    "All registers are holding registers. The document numbers them 2 to 89 and calls the type Read 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 78.",
    "Temperatures are shown in the document with one decimal 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 with a scale of 1:10, 1:100 or 1:1000 are scaled as written.",
    "Registers 17, 19, 23, 30, 48, 66, 67, 68 and 71 are bit fields, one entry per bit. The command bits 3 to 5 of register 19 are write-only. Registers 1, 44, 45, 49, 53, 54, 72, 73 and the fan state registers 69 and 70 (their labels repeat the shutdown labels) are not mapped.",
    "The document has several copy-and-paste slips; where a label is clearly wrong the register description says how it was read (winding 2 alarm bit, oil shutdown bit, the fan drive bits).",
