REMOTE CONTROL
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 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.
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!

Introduction
1.1
Welcome aboard!
Thank you for choosing a Nexus Remote Control instrument. Through this manual we would like
to help you to install and operate your Nexus product. We are convinced that you will appreciate
the useful functions weather you are a cruiser or a racer. To get the most out of your Nexus
product, please read through this manual carefully before you start your installation. If you see us
at a show, stop by and say hello.
Good luck and happy boating!
1.2
Capabilities
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 data bus cable carries power and data to the instruments,
which are repeaters of the information sent from the Server.
Your Remote Control instrument can be connected directly to a Nexus instrument on the Nexus
Network, or to the Nexus Server, and if so you do not have to re-calibrate the transducers or your
current Nexus Network setup.
The Remote Control instrument is more than just a remote control:
•
•
•
•
•
•
•
•
•
•
It is a Nexus Multi function instrument in itself, displaying all functions in your Network.
It can remote control all, or selected Nexus instruments in your Network.
It can be used at the chart table as the waypoint and rout editor in your Network
It can be an integrated control unit for the Nexus Autopilot.
It offers unique trim functions for the sailor.
It offers a Man Overboard function.
It offers a built in alarm with eight alarm settings.
It offers a control of the MAXI repeaters, up to nine units.
It offers the possibility to customise the display with your two favourite functions.
It can be configured to ”hide” pages you do not want to use, or conceal from curious hands.
The optional cable - cable connection (Art. No. 20966) gives you the flexibility to use it anywhere
on your boat. Simply disconnect it, and take it to your navigation table.
10
REMOTE CONTROL
To give you an idea of the versatility of what your Remote Control instrument can perform for
you, here is an example of a possible scenario:
Note! The Remote Control instruments NAV, WP and ROUTE pages must first be ”opened in
the setup to be used as described in this scenario!
You take your boat out of the harbour and start the Nexus Autopilot in Compass mode by use of the
Remote Control instrument, then while under way; you create some waypoints also used in the
sailplan.
Reset the trip counter, then enter Autopilot mode and activate the NAV function, the Autopilot will
follow the sail plan you just created.
Now you use the Remote Control Instrument to change information on your Nexus instruments.
When this is done, you check the water temperature before setting depth and boat speed as well as
geographical wind direction and true wind speed as the favourite functions in the BOAT page.
To alert your attention to the weather forecasts, you set the timer with a name for the particular
forecast. Before the coffee break, you check your expected time of arrival, wind speed and
geographic wind direction, at the same time as the Autopilot heads direct for your waypoint.

About this manual
•
Each time a push-button is referred to in this manual, the push-button name is written in bold
and CAPITAL letters e.g. PAGE RIGHT.
•
Unless otherwise stated, the push-button presses are momentary.
•
Each time a function is mentioned in the text, it will be in brackets and in the same format,
where possible, as displayed, e.g. [Lat].
•
With the word navigator we mean a GPS, Loran or Decca instrument.
•
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, i.e. 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.
•
Functions followed by the text ”optional" are not valid in factory default setting. See setup
mode to be able to display and use these functions.
Note! We have put in a lot of effort, in order to make this manual correct and complete. However,
since we have a policy of continuous improvement, some information may differ from the product
functions. If you need further information, contact your national distributor.

Installation
2.1
Installation general
Reliable and accurate operation of marine electronics depends very much on correct installation.
Please read and fully understand the installation requirements before attempting installation.
The installation includes 6 major steps:
1.
Read this installation and operation manual.
2.
Plan where to install the bracket and where to run the cable.
3.
Install the bracket.
4.
Run the cable, and connect the instrument.
5.
Take a break and admire your installation.
6.
Learn the functions and calibrate your Network.
Before you begin drilling... think about how you can make the installation as neat and simple as your
boat will allow. Think about how the cable will lie in the boat not to disturb any of your routines on
board.
The Remote Control instrument can be connected to the Nexus Server, or directly to any Nexus
instrument on the Nexus Network.
The bracket for the Remote Control can be mounted on almost any convenient location on the boat.
The instrument is waterproof, but should not be submerged in water for longer periods.
When selecting a location for your bracket and instrument, please ensure that they are at least
500 mm (20”) away from radio receiving equipment.
The instrument can be mounted right beside a magnetic compass.
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 run cables in 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 tools are needed:
• Wire cutters and strippers
• A pair of flat pliers
• Large Philips and small flat head screw driver
• Drill for the mounting holes, 2,8 mm (0,11”).
• 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 instruments and transducers.

Connection to Nexus Server or Nexus Instruments
Mark the desired location for the Remote Control bracket. Drill the three screw holes using a
2,8 mm (0,11”) drill. Mount the bracket using a Philips screwdriver.
Run the Nexus data bus cable from the location of Remote Control bracket to the Nexus
Server, or to a Nexus instrument.
Cut the Nexus data bus cable to length. Peel off about 35 mm (1,4”) of the cable insulation.
Remove about six mm (1/4”) from the three isolated wires (the 4th wire is a blank leader).
Attach the 4 cable protectors to the wires using a pair of flat pliers.
Apply silicon paste on all screw terminals. Note! Must be done to avoid corrosion.
Connect the four cable from the Remote Control to either:
a) The Nexus Server left hand side pins 5, 6, 7, 8, marked (Bus RS485).
NX2 Server
Other NX2
instrument
b) The four-pole jack plug at the back of the Nexus instrument.
To other NX2
Instruments
The pins or jack-plug are all colour coded to match the Remote Control wires.

Your installation is done!
2.2.1
Optional cable - cable connection
The optional connector (Art. No. 20966) allows you the flexibility to disconnect the Remote Control
to use it at a second location on the boat.
In this case the optional bracket (Art. No. 21218-1) is handy to use.
Further the optional eight metres (26 ft) Nexus data bus cable (Art. No. 21266-8 ) can be
supplied by the metre.

First start and initialising
3.1
Initialising the instrument
At power on, the instrument will perform a self-test, during which the
display will first show all segments, then the version number and the
Nexus Network ID number.
To initialise the instrument, press KEY on all installed digital instruments, one at a time.
Note: Always wait for the text ”Init OK” to be displayed, before you press KEY on the next
instrument!
The Nexus Server is automatically given ID number 0 (ID numbers 0 - 15 is reserved for transducers.
Therefore the first given ID number is 16, then 17 and so on. The order in which you press KEY is
the same order as the instruments will be given an ID number on the Nexus Network.
The drawing shows that the instrument version number is 1.0 and the given ID number is 18.
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 Network.
To re-initialise the instrument, press DOWN and UP together during the power
up sequence when version and ID numbers are displayed.
The instrument self-test is then re-started on all instruments and you will be
asked to (KEY PRESS) on each instrument as explained above.

Steer reference [Pilot]
The sub-function [Pilot] is intended for use together with
the optional analogue instrument Steer Pilot (Art no 205502) to assist the helmsman to keep the desired heading. The
same function is also used in the Compass Data instrument
(Art. No. 21487).
When a steer reference has been selected, the analogue
Steer Pilot instrument is automatically activated. It starts to
indicate the difference between desired and actual heading
and angle. The logic is to keep the Steer Pilot instrument
needle straight up pointing at 0 (zero) to stay on the set
heading.
In analogue Steer Pilot instruments from 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 4 KTS 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 in the Nexus Multi Control instrument.
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 Autopilot 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 from Nexus Server
version 2.6).

This function requires a Nexus or NMEA compass transducer. The function
displays the deviation from a set compass course value. When the optional
analogue Steer Pilot instrument or a Compass Data instrument is
connected, it will display the difference from the set course and the actual
heading.
The function is semi automatic, i.e. when activated, present compass heading is copied to
memory. You can later change the value manually.
Select sub-function [Pilot], press KEY. The text [OFF] or the last
selected steer reference function flashes.
To select steer reference [MEM], press UP.
To activate the function, press KEY. MEM is shown on the Multi

OFF] function. (Available from Nexus Server version 1.9.)
6.2.3
Steer reference, bearing to waypoint [BTW]
This function requires a Nexus or NMEA compass transducer and a Nexus
GPS or NMEA navigator. When selected, the function displays [BTW] and
the analogue Steer Pilot instrument displays the difference between the
compass heading and the [BTW].
The function can only be displayed if the connected navigator is navigating towards a waypoint.
Since the navigator controls the displayed value, the value can not be altered.
Select sub-function [Pilot], press KEY.
The text [OFF] or the last selected steer reference function flashes.

6.2.4
Steer reference, course to steer [CTS]
The function requires log transducer, a Nexus or NMEA compass transducer
and a 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 [CTS] including set and drift.
The function can only be displayed if the connected navigator is navigating towards a waypoint.
Since the navigator controls the displayed value, the value can not be altered.
The function is compensated for set and drift, by using 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 activate the function, press KEY. [MEM WP] is lit on the display.
The sub-function [Str] automatically displays the stored [CTS] value.
The function is invaluable when you want to sail the shortest distance to a waypoint.
6.2.5
Steer reference, apparent wind angle [AWA]
The function requires a Nexus or NMEA wind transducer.
The function displays the deviation from a set wind angle value, and can
together with the optional analogue Steer Pilot instrument be used as a
closed hauled indicator, or show an enlarged ”picture” of the tack or 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 activate the function, press KEY. [WIND] is shown on the Multi Control display.
th
The 100 digit for present apparent wind angle flashes and the symbol after the degree sign will
show wind from port or starboard .
If the wind angle is OK and you want to confirm the value, press KEY to lock it.
To set your own value, press DOWN, UP and MODE as required.
To lock the value, press KEY.
Use the analogue Steer Pilot as a ”close hauled” instrument.
Example: You have selected 35° starboard side [35° ] 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 175° port side 175°
as your running angle. When the needle on
the analogue Steer Pilot instrument points to 15° port side you are at 160°. When the needle is at
zero (0) you are at 175°. When the needle points 15° starboard you are at 190° starboard, having
accidentally gibed and successfully cleared the deck.
29
REMOTE CONTROL
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 combination that allows you to ”expand” the wind angles!
Note! Steer reference value [AWA] can also be selected directly from the optional trim pushbutton. The [AWA] function must first have been activated.
(Available from Nexus Server version 1.7.)
When a Nexus Autopilot is activated in wind mode, the [AWA] function can be used to perform an
automatic tack.
The sign
behind the wind angle value = port side.
behind the wind angle value = starboard side.
The sign
Simply change the value of the sign in front of the wind angle, and the Nexus Autopilot will gibe to
the opposite tack.
To summarise: The powerful combination of the Nexus Remote Control instrument together
with the analogue Steer Pilot actually offers you 6 functions.
Compass steering: [MEM]
1. Compass steering, using the one memory.
2. Headers and lifters, using the two memories and trim push-button [TAC]. (See 9.1).

Figure of merit [F] is a factor for the GPS reception quality on a
scale from one to nine, where [F1] =
best reception and [F9] = no reception.
[F] Is only displayed if you have a Nexus GPS connected.
The [HDOP] value should be as low as possible, a typical good
value is between 1.00 and 3.00.
The symbol [2D] means 2dimensional navigation with three
satellites, and [3D] means 3dimensional navigation with minimum
4 satellites, are displayed above the
top line.
If the [HDOP] value is more than ten
or if the [F] value is more than three,

When the route is activated and you arrive at each waypoint, an arrival alarm will sound
and the next waypoint in the route list will be activated automatically.
The ROUTE page can store up to 24 routes, with up to 24 waypoints in each route.
We recommend using Waypoints 0-50 for temporary waypoints, and the remaining
waypoints for the sailplans.
If you edit a waypoint that belongs to a route, the route will be affected.
9.1
Sailplan [SAIL PLAn]
When a route is created or activated, that is used for navigation, it
is called a [SAIL PLAn].
In the [SAIL PLAn] you can create or edit one sailplan with up to 24
waypoints.
If you have a Nexus GPS Navigator connected you can later store
the whole sailplan with the function
route store [ROUTE StorE].
If you have a Nexus Server as navigator you can use the sailplan, but not
store it.
A sailplan is consumed successively as the waypoints are passed. The last
waypoint is not cancelled automatically; it must be cancelled manually.

Man Over Board [MOB] function
This function will guide you back to the position where the man over
board [MOB] function was activated.
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), or a log and compass transducer.
If only a compass and a log transducer are connected, dead reckoning
[MOB] will be displayed on both the Multi Control and the Speed Log
instruments, if connected.
If a navigator, a compass and a log transducer are connected, dead
reckoning [MOB] will be performed and displayed in the Nexus Speed
Log instrument. At the same time the Nexus Multi Control instrument
will display [MOB] relative position stored in memory when the [MOB]
push-button was activated.
Dead reckoning [MOB] is very useful information, maybe even more
valuable than a ground related position. The dead reckoning [MOB]
position will be calculated according to the drift and set. A position in
latitude and longitude is more important for the sea rescue service.
The [MOB] position is automatically
stored in the last waypoint number (99 in Nexus Server, 399 in
Nexus GPS instrument), and cancels any earlier stored position in
these locations.
To activate the MOB function, press and hold PAGE LEFT and PAGE
RIGHT together for more than two seconds. The text M.O.B. is printed between the two push
buttons.
A fixed alarm signal will sound briefly to alert the crew.
The text [MOB] flashes in top right corner.
Off course error will be displayed in top left corner.
The sign
steer to right.
The sign
steer to left.
Bearing to the MOB position will be displayed at lower left corner.
Distance to the MOB position will be displayed at lower right corner.
All you have to do is to keep calm and steer the boat in the indicated
direction and distance to pick up your wet crewmember.
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.
46
REMOTE CONTROL
If a Nexus GPS and the analogue Steer Pilot instrument are 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
crewmember!

Autopilot mode
The Remote Control instrument can also control a Nexus Autopilot.
In autopilot mode it has 4 automatic steering functions:
Compass [HDG], Navigation [NAV], Wind [AWA] and Power Steer [PWR].
Operator Warning!
An Autopilot is an aid to navigation only. It is not intended or designed to replace the man on
watch. Always be in position to monitor the boat’s heading and to watch for navigational hazards.
Be prepared to revert to manual steering immediately, if an undesired change of heading occurs,
if the heading is not maintained within reasonable limits, or when navigating in a hazardous
situation.
Always remember: Whenever underway, a qualified man on watch is required.
It is the skippers responsibility to provide for a power safety switch, mounted within reach for the
helmsman, and to brief all crew members that the Nexus Autopilot must be turned off with the red
push-button KEY, to enable manual steering.

The rudder angle is displayed on the lower-line.
In any autopilot function, the top-line displays the heading at all times.
11.3
Autopilot functions
Prior to activating any automatic steering function, the boat should be steadied on the desired
heading and on track for 5 to 10 seconds to minimise large course changes when activated. The
Autopilot operates with course errors up to 90° and cross-track-errors of up to 2 NM.

[NAV] steering must be turned off when the waypoint is passed and you have another waypoint in
your sailplan.
50
REMOTE CONTROL
Caution!
The NAV function will automatically change course when the next waypoint information is
displayed and the helmsman should ensure that there are no boats or other hazards on the
new course as the waypoint is changing. When using waypoint sequencing in a route list, it is
extremely important that the helmsman is at the steering position and ready to override the
pilot if the course change would cause collision with other boats or objects.
Set all waypoints in navigators away from navigational hazards by at least 100 metres as the
boat may require this radius or more on waypoint advance. The Nexus GPS Navigator will
allow you to select a route list with automatic sequencing, or with a confirming push-button
press for each waypoint.
11.3.5
Automatic steering by wind angle [AWA]
Automatic steering by wind is only possible if the Autopilot is connected to a
Nexus Network with a wind-transducer connected.
Note! The apparent wind speed must be more than 3 knots. If the apparent
wind speed will fall below 3 knots, wind signals are disabled and the
Autopilot will maintain the current magnetic heading reference instead.
Before activating wind steering, first optimise your sail trim.
To select wind steering, press UP until [AWA] is flashing on the top-line. Your present course is
displayed on the top-line.
Starboard
To activate wind steering, press PAGE RIGHT when [AWA] is flashing.
The present [AWA] now becomes the reference angle, and is displayed on the lower-line to

Nexus data bus initiations [INI] and errors [ERR]
To select function [INI ERR], press DOWN.
[INI ERR] displays the status of the Nexus Network since power on.
[INI] displays the number of data bus initiations. At power on there are
normally a small number of initiations. During normal use, the [INI] value
should be constant. If the [INI] value increases, is it due to the fact that
two instruments have the same ID number on the Nexus data bus,
caused by that a press KEY has been done too quick during the Nexus
data bus initiation.
[ERR] displays the number of data packages that have a wrong checksum
(normally 0).
If the value increases, it can be that a data cable has a bad connection at
any instrument, or has a short circuit. Data can find its way even if one of
the two Nexus data bus cables are missing a connection, or even if there
is a short circuit near an instrument.

Transmit waypoints from the Server to a NMEA navigator or plotter, via
the NMEA sentence WPL. (See Server C78 WBN and C74 WPT).
The NMEA sentence WPL must be selected in one Server slot. (See
Server C79 to C94)
[OFF] = Transmission off. [On] = Transmission on.
It takes approximately 200 seconds to transfer 100 waypoints.
Note! When the transfer of waypoints are ready, we recommend that both
[REC WP] and [SEND WP] are set to [OFF], to avoid unintentional update of
the waypoint memory.

NMEA navigator [NMEANAV]
Possible settings are [On] or [OFF]. Default setting is [OFF].
Select which instrument you want to use for navigating. (See
Server C75 NAV).
By the term "navigating", we mean the active instrument, in which the
waypoint memory is used for navigation to calculate the navigation data,
i.e. BTW, DTW etc. There can only be one instrument on the Nexus
Network that is navigating.
[OFF] = The Server is navigating. One of the following NMEA
position sentences must be received for the Server to calculate
navigation data: RMC, GGA, RMA or GLL.
[On] = NMEA navigator is navigating. The Remote Control
instrument becomes a repeater of the information transmitted from
the NMEA navigator. Such as bearing and distance to waypoint etc.
See ”Receive NMEA sentences IN to Server from external
navigator”.
Note! If a Nexus GPS is connected, Server C75 will be ignored, that is the Server will
automatically take over the navigation no matter how C75 is set.
12.7.4.4.
NMEA compass transducer [NMEACOM]
Possible settings are [On] or [OFF]. Default setting is [OFF].
[OFF] = Nexus compass. [On] = NMEA compass. See Server C76.
12.7.4.5.
NMEA wind transducer [NMEAWIN]
Possible settings are [On] or [OFF]. Default setting is [OFF].
[OFF] = Nexus wind. [On] = NMEA wind. See Server C77.
12.7.4.6.
Waypoint base number [WP--BASE]
Possible settings are [00-99]. Default setting is [00].
1 base or block = 100 waypoints. See Server C78
Example 1: To receive waypoint number 101 to 150, from a NMEA
navigator and store them in memory 1 to 50 in the Server, set [WP--BASE]
to [01] and [REC WP] to [On].
Example 2: To transfer waypoint number 1 to 50, from a Server and store

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, plotter, radar etc.
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.
To cancel a NMEA slot, press DOWN and UP together.
It takes two seconds to transmit all 16 NMEA sentences.
To double the transmission speed, select a NMEA sentence two times with seven slots apart, that
is the slots should be as far away from each other as possible.
In a similar way, you can select 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 eight times which
makes the speed four times / second. This leaves the other eight slots with even numbers, C78,
C80, C82 ... C94 free to use for other NMEA sentences.
One of the advantages with the Nexus Network is the very fast transmission speed of data,
compared to the relatively slow NMEA standard (about ten times faster). Therefore we recommend
that you use Nexus instruments and transducers for better accuracy.
12.7.6
Receive NMEA sentences IN to Server from external navigator
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). Nexus 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). Nexus calculates true wind angle and wind speed, when the boat speed (the speed of
the water) is known.
The following NMEA sentences can be received IN to Server:
(AAM)
Waypoint Arrival Alarm.
(APA)
AutoPilot string "A" (old).
(APB)
AutoPilot string "B".
(BOD)
Bearing Original Destination.
(BWC)

All data (POSITION, BTW, SOG/COG, etc.) is received from one type of NMEA sentence. If data
is placed in different locations, the data will be selected from the sentence with the highest priority.
Example I: Position is read in priority order: RMC, GGA, RMA and GLL.
Example 2: 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 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.
See setting C13 and C37.

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.
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.
13.2
Fault finding
13.2.1
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 instrument and transducers, including their versions.
• Nexus Network ID numbers for each instrument (displayed at power up).
In most cases, the reason for faults in electronic equipment is to be found in poor installations.
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 10 V 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.
13.2.2
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 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. In the list below you will find some
explanations for disturbances to the measurement of depth and how it is expressed on the
instrument display.
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 Network specification
The Nexus Network is a high performance, non-collision multi talker multi receiver data bus,
specially designed for marine navigation applications. The most important features are the high
update rate, fast response times, very low data latency (25ms) and very high data security even at
long distances. Another important feature is that data transfer efficiency will not degrade even
when used in large and complex systems. It utilises the RS485 standard with up to 32 senders
and/or receivers to form a Local Area Network. Data is transmitted asynchronously with 1 start-bit,
8-data-bits, 1 parity bit, two stop-bits in 9600 baud.
The link between Nexus Network and your PC-application is the PC interface FD (Full Duplex) /
NMEA (Art. No. 21248-1). This is supplied with a 9-pole D-sub connector on a 1 m (3.3 ft) cable
for the RS232 PC port. The PC interface is a useful tool to monitor and log real time data, or when
editing waypoints to/from PC-file or to/from Nexus Network. For users who write their own
software, please see our web-site where you find the Nexus application notes.
