Depth
The NMEA sentences DPT, DBS, DBT, DBK and PSKPDPT are all supported for
receiving information about the depth. The use of the DPT sentence is recommended
when available. Depth values in feet and fathoms (from DBK, DBT and DBS) are
converted to meters. The screen will display either DEPTH-S (depth below surface),
DEPTH-T (depth below Transducer) or DEPTH-K (depth below keel) depending of
the received sentences (DBS, DBT or DBK) or the oset value in DPT. The proprietary
sentence PSKPDPT is able to distinguish between both transducer location and channel
number. The transducer location is indicated by an arrow in the text line. The channel
number is selected by parameter PDPT1, PDPT2 or PDPT3 and is written in the text
line as DPT1, DPT2 or DPT3 respectively for each channel. The parameter name PDPT
will ignore channel number and is written in the text line as DEPTH.
The depth is always displayed in meters. Depth values below 10 meters are displayed
with 2 decimals, depth values between 10 and 100 meters are displayed with 1 decimal
and depth above 100 meters are displayed without decimals.
Maximum depth value to be displayed is 9999 meters.
