NMEA inputs
The following inputs may be used to enhance the DL1:
GPS
Time
GPVZTG, GPZDA, GPGGA
Time taken from these format
TRIP
Trip reset command
$PSKPRSTT*<hh><CR><LF>
Trip reset from repeaters, etc.
DDC
Display Dimming
control
$DDC,a,xx,a,a*hh<CR><LF>
a is display dimming preset.
D = Day time setting
K = Dusk setting
N = Night time setting
O = Backlighting off setting
xx is brightness percentage 00 to 99.
second a is colour palette.
NMEA outputs
VBW
Multiple Speed
Commands
$VDVBW,x.x,,A,,,V,,V,,V*hh<C
R><LF>
Where x.x is longitudinal speed in knots, y.y is
transversal in 2 axis systems speed in knots.
VLW
Distance Travelled
through the Water
$VDVLW,x.x,N,y,N,,N,,N*hh<C
R><LF>
x.x is Daily Trip, y.y is total trip in NM
MTW
Temperature
$VDMTW,x.x,C,
*hh<CR><LF>
x.x is temperature in Celsius. All data fields are
free format. Values will be presented with sign as
needed ( e.g “-“ = Astern, Port)
VHW
Water speed and
heading, relative
$ V D V H W, , , , x . x . N , x . x , K
*hh<CR><lf>
Resultant speed in knots and km/h.
XDR
Speed direction
$ V D X D R , A , x . x , D , S P D D
*hh<CR><LF>
The angular displacement (x.x) is set to 0 in
forward direction and 180 in reverse direction.
