Welcome aboard the Nexus Network!
Thank you for choosing FI-30 and welcome to the world of the Nexus Network.
Through this manual we would like to help you install, operate and understand your
new Nexus Network.
The Server is the "heart" of your Nexus Network, to which transducers for speed,
depth, heading, wind and navigation (GPS) are connected.
From the Server the single Nexus Network cable transmits power and data to the
instruments, which repeat the information sent from the Server, or other FI-30
transducers.
The Nexus Network is designed with the industry standard RS 485 databus, which
allows you to connect up to 32 FI-30 instrument units on the single Nexus Network
cable, thereby allowing you the flexibility to easily develop your system. The Nexus
Network is capable of carrying data 10 times faster than NMEA 0183.
The connection system, with a single 5 mm (1/5") cable and 4-pole jack plugs with
cable protectors, makes the installation easy. No need to drill big holes and the cable
can be cut to exact lengths. The connections at the Server are colour coded and
marked with a number for easy reference.
FI-30 Multi Control is a multi function instrument that displays a main and a sub-
function together. You can easily "customise" your favourite combination of functions,
by using the unique method to move, copy and lock a sub-function.
The instruments large display gives you very good viewing possibilities from any
angle, even in bright sunlight. The display and the five push-buttons have red back
lighting which you can set to three different lighting levels.
A large selection of optional analogue repeaters and accessories are available. The
analogue steer pilot instrument particularly offers unique functions. When used
together with the steer reference function (AWA), you can actually steer after the wind
and "expand" the tacking or down wind angle.
To get the most out of your new FURUNO product, please read through this manual
carefully before you start your installation.
Again, thank you for choosing FURUNO. If you see us at a show, stop by and say
hello.
Good luck and happy boating!

2Installation
•The installation includes 6 major steps:
1. Read the operation manual.
2. Plan where to install the transducers, Server and instruments.
3. Install the transducers, then the Server and instruments.
4. Run the cables.
5. Take a break and admire your installation.
6. Learn the functions and calibrate your system.
•Before you begin drilling ... think about how you can make the installation as neat
and simple as your boat will allow. Plan where to position the transducers, Server
and instruments. Think about leaving space for additional instruments in the future.
•A few "do nots" you should consider:
−Do not cut the cables too short. Allow extra cable length at the
Server so it can be disconnected for inspection without having to
disconnect all attached cables.
−Do not place sealant behind the display. The instrument gasket
eliminates the need for sealant.
−Do not run cables in the bilge, where water can appear.
−Do not run cables close to fluorescent light sources, engine or radio
transmitting equipment to avoid electrical disturbances.
−Do not rush, take your time. A neat installation is easy to do.
•The following material is needed:
Wire cutters and strippers
Small and large philips and small flat head screw driver
Hole saw for the instrument clearance hole 63 mm (2½")
2.8 mm (0.11") drill for the mounting holes
Plastic cable ties
If the cable is not long enough, you can buy the optional 8 m (26 ft) extension
cable. The same 4-pole FI-30 cable is used for all connections.
If you are doubtful about the installation, obtain the services of an experienced
technician.

2.1 Location of the Server
The Server must be mounted on a dry, flat and vertical surface below deck , at least
500 mm (20") from radio receiving equipment.
Locate the Server in the centre of the boat and close to the electrical panel if possible.
2.2 Installing the Server
Remove the Server cover from the base plate by removing the two screws. Drill the 4
screw holes using a 2.8 mm (0.11") drill. Mount the Server using the 4 mounting
screws.
Apply silicon paste on the screw terminal. Connect the 8 m Nexus Network cable
labelled number 5 and supplied with cable protectors to the Server on pins 5, 6, 7, and
8. Match the colour codes for each wire.
Note: If the cable must be cut, it is recommended it is cut at the unmarked cable
end, since a marked cable is easier to identify.

10
When all connections are made, use the cable straps as required. Mount the Server
cover using the 2 mounting screws.
Your Server installation is done!
2.3 Installing the transducers
Log, depth, wind and compass transducers are all connected to the pins on the right
hand side of the Server. They are all clearly colour coded and marked with numbers
and names. Install the transducers according to the separate instructions supplied with
each transducer. Connect as per below drawings
2.4 Connecting optional accessories
These optional accessories are available from your local FURUNO Dealer. (For a more
complete list of accessories available, see 4.3).

11
2.4.1 Man over board (MOB) push-button
White wire to Server pin 16 (MOB). Brown wire to Server pin 12 (0V).
(For function explanation, see Multi Control Manual)
2.4.2 Tactical function push-button

(For function explanation, see Multi Control Manual)
2.4.3 Extra alarm buzzer
The extra buzzer (105 dB at 15 cm, not water proof) can be mounted where you want a
louder sound. The buzzer will sound as soon as any alarm function is activated in the
Nexus Network.
Red wire to Server pin 9 (+ 12V ). Or 12V from switch panel
Black wire to Server pin 14 (BUZZER).

12
2.4.4 FI-30 instruments
All FI-30 instruments are connected directly to the Nexus Network in a daisy chain.
They all use the same colour coded 4-pole jack plugs. (For instrument installation, see
instrument manual).

13
2.5 Connecting instrument lighting
The instrument lighting can be controlled from the boats general lighting switch.
Connect the wire from the electrical panels instrument light switch to Server pin 13
(LIGHT ON +12 V).
2.6 How to use the NMEA ports
The FI-30 Server is designed with two NMEA input ports and one shared output port.
The external NMEA data will be combined with FI-30 sensor data so that all
information will be available on one single output NMEA port.
One NMEA port (in/out) is dedicated for your PC and follows the RS232 electrical
standard. A 9-pole D-SUB connector is placed at the bottom of the Server.
The Other port (in/out) is accessed at the screw terminal and follows the NMEA 0183
electrical standard (RS422 out and opto-coupler input).
The two-port Server installation will solve most of the integration needs onboard, the
installation with a GPS connected to port A and the Laptop PC on port B.
1. Position, speed and course information is taken from port A (the GPS). The Server
will then pass that information plus all other boat-data to port B where the PC and
chart navigation software will calculate BTW, DTW and XTE information to the FI-
30 instruments, radar, auto-pilot, plotter or other source.
The NMEA ports have been given different priority's depending on the type of data that
will come into the Server when the same type of data comes on both ports.
Position and time (GPS) data GGA, GLL, GSA, GSV, RMC, ZDA have higher
priority on port A.
Navigational data (RMB, BWC, BWR, XTE, APA, APB WPL, BOD WCV ) have
higher priority on port B.
Compass

By using this feature, you may use the PC for planning and part time navigation, then
allow for a GPS/ plotter to take over navigation without the need to change
connections.
Note!
A Laptop PC may have a GPS PCMCIA card installed and deliver position and time
data. However, if the same data is coming in on port A where position have a higher
priority, that data will be used prior to the data from the PC.
This three-port combination proposal will add several advantages. Navigation can be
made from that instrument or it can be used as a repeater, showing data from the
Laptop PC or from a GPS placed at the navigation table below deck. The GPS
instrument can be used as the primary navigator, the backup or as repeater only.
2. Position, speed and course is received from any GPS receiver. Whenever there is
a need to get use of three NMEA input ports, this is the recommended way.
Additional NMEA compass, wind-transducer or depth-sounder transmitting NMEA
can then be added.
Note!
NMEA transducers may degrade the FI-30 system performance and accuracy. For
highest performance only use FI-30 transducers.
2.7 Connecting a NMEA instrument IN to the Server
Products transmitting NMEA, for example:
GPS, Decca, Loran, NMEA compass and wind transducer etc.
If a NMEA instrument is connected, most information will be available and can be
displayed on the Nexus Network.
You must know which 2 cables from your other NMEA instrument carry the NMEA out
signal. If you have trouble call the dealer you bought your NMEA instrument from. He
should know the wiring colour and will probably sell the "plug set" which may be
required. We do not have this information.
Connect NMEA out signal from the NMEA instrument to Server pin 10 (INPUT A).
Connect NMEA return signal from the NMEA instrument to Server pin 11 (INPUT B).
(For list of NMEA receive sentences, see 2.10.3).

15
Note a: The Server allows only one NMEA instrument connected to the input pins
10 and 11.
Note b: We do not recommend the use of NMEA transducers like wind and
compass, because the update rate of data is slow compared to the very fast FI-30
data bus.
Note c: If the NMEA instrument has only one output cable, put a "bridge" cable
on the Server between pins 11 (INPUT B) and 12 (0V GND).
2.8 Connecting a NMEA instrument OUT from Server
Products receiving NMEA, for example:
Plotter, radar, Maxi repeaters, POWER Navigate.
Again you must know which 2 cables from your other NMEA instrument carry the
NMEA in signal. If you have trouble call the dealer you bought the NMEA instrument
from. He should know the wiring colour and will probably sell the "plug set" which may
be required. We do not have this information.
Connect NMEA in signal from NMEA instrument to Server pin 3 (OUTPUT A). Connect
NMEA return signal from NMEA instrument to Server pin 4 (OUTPUT B). (For list of
NMEA transmit sentences, see 2.10.1.)
2.9 Connecting the power supply
1. Connect the red wire from the Server pin 1 (+12V) to +12V.
Connect the black wire from the Server pin 2 (0V) to 0V.
Protect the circuit with a 3 Amp fuse/circuit breaker on the 12V side.

2.10 Compatibility with our previous transducers
2.10.1 Log transducer
All our log transducers can be used for speed and distance.
Only transducers from FI-30 series are able to measure water temperature.
Note: On the Power transducer the white cable (for water temperature) should be
isolated and not installed.
2.10.2 Depth transducer
Only our depth transducers for FI-30 can be used.
Note: Do not mix with transducers from other series.

17
2.10.3 Wind transducer
All our wind transducers can be used.
2.10.4 Compass transducer
Only the FI-30 version can be used.

18
2.10.5 NMEA transducers
NMEA compass, NMEA wind, NMEA log and NMEA depth transducer may be used.
You must know which 2 cables from your other NMEA transducer carry the NMEA out
signal. If you have trouble call the dealer you bought your NMEA instrument from. He
should know the wiring colour and will probably sell the ”plug set” which may be
required. We do not have this information.
Connect NMEA out signal from the NMEA transducer to Server pin 10 (INPUT A).
Connect NMEA return signal from the NMEA transducer to Server pin 11 (INPUT B).
Note a: The Server allows only one NMEA transducer or instrument connected to
the input pins 10 and 11.
Note b: Make sure the calibration codes C73, C74, C75 and C76 (See Multi
Control Manual) for NMEA transducers are correctly set.
