    "All registers are holding registers (FC03 read, FC06/FC10 write). Addresses here are the zero-based hex addresses of the manual; the manual's decimal register numbers are one higher (e.g. 0x03E7 = register 1000).",
    "32-bit values and floats span two registers with the high-order half first.",
    "Factory settings in normal mode are 57600 baud, address 1, Modbus RTU. For the first 5 seconds after power-up the RS-485 port also answers at 9600 baud, address 1, and stays in that mode while it is used.",
    "Energy registers are integers whose scale, digit count and decimal places follow the power and energy format setting. Reset the energy after changing that format.",
    "The 3-phase power readings at 0x0383-0x0388 are updated every 6 cycles; the other readings every 60 cycles.",
    "Not in this map: the programmable settings, the meter programming and encryption blocks and the secondary readings."
