Garmin AQUAMAP 80 Series, Owner'S Manual

Page: 29 / 36

Serial Port 1 : Sets the input/output format for port 1 to use
when connecting the chartplotter to external NMEA devices,
computers, or other Garmin devices.
Serial Port 2 : Sets the input/output format for port 2 to use
when connecting the chartplotter to external NMEA devices,
computers, or other Garmin devices.
NMEA 0183 Setup : Sets the NMEA 0183 sentences the
chartplotter transmits, how many digits to the right of the
decimal point are transmitted in a NMEA output, and how
waypoints are identified ( NMEA 0183 Settings , page 23 ).
Marine Network : Allows you to view the devices with which you
are sharing maps, sonar, or radar. Not available on all
chartplotter models.
NOTE: You can only view networked data on a model that
supports that data. For example, you cannot view networked
radar on model that does not support radar.
NMEA 0183
The chartplotters support the NMEA 0183 standard, which is
used to connect various NMEA 0183 devices, such as VHF
radios, NMEA instruments, autopilots, wind sensors, and
heading sensors.
To connect the chartplotter to optional NMEA 0183 devices, see
the chartplotter installation instructions.
The approved NMEA 0183 sentences for the chartplotter are
GPAPB, GPBOD, GPBWC, GPGGA, GPGLL, GPGSA, GPGSV,
GPRMB, GPRMC, GPRTE, GPVTG, GPWPL, GPXTE, and
Garmin proprietary sentences PGRME, PGRMM, and PGRMZ.
This chartplotter also includes support for the WPL sentence,
DSC, and sonar NMEA 0183 input with support for the DPT
(depth) or DBT, MTW (water temperature), and VHW (water
temperature, speed, and heading) sentences.
NMEA 0183 Settings
Select Settings > Communications > NMEA 0183 Setup .
Sounder : Enables NMEA 0183 output sentences for the
sounder (if applicable).
Route : Enables NMEA 0183 output sentences for routes.
System : Enables NMEA 0183 output sentences for system
information.
Garmin : Enables NMEA 0183 output sentences for Garmin
proprietary sentences.
Posn Precision : Adjusts the number of digits to the right of the
decimal point for transmission of NMEA output.
Waypoint IDs : Sets the device to transmit waypoint names or
numbers via NMEA 0183 while navigating. Using numbers
may resolve compatibility issues with older NMEA 0183
autopilots.
Diagnostics : Displays NMEA 0183 diagnostic information.
Defaults : Restores the NMEA 0183 settings to the original
factory defaults.
Setting Alarms
Navigation Alarms
Select Settings > Alarms > Navigation .
Arrival : Sets an alarm to sound when you are within a specified
distance or time from a turn or a destination.
Anchor Drag : Sets an alarm to sound when you exceed a
specified drift distance while anchored.
Off Course : Sets an alarm to sound when you are off course by
a specified distance.
System Alarms
Alarm Clock : Sets an alarm clock.
Device Voltage : Sets an alarm to sound when the battery
reaches a specified low voltage.
GPS Accuracy : Sets an alarm to sound when the GPS location
accuracy falls outside the user-defined value.
Units Settings
Select Settings > Units .
System Units : Sets the unit format for the device.
Variance : Sets the magnetic declination, the angle between
magnetic north and true north, for your present location.
North Reference : Sets the direction references used in
calculating heading information. True sets geographic north
as the north reference. Grid sets grid north as the north
reference (000º). Magnetic sets the magnetic north as the
north reference.
Position Format : Sets the position format in which a given
location reading appears. Do not change this setting unless
you are using a map or chart that specifies a different
position format.
Map Datum : Sets the coordinate system on which the map is
structured. Do not change this setting unless you are using a
map or chart that specifies a different map datum.
Pressure Ref. Time : Sets the reference time used to calculate
the barometer trend. The trend is indicated in the barometer
field.
Time Format : Sets a 12-hour, 24-hour, or UTC time format.
Time Zone : Sets the time zone, or allows automatic selection
based on GPS location.
Navigation Settings
NOTE: Some settings and options require additional charts or
hardware.
Select
Settings > Navigation .
Route Labels : Sets the type of labels shown with route turns on
the map.
Auto Guidance : Sets the measurements for the Safe Depth,
Safe Height, and Shoreline Distance, when you are using
some premium maps.
Turn Transition Activ. : Sets the turn transition to be calculated
based on time or distance.
Turn Transition Time : Sets how many minutes before the turn
that you transition to it as the next leg, when Time is selected
for the Turn Transition Activ.. You can raise this value to help
improve the accuracy of the autopilot when navigating a route
or an Auto Guidance line with many frequent turns or at
higher speeds. For straighter routes or slower speeds,
lowering this value can improve autopilot accuracy.
Turn Transition Dist. : Sets how far before the turn that you
transition to it as the next leg, when Distance is selected for
the Turn Transition Activ.. You can raise this value to help
improve the accuracy of the autopilot when navigating a route
or an Auto Guidance line with many frequent turns or at
higher speeds. For straighter routes or slower speeds,
lowering this value can improve autopilot accuracy.
Route Start : Selects a starting point for route navigation.
Auto Guidance Line Configurations
CAUTION
The Safe Depth and Safe Height settings influence how the
chartplotter calculates an Auto Guidance line. If an area has an
unknown water depth or an unknown obstacle height, the Auto
Guidance line is not calculated in that area. If an area at the
beginning or the end of an Auto Guidance line is shallower than
the safe water depth or lower than the safe obstacle height, the
Auto Guidance line is not calculated in that area. On the chart,
the course through those areas appears as a gray line. When
your boat enters one of those areas, a warning message
appears.
