    "Configuration is not permanently saved: the Description sheet states it is set on each power-on. Defaults: counters 0, debounce 0 ms, outputs OFF.",
    "Multi-register values (counters, floats) are taken as big-endian (most significant register first), as in the other Unipi maps; the spreadsheet only says bit 0 is the LSB and bit 15 the MSB.",
    "The spreadsheet does not state the transport or default unit id, so the format defaults (tcp+rtu, unit 1) are kept.",
    "Coils repeat the relay outputs that also appear as bits of holding register 1.",
    "Analog Output 1 is documented as 'int16, 0..4000 ~ 0..10V': mapped as int16 with 0.0025 V per count and a 0-10 V write range. The unit of the analog input floats is not stated in the spreadsheet, so none is set.",
    "The counter of Digital Input 12 is a uint16 (one register) in the spreadsheet; the other counters are uint32."
