NMEA DPT datagram

The NMEA DPT datagram provides the water depth relative to the transducer, and the
offset of the measuring transducer.
Format
$--DPT,x.x,y.y,z.z*hh<CR><LF>
Description
This description is not complete. For additional details, refer to the NMEA standard.
1 : Talker identifier
$—
2 : Datagram identifier
DPT
3 : Depth (Metres), Relative to the transducer
x.x
4 : Offset (Metres), Relative to the transducer
y.y
Positive offset numbers provide the distance from the transducer to the water
line. Negative offset numbers provide the distance from the transducer to the part
of the keel of interest.
5 : Maximum range scale in use
z.z
6 : Checksum
*hh
Tip
If you need the depth below the keel, use the NMEA DBK datagram. If you need the
depth below the surface, use the NMEA DBS datagram. If you need the depth below the
transducer, use the NMEA DBT datagram.
