Welcome aboard the Nexus Network!
Thank you for choosing NX2 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, Loran or Decca) 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 NX2
transducers.
The Nexus Network is designed with the industry standard RS 485 databus, which
allows you to connect up to 32 NX2 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.
NX2 Multi Control is a multi function instrument that displays a main and a subfunction together. You can easily ”customise” your favourite combination of
functions, by using the unique method to move, copy and lock a sub-function.
The Multi XL is very similar to the Multi Control but the push buttons has been
removed to increase the size of the display and the digits. The Multi XL is controlled
from a Multi Control instrument. The instruments large display gives you very good
viewing possibilities from any angle, even in bright sunlight. The display 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.
These NX2 instruments carry a two year warranty, which gives you as our
customer, confidence to trust NX2 and our commitment to quality.
To get the most out of your new NX2 product, please read through this manual
carefully before you start your installation.
Again, thank you for choosing NX2. If you see us at a show, stop by and say hello.
Good luck and happy boating!

The installation includes 6 major steps:
Read the operation manual.
Plan where to install the transducers and instruments.
Run the cables.
Install the transducers and instruments.
Take a break and admire your installation.
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").
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.

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
Run the Nexus Network cable from the Server
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.
Silicon paste

First start
3.1
Initialising the instrument
At power on, the instrument will perform a self test. The display will
first show all segments, then the software version number,
instruments ID number, the bus masters ID number and the ID
number of the bus master (normally the Server).
At first power on after installation, the text Auto Init is displayed.
Right of the Init text, a sign is shown. Take the supplied initialisation
magnet and hold it over the sign. A magnetic sensor inside the
instrument will detect that and perform an automatic initialisation of
this instrument.
Proceed with next instrument, one at the time.
Magnet
Note: Always wait for the text ”Init OK”
to be displayed, before you press SET
(with magnet or push button) on the next
instrument!
The Server automatically gives the first unit ID number 16, then 17
and so on. The order in which you press SET (with magnet or push
button) is the same order as the instruments will be given a logical
ID number on the Nexus Network.
The example shows that the instrument version number is 4.0 and
the given logical ID number is 16. On the lower line, the bus master
version number (4.8) and ID (0) is displayed.
3.2
Re-initialising the instrument
If two instruments by mistake have the same ID number, this can
cause disturbance and block the information on the Nexus data
bus.
To re-initialise the instrument, press CLEAR during the power up
sequence on a Multi Control (or other NX2 instrument with push
buttons) when version and ID numbers are displayed.
The display self test is then re-started on all instruments and you will
be asked to press KEY (Init) on each instrument as explained above.
Note! If you do not succeed to re-initialise, we suggest
you disconnect all but one instrument with the same
ID number, then repeat the above procedure.

Operation
4.1
How to operate the Multi XL
4.1.1
General operation
Note! The Multi XL can only be operated by the Multi Control.
When a Multi XL has been initialised on the Nexus Network and addressed by the
Multi Control instrument, the push-buttons of the Multi Control instrument will be used
to operate the Multi XL. It functions just like a TV remote control, but this instrument
needs to have a cable to transmit the signal.
Most functions explained in this manual can be remote controlled using the pushbuttons of remote instrument and looking at the Multi XL display, or by setting values
direct on the Multi Control instrument.
Note! This manual describes the operation of the Multi XL by the Multi Control
Instrument.

DEPTH functions
6.1
Depth general information
Alarm on = minute sign [ ´ ] displayed above the last depth digit in
the sub-function.
Alarm off = no minute sign [ ´ ] displayed.
The alarms will be triggered, if the actual depth becomes less
(shallow alarm), or more (depth alarm), than the set depth value.
The alarm is audible (signal) and visual (main and sub-function
flashes).
When a triggered alarm has been silenced, it will only be triggered
again if the selected depth value differs by +/-2m (6 ft).
If a different page than DEPTH is shown when the alarm is
triggered, the set alarm function will automatically be shown
flashing, until you silence or turn off the alarm. The instrument will
then automatically return to the previous page.
Note! Loss of signal. If there are no depth echoes for 3 seconds,
the display indicates 3 dotted lines [ --- ] until a new echo is
received.
6.2
DEPTH main-function
Depth from the water surface or the keel depending on setting.
Unit available in meters [m], feet [FT] or fathoms [FA]. (See setup
C21).
6.3
DEPTH sub-functions
6.3.1
Shallow alarm [SHA]
Depth at which point audible and visual alarms will be triggered, if
the actual depth becomes less than the set value. (See chapter
6.4).
6.3.2
Depth alarm [DEA]
The depth at which point audible and visual alarms will be triggered,
if the actual depth becomes more than the set value. (See chapter

When the anchor alarm is set, the instrument will first suggest a
value for the shallow [SHA] alarm (actual depth minus 1,5 m / 5 FT)
then a value for the depth [DEA] alarm (actual value plus 1.5 m / 5
FT).
You can either lock the suggested values or set your own values.
The logic is that when you are at anchor, the alarm will warn you if
the boat is drifting towards deeper or shallower water. (See

7.3
Steer reference (Pilot)
The sub-function (Pilot) is intended to be used together with the optional analogue
instrument steer pilot to assist the helmsman to keep the desired heading.
The powerful combination of the Multi Control instrument together with the
analogue steer pilot actually offers you 6 functions.
Compass steering: (MEM)
1. Compass steering, using the 1 memory.
2. Headers and lifters, using the 2 memories and trim button. (See TAC function in
Multi Control )
Wind steering: (AWA)
3. Close hauled indicator, ex. 35°
4. Down wind indicator, ex. 175°
Waypoint steering:
5. Bearing To waypoint (BTW)
6. Course To Steer (CTS), including set and drift
When a steer reference has been selected the analogue steer pilot instrument is
immediately activated. It starts to indicate the difference between desired and actual
heading or angle. The logic is to keep the steer pilot instrument needle straight up
pointing at zero (0) to stay on the set heading.
From analogue steer pilot instrument version 2.0, (MEM) and (BTW) is functioning with
COG (if navigator connected) even if a compass is not installed . The analogue read
out will start at speed above 4KTS and stop below 2 KTS (valid for Server from ver 4.1).
If you do not have the analogue steer pilot instrument, you can still use the function, if
you display the selected steer reference heading (STR) in the sub-function and
compare it with the actual compass heading in the main-function.
A NX2 autopilot can not be activated from the steer reference function. But when the
NX2 autopilot has been activated in compass or wind mode it is possible to alter the
autopilots heading from the (MEM) and (AWA) functions.
The last used steer reference function will be stored in memory and automatically
activated at power on.

Steer reference (AWA)
This function requires the NX2 or NMEA wind transducer.
The function is semi automatic, i.e. when activated, present wind
angle is copied to memory. You can also change the value manually.
The function displays the deviation from a set wind angle value and can be used as a
”close hauled” tack indicator, or show an enlarged ”picture” of the running angle.

MULTI XL
The underlining sign ( _ ) = starboard side. The minus sign ( - ) = port side.
To select value, press MINUS, PLUS and PAGE as required.
To store the value, press SET.
When the steer reference function (AWA) is used together with the analogue steer pilot
instrument, you can display an enlarged ”picture” of the tacking or run angle..
Use the analogue steer pilot as a ”close hauled” instrument.
Example: You have selected 35° starboard side (35° |- STR) as your tacking angle.
When the needle on the analogue steer pilot instrument points straight up to zero (0),
you steer at the selected 35° wind angle.
You can of course also use the (AWA) function when running down wind, to keep a
selected value for the run angle and/or to warn for a gibe.
Example: You have selected 160° port side (160° -| STR) as your running angle. When
the needle on the analogue steer pilot instrument points to 15° port side you are at
145°. When the needle is at zero (0) you are at 160°. When the needle points 15°
starboard you are at 175°.
At night, when you can not see the wind shifts, the use of the (AWA) function together
with the analogue steer pilot is a very helpful.
This is a dynamite function that allows you to ”expand” the wind angles!!!
When a NX2 Autopilot is activated in wind mode, the (AWA) function on the Multi
Control instrument can be used to perform an automatic tack.
The minus sign ( - ) in front of the wind angle value = port side.
The underlining sign ( _ ) in front of the wind angle value = starboard side.
Simply change the value of the digit in front of the wind angle, and the NX2 Autopilot
will gibe to the opposite tack.

11.6 Special NMEA sentences
The Nexus Server can read two special NMEA sentences which can be sent from a
PC. One contains TBS (target boat speed), the other CAD (customised angle data )
and CFD (customised fixpoint data ). These 3 data are re-transmitted on the Nexus
Network and can be displayed as a sub-function on the Multi XL instrument.
Note! [TBS] and [CAD] may also be displayed as main functions.

12 Maintenance and fault finding
12.1 Maintenance
•
•
•
•
•
To clean the instrument, use only mild soap solution and rinse with water.
Do not use detergents or high pressure washing equipment.
At least once a year, check all your connections and apply additional silicon paste at
each connection point.
Always use the instrument cover for protection, when not in use.
Storing transducers and instruments when not in use for longer periods: It is
advisable to remove the instruments and transducers, and store them inside the
boat or at home in room temperature, if possible.
12.2 Fault finding
12.2.1 General
Before you contact your Nexus dealer, and to assist your dealer to give you a better
service, please check the following points and make a list of:
•
•
All connected instruments and transducers, including their version numbers.
Nexus Network ID numbers for each instrument (displayed at power up).
In most cases, the reason for faults in electronic equipment is the installation or poor
connections. Therefore, always first check that:
•
•
•
•
•
•
•
•
•
Installation and connection is made per instructions for instrument and transducers.
Screw terminals are carefully tightened.
No corrosion on any connection points.
No loose ends in the wires causing short cuts to adjacent wires.
Cables for damage, that no cables are squeezed or worn.
Battery voltage is sufficient, should be at least 10V DC.
The fuse is not blown and the circuit-breaker has not opened.
The fuse is of the right type.
Two instruments do not have the same ID number.
12.2.2 What you should know about digital depth sounders
The principle of a depth sounder is that you measure the time it takes for a short
acoustic signal to go from the transducer to the sea bottom and back again to the
transducer.
The echo changes due to bottom character, heavy layers of salt and temperature
layers, irregular bottom vegetation, fish etc. Thanks to advanced high-tech treatment of
the signal, these variations will normally not influence the depth measurement.
You can in some circumstances get transitory disturbances. In the list below you will
find some explanations of disturbances to the measurement of depth and how it is
shown on the instrument display.
43
MULTI XL
In general, when a boat is moored in a harbour with other boats around, there can be
disturbances from signals from other depth transducers, chains or other mooring
equipment, which will result in wrong depth readings.

13.2 Nexus Network introduction and user policy
Introduction:
The Nexus data bus is a multi talker multi receiver data bus specially designed for
marine navigation applications. It utilises the RS485 standard with up to 32 senders
and/or receivers to form a Local Area Network. Data is transmitted synchronously with 1
start-bit, 8-data-bits, 1 parity-bit, two stop-bits in 9600 baud.
User policy:
The Nexus data bus is open for new users and applications without a licence or a
licence fee. The data bus is, however, the property of the manufacturer, which means
the specification must be followed in order to protect the manufacturer’s commitments
to the Nexus data bus performance and safety.
For most PC-applications, the full duplex interface, will be a very useful tool for
monitoring real time data, to edit and store waypoints to PC-file or to Server. The
interface is supplied with a cable for connection from PC to the Server or NX2
instruments. A 9-pole D-sub connector is connected to the RS232 port on the PC.
