INTRODUCTION
Welcome aboard the Nexus Network!
Thank you for choosing Nexus 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 Nexus transducers.
The Nexus Network is designed with the industry standard RS 485
databus, which allows you to connect up to 32 Nexus 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 4pole 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.
Nexus 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 four 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.
These Nexus instruments carry a two year warranty, which gives
you as our customer, confidence to trust Nexus and our
commitment to quality.
To get the most out of your new Nexus product, please read
through this manual carefully before you start your installation.

Installation
•
The installation includes 6 major steps:
1.
Read the installation and 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 50 mm (2")
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 Nexus 8
m (26 ft) extension cable ( Art. No.21266-8 ), or use left over
Nexus cable from other installations. The same 4-pole Nexus
cable is used for all connections.
If you are doubtful about the installation, obtain the services of an
experienced technician.
10
www.busse-yachtshop.de | info@busse-yachtshop.de
INSTALLATION
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 baseplate 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
un-marked cable end, since a marked cable is easier to identify.
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!
11
www.busse-yachtshop.de | info@busse-yachtshop.de
INSTALLATION
2.3
Location of the instrument
The instrument is designed to be front mounted above or below
deck. It should be mounted on a flat and smooth surface. This
condition must be followed to ensure the gasket seals correctly
against the mounting surface. Mount the instrument so that it:
•
•
•
•
can be read by the helmsman / navigator,
is satisfactorily protected from outer damage,
is at least 500 mm (20“) from radio receiving equipment,
has sufficient clearance from behind, for the instrument
housing and cables. The instrument can be mounted right next
to a magnetic compass.
Note: On the reverse side, above the connection pins, the
instrument has a small ventilation hole to avoid moisture gathering
inside the instrument. The hole is protected by a ventilation
membrane that allows air but not water to pass.
The instrument can be mounted on a mast bracket, provided
enough silicon paste is applied to protect the connector.
2.4
Installing the instrument
Place the adhesive drill template on the desired location for the
instrument. Drill the 4 screw holes using a 2,8 mm (0,11") drill.
Use a 50 mm (2") hole saw to machine the clearance hole for the
instrument connection socket. Remove the template.
Note: Never drill through the instruments 4 mounting holes
as the gaskets may be damaged and thus cause leakage. The
warranty is not valid for damage caused by drilling through
the mounting holes.
•
Run the Nexus Network cable from the Server to the
instrument.
•
Cut the Nexus Network cable to length. Peel off about 35 mm
(1,4") of the cable insulation. Remove about 6 mm (1/4") from
the 3 isolated wires (the 4:th wire is a 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.
12

INSTALLATION
Silicon paste
Silicon paste
•
Apply silicon paste to the instrument connection pins at the
back of the instrument. Press the jack plug onto the instrument
pins. Press down the cable in the cable leads. Mount the
connection back cover with the 1 screw.
•
Mount the instrument in the pre-drilled position.
Note! Use all 4 screws, and tighten the screws (in cross
pattern) so the gasket will be evenly compressed to 1/3 of its
original thickness.
Very important for a correct sealing to avoid leakage!
•
Press on the 4 rubber caps to seal and hide the mounting
screws.
Your instrument installation is done!

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
9 (IN).
Connect NMEA return signal from the NMEA instrument to Server
pin 10 (RETURN). (For list of NMEA receive sentences, see
12.6.3).
16
www.busse-yachtshop.de | info@busse-yachtshop.de
INSTALLATION
Note a: The Server allows only one NMEA instrument connected
to the input pins 9 and 10.
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 Nexus data bus.
Note c: If the NMEA instrument has only one output cable, put a
”bridge” cable on the Server between pins 10 (RETURN) and 12
(RETURN).(See chapter 12.6 , C75)
2.9
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 11
(OUT). Connect NMEA return signal from NMEA instrument to
Server pin 12 (RETURN). (For list of NMEA transmit sentences,
see 12.61.)
2.10
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.

3.1
First start
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 and
the Nexus Network ID number.
At first power on after installation, you will be asked to press KEY
(PrESkey). This will give the instrument a logical ID number on the
Nexus Network.
To initialise the instrument, press KEY on all installed digital
instruments, one at the time.
Note: Always wait for the text ”Init OK”
to be displayed, before you press KEY
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 KEY 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 2.0 and
the given logical ID number is 16.
3.2
Re-initializing 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 DOWN and UP together
during the power up sequence 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 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.

Depth functions
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 audiable (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.
Loss of signal. If there are no depth echoes for 3 seconds, the
display indicates 3 dotted lines ( --- ) until a new echo is received.
7.1

reception.
This function is only valid if a Nexus GPS receiver is connected to
the Nexus Network.
8.3
Steer reference (Pilot)
The sub-function (Pilot) is intended to be used together with the
optional analogue instrument steer pilot (Art. No. 20550-2) 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
9.1)
Wind steering: (AWA)
3. Close hauled indicator, ex. 35°
4. Down wind indicator, ex. 175°
Waypoint steering:
36
www.busse-yachtshop.de | info@busse-yachtshop.de
NAVIGATION FUNCTIONS
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 at
speed above 4KTS and stop below 2 KTS.
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 Nexus autopilot can not be activated from the steer reference
function. But when the Nexus 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. (Available Server version
2.6)

NAVIGATION FUNCTIONS
8.3.4
Steer reference (CTS)
This function requires log transducer, Nexus or NMEA compass
transducer , Nexus GPS or NMEA navigator.
When selected the function displays (CTS) and the analogue steer
pilot instrument displays the difference between the compass
heading and the bearing to waypoint (CTS) including set and drift.
The function can only be displayed if the connected navigator is
navigating towards a waypoint.
Since the displayed value it is controlled by the navigator, the
value can not be altered.
The function is compensated for set and drift, by using the
parameters compass heading, boat speed through the water,
course and speed over ground (COG/SOG) and bearing to
waypoint (BTW).
Select sub-function (Pilot), press KEY.
The text (OFF) or the last selected steer reference function
flashes.
To select steer reference (CTS), press UP.
To store the function, press KEY. MEM WP is lit on the display.
The sub-function (STR) automatically displays the stored (CTS)
value.
The text (CTS) and (STR) is alternating.
The function is invaluable when you want to sail the shortest
distance to a waypoint.
8.3.5
Steer reference (AWA)
This function requires the Nexus 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.
Select sub-function (Pilot), press KEY.
The text (OFF) or the last selected steer reference function
flashes.
To select steer reference (AWA), press UP.
To store the function, press KEY. WIND is shown on the display.
The sub-function (STR) automatically displays the stored (AWA)
value.
The text (AWA) and (STR) is alternating.
If you want to change the steer reference value, press KEY.
The first digit flashes.
The underlining sign ( _ ) = starboard side. The minus sign ( - ) =
port side.
39
www.busse-yachtshop.de | info@busse-yachtshop.de
NAVIGATION FUNCTIONS
To select value, press DOWN, UP and MODE as required.
To store the value, press KEY.
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. Put simply, you ”expand” the
wind 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 gybe.
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 Nexus 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 Nexus Autopilot will gibe to the opposite tack.
8.4
Store and edit a waypoint (Edit WP)
The Server contains a memory that stores up to 99 waypoints in a
non-volatile memory.
Waypoint number 99 can be used as an ordinary waypoint, but if
the MOB button is activated, this waypoint will be over-written by
the MOB position.

NAVIGATION FUNCTIONS
Note: Which instrument is navigating? By the term
navigating, we mean the active instrument in which the
waypoint memory is used for navigation to calculate the
navigation data, ie BTW, DTW etc. There can only be one
instrument on the Nexus Network which is keeping the
waypoints in memory, but the waypoints can be reached from
all instruments.
•
•
•
If a portable Nexus GPS is connected, the Server takes over
the navigation.
If a Nexus GPS Navigator instrument (art no 21032) and
Antenna (art no 21000) is connected, the Nexus GPS
Navigator instrument will take over the navigation when in
Master mode. Through the configuration of this instrument, it
can also be set to be a Nexus or NMEA repeater.

The Server contains a memory for 1 sailplan that can store up to
24 waypoints.
Each part of the sailplan is called a leg. A leg consists of 1 go
from (Go FROM) waypoint and 1 go to next (Goto NXT) waypoint.
The sailplan is stored in a volatile memory, which means that the
sailplan will be lost when the electrical power is cut. However the
individual waypoints (01-99) remain in the (Edit WP) memory.
42
www.busse-yachtshop.de | info@busse-yachtshop.de
NAVIGATION FUNCTIONS
The procedure to create a sailplan is:
• Select the sub-function (Goto WP).
• Decide if you want to (Go FROM) present position (00) or from
any another waypoint.
• Select a waypoint to (Goto NXT) in the first leg.
• Select waypoint for leg 2, leg 3 etc. up to the maximum 24
waypoints/legs.
• At the very moment, when the KEY is pressed in mode (Goto
NXT), the Server will start the navigation and all navigation
calculations will be displayed in the instrument.
Position to go from (Go FROM) is displayed as waypoint (00)
when you navigate from your present position.
If you want to start navigation from any other waypoint (01 - 99),
you can select that other waypoint number as your (Go FROM)
position. The (Go FROM) position is mainly used to define your
track line, to calculate XTE etc.
When the Nexus Network is set to be a repeater for an external
NMEA navigator which is performing the navigation, you can
display the waypoint in the (Goto WP) function, but you can not
edit a waypoint other than in the NMEA navigator.
8.5.1

waypoint must first be stored in memory (Edit WP), (see 8.4.2).
Select the sub-function (Goto WP).
To create a sailplan, press KEY.
The function go to next (Goto NXT) is displayed and the small text
(WP) flashes.
To unlock the waypoint, press KEY.
The first digit of the last ”active” waypoint flashes.
To select a waypoint, press DOWN, UP and MODE as required.
To store the value, press KEY.
Note: At this very moment, when the KEY is pressed, the
Server will start navigation calculation based on your stored
waypoint and the navigation data will be available on the
Nexus Network.
Bearing (123°) and distance (12.34) NM for the first leg (*01), from
current position (00) to the waypoint (01) is displayed on the
instrument.
Note: Always check with your sea chart that the bearing and
distance is correct before you continue with the next leg.
If there is a difference, check that the co-ordinates in function
(Edit WP) are correct.

The audible and visual arrival alarm is triggered. (See 8.6).
The next waypoint in the sailplan (Goto NXT) will be activated
as the new (Goto WP).
The arrival waypoint is changed into the (Go From) waypoint.
The previous (Go From) waypoint is cancelled from the
sailplan.
When you have arrived at your last waypoint in the sailplan, the
last waypoint will remain in memory (displayed as (Goto) and no.)
and the sailplan will remain ”active” (still calculating navigation
data), until the power is cut.
If you want to cancel the last waypoint from the sailplan memory
and thereby stop the navigation, press DOWN and UP together,
when (Goto) and no. is displayed.
After that, (Goto WP) will be displayed, which confirms the
sailplan is empty.
8.5.2
Go to waypoint, from other than your present position
Position to go from (Go FROM) is displayed as waypoint (00)
when you navigate from your present position.
If you want to start navigation from any other waypoint (01 - 99),
you can select that other waypoint number as your (Go FROM)
position.

The cross track error (XTE) function will be calculated with respect
to this new bearing and not as if the starting position was the
present position (00).
8.5.3
Cancel a leg in the sailplan
If the sub-function displays (Goto WP), it confirms the sailplan is
empty, that means that no waypoints are stored in it.
If the sub-function displays (Goto) and a number, example (Goto
3), it confirms the sailplan is ”active” (at least one waypoint is
stored in it), and that the Server is actually calculating navigation
data towards the displayed ”active” waypoint.
Select sub-function (Goto 3), press KEY.
To select the leg you want to cancel, press DOWN or UP.
To cancel the selected waypoint, press DOWN and UP together.
The next leg in the sail plan is displayed.
To exit from the function, press MODE.
8.5.4
Insert a waypoint in the sailplan
The function insert (In-SErt) allows you to rearrange the sailplan if
you want to insert or cancel a waypoint.
Example: Enter any 4 waypoints (Edit WP) , (see 8.4.2), and store
them in spailplan (Goto WP), (see 8.5.1), in the following leg
order:
Leg (*1) Go FROM (00) Goto NXT (01)
Leg (*2) Go FROM (01) Goto NXT (02)
Leg (*3) Go FROM (02) Goto NXT (03)
Leg (*4) Go FROM (03) Goto NXT (04)
Let us say that you change your plans and would like to go from
waypoint (02) direct to waypoint (04), that is to insert waypoint
(04) before leg (*3).
Since you are still in the dock and have not started your trip, the
display will indicate (Goto 1), based on above sailplan.

The text (In-SErt) will be displayed with the previous Goto NXT
waypoint flashing.
To select waypoint number (04), press MODE then UP 1 time.
To store the inserted waypoint (04), press KEY.
Bearing and distance from the previous waypoint (02) to the
inserted waypoint (04) will be displayed as the new leg *(3).
To exit from the function, press MODE.
The new sail plan will look like this:
Leg (*1) Go FROM (00) Goto NXT (01)
Leg (*2) Go FROM (01) Goto NXT (02)
Leg (*3) Go FROM (02) Goto NXT (04)
Leg (*4) Go FROM (04) Goto NXT (03)
Leg (*5) Go FROM (03) Goto NXT (04)
The last inserted waypoint will move down all the following
waypoints one step in the sailplan. If the sailplan is already
contains 24 waypoints (full), and you add or insert a new
waypoint, the 24:th waypoint will be automatically cancelled from
the sailplan.
8.6
Arrival alarm
If the function (Goto WP) has been activated, the audible and
visual arrival alarm is triggered automatically, when the boat
arrives within a selected radius from the (Goto WP) waypoint.
Factory setting radius value is 0.10 nautical mile. (See 12.3.12,
C41).
When the audible alarm is triggered (beeps 3 times), the text
(ArriVAL) flashes 3 times on all connected Multi Control
instruments. After the arrival alarm the instrument will revert to the
previous displayed function.

Wind functions
9.1
WIND Main-function
Apparent wind angle (AWA), true wind angle (TWA) 000° - 359°,
apparent wind speed (AWS) or true wind speed (TWS):
The main-function WIND, allows you to display wind angle or wind
speed, true or apparent. The wind angle is indicated by a symbol
to the right of the wind angle value:
= Wind from port side.
= Wind from starboard side.
The type of wind true or apparent, is indicated by a letter:
= Apparent wind .
= True wind.
The selection of apparent (AWA) or true (TWA) wind angle in the
main function also controls what is displayed on the optional
analogue wind instrument (art. no 20550-1).
When the instrument is delivered, the factory setting for the main
function is apparent wind angle (AWA). (See 12.5, C51 and C63).
9.2
9.2.1
WIND Sub-functions
APPARENT WIND SPEED (AWS)
Units displayed in m/s (m/s), knots (KTS) or Beaufort (BF), (see
12.5, C52). The function alternates between (AWS) and the
selected (units).
9.2.2 TRUE WIND ANGLE (TWA)
This function requires a log transducer. The complimenting function
to what is displayed in the main function is displayed.
If the main function is set to display apparent wind angle (AWA),
the true wind angle (TWA) will be displayed here.
If the main-function is set to display true wind angle (TWA), the
apparent wind angle (AWA) will be displayed here.
If the main-function is set to display apparent wind speed (AWS),
apparent wind angle (AWA) will be displayed here.
If the main-function is set to display true wind speed (TWS), true
wind angle (TWA) will be displayed here.

then select MID or (MAX). Damping is set separately for each
instrument.
9.2.3
TRUE WIND SPEED TWS
This function requires a log transducer. Displayed in m/s (m/s),
knots (KTS) or Beaufort (BF). (See 12.5, C52).The text alternates
between (TWS) and the selected (unit)
9.2.4
GEOGRAPHIC WIND DIRECTION
This function requires a compass transducer. Displays the
direction in 000° to 359° and the each cardinal point abbreviation
as shown:
000.0° = N
022.5° = NNE
045.0° = NE
067.5° = ENE
090.0° = E
112.5° = ESE
135.0° = SE
157.5° = SSE
180.0° = S
202.5° = SSW
225.0° = SW
247.5° = WSW
270.0° = W
292.5° = WNW
315.0° = NW
337.5° = NNW
If magnetic heading is selected, geographic wind direction will also
be magnetic direction. (See 12.4, C32 and C47)

WIND FUNCTIONS
9.2.5
VELOCITY MADE GOOD (VMG)
Displays speed into the wind or speed running with the wind in
(KTS), (Km) or (Mh), (see 12.1.2, C11). See drawing.
The text alternates between (VMG) and the selected (unit).
9.2.6
TACTICAL FUNCTION (TAC)
Displays heading memory, one for starboard and one for port tack.
(For function explanation, see 9.3).
9.2.7
WAYPOINT CLOSURE VELOCITY (WCV)
Displays the speed over ground towards the waypoint in (KTS),
(Km) or (Mh), (see 12.1.2, C11).
The text alternates between (WCV) and the selected (unit).
9.2.8
SET and DRIFT
Direction of current (SET) and speed of current (DRF).
Alternating function. To stop alternating, press KEY.
To restart alternating, press KEY again.
9.2.9
ROLL (Roll)
The heeling angle of the boat.
= heeling to starboard side.
= heeling to port side.
The Server will compensate the wind angle and the wind speed
errors due to heeling.
The compensation is already implemented in the Nexus Network,
but a transducer to indicate roll is not yet available.
9.3
Tactical function
This function requires a compass transducer and displays course
memory. One for starboard and one for port tack.
To fully use the tactical function it is recommended to install the
optional trim button (Art. No. 19763) and analogue steer pilot
instrument (Art. No 20550-2). The trim button is usually installed
close to the steering position. Many prefer to install one trim
button on each side of the boat, that is one for each tack. (For
installation of trim button, see 2.4.2). Your apparent tack angle is
assumed to be constant, in that your magnetic heading will be

WIND FUNCTIONS
changed compared to the wind, that is you will be changing your
heading due to the wind shifts.
The tactical function will give you a fast and exact information
about any wind shift compared to the magnetic heading.
Select sub-function (TAC).
When you have maximum ”lift”, press KEY (or the trim button) to
store the value. When the wind ”heads” more than 5-10* it is time
to tack.
Follow the same procedure on the new leg. The reference value
for the selected tack, will be changed every time you press KEY
(or the trim button). When you tack, the reference value of the last
leg will automatically be displayed.
If the optional analogue steer pilot instrument connected, select
sub-function pilot (MEM), as steer reference (See 8.3).
The deviation from selected course will be displayed on the
analogue steer pilot instrument.
If you do not have the optional trim button or analogue steer pilot
connected, we suggest you move the sub-function (TAC) to the
NAVIGATE page. Now you can display both the heading and the
tactical reference (TAC) at the same time.
Remember to turn off the off course alarm. To turn off the off
course alarm, set C31 to (00*), (See 12.3.2, C31).

MAN OVER BOARD FUNCTION
10
Man over board (MOB) function
This function will guide you back to the position where the man
over board (MOB) button was pressed.
This function requires either a navigator (a Nexus GPS or NMEA
navigator can be used as long as the Server is set to perform the
navigation, see 12.6, C75), or a speed and compass transducer as
well as a man over board (MOB) button. (See 2.4.1).
If only a compass and a speed transducer is connected, dead
reckoning (MOB) will be displayed on both the Multi Control and
the SPEED Log instruments. Dead reckoning (MOB) is also a very
useful information, since a person in the water will drift almost as
fast as the boat.
If a navigator, a compass and a log transducer is connected, dead
reckoning (MOB) will be performed and displayed in the SPEED
Log instrument. At the same time the Multi Control instrument will
display (MOB) relative position stored in memory when the (MOB)
button was activated. A position in latitude and longitude is more
important for the sea rescue service.
The (MOB) position is automatically stored in waypoint number
99, and over writes any earlier stored position.
To activate the MOB function, press the (MOB) button.
A fixed alarm signal will sound briefly to alert the crew. The text
(MOB) flashes.
Off course error will be displayed in the main-function.
= steer to starboard.
= steer to port.
Distance to the MOB position will be displayed in the sub-function.
All you have to do is to keep calm and steer the boat in the
indicated direction and distance to pick up your wet crew member.
To reset the (MOB) function, press DOWN and UP together.
The earlier calculated course (CMG) and the distance made good
(DMG) is not affected by the (MOB) function.
If a Nexus GPS and the analogue steer pilot instrument is
connected the analogue instrument will indicate (MOB) course
difference with priority to GPS position over dead reckoning
position.
Note: It is wise to practice this manoeuvre with the crew.
Everyone in the crew should be aware of the (MOB) routine. When
you practice, it can be thoughtful to use a fender instead of a crew
member!!!

www.busse-yachtshop.de | info@busse-yachtshop.de
CALIBRATION
If the deviation is not corrected, an error message will be
displayed.
To verify the automatic compass deviation, perform an automatic
compass check (Auto CHK), (see 12.4.2).
Note: You will get the best result in calm water with a smooth turn
on the steering wheel independently of how the circle is performed.
When activated, you can stop the automatic compass deviation at
any time with a press on DOWN and UP together.
12.4.2
Automatic compass deviation check (Auto CHK)
(Auto CHK) is done by driving the boat in a circle up to 1 ¼ turn,
after (Auto DEV) is performed. The result will be compared with
(Auto DEV). If the deviation is less than 1,5*, the average value
from the comparison between (Auto DEV) and (Auto CHK) will be
stored.
If the check is OK, (Auto CHK) will be displayed.
If not an error message will be displayed.
Select automatic compass check (Auto CHK), press KEY and
repeat the same circle manoeuvre as described in the (Auto DEV)
routine.
Note: As soon as you place any kind of ferrous items close to the
compass, the (Auto DEV) / (Auto CHK) routines should be
repeated. So if you have packed your boat for the vacation, think
about where you place ferrous items in relation to the compass
transducer.

Change NMEA sentences OUT from Server
Before you change any of the factory set NMEA sentences, check
what NMEA sentences can be received by your NMEA navigator.
Select the slot number for the sentence to be changed, then press
KEY.
To select the sentence, press DOWN or UP until found.
To lock the selected sentence, press KEY.
One of the advantages with the Nexus Network is the very fast
transmission speed of data compared to the relatively slow NMEA
standard (about 10 times faster). Therefore we recommend that
you use Nexus instruments and transducers for better accuracy.
It takes two seconds to transmit all 16 NMEA sentences.
To double the transmission speed, select a NMEA sentence 2
times with 7 slots apart, that is the slots should be as far away
from each other as possible.
In a similar way, you can select the a sentence 4 times to make it
4 times faster.
Example: If you want to transmit the Nexus compass heading via
NMEA, to for example an autopilot, select (HDM) for every odd
slot number, C79, C81, C83 ... C93, that is 8 times which makes
the speed 4 times / second. This leaves the other 8 slots with even
numbers, C78, C80, C82 ... C94 free to use for other NMEA
sentences.

Receive NMEA sentences IN to Server
There are 5 different main types of NMEA sentences:
1) Position related data: Position, SOG/COG, time, and a limited
amount of satellite status if a GPS is connected. The information
is read if no other Nexus GPS is connected. If a Nexus GPS is
connected, it will take over the navigation.
2) Navigation data: (BTW), (DTW), (BOD), (XTE), (SET) and
(DRIFT). This information is read only if C75 NAV is set to (ON).
The Server will automatically send data to the Nexus Network.
E.g.: (DRIFT), (WCV), (TTG) and (CTS).
3) Waypoint data: Is received from (WPL) data if (C73 WPR) is
set to on (ON). Nexus Server version 1.7 and higher can receive
(NMEA WP) and re-transmit to an active Nexus navigator through
the Nexus Network.
4) Compass heading is read only if (C76 CMP) is set to (ON).
Heading is either (HDT) (priority) or (HDM). Magnetic variation
(from Nexus Network) is added to (HDM) but not to (HDT).
5) Relative wind angle and wind speed is read from (VWR) data,
only if (C77 WND) is set to (ON). True wind angle and wind speed
is calculated by Nexus, when the boat speed (the speed of the
water) is known.

Example I: Position is read in priority order: RMC, GGA, RMA and
GLL.
Example II: BTW/DTW is priority first with: RMB, BWC and BWR.
The transmission ID (the first two letters after “$”) is ignored by the
Server. Present position is read, after that possible latitude and
longitude correction is added (C39 and C40) before the position is
sent over the Nexus Network to all instruments
12.8
Special NMEA sentences
The Server can read 2 special NMEA sentences which can be
send from a PC. One contains TBS (target boat speed), the other
CAD (customised angle data ) and CFD (customised fixpoint data
). These 3 data are retransmitted on the Nexus Network and can
be displayed as a sub-function on the Multi Control instrument.
To get the sub-function TBS, select main function SPEED and the
”empty” sub-function.Then press MODE and KEY together
followed by UP and DOWN thogether.
To get the sub-function CAD, select main function NAVIGATE and
the ”empty” sub-function.Then press MODE and KEY together
followed by UP and DOWN thogether.
To get the sub-function CFD, select main function WIND and the
”empty” sub-function.Then press MODE and KEY together
followed by UP and DOWN thogether.
Example of special NMEA-sentence:

MAINTENANCE AND FAULT FINDING
13.2.2
Fault - action
1. Speed and distance functions: No reading ( --- )
- C13 (COG) should be OFF, if no navigator is connected.
If you have a voltmeter available, you can check the condition of
the transducer. When measuring with voltmeter check that
everything is connected, that the power is on and make sure the
paddle wheel is rotating.
At the Server right hand side, measure between pin 2 and 4.
When not rotating, the value should be fixed at either about 0 or
5V DC. When rotating very slowly, by hand, the value should flip
between 0 and 5V DC. When rotating faster, the value should
average around 2.5V DC.
Irregular values: Check the speed damping (SEA), (see 6.2.7).
2. Compass: No reading ( --- )
− C76 should be OFF, if no NMEA compass is connected.
− Make sure the (Auto DEV) routine is done correctly, (see
12.4.1)
− Make sure the transducer is not mounted upside down.
− The transducer cable should face down.
− Make sure transducer is aligned correctly, (see 12.3.7, C36).
With a voltmeter, on the Server right hand side, measure between
pin 10 and 12, and between 11 and 12.
When the compass is rotated one turn (360*), the average value
should vary between 0.8V DC and 4.2V DC twice during the turn.
Irregular values: Check the compass damping (SEA), (see
8.2.3).
Make sure there are no ferrous items close to the transducer.
3. Wind: No reading ( --- )
− C77 should be OFF, if no NMEA wind is connected.
− If inaccurate wind data is received, check the connections
(separate through deck connection or below decks connection),
are properly made.
− Measure with a voltmeter, at the Server right hand side pins 14
and 16, and between pins 15 and 16.
− If the voltmeter shows 1.5 to 4V DC (minimum wind speed 3
m/s) at both measuring points, the transducer and the
connections are OK,
− If the voltmeter shows 0 or 5 V DC at both measuring points,
the transducer or the connections are defect. Contact you
Nexus dealer with this information.
− Make sure the transducer is aligned correctly, (see 12.5.6,
C54).

MAINTENANCE AND FAULT FINDING
4. Navigation:
− Which instrument is navigating? (See 12.6, C75)
− C75 (OFF) = The Server is navigating.
− C75 (ON) = The NMEA navigator is navigating.
− If problem with NMEA IN to Server, (see 12.7 and 12.6.4).
− If problem with NMEA OUT from Server, (see 12.6.7 and
12.6.5).
5. 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
bottom and back again to the transducer.
The echo changes due to bottom character, heavy layers of salt
and temperature, irregular bottom vegetation, fish etc. Thanks to
an advanced signal treatment, these variations will normally not
influence the depth measurement.
You can in some circumstances get transitory disturbances.
Below are listed some explanations for disturbances to the
measurement of depth and how it is expressed on the instrument
display.
1. There is no depth reading on the display. Only ( --- ) is
displayed:
If there are no depth echoes for 3 seconds, the display indicates 3
dotted lines ( --- ) until a new echo is received.
• In deep water outside the range of the transducer, or the
combination of deep water and soft bottom which makes it
difficult to reflect the signal.
• When the boat is heeling heavily, for example when sailing.
• In a propeller stream, where air bubbles are created. Example
when powering astern or when following close behind a power
boat.
• Check the connection at the amplifier box. Make sure the cable
is correct between, instrument and transducer, as marked on
the box.
• Internal mount with poor signal penetration due to a too thick
hull, (maximum thickness recommended is 20 - 30 mm) or air
between transducer and hull.
72
www.busse-yachtshop.de | info@busse-yachtshop.de
MAINTENANCE AND FAULT FINDING
2. Unstable or erratic readings. Can happen in the following cases:
• When going over shoal water, with uneven and high bottom
vege-tation.
• In heavy layers of salt or noticeable ranges of water
temperatures.
• In heavily agitated water containing particles of sand or some
other contamination.
The bottom of the transducer may be painted with anti fouling for
protection against weed growth. It is recommended the transducer
is cleaned at regular intervals depending on what kind of waters
you boat in.
Weed on the transducer can cause either no reading or unstable
readings.
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.

Nexus databus 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 the 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 (Art. No.
21248), will be a very useful tool for monitoring real time data, to
edit and store waypoints to PC-file or to Server and/or to the
Nexus GPS. The interface is supplied with a cable for connection
from PC to the Server or Nexus instruments and/or the Nexus
GPS. A 9-pole D-sub connector is connected to the RS232 port
on the PC.
