2 Installation
• The installation includes 6 major steps:
1. Read the installation and operation manual.
2. Plan where to install the WSI-box, transducers and instruments.
3. Run the cables.
4. Install the WSI-box, transducers and instruments.
5. 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 not” 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 of 63 mm (2½").
Hole saw for the transducers of 43 mm.
2.8mm drill for the WSI-box mounting screws
5 mm (1/4") drill for the mounting holes.
Plastic cable ties
If you are doubtful about the installation, obtain the services of an experienced
technician.

2.1 Installing the instrument
•Place the adhesive drill template on the desired location for the instrument. Drill the
2 holes using a 5 mm (1/4") drill for the two pin bolts. Use a 63 mm (2½") hole saw
to machine the clearance hole for the instrument connection socket. Remove the
template.
•Screw the two pin bolts to the instrument
•Put the instrument in place
•Screw the two nuts from the back
Note! The two nuts must just be tighten by hand only
•Run the Nexus Network cable from the WSI-
box to the instrument.
•If you want to cut the Nexus Network cable to
length, disconnect 4-pole jack plug and cut
the cable. Peel off about 35 mm (1.4") of the
cable insulation. Remove about 6 mm (1/4")
from the 3 isolated wires (the 4th wire is an
earth / screen). Attach the 4 cable protectors
to the wires using a pair of flat pliers.
•Connect the 4 cable protectors to the 4-pole
jack plug as shown. Apply silicon paste on all
locations as shown.
Note: Must be done to avoid corrosion.

2.2 Installing the WSI-box
Remove the WSI-box cover from the base plate by removing the
screw. Drill the 3 screw holes using a 2.8 mm (0.11") drill. Mount
the WSI-box using the 3 mounting screws.
Apply silicon paste on the screw terminal. Connect the 8 m Nexus
Network cable supplied with cable protectors to the WSI-box on
pins 13, 14, 15, and 16. Match the colour codes for each wire.
2.3 Installing the Wind Transducer
2.3.1IMPORTANT Installation information!
BEFORE placing the wind transducer on the mast, a pairing
procedure must be done!
2.3.2Location
The transducer should be mounted on a horizontal surface in the mast head. If the
masthead is not horizontal a shim has to be added. A 15 shim for Seldén masts is
available (art.no 67400-15).
2.3.3Mounting in the mast head
The transducer permits any type of horizontal mounting angle.
Mount the unit by directing the pipe (1) down and backwards in the bracket (2). Secure
the nut (3) towards the attachment BY HAND (tools can be needed when demounting).
Attach the security clamp (4) behind the nut.

2.3.4Mounting the wind transducer step by step
1. Mark the mounting holes using
the bracket as an template
3. Mount the bracket with the three
supplied screws
5. Tighten the lock nut by hand only
(do not use any tool)
2. Drill the three mounting holes
using a 3,2mm drill
4. Insert the transducer into the
bracket from front to back
6. Attach the security clamp

2.4 Installing the Log and depth transducers
2.4.1 Correct location of transducer
Generally the transducers should be placed as far forward as possible along the waterline length
and close to the centreline.
The depth transducer can be mounted on the opposite side from the speed transducer.
If the transducers are mounted on the center line of the boat, the depth transducer should be
mounted about 40cm in front of the speed transducer.
It is important that the transducers are always in the water, within the whole speed range of
the boat. Please note that the actual waterline length of fast power boats shortens considerably at
high speeds. Therefore the transducer should be placed at 25-35% along the true waterline from
the bow, when at full speed
Example:

English Start pack 4
12
Sailboats with a fin keel must have the transducer located at least 25 cm but not more than 75 cm
in front of the keel. It should be placed no more than 10 cm off the centreline.
On sailboats with a pronounced “V” in the hull, such as full-keel yachts, it might be favourable to
angle the transducer slightly so that it aims at the bow, rather than directly parallel to the
centreline.
This will help balanced the passing waterflow measurement from one tack to another.
Avoid placing the transducer near the edge of sharp hull chines. Transverse waterflow in these
areas can affect the accuracy of measurements.
If you have a questions about the location of the through-hull, contact your builder, yacht
dealer, or other owners of similar boats for advice. Always remember to allow for
accessibility from the inside of the yacht when determining the final location.

Start pack 4 English
13
2.4.2 Installing the through hull fittings
1. Use a 43 mm (1 11/16”) hole cutter to cut through the hull. (See section 3 for correct
location).
2. Apply the polyurethane sealing compound on the outer flange of the through-hull fitting and
tighten the nut on the inside by hand.
3. Slide both rubber O-rings on the dummy plug.
4. Generously apply the silicone grease to the exterior of the dummy plug.
5. Install the dummy plug in the through-hull fitting. Use a slow twisting motion and be sure that
is properly seated into the fitting.
6. With the dummy plug properly installed in the through –hull fitting, mount the fitting so that the
handle is exactly at right angles (90º) to the boats centreline. (For pronounced V-hulls see
section 3).
7. When this outer sealant has cured, remove the nut and apply sealant on the inside. Tighten
the nut again by hand.
8. Install the wire locking device onto the dummy plug /paddlewheel transducer.

•Apply silicon paste to the instrument connection pins at the back of the instrument.
Press the jack plug onto the instrument pins. Press the cable in to the cable leads.
•Mount the connection back cover with the screw.
3 Connection to other Nexus systems
A NX system is fully compatible with other Nexus Network system such as NX2. If you
want to connect the NX system to a NX2 system, you have to move the connection of
the log and depth transducers to the WSI box. Note that a 200kHz depth transducer
must be used. The 200kHz transducer is recognized by the colour of the leads that
should be blue, black and screen. If your existing depth transducer has other colours of
the transducer leads, it has to be changed. 200kHz transducers are available for all
types of Nexus through hull fittings.
The Nexus network cable of the NX system may be connected at any location in the
existing Nexus system. That is normally at the NX2 Server but if it is more convenient,
you may connect the NX Network cable to any existing NX2 instrument.
4 Pairing procedure of wind transducer
When all instruments have been installed, a pairing procedure between the wireless
wind transducer and the WSI unit must be made to introduce it to your specific NX
network system. This is how you do it:
a. Make sure the wind transducer is fully charged!
If the wind transducer has been stored in a dark place for a long time,
you must first charge it by exposing the solar cell for sun light some
hours before use.
b. Pairing!
Hold the wind transducer within 2m from the Wireless WSI unit, and
then press the INIT button (through the hole in the bottom of the
battery lid) by use of the “pin”.

English Start pack 4
16
If the batter lid is open, you may see the LED. The built in LED will
flash 2 times then lit for 2s, before it is turned off. Your Nexus system
is now ready for use.
If the pairing of some reason did not work, the LED will flash a third
time. You should then release the WSI-box airing, see below!
5 Re-initialization of the wind transducer
To release the Wind transducer and re-initializing it, press and hold the INIT
button for 5s.
The wind transducer can then be re-initialised again to the same, or to any other
WSI-box as described above.
när den åter skall monteras. Se procedur enligt ovan.
6 Maintenance!
If you have been using the Wireless wind for several seasons, you may need to
change the rechargeable cells.
Use Nexus original NiMh cells.
IMPORTANT! Do not change the rechargeable cell in strong light! If needed, cover
the solar cell with your hand while changing cells!
Open the battery lid and remove the old cell from the connector, install the new
cells. Return the used Cells to waste collection!
7 Change transducer or WSI-box / Release the pairng
If the wireless transducer or the WSI box has to be exchanged, WSI-box piring has to
be released. To release the WSI-box, there are two alteratives:

8 First start
8.1 Initialising the instrument
You will be asked to press SET (PrESkey)
on the instruments the very first time after
installation. This will give the instrument a
logical ID number that belongs to your
specific Nexus Network.
Press SET, on each installed instrument, one
at the time.
Always wait for the text ‘Init OK’
to be displayed, before you
press SET on the next
instrument!
The first unit ID number is 16, then 17 and so
on in the order which you press SET.
The example shows that the Sea Data
instrument version number is 1.0 and that
the instrument was given the logical ID
number 16.. The Wind instrument has
version no. 1.00 and ID number 17
The bottom row in the Sea Data shows the
software version (4.8) and ID number (0) of
the network master (WSI-box or Server).
When the NX WSI-box is network master,
the ID number is 2
When the NX2 Server is network master, the ID
number is 0
