    "Modbus RTU; every value is a holding register. The document numbers the registers from 1 relative to 40.000 and does not say whether that number is sent as is; it is used here as the address on the wire. If every value looks shifted by one register, use address base 1.",
    "The baud rate is detected automatically (1200 to 57600 bit/s) unless fixed; the parity can be none, even or odd. 9600 8N1 is assumed here.",
    "Readings, limits and setpoints are raw values: the number of decimal places is set per sensor (registers 11-13), and the unit depends on the sensor type (°C for RTDs).",
    "The settings for alarm actions, setpoints, hysteresis, analogue outputs and relays (registers 15-123) are left out: the document gives a scale of -1000 for many of them without explaining it.",
    "Written from the register map; this map has not been tested on a device."
