in the setup registers can change this.",
    "The table numbers measurements 3xxxx and settings 4xxxx and gives the PDU address in hex; this map reads them as input and holding registers at those addresses. The table also says to add 1 to the address for function 3 holding-register access, so check the addressing on the device.",
    "The integer (HEX) copies of the measurements are not included: the table does not give their scaling.",
    "Settings that take a decimal range (pulse duration, pulse weight) are listed without a scale because the table does not give one."
