This map covers the 19000-19120 'frequently required readings' block (volts, amps, power, PF, frequency, energy, THD), total power factor, the bus and transformer parameters, the digital output source and the reset commands.",

  "Byte order: the list says its addresses return data big-endian (high byte first, high word in the lower register = ABCD). Adding 32768 to an address returns the same value little-endian; that mirror block is not listed.",
  "Unlike other Janitza lists, 19044-19048 are printed as 'power factor' (not CosPhi), 19068 is the consumed L1-L3 total, and the rotation field 19052 is an int (signed 32-bit) rather than a float.",
  "Transfer parameters (p. 5): 9600, 19200 or 38400 baud, 8 data bits; the page names odd/even parity and 1 or 2 stop bits, while parameter 2 also offers stop-bit-only framing. The list gives no defaults, so defaults are left blank.",
  "Parameter 0 is printed with a range of 0-255 and a footnote mark whose text is not on the page; use 1-247 for a normal Modbus slave address.",
  "Left out: display, averaging-time and threshold parameters, the pulse valence at 102 (range given but no unit beyond 'e.g. imp/kWh'), tariff assignment bits, mean/min/max blocks, tariff energy and the double-type energy copies.",
  "The address list names no physical interface (RS-485) or framing mode (RTU); RTU is assumed from the serial baud/parity parameters. Confirm in the device user manual."
