    "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."
