Unofficial: Copied from an unofficial source and not tested. Read it as a draft and check a value on the real device before you rely on the rest. Check the map against the manufacturer's documentation before you write to a live device. Tested it? Report a test.

Sources and notes

Source: "Modbus register DEEPSEA 86XXX", 7-page register excerpt (GenComm pages 4 and 8), not a Deep Sea Electronics publication

  • Address = page * 256 + offset: page 4 (base 1024) holds the basic instrumentation and page 8 (base 2048) the named alarm conditions.
  • 32-bit values are sent high word first. Signed values are marked as such in the excerpt.
  • Each named alarm register holds four 4-bit alarm conditions, the first alarm in bits 12-15.
  • Unimplemented or out-of-range values read as the GenComm sentinel values (0xFFFF, 0x7FFF, ...).
  • Serial settings follow the controller configuration; the 9600 8N2 values here are the GenComm defaults used by the other DSE maps.
