PULSE OUTPUTS
There is one output channel with possibility for two galvanically separated
output drivers. It is possible to set number of pulses per nautical mile (p/nm)
for the optocoupled outputs.
• Number of pulses per nautical mile: 10, 100, 200 or 400.
NMEA OUTPUTS
EML 224 Compact Transmitted (Originated) NMEA 0183 (IEC61162-1)
Messages
VBW Multiple Speed
Commands
EML: $VMVBW,x.x,y.y,A,,,
V,,V,,V*hh<CR><LF>
DL1: $VDVBW,x.x,,A,,,
V,,V,,V*hh<CR><LF>
Where x.x is longitudinal
speed in knots, y.y is
transversal speed in knots in 2
axis systems.
VLW Distance
Travelled
through the
Water
EML: $VMVLW,x.x,N,y,N,,
N,,N*hh<CR><LF>
DL1: $VDVLW,x.x,N,y,N,,
N,,N*hh<CR><LF>
x.x is daily trip, y.y is total trip
in NM
MTW Temperature EML: $VMMTW,x.x,C,
*hh<CR><LF>
DL1: $VDMTW,x.x,C,
*hh<CR><LF>
x.x is temperature in Celsius.
All data elds are free format.
Values will be presented with
sign as needed ( e.g “-“ =
astern, port)
VHW Water speed
and heading,
relative
EML: $VMVHW,,,,x.x.N,
x.x,K *hh<CR><lf>
DL1: $VDVHW,,,,x.x.N,
x.x,K *hh<CR><lf>
Resultant speed in knots and
km/h.
XDR Speed
direction
EML: $VMXDR,A,x.x,D,
SPDD *hh<CR><LF>
DL1: $VDXDR,A,x.x,D,
SPDD *hh<CR><LF>
The angular displacement
(x.x) is set to 0 in forward
direction and 180 in reverse
direction.
*hh = Checksum
In addition, some proprietry sentences are available. These can be obtained
by turning on DIAG. (This disables all other NMEA outputs).
