2. Output Data Format
1) DPT – Depth
$--DPT,x.x,x.x,x.x*hh<CR><LF>
1 2 3
1: Water depth relative to the transducer, in meters
2: Offset from transducer, in meters 1) 2)
3: Maximum range scale in use
Note;
1) “positive” = distance from transducer to water line; “-“ = distance from transducer to keel.
2) For IEC applications, the offset should always be applied so as to provide depth relative to
the keel.
2) DBT – Depth below transducer
$--DBT, x.x, f, x.x, M, x.x, F*hh<CR><LF>
1 2 3
1: Water depth, feet
2: Water depth, meters
3: Water depth, fathoms
