    "All registers are holding registers. The document numbers them 1 to 38 and calls the type Holding Register (40.000), so the addresses are 1-based (address on the wire = number minus 1). The document does not say so explicitly: if a read fails, try address_base 0.",
    "The document allows 1200 to 57600 bps with automatic baud rate detection, 8 data bits, 1 stop bit and no, even or odd parity. It gives no default baud rate or slave address: 9600 N and 1 are placeholders; the slave address is in register 23.",
    "Temperatures are shown in the document with one decimal (for example -50.0 to 250.0) and a scale of -1000:10, which it does not explain. They are given as raw values: check against the display before applying a scale.",
    "Registers 17, 19, 32, 33, 34, 35 and 37 are bit fields, one entry per bit. The command bits are write-only. Registers 27, 28 and 36 are not in the document.",
