MULTI XL
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 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 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!

2 Installation
• The installation includes 6 major steps:
1. Read the operation manual.
2. Plan where to install the transducers and instruments.
3. Run the cables.
4. Install the transducers and instruments.
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").
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.
12
MULTI XL
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
Silicon paste
• 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.
13
MULTI XL
• 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.
Note! The two nuts must just be tighten by hand
• 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.
• Slide in the cables into the cable slot on the outer protection cover
• Note, do not cover the slot totally, a hole is needed for draining.
• Put on the outer protection cover
• Screw the two nuts from the back
2.1.1 Installing instrument to the Server
All NX2 instruments are connected directly to the Nexus Network in a daisy chain. They
all use the same colour coded 4-pole jack plugs.

MULTI XL
3 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.
Magnet
Proceed with next instrument, one at the time.
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.

4 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 push-
buttons 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.
