FOREWORD
A Word to DD-80 Owners
Congratulations on your choice of the
FURUNO DD-80 dual differential GPS navigation system. We are confident you will see
why the FURUNO name has become synonymous with quality and reliability.
For over 50 years FURUNO Electric Company has enjoyed an enviable reputation for
innovative and dependable marine electronics equipment. This dedication to excellence
is furthered by our extensive global network
of agents and dealers.
This equipment is designed and constructed
to meet the rigorous demands of the marine
environment. However, no machine can perform its intended function unless operated and
maintained properly . Please carefully read and
follow the recommended procedures for operation and maintenance.
We would appreciate hearing from you, the
end-user, about whether we are achieving our
purposes.
Thank you for considering and purchasing
FURUNO equipment.
The main features of the DD-80 are
• Comprehensive navigation data displays
• Storage for 999 waypoints and 30 routes
• Alarms: Arrival, Anchor Watch, Crosstrack Error, Speed, Water Temperature,
Depth, and Trip
• Man overboard feature records latitude and
longitude coordinates at time of man overboard and provides continuous updates of
range and bearing to that point
• Menu-driven operation
• Bright 122 x 92 mm LCD with temperature compensated tone and brilliance adjustment
• Power consumption is a low 10 W per navigator.
• Connection of autopilot (option) – steering data output to autopilot
• Digital display of water temperature and
depth with connection of video sounder
having IEC 61162-1/NMEA input
• Memory stores 2,000 points of track and
marks
• 3D "Highway" display shows ship's track
overlaid on intended course
• Position may be shown in latitude and longitude or LOP (Loran or Decca)
• Navaid information (lighthouse data,
lighted buoys, etc.) can be displayed by
downloading database from personal computer.
Features
The DD-80 consists of two dual differential
GPS navigator systems and an interface unit.
Each GPS navigator consists of a display unit
combining a GPS receiver, beacon receiver
and video plotter, a GPS antenna and a beacon antenna. The interface unit functions to
exchange data between the GPS navigators
and external equipment. A high sensitivity
receiver tracks up to eight satellites simultaneously . An 8-state Kalman filter ensures optimum accuracy in determination of vessel
position, course and speed.

1.2 Turning On and Off the Power
The DD-80 takes about two minutes to find
position when turned on for the very first time.
Other times it takes about 20 seconds.
Note: The GPS provides highly accurate po-
sition information. However, position should
always be check against other aids to navigation to confirm reliability, for the safety of
vessel and crew.
Turning on the power
Press the [POWER] key.
The unit tests the PROGRAM MEMORY,
SRAM and battery for proper operation and
shows the results on the display. "BEACON
RCVR INSTALLED" appears at the bottom
of the display . The unit starts up with the last
used display mode and that mode is indicated
at the bottom of the display.

1.5 Transmitting Data
The GPS navigators share the data listed below when transmitting data to each other . Any
action initiated against those data is automatically repeated on the other navigator . For example, if you register waypoint 27 on one
navigator it will be registered on the other
navigator under the same waypoint number.
• Alarm settings, alarm buzzer
• Destination data
• Disabled satellite data
• Error messages
• MOB/Event mark data
• Route data
• Waypoint data

Data is transmitted only once. When transmission error occurs, the following message

1.6 The Interface Unit
The Interface Unit IF-2500 outputs data received from the navigators to external equipment. Operational status is shown by the LEDs
on the unit. For further details, see APPENDIX B of this manual. For how to select data
to output, see paragraph 8.4 Outputting Data.
Output data conventions
Figure 1-20
Press any key to erase the message. Follow
"Transmitting data" in this paragraph to transmit data again.
Since both navigators output data to the IF2500 (through two ports on the interface) confusion would reign if it were to try to output
two sets of mostly identical data. Therefore,
data output is governed by the following rules:
• When both navigators are outputting data
correctly, data received at the port having
higher priority is output.
• When the GPS abnormal receive signal is
received at the port having higher priority,
data received from the other port is output.
• 30 seconds after data received at the port
having higher priority becomes normal,
the interface resumes outputting data received from that port.
• When data from both navigators is in er-
ror, data received at the port having higher
priority is output.
• Arrival alarm signal or cross track error
alarm is converted to a contact signal and
output when received at the port having
higher priority.
• When no data is received from one or both
navigators, a contact signal is output.

You may enlarge/shrink the display on the

[ZOOM IN] and [ZOOM OUT] keys. The
horizontal range is available among 0.25, 0.5,
1, 2, 4, 8, 16, 32, 64, 128 and 192 nautical
miles. For the Plotter 1 display the ranges are

45.51, 91.02, 182.04 and 273.07 nautical

The [ZOOM IN] key enlarges the display and
the [ZOOM OUT] key shrinks it. Each time a
zoom key is pressed the horizontal range appears at the center of the display for about

Ship's heading or course is at the top of the
display . The north mark appears at the left side
of the display.
2.3 The Cursor
The cursor (+) functions to measure the select location for a mark; erase marks, measure range and bearing, etc.
Data and cursor state
Cursor state determines what data are shown
on the display.
Cursor turned on
Cursor position is displayed in latitude and
longitude or LOPs (depending on menu setting) at the top of the display. The range and
bearing from own ship to the cursor appear at
the right hand side of the display , when in the
Plotter 1 display.
Display orientation can be selected on the
Plotter 1, Plotter 2 and Highway displays, with
the [NU/CU ENT] key. Two display orientations are available: north-up and course-up.
North-up display
In the north-up display, true north (0°) is at
the top of the display . Own ship moves on the
display in accordance with true speed and true
motion. Land is stationary.
Course-up display
Destination set
The destination is at the top of the display and

and Recording of T rack
The DD-80 stores 2,000 points of track and
marks. When the memory becomes full the
oldest track is erased to make room for the
latest. Thus you may want to conserve the
memory when, for example, you are returning to port or are anchored, by stopping plotting and recording of the track.
Procedure
Press the [PLOT ON/OFF] key to start/stop
recording and plotting of track.
When plotting is resumed
"Resuming track plot" appears at the center
of the display for about three seconds.

2.8 Track Plotting Interval
The plotting interval determines both how the
track will be reconstructed on the display and
track storage time. A shorter interval provides
more accurate reconstruction of track line,
however total storage time is reduced. The
plotting interval can be selected by time or
distance. Plotting by distance offers the advantage that the track is not stored when the
vessel is anchored.
Plotting interval by time
The setting range for plotting by time is 00 to
60 minutes.

enter 30 seconds, for example, press [0]

points each of track and marks.
Note: All data are erased when the memory
apportion setting is changed, even when the
previous value is reentered.
