    "Register numbers are those of the reference manual (1-based, as POWERLOGIC devices are read: register 1000 is holding register 41000, sent as 999). The manuals describe the POWERLOGIC (SY/MAX) protocol and do not mention Modbus; the Modbus mapping of the same register numbers is the POWERLOGIC convention and has not been checked on a device.",
    "Currents, voltages, power and frequency are 16-bit values scaled by the scale group registers 2020-2025 (powers of ten, default 0); this map reads them with scale_factor.",
    "Power factor is signed magnitude: bits 0-9 hold 0-1000 (thousandths), bit 15 is set for lagging.",
    "Each energy value takes 4 registers, each holding 4 decimal digits (0-9999). The manual does not say which register holds the lowest digits; they are listed one by one so they can be combined once the order is checked.",
    "Factory settings: device address 1, 9600 bps, even parity (commands 2325/2326 switch between even and no parity).",
    "The manual lists many more registers (minimum/maximum values, dates and times, alarms, logs, harmonics); only the main ones are here.",
    "Written from the manufacturer's manual; not tested on a device."
