Display the window shown above. The format changes each time you press the up or
downward-arrow key.
Notes:
1. There are three output formats: NMEA0183V2.3, NMEA0183V1.5, or ALL.
2. In the case of NMEA0183V2.3, only "SDDPT" sentences are output.
$SDDPT, xxx.x, x.x, x.x *hh (CR)(LF)
(1) (2) (3) (4)
(1) Depth measured from the transducer regardless of the depth display mode setting (in
meters only.)
(2) According to the depth display mode:
DISP-SURF: Draft value (no + or – sign preceding values)
DISP-TRANS: 0.0
DISP-KEEL: Keel height compensation (– sign preceding values)
(3) Measuring range: RANGE (in meters only)
(4) Checksum (result after each ASCII code of every character between "S" just after "$" and
"X" just before " * " is EXORed.)
3. In the case of NMEA0183V1.5, the output sentence varies according to the depth display
mode setting.
• When DISP-SURF is set, only the "SDDBS" sentence is output.
$SDDBS, xxx.x, f, xxx.x, M, xxx.x, F(CR)(LF)
(1) (2) (3)
• When DISP-TRANS is set, only the "SDDBT" sentence is output.
$SDDBT, xxx.x, f, xxx.x, M, xxx.x, F(CR)(LF)
(1) (2) (3)
• When DISP-KEEL is set, only the "SDDBK" sentence is output.
$SDDBK, xxx.x, f, xxx.x, M, xxx.x, F(CR)(LF)
(1) (2) (3)
The field values are the same in each of the three sentence types:
(1) Depth value after compensation (in feet)
(2) Depth value after compensation (in meters)
(3) Depth value after compensation (in fathoms)
(4) No check sum
