1.1
The Dataline-X System
The Dataline-X System, as its name implies, uses a single cable to carry both power and data around the vessel to each instrument. This is done using a
NMEA 0183 serial digital communication link, which is an established industry standard. Because of this, instruments from other manufacturers may be interfaced to the Dataline-X System - assuming that they have a NMEA output or input.
This User Guide describes the combined 360° Wind Angle and Wind Speed digital display, known as Dataline-X WIND, used within the Dataline-X System.

General Description
The display is divided into two sections, the pointer, and the LCD. Both are generally controlled by the MODE button.
2.1.1 The Dialplate
The pointer normally shows the 360
°
apparent or true wind angle, depending on the mode selected.
2.1.2 The LCD Display
The LCD normally shows one of the values below:
•
Apparent Wind Speed.
•
True Wind Speed.
• Wind Direction, (if a suitable heading or Course Over Ground data input is available).
•
Velocity Made Good to Windward (VMG)
There are three arrows at the top of the LCD which show which data is being displayed at any one time. The right arrow points to APP. on the dialplate for
'Apparent Wind', the left arrow points to TRUE on the dialplate for 'True Wind', and the centre arrow points to VMG on the dialplate for 'Velocity Made Good'.
2.1.3 The Buttons
The word below the button indicates the main function for that button.
The MODE button changes the current display mode when it is pressed, cycling around all the available data displays. If this button is held down is sets the damping level for all the displayed data.
The ALARM button (this button has a - symbol above it) shows the current wind speed alarm value if the alarm is on, or ‘OFF’ if the alarm is off. If this button is held down it sets the lighting level.
When a function has been selected, a BEEP will be heard to confirm correct operation.

Operation Part 2
Notes:
1. If there is no Wind Speed and Angle transducer fitted, but there are alternative NMEA Wind Speed and Angle inputs to the Databox, then this data will be used.
2. If there is no Boat Speed transducer fitted, but there is an alternative NMEA Boat Speed input to the Databox, then this data will be used.
2.3.1 Apparent Wind Angle and Apparent Wind Speed Display
This is the first display that is shown on power up. It is indicated by the right
LCD arrow being lit, showing 'App.' for 'Apparent'.
The wind speed is shown in the selected units, Knots, Metres Per Second,
Beaufort, or Kmh. All units except Beaufort are shown to one decimal place.
2.3.2 True Wind Angle and True Wind Speed Display
This display is indicated by the left LCD arrow being lit, showing 'True'.
The wind speed is shown in the selected units, Knots, Metres Per Second, Beaufort, or Kmh. All units except Beaufort are shown to one decimal place.
2.3.3 True Wind Angle and Wind Direction Display
This display is indicated by the left LCD arrow being lit, showing 'True' (Wind
Angle), with the LCD showing a three figure number with a degree sign at the right side which is the wind direction. The wind direction given is referenced to
Magnetic North.
If there is magnetic compass heading data available the Wind direction is calculated from this. In this case the wind direction given is the effective wind direction over the water. The display will be most accurate after a period on one heading, however it will respond rapidly to course changes.
If there is no magnetic compass heading data, but magnetic course over ground data is available then the Wind direction is calculated from the course over ground. In this case there is compensation for the tide, and the wind direction given is the effective wind direction over the ground. However the display will not be accurate after a course change, and will require a period on one heading before it is correct. (In addition, if the navigator used is a GPS then the
American Defense Department Selective Availability position errors will degrade the accuracy of the wind direction.)
Page 10
Part 2 Operation
2.3.4 True Wind Angle and VMG Display
This display is indicated by the left LCD arrow being lit, showing 'True' (Wind
Angle), with the centre LCD arrow also being lit, showing 'VMG'.
The VMG is shown in the selected units, Knots, Mph or Kmh. All units are shown to one decimal place.
Note: The VMG is shown as positive when heading upward, and negative when heading downward.
2.3.5 Apparent Wind Angle and VMG Display
This display is indicated by the right LCD arrow being lit, showing 'APP.'
(Apparent Wind Angle), with the centre LCD arrow also being lit, showing
'VMG'.
The VMG is shown in the selected units, Knots, Mph or Kmh. All units are shown to one decimal place.
Note: The VMG is shown as positive when heading upward, and negative when heading downward.
2.3.6 The Display Damping
All of the displayed data is damped together with one of four damping levels.
The damping level may be checked by pressing the MODE button and holding it down. The display will change to show the present damping level, as 'd1', 'd2',
'd3', or 'd4'. In order to change the damping level keep the button held down and the display will cycle through all four levels. Release the button at the desired damping level.
On power up damping level 1 is always selected.
2.4
The High Wind Speed Alarms
The Dataline-X Wind display has three high true wind speed alarms, either one, two, or all three of these can be used, and they can all be turned on or off as desired.
Page 11
Operation Part 2
2.4.1 The Alarm Displays and Turning the Alarm ON or OFF
Pressing the ALARM button will show ‘OFF’ on the LCD if the Wind Speed
Alarms are turned off, or the value of Wind Alarm 1 if the Wind Speed Alarms are turned on. After three seconds the LCD will return to the previous data display.
If there is only one wind alarm set then pressing the ALARM button again before the data display returns will change the alarm from off to on or vice versa. Thus repeated presses of the button will cycle the display between showing the alarm value, and ‘OFF’.
If there is more than one wind alarm set then pressing the ALARM button before the data display returns will cycle through all the set alarm values, and
‘OFF’. Thus to switch the alarm off, repeatedly press the button until ‘OFF’ is shown on the display. In order to simply check the alarm values and leave the alarm on then press the button to check each alarm value in turn, but ensure that the display is not finally left showing ‘OFF’.
2.4.2 Alarm Sounding
The alarms are system wide, and are sounded by all the Wind and Tack displays on the system. When an alarm sounds all of these displays will beep, and they will flash a warning message as below:
Wind Speed Alarm 1 Sounding (no others set) = 'HIGH'
Wind Speed Alarm 1 Sounding (others set)
Wind Speed Alarm 2 Sounding
= 'HI 1'
= 'HI 2'
Wind Speed Alarm 3 Sounding = 'HI 3'
If there is an external alarm connected then this will be sounded at the same time.
In order to cancel a sounding alarm press any button on any of the Wind or Tack displays.

Part 2 Operation
2.5
To Set Display Backlighting
1. Press the ALARM button and hold. The display backlighting will change from 0 to level 7, then level 6, then level 5, and so on to level 0. If the button is still held, the level will then increase back to
7 again.
2. At the desired display backlighting, release the ALARM button. This will set the lighting on ALL displays on the Dataline-X system, which are in the same Lighting Bank. The Dataline-X system has two lighting banks, so that the internal lighting on a power boat may be set differently to that on the flybridge, or the cockpit lighting may be set differently to the chart table or mast display lighting on a yacht. All displays are supplied set to bank 1. (See Part 4 for the bank set-up information.).
Note: On some Dataline Systems (not Dataline-X) only lighting levels 0, 3, 5 and
7 are available
2.6
Compass Sensor Error Displays
If the Dataline-X Wind display is used with a Dataline Compass Sensor then a number of Compass Error displays may be seen if there is a fault with the sensor.
These will be shown instead of the normal Magnetic Wind Direction display, and can be cancelled by pressing either button. If an error is seen then the compass sensor should not be used for navigation until the error has been corrected.
The error messages consist of a display of 'Err' and a number which identifies the nature of the error, as below:
‘Err4' = Memory Error, contact your dealer for advice.
'Err6' = Battery Voltage is below 11 Volts.
If any other errors are seen (and the compass sensor is not in auto deviation compensation mode - See Part 4) consult your dealer for advice.
Page 13
Operation Part 2

Demonstration Mode
The Demonstration Mode allows the user to familiarize himself/herself with all the functions of the instrument with the device removed from the system.
Demonstration software within the instrument produces realistic values for the display.
A +12V power supply will be required to be connected as follows:
0V to the BLACK (far right) terminal.
+12V to the RED (far left) terminal.
To enter the Demonstration Mode, press the ALARM button whilst applying power to the instrument.
To leave the Demonstration Mode, switch off and re-apply power.
Notes:
1. The display will leave demonstration mode if any data is received.
2. The display can be set to automatically enter 'Shop’ demonstration mode every time it is powered up. (See Part 4 for further details.)

3.1
General
The instrument head is fully waterproof and can, therefore, be installed on deck or below. The connections should be protected from water penetration and should, if possible, allow rear access to remove the desiccant pack, if required. The position selected should, in the first instance, meet the requirements of the helmsman, or crew.
The selected surface for the instrument head must be flat and even to within
0.5 mm.
Before installation, note the Serial Number of the unit and keep it in a safe place.

Installation
1. Carefully position the self-adhesive template provided on the surface where the instrument is to be mounted.
2. Drill a small pilot hole first, and then check the location on the other side of the panel or bulkhead to confirm suitability.
3. Open out the pilot hole to 50 mm (2 ins.) using a cutter in a handheld brace, or electric drill.
1. Drill the four fixing holes using a 2.5 mm (3.32 ins.) drill.
Figure 3.2 - Mounting Details (Not To Scale)
2. The instrument should next be wired into the system. The wiring should be carried out as in the ‘Choosing the Cable Routes’ and
‘Securing the Cable’ Sections below.
a. If the instrument is being connected to a Dataline-X system, then connect it to the Dataline wire. This can normally be done simply by using the ‘Dataplug’ connector and cable supplied to connect the display to the Databox or to any adjacent display.
Page 17
Installation Part 3
If the cable routing cannot be made with the Dataplug connector attached, then simply disconnect it from the cable. The cable may then be run through holes of down to 6 mm (0.25 ins.) diameter before reconnecting the Dataplug connector, making sure that the colours are correctly wired to the terminals. The correct positions for the different coloured wires are shown on the rear label of the instrument.
b. If the instrument is being connected to another instrument system then the connections are as below:
Red = +12V Power In (Fused 1A).
White = NMEA Signal In (A / + / Positive).
Brown = Wind Alarm Output (30mA).
Green = NMEA Reference In (B / - / Negative).
Black = 0V Power In.
Figure 3.3 - Electrical Connections
6. Check that the instrument functions correctly.
7. Temporarily disconnect the Dataplug connectors and coat the terminals and wires with silicone grease or petroleum jelly. These products will not harm the instrument.
8. Make sure the ‘dovetail’ lugs are free from grease and securely located into the rear of the instrument when replacing the
Dataplugs.
9. Secure the instrument using the four, No 4 self-tapping screws provided. Ensure that the sealing gasket is correctly located.
10. Replace the front cover, the installation of the instrument is complete.

Part 3 Installation
CAUTIONS
DO NOT OVER-TIGHTEN FIXING SCREWS.
DO NOT USE SEALING COMPOUND ON THE
INSTRUMENT BACK.
DO NOT USE WD40 OR ANY SOLVENT ON ANY PART
OF THE INSTRUMENT.
3.3
Choosing the Cable Routes
After you have decided on the system and started to mount the components of the Dataline-X System, the next step in the installation process is to route the cables between the various parts of the system and to the power supply. When routing the cables, choose the most direct paths while avoiding the following hazards:
•
Sharp bends or kinks in the cable
• Hot surfaces (exhaust manifolds or cooking equipment)
• Rotating or reciprocating equipment
• Sharp or abrasive surfaces
• Door and window jambs
•
Corrosive fluids or gases
3.4
Securing the Cable
After the ideal cable routing has been established, use tie-wraps, ‘P’ - clips or other fixings to secure the cables along the routings.
Notes:
1. To prevent chafing add protection for the cable jackets where the cables pass through bulkheads, or past sharp edges.
2. Secure the cable near to the terminals for strain relieving.
3. Secure the cable ends with enough slack to allow for easy connection.
4. Cut any spare wire ends to an appropriate length.

4.13 Automatic Compass Deviation Compensation
This function is only of use if the system is using a Dataline Compass Sensor.
This sensor can automatically compensate for magnetic deviation. In order to compensate the compass first select the auto deviation compensation screen in the Wind Displays Calibration mode, and then command the Compass Sensor to perform its Automatic Deviation Correction Calculation. When the Sensor has started the process the vessel should be slowly steered in a number of circles until the sensor signals that the process has been finished. This will normally take up to four rotations.
1. Press both pushbuttons together, and hold for more than 3 seconds, until 'rEd', 'Grn', or 'YEL' is shown on the display.
2. Press the MODE button four times until the LCD shows 'HdG' and a number or letter. The number or letter indicates the status of the
Compass Sensor, as below:
'HdG0' = The Compass Sensor is Not Deviation
Compensated.
'HdGc' =
'HdG4' =
The Compass Sensor is already Compensated.
Memory Error, contact your dealer for advice.
'HdG6' = Battery Voltage is below 11 Volts.
3. If any other number is seen then this is another error, so consult your dealer for advice.
Page 29
Setting-Up Part 4
4. If the LCD shows 'HdGc' then the compass sensor is already compensated. However if it needs to be compensated again due to movement of metal or magnetic objects in its vicinity then press both buttons. The LCD will show 'Hdg ', and then after a short time it should show 'HdG0' to indicate that the sensor is no longer compensated and is ready to be compensated again.
5. If the LCD shows 'HdG0' then it is not compensated, and is ready to be compensated, so continue with the steps below.
6. Place the vessel in a position where it can be swung through a full
360 degrees.
7. Align the vessel to approximately 270 degrees. It must not be at a heading of below 180 degrees.
8. Press both buttons. The LCD will show 'HdG ', and then after a short time it should change to 'HdGi' to show that the process has been initiated. If it is desired to stop the process press both buttons again.
9. Begin swinging the vessel, either by hand or by motoring circles.
The rate of rotation is not critical, but about one minute per revolution is suitable. During this process the LCD will change to show 'HdGr', indicating that the calibration process is running. If at any time the LCD shows a number after 'HdG' then an error has occurred, as below:
'HdG1' = Upon initiating the procedure the heading was less than 180 degrees, restart the procedure with a heading of approximately 270 degrees.
'HdG2' = The speed of rotation is too slow, restart the procedure making sure that the speed of rotation is faster.
'HdG4' = Memory Error, contact your dealer for advice.
'HdG6' = Battery Voltage is below 11 Volts.
12.
If any other number is seen then this is another error, so consult your dealer for advice.
13. After a number of rotations the LCD will change to show 'HdGc', indicating that the calibration is complete.

Fault Finding Chart
5.1 General
This instrument has been tested before shipment. However, installation conditions and procedures are outside the control of the manufacturer and can sometimes produce faults. The following check list is provided to assist the user in diagnosing such faults and suggests remedial action to be taken. The built in Test Mode will also help diagnose faults. For additional assistance, call your local dealer.
5.2 Test Mode
The Test Mode will test all the display functions.
1. Press both buttons together, and hold for more than 3 seconds, until
'rEd', 'Grn', or 'YEL' is shown on the display.
2. Press the MODE button three times, until the LCD shows 'tESt'.
3. Press both buttons together to start to set Test Mode On, the current value, ‘OFF’, will be shown flashing.
4. Select Test Mode On by pressing either button on its own, the LCD will show ‘ON’ flashing.
5. Press both buttons together to start Test Mode.
If it is decided not to start Test Mode then press either button to change the
LCD back to flashing ‘OFF’, then press both buttons to return to showing
'tESt'. Return to the main display by pressing the ALARM button twice to select the Calibration Mode End Screen, and then pressing both buttons together.
Test Mode
The display will go through six tests. In order to move on to the next test, press the MODE button. In order to leave test mode, press the ALARM button.
First the LCD will light all the segments and the pointer will return to the zero position. The LCD will then blank.
Page 33
Fault Finding Part 5
Pointer Test
The LCD will then show the software code version, and after a few seconds the pointer will start to move backwards and forwards through its whole movement. This will be repeated until a button is pressed.
LCD Segments Test
After the pointer test, the display will show 'tSt2’, and start the LCD test. This will light every one of the segments on the LCD one by one. They will then be turned off one by one until they are all off again. This will be repeated until a button is pressed.
LCD Contrast Test
After the LCD Segment test, the display will show 'tSt3' and start to swap between the two LCD contrast levels, showing 'LCd’ and the contrast level.
This will continue until a button is pressed.
Lighting Test
After the LCD Contrast Test, the display will show 'tSt4' and start to cycle through the various lighting levels and colours. There are four red lighting levels (r8, r4, r2, r1), three green levels (G4, G2, G1) and three yellow levels
(L4, L2, L1). This will continue until a button is pressed.
NMEA Input Test
After the lighting test, the display will show 'tSt5’ and start to monitor its
NMEA input. It will show 'IN’ and a count of the successful inputs up to five, when it will automatically step onto the next test.
If the display is receiving NMEA data, the count should happen without any actions on the user’s part. If the display is powered up on its own, then its
NMEA input (White) may be connected to the 12V power (Red) five times to simulate an input.
NMEA Output Test
After the NMEA Input test, the display will show 'tSt6’ and step onto the
NMEA output test. If the display is connected to a Databox, then it will automatically transmit messages to the Databox and monitor the NMEA input for correct replies. This will count up from 1 to 5 while showing 'OUT’. (A failure here could be a wiring or Databox problem, however.) If the display is not on a Databox, then its NMEA Output (Brown) should be connected to the
NMEA Input (White) and the display will transmit directly to itself.
Page 34
Part 5 Fault Finding
After a successful test, the display will automatically step on to the next test.
Button Test
After the NMEA Output test, the display will show 'tSt7’, then test the two buttons, prompting with the button number. After a successful test of both buttons, the display will automatically return to normal mode.
The buzzer should beep on every button test.
