    "Measurements are float32 input registers (FC04); settings are float32 holding registers (FC03 read, FC16 write, one parameter per write).",
    "At most 40 values (80 registers) per request.",
    "Defaults: address 1, 9600 baud, no parity, 1 stop bit.",
    "Values a wiring type does not provide read 0.",
    "Corrected from the manual's table: export reactive energy is at 78 (0x4E; the table prints 0x4A) and the line-to-line voltages at 200-206 are in V (the table prints W).",
    "Names and descriptions are translated from the Polish manual."
