    "All registers are holding registers read with FC03. Settings are written with FC06 (one register) or FC10 (floats).",
    "Floats are IEEE 754 in ABCD order (high word first).",
    "Defaults: address 1, 9600 baud, 8 data bits, even parity, 1 stop bit. Baud rate can be lowered to 4800, 2400 or 1200; parity can be none or odd.",
    "Power is given in kW, kvar and kVA, energy in kWh and kvarh.",
    "The register map is shared with the PRO380; the registers it marks as PRO380 only (per-phase L2/L3 and CT values) are left out."
