FCC Statement

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a normal installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.

Increase the separation between the equipment and receiver.

Connect the equipment into an output on a circuit different from that to which the receiver is

Important

The choice, location, angle and installation of the instrument & GPS antenna are critical to performance of the system as intended. Follow instructions in this manual carefully. If in doubt, consult your Northstar dealer.

Ensure that any holes cut are in a safe position and will not weaken the boat’s structure. If in doubt, consult a qualiﬁ ed boat builder.

Global Position System: The global Position System (GPS) is operated by the U.S. Government which is solely responsible for its operation, accuracy and maintenance. The GPS is subject to changes which could aﬀ ect the accuracy and performance of all GPS equipment anywhere in the world, including the 557/567 and 650, 657, 660. To reduce the risk of misusing or misinterpreting the 557/567 and 650, 657, 660, you must read and understand all aspects of this Installation & Operation Manual. We also recommend that practice all operations using the built-in simulator before using the 557/567 or 650, 657, 660.

Electronic Chart: The electronic chart used by 557/567 or 650, 657, 660 is an aid to navigation designed to supplement, not replace oﬃ cial government charts. Only oﬃ cial government charts supplemented by notices to mariners contain the information required for safe and prudent navigation, Always supplement the electronic information provided by 557/567 or 650, 657, 660 with other plotting sources such as observations, depth soundings, radar and hand compass bearings. Should the information not agree, the discrepancy must be resolved before proceeding any further.

AIS: The AIS features on this chart-plotter are designed as a safety aid only and do not guarantee safety at sea. AIS transmission is mandatory on some, but not all, vessels. You should check your local laws and regulations for requirements in your area. As a result of diﬀ erent legal requirements, diﬀ erent vessel sizes and uses, you should not assume that your AIS equipped chart-plotter will show the location of ALL vessels in your area. Careful prudence, judgement, and safe navigation practices should be always be exercised. AIS should be used to complement radar, but AIS is not a substitute for radar.

Fuel Computer: Do not rely on the fuel computer as the sole source of information regarding available fuel onboard. Fuel economy can change drastically depending on boat loading and sea conditions. Fuel Computer information should be supplemented by visual or other checks of the fuel load. This is necessary due to possible operator errors such as forgetting to reset the fuel used when ﬁ lling the tank, running the engine with the Fuel Computer not switched on, or on other operator actions that may render the device inaccurate. Always carry adequate fuel onboard for the intended trip, plus a reserve to allow for unforeseen circumstances.

Failure to adhere to these warnings may lead to death, serious injury or property damage. Northstar disclaims all liability for installation or use of this product that causes or contributes to death, injury or property damage or that violates any law.

The 557/567 is set up with default units. To change the units, see section 15-9

3 Navigation: Chart

The chart window shows the chart, the boat’s position course and navigation data.

3-1 Overview of navigating

The 557/567 has two ways of navigating, going straight to a point or following a route.

3-1-1 Navigating to a point

When the 557/567 is navigating to a point, the chart and highway windows show navigation data:

A The boat position .

B The destination point marked with a circle.

C The boat’s plotted course to the destination.

D Two CDI lines, parallel to the boat’s plotted

course, which indicate the maximum expected deviation from the plotted course.

For more information, see appendix C.

If the 557/567 is connected to an autopilot, the 557/567 will send data to the autopilot to steer the boat to the destination. Start the autopilot before starting to navigate to the point.

If the 557/567 has no autopilot, steer the boat manually:

a use the boat position and destination on the chart or highway windows

b or use navigation data window on the data header (see section 2-8-3)

c or use COG and BRG on the compass (see section 2-8-4).

Note:

1 If the XTE alarm is enabled, an alarm will

sound if the boat deviates too much from its intended course (see section 15-8).

2 If the arrival radius alarm is enabled, then an

alarm will sound to show that the boat has reached the destination (see section 15-8).

3-5 Tracks and trackin g

Tracking records the boat’s position to memory at regular intervals, which can be:

Time intervals.

Or distance intervals.

The track of where the boat has been can be displayed on the chart. The 557/567 can display one track while recording another.

To work with track s, see section 15-5.

The 557/567 can store five tracks:

Track 1 can hold up to 200 0 points and is intended to record the normal progress of the boat.

Tracks 2, 3, 4 and 5 can hold up to 500 points each and are intended to record sec tions to be retraced accurately, for example entering a river mouth.

Tip: Record the tracks in good conditions.

When recording is on and the track becomes full then recording continues and the oldest points in the track are deleted. The maximum length of a track depends on the selected track interval: a small interval will give a shor ter, more detailed track and a long interval will give a longer, less detailed track, as shown in these examples:

The track lengths are in the current distance units, for example nm.

7 Satellites

GPS worldwide navigation

The US Government operates the GPS system. Twenty-four satellites orbit the earth and broadcast position and time signals. The positions of these satellites are constantly changing. The GPS receiver analyses the signals from the closest satellites and calculates exactly where it is on earth. This is called the GPS position.

The accurac y of the GPS position is typically better than 10 m (33 ft) for 95% of the time. A GPS antenna can receive signals from the GPS satellites when it is almost any where on earth.

DGPS

A DGPS system uses correction signals to remove some of the errors in the GPS position. The 557/567 can use one of two types of DGPS system:

WAAS and EGNOS DGPS

WAAS and EGNOS are two satellite based

DGPS systems. The correction signals are broadcast by satellites and are received by the 557/567’s standard GPS antenna. The accuracy of the corrected GPS position is typically better than 5 m (15 ft) for 95% of the time.

WAAS covers all of the USA and most of

Canada. EGNOS will cover most of Western Europe when it becomes operational.

Differential beacon DGPS

Differential beacons are land based radio

transmitters that broadcast correction signals that can be received by a special receiver on the boat. Dif ferential beacons are usually only installed near ports and important waterways, and each beacon has a limited range. The accuracy of the corrected GPS position is typically bet ter than 2 to 5 m (6 to 16 ft).

GPS receiver

Northstar GPS units have a sensitive 12-channel receiver, which tracks signals from all GPS satellites visible above the horizon and uses measurements from all satellites more than 5° above the horizon to calculate the position.

Each time a GPS receiver is turned on, it normally takes about 50 seconds before it outputs the first position. Under some circumstances it will take up to two minutes or longer.

10 Fuel functions and display

The Fuel functions require optional petrol/gasoline, diesel or SmartCraft™ fuel sensors to be installed and set up.

10-1 What the fuel compute r does

Each engine has a f low sensor installed to measure the engine’s fuel flow.

The 557/567 uses these flows, together with boat speed and engine RPM if available to estimate the fuel remaining in the tank(s), fuel used, range and fuel economy. This data is displayed on the fuel window (see section 10-2).

You c an:

display the fuel used during a trip

(see section 10-2)

set low fuel alarms (see section 10-4)

make fuel consumption curves - graphs

of fuel consumption and boat speed as a function of engine RPM - to monitor and optimise boat performance. (see section 10-6)

10-2 Fuel window

To go to the Fuel window, press , select More, then select Fuel.

The display differs according to the number of engines and tanks. If engine RPM is available and if you have made and selected a Fuel Consumption Cur ve (see section 10- 6), press to switch between a Summar y or a Fuel curve display.

The Fuel window sho ws

Speed

To select a bo at speed s ensor, see section 10-5-1.

RPM (if available)

If engine RPM is not available, the display shows depth.

Remaining

The fuel remaining in the tank(s) is shown as a vertical gauge on the right of the display. The height of the yellow bar(s) show how much fuel remains in the tank(s). If you have set a low fuel alarm (see section 10- 4), a red bar shows the level at which the alarm will trigger. If there are two tanks, the left bar shows the port tank, the right bar shows the starboard tank.

When you add or remove fuel, you must tell the 557/567, otherwise the fuel data will be meaningless.

A When you completely fill a tank

Go to the fuel window and press

Then:

On a single-tank boat, select Fill tank.

On a multi-tank boat, select Fill ta nk,

then selec t the tank you have filled.

Note: Underf loor fuel tanks are often dif ficult to refill to the same level twice, due to air pockets.

With underfloor fuel tanks:

Trim the boat to the same angle in the water

each time you follow procedure A .

Mostly use procedure B below when adding fuel, but completely fill the tank and follow procedure A about every tenth time you add fuel.

B When you partially fill a tank

1 Add fuel to a tank and write down how much

fuel you add.

2 From the Fuel window, press

select Add fuel.

3 On a multi-tank boat, select the tank that you

have added fuel to.

4 Change the number to the amount of fuel

that you added.

Note: If you follow procedure B ever y time you add fuel, then a small error will accumulate, because it is hard to measure exactly how much fuel you add. To avoid this, completely fill the tank and follow procedure A about every tenth time you add fuel.

C When you remove fuel

1 Before removing fuel, go to the Fuel window,

press

2 On a multi-tank boat, select the tank that you

10-5-1 Selectin g a boat speed sensor

The fuel calculations can use boat speeds from the GPS, or from a paddlewheel sensor or pitot sensor if these optional sensors are installed:

Paddlewheel and pitot sensors measure the

speed through the water; GPS speed is speed over ground; these sensors can give different values for Range, Economy and the fuel consumption curves (see section 10-5-2).

A pitot sensor is more accurate than a

paddlewheel sensor at high speeds but is not accurate at low speeds. A paddlewheel sensor is more accurate than a pitot sensor at low speeds.

Note: You can also use this procedure when you add fuel to a tank. In this case, add the fuel you have added to the amount of fuel originally in the tank to calculate the amount of fuel now in the tank.

When a low fuel alarm is set, the alarm’s fuel level is shown on the fuel window tank levels as a red bar. The alarm can also be set using the Alarms setup menu (see section 15-8)

10-5-2 Water speed and groun d speed

A paddlewheel sensor and a pitot sensor measure water speed, the boat speed through the water. A GPS measures ground speed, the boat speed over the bot tom of the water. If there is a current, then these speeds will be different, and the log, trip log, economy and range will be different, as shown below.

When the current is from ahead, ground sp eed is less than water speed

Water speed 10 knots

Water speed is better for measuring the boat’s potential performance, Ground speed is bet ter for going to a destination because it takes currents into account. To select a speed sensor, see section 10-5-1.

Water speed 10 knots

Current 4 knots

Gives a ground speed of 6 knots

For this example:

If the boat travels for one hour, uses 3 gallons of fuel per hour and has 50 gallons of fuel left:

Speed Log Economy Range

Using water speed: 10 knots 10 nm 3.3 nm / gal 165 nm

Using ground speed: 6 knots 6 nm 2.0 nm / gal 100 nm

When the current is from behind, ground speed i s more than water speed

Water speed 10 knots

Current

4 knots

Gives a ground speed of 14 knots

For this example:

If the boat travels for one hour, uses 3 gallons of fuel and has 50 gallons of fuel lef t:

Speed Log Economy Range

Using water speed: 10 knots 10 nm 3.3 nm / gal 165 nm

Using ground speed: 14 knots 14 nm 4.7 nm / gal 235 nm

10-6 Fuel consum ption curves

A fuel consumption curve shows fuel consumption (fuel used per unit of distance travelled) and boat speed as a function of engine RPM. Fuel consumption cur ves require engine RPM, which requires SmartCraft™ to be installed. Fuel consumption cur ves are powerful tools for assessing boat performance in different conditions and for helping you to run at the most economical speed and trim for the conditions.

10-6-1 Making a fuel co nsumption curve

To make a fuel consumption curve you will need to run the boat in a straight line for about 15 minutes using the engine’s full RPM range. For your first curve, choose a calm day with light wind and little current; have a typical load and a freshly cleaned hull. Later, you can make fuel consumption cur ves for different boat, weather or sea conditions. Compare these with your first cur ve to see how your boat’s per formance changes with conditions.

Making a curve

1 Start running the boat in a straight line.

2 Choose a speed source for the curve (see

section 10-5-1). Normally choose Water speed to measure the boat ’s potential per formance.

3 Press

4 Select Fuel consum ption cur ve, then

select New.

5 Enter the comfor table maximum RPM you

know you can achieve for the engine rather than the maker’s value.

6 The 557/567 then asks you to set the

minimum RPM. Set the throttle to idle; on a multi engine boat set all engines to about the same idle RPM. Now, do not change the engine speed. Wait for about 60 seconds for the boat to stabilise, then press . Wait while the fuel computer records the data.

twice, then select Fuel.

7 The 557/567 then asks you to set the throttle

to achieve a vessel RPM. On a multi engine boat set all engines to about the vessel RPM. When the engine RPMs are correct, the Vessel RPM box will turn green. Now, do not change the engine speed. Wait for about 60 seconds for the boat to stabilise, ensuring the Vessel RPM box stays green. Then press computer records the data.

8 The 557/567 repeats the above step to record

data up to the maximum RPM. Then the 557/567 asks if you want to save the curve. Select Yes. The fuel computer asks for a name for the curve. Change the def ault name if required. Then press . The 557/567 stores the new curve.

Note To interrupt making the curve at any time,

10-7 C ali brat ion

Calibrate petrol/gasoline fuel flow sensors during installation, or if the fuel readings seem inaccurate and the other troubleshooting suggestions do not help (see appendix B troubleshooting).

Note

SmartCraft™ fuel sensors are factory

calibrated and should never need recalibrating.

On a multi engine boat, calibrate each

engine’s sensor. This can be done at the same time with a portable tank for each engine or at different times using one portable tank.

Calibrating a sensor requires accurate

measurement of the fuel consumption. This is best done using a small por table tank. At least 4 gallons (15 litres) of fuel should be used to ensure an accurate calibration.

It is often very dif ficult to fill underf loor tanks

to the same level t wice due to air pockets, so the more fuel used, the more accurate the calibration.

To calibrate the sensor(s):

1 Record the level of the fuel in the tank(s).

2 Connect the portable tank(s) to the engine

through the fuel sensor(s).

3 Run the engine at normal cruising speed until

at least 4 gallons (15 litres) of fuel has been used per engine.

4 Check the actual amount of fuel used per

engine by refilling the por table tank(s) to the original level and noting the reading(s) of the fuel dispenser’s gauge.

5 Press

Setup engines.

6 On a single engine boat, select Calibrate

and change the displayed value to be equal to the reading of the fuel dispenser’s gauge, then press

On a multi-engine boat select the engine.

Select Calibrate and change the displayed value to be equal to the reading of the fuel dispenser’s gauge, then press Repeat for the other engines.

13 AIS

AIS is short for Automatic Identification System. The International Convention for Safety of Life At Sea (SOLAS) requires all vessels greater than 300 tons and all passenger vessels to be equipped with AIS Transponders. All vessels equipped with AIS permanently broadcast via one or more of the two dedicated VHF channels. This transmission may include information about the vessels MMSI number, its call sign, name, position, course, heading, speed, rate of turn and type of vessel.

This unit can receive and display AIS information when connected to an AIS receiver. Available AIS vessels transmitting in the local area are show on the chart when this feature is enabled.

Map datum

557/567 GPS positions are based on a worldwide reference (datum) known as WGS 84. Most paper charts are based on WGS 84. However, some paper char ts are based on other datums In these cases, the latitude and longitude coordinates of objects on the 557/567 chart window are different to the latitude and longitude coordinates of these objects on the paper chart. This applies to all objects, such as the boat, waypoints, tracks, lines of latitude and longitude and cartographic features such as land, rocks, buoys and depth contours.

Use

Map datu m to select the 557/567 map

datum to match the datum of the paper chart. Then, the latitude and longitude coordinates of object s displayed on the 557/567 will change to match the corresponding coordinates on the paper char t.

datum.

2 Select the map datum for the paper chart you

are using.

3 If you select a datum other than WGS 84 the

557/567 asks if you want to apply the NMEA datum offset (see below).

WARNING

When you change to a chart with a different datum, change the 557/567 map datum again.

Page 51

NMEA datum of fset

If you selec t a map datum other than WGS 84, the map datum of fset can be applied to latitude and longitude coordinates sent on the 557/567 NMEA output:

Latitude and longitude coordinates

displayed on any NMEA repeater do not match the coordinates on the 557/567. Latitude and longitude coordinates broadcast on any NMEA VHF transmitter will be the same as the coordinates on a WGS 84 chart.

Latitude and longitude coordinates displayed on any NMEA repeaters match the coordinates on the 557/567. However, latitude and longitude coordinates broadcast on any NMEA VHF transmitter will be slightly offset

from coordinates on a WGS 84 chart.

Map shif t

WARNING

Map shift is for eliminating minor offsets. It should not be used if the correct datum is available. Use map shift with caution: incorrect application will cause incorrect boat positions.

Some charts have consistent position errors. To correct this, apply a map shif t. After a map shift:

The positions of cartographic features (such

as land, rock s, buoys and depth contours) move on the 557/567 chart window to where they should be.

The positions of the boat, waypoints, track s,

and lines of latitude and longitude on the 557/567 chart window remain unchanged.

source connected via NavBus (see section 16- 8).

DGPS Source

Enables or disables the satellite based DGPS correction (see section 7). The options are or WAAS/EGNOS. Do not enable WAAS/EGNOS outside their coverage areas or the accurac y of the position might be degraded.

WAAS covers all of the USA and most of Canada. To use WAAS, the GPS antenna must have a clear view of the sk y towards the equator. EGNOS will cover most of Western Europe when it becomes operational.

None

Restart GPS

Restar ts the internal GPS receiver for servicing or troubleshooting. The GPS receiver takes up to three minutes to restart. The satellite window shows the status of the GPS receiver (see sec tion

7). Restart the GPS if the receiver has not been

used for some time and is taking a long time to get a GPS fix.

Static Navigation

When the boat stops or moves ver y slowly, the calculated GPS speed and course become erratic. Static navigation is a number, and the options are:

•

0.01 to 99.9:If the boat speed is slower

than this, the speed is displayed as zero and the course stays unchanged.

•

0(Off): The calculated speed and course

are always used.

Speed and Cou rse Filter

Waves and wind cause the boat speed and course to fluctuate slightly. To give stable readings, the 557/567 calculates these values by taking several measurements and averaging them.

A lower value averages measurements over

a shorter period of time. This gives the most accurate value but has the most fluctuations.

A higher value averages measurements over

a longer period of time. This gives the most stable value but will ignore some true speed changes.

Set the Speed and Course filters to the lowest values which give stable readings. The range of each filter is 1 to 60 seconds or Off (0).

For the selected engine, you can enter:

twice, then select

From tank: The fuel tank the engine is connected to.

Flow filter: Most engines do not draw fuel from the tank at a steady rate. To give a stable fuel flow reading, the 557/567 calculates the f low by taking several measurements and averaging them. Use the Flow filter to set the period over which the fuel flow is averaged.

The Flow filter can be set from 0 to 30 seconds. Use the lowest value which gives a stable f low. Usually a value of 5 to 10 seconds will give a satisfac tory result for two-stroke carburettor engines. Fuel injected or four-stroke engines may require a larger value.

This setting affects the Fuel flow and Fuel economy reading on the Fuel window but it does not affect the Fuel used reading.

Press twice, then select Calibrate:

Speed

This calibrates the speed from a paddlewheel sensor connected to the Instrument. Calibration may be required because different hull shapes have different flow characteristics. Obtain an accurate measurement of the boat’s speed from a GPS receiver; or by following another boat travelling at a known speed; or by making a timed run over a known distance.

Note: for accurate calibration:

• The speed from a GPS receiver should be greater than 5 knots.

• The speed from another paddlewheel transducer should be between 5 and 20 knots.

• Best results are achieved in calm conditions where there is minimal current (best at high or low tide).

or to change the displayed speed

to the true value.

Speed filter

Waves and wind cause the boat speed from the paddlewheel transducer to fluctuate slightly. To give stable readings, the Instrument calculates these values by taking several measurements and averaging them. Set the Speed filter to the lowest value which gives stable readings. The range is 1 to 30 seconds or Off (0).

Temperature

The factory settings should be sufficiently accurate for normal usage. To calibrate the temperature readout, first measure the water temperature with a thermometer known to be accurate.

Use the cursor keys to display the temperature readout box, then increase or decrease the value to match the measured temperature. The temperature can be set from 32° to 99.9°F (0° to

37.7°C) with a resolution of 0.1° unit.

To change the units between °F (Fahrenheit) or °C (Celsius), see section 15-9.

Temperature filter

Water turbulence and currents cause the water temperature to fluctuate slightly. To give stable readings, the Instrument calculates these values by taking several measurements and averaging them. Set the Temperature filter to the lowest value which gives stable readings. The range is 1 to 30 seconds or Off (0).

Keel Offset

A depth transducer measures depths below where the transducer is mounted on the boat, usually the bottom of the boat. The Instrument calculates the depths to display by adding the keel offset to all measured depths.

A Have a zero keel offset to display depths

below the transducer.

B Enter a positive keel offset to increase the

displayed depth. For example to display the total depths below the surface, enter the depth of the transducer below the surface.

C Enter a negative keel offset to decrease the

displayed depth. For example, to display the depths of clear water below the boat, enter minus the depth of the deepest part of the boat below the transducer.

16-5 Installation: GPS a ntenna

Selecting an antenna

Fit one of these GPS antennas:

• Normally use the GPS antenna supplied.

• An optional differential beacon DGPS antenna

to give enhanced accuracy within range of land based differential beacons in areas where WAAS or EGNOS are not available. Such a DGPS antenna has both a GPS receiver and a beacon receiver, and it automatically applies the beacon correction to the GPS position.

• A compatible GPS or DGPS instrument or

antenna connected by NavBus (see section 16-8) or NMEA (see section 16-9). In this case, the 557/567 does not need its own antenna.

Note:

• To configure the 557/567 for different antenna options, see section 16-5.

For more information, contact your Northstar dealer.

DGPS Source:

Enables or disables the satellite based DGPS correction (see section 7). The options are None or WAAS/EGNOS. Do not Enable WAAS/EGNOS outside their coverage areas or the accuracy of the position might be degraded.

WAAS covers all of the USA and most of Canada. To use WAAS, the GPS antenna must have a clear view of the sky towards the equator. EGNOS will cover most of Western Europe.

Restart GPS:

Restarts the GPS receiver, satellite reception will be lost until the receiver completes its restart and acquires the satellites.

Select restart GPS and press

b You added or removed fuel but did not tell

the 557/567 (see section 10-3).

c The fuel tank may not refill to the same

capacity each time due to air pockets. This is a particular problem with underfloor tanks.

b With WAAS/EGNOS: Boat out of coverage

area (see sec tion 7).

c With WAAS: GPS antenna does not have a

clear view of the horizon towards the equator.

b With beacon DGPS: boat out of range of a

DGPS beacon.

3-4 Erratic fuel flow readings:

a The Flow filter value is not suitable for the

engine. Check that the value is not set to zero, then try increasing the value until a steady flow rate is shown (see section 15-4).

b The fuel flow sensor(s) may be too close to

the fuel pump or may be subject to excessive vibration. Refer to the fuel sensor installation manual.

c Check for leaks in the fuel line or in the fuel

pickup in the tank.

3-5 There is no reading for fuel economy:

a The boat must be travelling through the

water to have a reading.

b If you selected a paddlewheel sensor (see

section 10-5-1), check that the paddlewheel spins freely.

Glossary

Attenti on Area - An important area on a chart, such as a restric ted anchorage or a shallow area (see section 15-2).

AIS - Automatic Identification System. A System where vessel information (location, course, speed, etc.) is broadcast by VHF radio, for use by other vessels in navigation and collision avoidance.

Bathymetric line - A depth contour line on the chart.

Chart card - A plug-in card that stores chart data for a region (see section 1-3).

C-MAP™ char t card - See Chart card.

C-MAP™ user card - See User card.

CPA - Closest Point of Approach. The closest

distance two vessels will come to each other based on their current course and speed.

Cursor - A 3-2).

DGPS - Differential Global Positioning System. A navigation tool based on GPS with some errors corrected (see section 7).

DSC - Digital Selective Calling. A feature of marine radios enabling communication between specific vessels, as well as distress alerts.

Goto - A simple way of navigating straight to a waypoint or to the cursor position (see section 3-1).

GPS - Global Positioning System. A satellite based navigation tool (see section 7).

Leg - The straight segments of a route between waypoints. A route with four waypoints has three legs.

symbol on the display (see section

MMSI - Maritime Mobile Service Identity. Unique identification number for a vessel, for use in Digital Selective Calling.

MOB - Man overboard.

MOB function - Starts navigating back to the

place where someone fell overboard (see sec tion 2-5).

NavBus - A way of connecting Northstar instruments together to share data (see section 16-8).

NMEA - National Marine Electronics Association.

NMEA 0183 - A standard for interfacing marine

electronic devices (see sec tion 16-10).

Route - Two or more waypoints linked in sequence to form a course for the boat (see section 6).

SmartCraft - A feature of Mercury Marine engines for monitoring engine performance.

TCPA - Time to Closest Point of Approach. Time until the closest point of approach for two vessels.

User card - A plug-in card that stores waypoints, routes and tracks (see section 12).

UTC - Universal Time Coordinated or Coordinated Universal Time, which is a standard world time, formerly called Greenwich Mean Time (GMT).

VHF - Very High Frequency. The frequency range used by marine radios.

Waypoint - A position that you can set on the 557/567 chart, for example a fishing spot or a point on a route (see section 5).

Navigation data

BRG Bearing to Destination: Bearing to the destination from the boat.

BRG Bearing to cursor: Bearing to cursor from boat (cursor mode, see section 3-2)

CDI Course Deviation Indicator: When the boat is navigating to a point, the chart and highway

windows show a parallel line on either side of the plotted course. These two lines are called the Course Deviation Indicator (CDI) lines . The distance from the plotted course to a CDI line is the CDI scale.

Set the CDI scale (see section 15-2) to the maximum distance that the boat should deviate

from the plotted course. The chart and highway windows show the CDI lines, which are like a highway over the water where t he boat will move. The windows show ho w far the boat has deviated f rom the plotted cour se and if the boat is app roaching a CDI line. If the XTE alarm is enabled (see section 15-7) an alarm will sound if the boat reaches a CDI line.

COG Course Over Ground: Direction in which the boat is moving over the ground.

CTS Course To Steer: Optimum course to steer to return to the plotted course.

DTG Distance To Go: Distance from the boat to the destination.

ETA Expected Time of Arrival: At the destination, assuming that SOG and COG remain constant.

RNG Range to cursor: Distance from boat to cursor (cursor mode, see sec tion 3-2)

SOG Speed O ver Ground: Current b oat speed over the gro und. This is not necess arily the same as

the boat speed through the water nor the speed at which it is approaching the destination.

STR Steering: The diﬀ erence between COG and CTS.

TTG Time To Go: The estimated time to reach the destination.

XTE Cross Track Error: The distance from the boat to the nearest p oint of the plotted course. XTE

may have a lette r: R means steer to the right to return to th e plotted course, L m eans steer to the left.

VMG Velocit y Made Good: The speed at which the boat is approaching the destination.
