2 Installation

You can install the NX2 Compass in three different ways:

• The compass transducer connected directly to the NX2 Compass instrument

• By using the connection kit when both log and compass transducers are installed with a single cable to the NX2 Compass instrument.

• The installation may also include a NX2 Server where all transducers may be connected. All data including power will pass along one cable.

• The installation includes 6 major steps:

1. Read the installation and 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.

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.

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 pinbolts to the instrument

• Put the instrument in place

• Screw the two nuts from the back

Note! The two nuts must just be tighten by hand

• 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.

• 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.

Silicon paste

2.1.1 Connections in Nexus Network

If you already have a Nexus Network i.e. a Server, it is more practical to connect the transducer to the Server due to the single instrument cable installation. Note, Set C71

OFF (see 5.4.1).

2.1.2 Connection to a HPC Compass

If you already have a Nexus Network i.e. a Server, it is more practical to connect the transducer to the Server due to the single instrument cable installation. Note, Set C71

OFF (see 5.4.1).

2.1.3 Connection of a 35 or 45 degree compass

The power cable is connected via a 3A fuse from the battery or at the boats fuse panel and direct to the instrument or Server. One red and one black power wire is included.

Note, Set C71 ON (see 5.4.1).

Always connect a 3 AMP fuse between Power supply and instrument.

3 First start

At each power on, the instrument will first show all segments lit up, then the ID number and software version [VER]. Number 8 is the fixed ID when the Compass transducer is connected direct at the instrument and the setting in C71 is on (default setting).

3.1 Initialising the instrument in a Nexus Network

At the first power on after installation, you will be asked to press SET

[PrSKEY]. This will give the instrument a logical ID number from 16 and upwards on the Nexus Network.

To initialise the instrument, press SET, one at a time, on all installed digital instruments,.

Note: Always wait for the text ”Init OK” to be displayed, before you press SET

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, will be the same order as the instruments will be addressed by the Remote Control, if used.

The example shows that the instrument version number is 1.00 and the given logical ID number is 16. The ID number will always be 8 if the Compass transducer is connected to this instrument. If the instrument is a repeater, it may have any number from 16 and up.

3.2 Re-initialising the instrument

If and when two instruments by mistake have the same ID number, you must re-initialise the instruments to avoid network disturbance and blockage of data.

To re-initialise the instrument, press MINUS and PLUS together during the power up sequence, i.e. when version and ID numbers are displayed.

The display test is then re-started on all instruments and you will be asked to press SET (ANY KEY) on each instrument as explained above.

Note! If you do not succeed to re-initialise, we suggest you disconnect (just pull out the connection plug) all, except one of the instruments that had the same ID number, then repeat the above procedure. Reinstall the instruments and redo the ”PRESKEY” procedure.

4.5.3 Advanced use of (STR) MEM

The text [STR OFF] or [MEM] is displayed.

Press CLEAR. The text [OFF] or [MEM] is flashing, select one of the following four different steering modes that are available; [MEM],

[AWA], [BTW] , [CTS] or [OFF] and press SET.

Each function is explained in detail. The function [STR] is a Nexus network function, i.e. it will transmit the steer reference data to other

NX2 instruments. The steer information used on the Compass Data instrument is functioning within the same concept as the STEER

Pilot instrument. The instrument is especially designed for displaying steer or Compass heading information in the most efficient way. You may also use one or more external TRIM buttons to set new references. To be able to utilise the wind steer function

AWA, you will need either a Wind Data instrument, or a NX2 Server with a wind transducer. For the [BTW] and [CTS] functions you will need a NX2 GPS or any NMEA GPS ,Decca or Loran C navigator to be connected.

Also, if you have installed a NX2 Autopilot, and it is activated, you may change the course or wind angle by using the STR function.

You can not activate or turn the pilot off with STR, so use with care !

4.5.4 Steer referens [AWA], option

The text [OFF] or [MEM] is displayed.

This function may be used when sailing upwind or downwind, where

Compass course is chosen to be the secondary steer priority, after windangle.

Press CLEAR. The text [OFF], [MEM] or the previous selected function is flashing, select [AWA] and press SET.

A copy of the present windangle is flashing, press SET to accept, or enter preferred windangle, then confirm with SET.

You will now see the text WA flashing with a pointer at the left or right side. For now, just press the SET again, then press PAGE to see the closed hauled angle.

Example, you have set 40° as your tacking angle.

The boat is sailing with the pre-set wind angle when the LCD pointer is displayed as a vertical line strait up. A windangle deviation is displayed as a filled sector. When sailing too high, segments are above the horizontal line and when sailing too low, segments are below the horizontal line.

COMPASS

5-18

COMPASS

The windangle referens [AWA] is also sent out to all NX2 instruments and the STEER Pilot will also show you the deviation from your set angle.

The AWA can also be used downwind, as a jibe warning indicator, or to keep the fastest downwind speed.

When the [AWA] was selected, the text [WA] was flashing with a left or a right pointer. This function is used to perform an automatic tack when the NX2 Autopilot is installed (and activated for wind steering).

Use the PLUS and MINUS to change the direction of the WA pointer, then press SET.

Your NX2 Autopilot, if activated in wind mode, will now perform an automatic tack.

4.5.5 Steer referens [BTW], option

The text [OFF] or [MEM] is displayed.

This steer function will give Compass course, true or magnetic relative bearing to Waypoint. It must be used together with a GPS or

Decca/ Loran C navigator connected to the NEXUS network (at the

Server or at the GPS instrument).

Press CLEAR. The text OFF, MEM or the previous selected function is flashing, select [BTW] and press SET.

The steer referens [BTW] is automatically calculated.

4.5.6 Steer referens [CTS], option

The text [STR OFF] or [MEM] is displayed.

This steer function will give course to steer, true or magnetic relative bearing to Waypoint, including compensation for drift. It must be used together with a GPS or Decca/ Loran C navigator connected to the NEXUS network (at the Server or at the GPS instrument). The

NX2 log transducer must also be installed.

Press CLEAR. The text [OFF], [MEM] or the previous selected function is flashing, select [CTS] and press SET.

The steer reference [CTS] is automatically calculated.

Hints !

Even if your Compass is un-deviated, the CTS function will anyway tell you the optimum course to sail !

The CTS function gives you the shortest way to sail towards the Waypoint. Tide must however be taken into consideration, since it will give a time dependant drift on the boat.

4.5.7 Tactical use of [MEM]

Function [MEM] is used to discover the smallest of wind shifts during upwind or downwind sailing, but it is your tactical decision wheter to tac or to stay on course. The Compass Data instrument will automatically keep track on wheter you are using the starboard or port MEM if the course difference between each trim is more then

45º. There is also a new function called [KTR] (Knock TimeR), giving you the time spent i seconds when sailing below a preset

”knock Angle”. Both [MEM] and [KTR] will help you to get a very good ”picture” over actual windshifts, both in size and time.

How does it work ?

On the optimum compass heading, press the trim or SET button to store your present course in the memory called MEM. Your actual course is then constantly compared with MEM and displayed as a lift or as a header. Each time you press trim or KEY, a new reference course is set.

How to use the MEM function:

When you are sailing at a good speed and with the sail trimmed, press trim or SET. The Compass Data will then store the present course in memory MEM as a reference. If you then have a lifter, press TRIM again, but if you have a header more then 5º-10º, tack.

After you tack, re-trim the sails and get a good boat speed before you press trim or SET again. Now you have set a new reference in the memory. Whenever you get a lifter, press TRIM, but when you get a header, tack. Your previous trim reference will automatically be displayed and used.

Now, add the KTR timer

The timer must first be activated. This is done by setting the CAL value C-17 to the maximum angle where you consider your boat to be pushed off course, i.e. where you normally would tac when getting a header. See more under [KTR] setup.

4.5.8 Battery voltage [BAT]

The text [BAT] will display battery voltage. The voltage is measured inside the instrument and will not compensate for any voltage drop caused by installation.

4.5.9 Boat speed [BSP], option

The text [BSP] will display boat speed (water speed). The text [BSP] will toggle with selected unit, i.e. (KTS), (KMH) or (MPH).

As an option, you may add or remove displaying boat speed

[BSP], trip log [TRP] and water temperature [TMP]. See calibration.

COMPASS

5-20

COMPASS

4.5.10 Trip log [TRP], option

The text [TRP] is displayed and will show trip distance from 0.00 to

99.9 nautical miles, kilometre or miles. After 99.9, 0.00 is displayed.

Clear trip by pressing CLEAR.

4.5.11 Water temperature [TMP], option

The text [TMP] is displayed with water temperature in Celsius or

Fahrenheit.

This function requires a NX2, Nexus or Star log transducer.

4.5.12 Dead reckoning [CMG / DMG]

This function requires both Compass and Log transducers.

The text [CMG] (Course Made Good) is first displayed, then, after some seconds the text [DMG] (Distance Made Good) is displayed.

The two functions are alternating. When the instrument is powered up, the CMG/DMG function is cleared. Then, while underway, the function will continuously calculate the shortest travelled distance

[DMG] and the averaged travelled course [CMG], from start or reset.

You may clear and restart the dead reckoning manually by pressing

CLEAR.

4.5.13 X-track error, [XTE], Option

To get this function, set NAV = On C14 (See 5.1.3).

The text [XTE] is displayed shortly when this function is selected, then a symbolic ”boat” is displayed on one side of the ”road” which is displayed as three vertical lines.

Your ”boat” will be displayed on the right or left side of the symbol.

The distance is also displayed and can be in either Nautical mile,

Km or Miles.

4.5.14 In a small NEXUS network

The Compass Data instrument can be used in a small Network together with the Speed log, Multi Repeater or analogue instruments, without a Server.

When both the log and Compass transducers are installed at the

Compass Data instrument, we recommend you to install by use of the connection kit art.no. 21453. Only one cable will then carry all the signals between the instrument and the connection box.

Additional NX2 instruments may be connected direct at the

Compass Data instrument. One NEXUS Network power/data cable will then go to the additional Multi or Log instruments. (See 2.1.3).

5-21

English

English

When using the Compass Data in a Network with more then 3 transducers, we recommend you to use the NX2 Server. One Nexus

Network power/data cable is used to connect all instruments. You will have NMEA 0183 in/out. Depth information will (if used) be repeated at more than one NX2 instrument.

Network bonus function:

When you are using the race timer on the Multi or Log instrument, a graphical countdown timer will pop up the last 60 seconds.

In this example there is 45 seconds to the start.

5.1.4 C15 Beep when KEY is pressed

Setting KEY On will make a beep at every KEY-press, and when

KEY is OFF, There is no beep.

5.1.5 C16 Referens pointer On/OFF

Setting REF On will show a reference pointer in the true direction as a steer indicator in the Compass graphical mode. When set to OFF, no reference indicator will be visible. When the indicator is activated and a MEM course is set, this pointer will slowly ”blink” and when overlapping your Compass pointer, you are on course.

5.1.6 C17 ”Knock Timer” KTR

This is a race sailing function that will help you to decide when to tack. When activated, a ”knock timer” will pop up when you are sailing lower than the ”knock angle”. When the ”knock angle” is set to 00 it is OFF.

Example, when KTR is set to 15° and you are ”knocked” i.e. sailing

15° lower than the ”reference set” course for more than 5 seconds, a timer will pop up, telling you the elapsed time spent at ”knocked” angle. Also read chapter 4.5.3 Tactical use of MEM.

5.2 C20 Calibration of Log

To return to normal mode, press SET when the text [rET] is displayed.

5.2.1 C21 Select unit for speed

Unit for speed, knots (KTS), km/h (K/h) or miles/h (m/h).

5.2.2 C22 Calibration of log transducer

Calibration value for speed and distance (1.00 - 1.99).

Drive the boat a measured distance at normal speed.

Compare the distance with the trip counter.

Calculate the value with the following formula.

True distance from the sea chart: T

Log trip counter distance: L

5.3.2 C32 Magnetic deviation, VAR

Set the deviation direction first, i.e. [+E] (East) or [W] (West), then enter the magnetic value in 1/10 of a degree.

5.3.3 C33 Autodeviation

This function is used to autodeviate your Compass. Take the boat into a turn, in calm sea, when steady, press SET to start.

The text [DEV] starts flashing and a LCD sector will show you the course where to end. When you have taken the boat through the minimum 360° turn, press SET again, and if successful, the text

[DEV Atd] will appear again. If you read ERR 17, the Compass magnetic variation have been too small. That is, if you either interrupted the deviation too soon by pressing SET before done, or if the Compass is affected by strong magnetic distortion.

5.3.4 C34 Check the Autodeviation

This function is used to check your Autodeviation. Make a new

Autodeviation in calm sea (during the evening) as described in

5.3.3, and you may (or not) take the boat the opposite direction as when Autodeviated.

The text [CHK] starts flashing and a pointer will show you the course where to end. When you have taken the boat through the minimum 360° turn, press SET again, and if successful, the text [CHK Atd] will appear again, otherwise, ERR 17 or ERR 19 will appear, i.e. the difference between the last Autodeviation and this Autocheck is to big to be accepted. Make a new Autocheck, and if you still get ERR

19, make a new Autodeviation since the last one was probably disturbed.

When the Autocheck is OK, the Compass will store the average result from both Autodev and Autocheck.

5.3.5 C35 Clear the Autodeviation

If you by any reason prefer to reset the deviation created by the

Autodeviation function, press SET when text [CLR Atd] is displayed, you are now asked to confirm the flashing text YES by another press on KEY, or select no by use of PLUS or MINUS button, then SET.

5.3.6 C36 Adjust the Compass alignment

This function is used when the Compass is giving a constant course error, i.e. it is not mounted exactly aligned as the boat (there is no need to mount the transducer at the boats centreline). Make sure that the local magnetic variation is entered before you make the alignment adjustment, otherwise you are unable to see the difference between local magnetic variation and alignment error.

The Compass may be installed reversed 180° , but never at perpendicular, or 90° relative the centreline.

Press the SET and adjust [ADJ

the angle by entering the error. If you want to add 5° enter 005°. If you want to subtract 5° enter 355°

(360- 5).

5.3.7 C37 Off course alarm

This function is used to set a course alarm that will be activated when the boats average course is more thenset value. The text

[OCA OFF

] is displayed. Press SET to enter the maximum allowed course error, then press SET again.

This function is filtered for 30s to avoid false alarms such as when sailing in heavy sea. Set to 00 will turn alarm OFF.

5.3.8 C68 Roll adjustment

This adjustment is valid only if roll is selected in C73 (you have to exit and enter the calibration again after C73 is set to Roll).

Adjustment of the roll offset. Mount the roll transducer according to the instructions. Adjust the offset so the roll is displaying 00° when

5-26

COMPASS

COMPASS the boat is horizontal. By entering a minus sign [-] in front of the value the roll will be decreased by the value. When the offset is without a minus sign, it will be added. When a roll transducer is connected, both wind speed and wind angle will be compensated for the roll and thus increasing the accuracy.

The roll sensor is not available at the time for this manual.

5.3.9 C69 Pitch adjustment

This adjustment is valid only if roll is selected in C73 (you have to exit and enter the calibration again after C73 is set to Roll).

Adjustment of the pitch offset. Mount the pitch transducer according to the instructions. Adjust the offset so the pitch is displaying 00° when the boat is horizontal. By entering aminus sign [-] in front of the value the roll will be decreased by the value. When the offset is without a minus sign, it will be added.

The pitch sensor is not yet available (at mars 1997).

5.4 C70 Configure NX2

To return to normal mode, press SET when the text [rET] is displayed.

In the configuration you will be able to tell the Nexus Network where you have installed the log and wind transducer.

This is important because you may optionally install those transducers at the Server instead of the instrument.

5.4.1 C71 HDC-master

[On] = the Compass transducer is connected at the Compass Data instrument.

[OFF] = the wind transducer is connected at the NX2 Server.

5.4.2 C72 Log-master

[On] = the log transducer is connected at the Compass Data instrument.

[OFF] = the log transducer is connected at the NX2 Server.

5.4.3 C73 Function on terminal In3

Select function on the terminal pin 3. The following functions are available:

If other function then water temperature is selected, you may still use the water temperature function by connecting the NX2 log transducer at the Server or at the Wind Data instrument.

[TMP] Standard temperature function for the log transducer.

[TRM] Use the external trim button for the SPEED Trim function.

[STR] Use the external trim button for the STEER Pilot function.

[MOB] Use the external trim button for the M.O.B. function.

[Roll] Use the roll sensor to compensate wind speed and angle.

(Not yet available, at the time for printing this manual).

When the selection roll is made, further settings in calibration can be made to correct the offset angle. See C68 5.3.8.

When Speed TRriM [TRM] is selected, a press on the external trim button will transmit the trim command on the Network. To be able to set both steer and trim reference, the optimum way is to connect one trim button for speed to the Compass Data instrument and one trim button for steer at the Server. Such an installation gives you the opportunity to trim both speed and steer with separate buttons.

7.2 Nexus Network introduction and user policy

Introduction:

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 very 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.

User policy:

The Nexus network is open for new users and applications without a licence or licence fee. The easy link between Nexus network and your PC-application is the full duplex

PC interface (Art. No. 21248). The interface comes with software and is supplied with a

9-pole D-sub connector cable for the RS232 PC port. The PC interface will be a very useful tool to control and monitor real time data, or when editing Waypoints to/from PCfile or to/from NX2 GPS or Server. For users who writes there own software, please contact SILVA SWEDEN and ask for NX2 Application notes.
