Das Furuno NAVnet 2 Network on Board.
ELECTRONIC NAV CHART MODULES
When choosing an electronic nav chart system, everyone has his own
preferences. FURUNO offers two different configurations: C-Map
or Navionics + FURUNO (please
specify it with your order). The chart moduls are available in the following
formats: C-Map NT+ FP, Navionics
Nav-Chart (for Navnet) or C-Map
NT+ SD, Navionics Gold
SD (for Navnet 2) . In a NAVnet system just one chart module is necessary,
because the data are available via Ethernet in all connected NAVnet instruments.
NETWORKING WITH THE NAVnet SYSTEM
A system consists of max. 4 instruments. Radar, Plotter and EchoSounder
sensor set are named as one instrument. Every combination, even with monochrome-
and colour displays, is possible. 2 instruments are connected with a cable,
when you have more instruments, a hub is interposed. Compass
sensor PG- 1000 and GPS sensor GP- 310B can additionally be integrated
via direct connection (without hub). With a complete NAVnet system, consisting
of Radar, Plotter, EchoSounder sensor set, ARPA, GPS-, compass sensor
and chart module every information is available on every active display
(Radar Overlay only on colour displays). Due to security reasons,
TV / DVD / Video are not transmitted; when needed, every 10,4
colour display has to be equipped with a separate PAL / NTSC video
kit. To these instruments, a commercial PC Monitor can be connected as
a passive slave display (RGB kit required).
Compared to other manufacturers, in the NAVnet System not only a separate
display of Plotter or Radar as a single
or dual display is possible, but also a direct overlay of radar pictures
on the Plotters nav charts. This Radar Overlay called function, is an outstanding
feature of the NAVnet series. It makes the radar navigation a lot easier;
coastal marks, buoys etc. can be identified at once! Radar Overlay is possible
on all NAVnet Colour displays ,
when a PG-1000 Compass
and a GP-310B GPS sensor are integrated besides the Radar and Plotter with
a chart module.
After the installation of the ARP-11, ARPA (Automatic Radar Plotting
Aid) is available at the radar instrument and it follows up to 10 selected
targets. On the radar display the distance, bearing, speed, closest approach
and moment of closest approach of the selected targets is shown - a invaluable
help in crowded waters. The ARP-11 is available as an option for the 10
and 10,4 radar instruments , the ARPA data are received via Ethernet
from all connected NAVnet Radar instruments and Plotters. To use the ARPA
function, compass data in the AD-10 format and GPS data have to be available(look
at COMPASS DATA and GPS
Besides the typical full page screen mode (only Plotter or only
Radar or only EchoSounder or...), you have the possibility to define your
own display out of different pictures with the NAVnet
instruments. Depending on the instrument, a double or triple subsivision
of the display is possible. In a complete NAVnet system you have the choice
between more than 50 different combinations, 5 or 6 of these(depending
on the instrument) can be saved as individual Hot Pages for a fast recall.
With the colour displays, different colour variations are available, e.g.land
/ sea, background / Radar echos, waypoints, markers etc.
To display the different Radar- and Plotter-modes (e.g. True Motion,
ARPA and Radar Overlay) compass- and speed data have to be available. The
speed data are transmitted from the GPS (GPS sensor or with the NMEA input),
but for the compass data an electronic compass with the output of HDG data
or data in AD-10 format is required. To use the ARPA function, only
AD-10 data are accepted. We recommend the Furuno PG-1000
Compass sensor, it sends data in AD-10 format precisely and stable,
even when the yacht is pitching and rolling. So every Radar- and Plotter-
mode is guaranteed.
ECHOLOT SENSOR SET
This is necessary, to use the EchoSounder software of the NAVnet
instruments and it consists of a Transceiver box ETR-6/10N with up to 1000W
RMS (=8000W p/p) transmitting power, dual frequency mode(50/200 kHz) and
EchoSounder sensor. Various types of sensors for through-hull - or stern
mounting are availabel. Also the maximum depth is dependent on the
sensor (up to 1200 m). When there is only one instrument, the transceiver
box is connected directly, with two or three instruments the connection
is made using the hub, that takes over the data transfer.The box works
with a board voltage of 12 V/24 V.
GPS SENSOR GP-310B
To use the NAVnet Chart Plotter- and Nav data displays, GPS data are
necessary, either via NMEA input or via connection to the GP-310B sensor.
A 12 channel parallel receiver and an antenna are housed in this only 11
x 7 cm in diameter spraywaterproof enclosure. It has to be connected to
the NAVnet instrument and then it supplies the complete system with precise
Beside the user friendly, multilingual menu, it is a great benefit,
in a big system, when all instruments have the same actuators. Therefore
in the NAVnet system FURUNO has allocated every instrument the same keyoard
- you don´t have to use different keyboards all the time while
navigating with different instruments! As a bonus, the 10,4
Colour-LCD Monitors are equipped additionally with an alphanumerical
keyboard for an easy input of waypoints, routes,etc.
For all 10,4 NAVnet instruments
(Radar and Plotter!) a video board in PAL/NTSC format is available. After
the installation, films can be played in on the colour display via Videorecorder-,
TV-, DVDPlayer- or camera connection (full screen or split screen). This
is perfect in a boring night watch or supervision with fix mount cameras
(when more than one camera is connected, a camera switch is necessary).
The video dasta are not distributed via Ethernet; if required, each 10,4
NAVnet instrument has to be equipped individually with a video board.
With the Furuno FAX-30 blackbox
you also get weather charts and Navtex information on all 10,4 NAVnet
instruments (Radar and Plotter!).
