Safety notices
CAUTION
WARNING
Navionics CF Card Reader
Navigation aid
When this product is used within a navigation system, it is
only an aid to navigation. It’s accuracy can be affected by
many factors, including equipment failure or defects, environmental conditions and improper use or handling. It is
the user’s responsibility to exercise common prudence
and navigational judgements. This product should not be
relied upon as a substitute for such prudence and judgement. Always maintain a permanent watch so that you can
respond to situations as they develop.
WARNING
The Navionics CF card reader has been designed and
tested for home and dockside planning use only and has
not been tested to marine standards for ruggedness or
interference with other devices on board the vessel.
Raymarine cannot accept responsibility or liability for any
damage to the card reader, associated systems and equipment or compatibility issues arising from its use while
underway.
Intended use
RayTech V6.2 is intended for recreational marine use. Users should note that
only authorized government charts and associated Notices to Mariners
contain all the information required for safe navigation
Product installation
Disclaimers
This equipment must be installed and operated in accordance with the Raymarine instructions provided within
this guide. Failure to do so could result in poor product
performance, personal injury, and/or damage to your boat.
This electronic chart is an aid to navigation designed to facilitate the use of
authorized government charts, not to replace them. Only official government
charts and notices to mariners contain all of the current information needed
for the safety of navigation, and the Captain is responsible for their prudent
use.

RayTech RNS V6.2 - User’s Guide
This program and its charts do not excuse the user from carrying the required
official charts and documents.
Raymarine does not warrant that this product is error free or that it is
compatible with products manufactured by any person or entity other than
Raymarine.
This product utilizes digital chart data, and electronic information from the
Global Positioning System (GPS) and weather information which may contain
errors. Raymarine does not warrant the accuracy of such information and you
are advised that errors in such information may cause the product to
malfunction or give incorrect readings. Raymarine is not responsible for
damages or injuries caused by your use or inability to use the product, by the
interaction of the product with products manufactured by others, or by errors
in chart data or information utilized by the product provided by third parties.
Except for the limited warranty regarding the magnetic media contained in
the license agreement accompanying the product, this product is provided
‘AS IS’ without warranty of any kind, either express or implied, including but
not limited to the implied warranties of merchantability and fitness for a
particular purpose, and any others which may arise from course of
performance, course of dealing, or usage of trade.
Like all systems it is not perfect and any part of it can fail. GPS accuracy varies
between 2 and 50 meters.
NMEA 0183 1.0 / 1.5 only supports 2 digits of latitude and longitude, giving a
precision of approximately 60 feet.
NMEA 2.0 / 2.1 supports 3 digits of latitude and longitude, giving a precision
of approximately 6 feet.
Another limitation to the system accuracy is digital charts. These electronic
charts are made by highly skilled cartographers. Surveys on which the
cartography is based, were in some cases, made over 50 years ago. So
despite everyone’s best efforts, it may be possible to have errors in the final
product.
Lastly, RayTech software was developed by highly skilled and talented
software engineers and underwent a rigorous test and quality assurance
program before being released. However, it is possible that software issues or
malfunctions may remain undetected in the software. While Raymarine make
every effort to find, fix and repair software issues as they are discovered, this
product is specifically not promised to be issue free.
The limits of electronic navigation
This manual describes how to install and operate RayTech V6.2 marine
navigation software. It assumes that the personal computer (PC) on which
the software is to be installed meets the requirements for running this version
of RayTech, and that all peripheral equipment intended to be operated with it
is compatible and has been correctly installed.
This manual is intended for users with varying technical and
marine abilities, but assumes a general level of knowledge of
PC use and nautical terminology and practices.
This manual gives an overview of RayTech V6.2, and details the main
functions and how to operate them. There are several ways that a task can be
Experienced navigators know not to rely on a single method of navigation for
determining their position. Two or more methods should be used to
determine position and guard against errors placing you or your boat in a
dangerous position. Global Positioning System (GPS) based electronic
navigation is an amazing application of technology, but like all other
technology, has limits. A wise navigator will understand these limits and how
they affect the safety of their boat and crew.
The Global Positioning System is made up of components starting with
ground based computers to monitor and maintain the system made up of 24
satellites in orbit around the earth. The system ends at your boat’s receiver.

3.7 Installing charts
This section deals with installing the different types of charts that are
compatible with RayTech.
C-MapNT+/PC charts from CD-ROM
IMPORTANT - RayTech must be exited and re-opened before attempting
to install C-Map NT+/PC Selector program. Failure to do so will prevent
your RayTech software from being able to find installed C-Map charts.
To install C-Map charts from a CD-ROM it is necessary to install the C-Map
NT+/PC Chart Selector software onto your PC. This must be installed in
accordance with the instructions on the C-Map software.
Chapter 3: Getting started
Using the C-Map NT+/PC chart selector you select the charts that you want
to install. You then purchase the relevant chart licences on-line and register
them. They are automatically detected by RayTech on start up and are
made available to the RayTech program. C-Map charts are not installed
using the RayTech chart installer.
Note: Raytech will only work with the E86008 C-Map USB C-Card reader
and not later models. This product is now discontinued.
C-Map USB C-Card reader
The USB C-Card Reader must be installed on your PC before you start
RayTech software. Failure to do so will prevent RayTech from being able to
access C-Map charts on C-cards or waypoints or routes that are stored on
the User card.
Charts inserted in the USB C-Card Reader are read in real time as long as
the card is actually inserted in the card reader. C-Map charts cannot be
downloaded to your PC for off-line viewing.
Maptech cartography
Maptech BSB V4.0 cartography
You should install and register Maptech BSB V4.0 cartography in accordance with the installation instructions contained on their software. Failure
to follow the instructions will prevent charts being installed by RayTech.
Earlier Maptech BSB cartography versions.
Versions of Maptech BSB cartography prior to V4.0 do not need to be registered prior to installation using the RayTech chart installer.
25
Navionics cartography
There are two ways in which Navionics cartography can be accessed by
RayTech:

card installed in a Raymarine multifunction display, open either a new 2D
or 3D chart page. Navionics cartography can then be used with RayTech
acting as a repeater display.
Navionics multicard reader
The Navionics USB multicard reader must be installed on your PC before
you start RayTech software. Failure to do so will prevent RayTech from
being able to access Navionics charts on CF cards or waypoints or routes
that are stored on the User card.
With a Navionics chart card reader installed on the PC that is being used to
operate RayTech, and a Navionics chart card installed you can access Navionics charts.
Charts inserted in the Navionics USB multicard reader are read in real time
as long as the card is actually inserted in the card reader. Navionics charts
cannot be downloaded to your PC for off-line viewing.
RayTech chart installer
The RayTech chart installer is used for installing BSB formatted, raster,
MapTech PCX, photo and topographic charts. It will search and locate
charts that are installed on your system or a CD-ROM. To install charts

Chapter 5: Using charts
5.1 Introduction
RayTech utilizes chart layering technology, which permits you to simultaneously view different types of charts and maps, including navigational
charts, live radar, aerial photographs and weather data.
For full information on installing charts refer to Chapter 2 - Getting Started.
Use your charts safely
CAUTION: RayTech should not be used as a substitute for good
navigational practice nor for official government charts.
Until you are familiar with interpreting the chart display, you should take
every opportunity to compare displayed objects with visual targets, such as
buoys and coastal structures. You should practice harbor and coastal navigation during daylight and in clear weather conditions. RayTech simulator
mode will also help you gain experience.
When connected to a heading data source you can also overlay the radar
image on to the chart.
5.3 Opening a chart
To open a chart for the first time:
1. Click File/Open New Page. The open new page dialog box is
displayed.
5.2 The chart screen
The amount of detail shown varies for different chart types and areas
covered. The scale at which the chart is shown also affects the amount of
detail shown. Cartographic information is also available for objects marked
on the chart. Source details for such objects as structures, lines and open
sea areas are also available. Using the advanced functions described in
Chapter 7 - Using RayTech’s Advanced features, information on the
weather, tides and currents can be overlaid on the charts.
D875

displayed. Select Range In or Range Out.
Your boat is displayed using a boat shaped icon.
To find your current position on the chart:
Click Find Vessel in the standard toolbar, or the Find vessel soft key.
The page or pane will automatically pan and the boat’s position will be
centered on the screen.
The page or pane will remain centered until you click the screen. The chart
will then re-center on the cursor’s location.
5.5 Choosing a chart type
You choose the type of chart you want to display using the charting
toolbar.
There are four primary buttons on the toolbar for controlling the type of
chart being displayed. These are:
• Raster charts.
• Vector (Navionics or C-Map).
• PhotoCharts Overlay (Navionics or raster).
• Topo Charts.
There is also a button to enable or disable radar overlay, and a button to
enable or disable chart quilting.
Note: RayTech will use raster photos over Navionics photos when both
layers have been turned on.
Chapter 5: Using charts

chart layer, try switching off all of the other layers on the charting toolbar
until the background appears aquamarine. Then click the button of the
chart type you want to view, and the cartography will appear.
Chart quilting
When you are working with raster format navigation charts, the Quilting
button allows you the option of using a single chart image, or seamless
charting.
With quilting enabled, the system default for any opened chart window,
RayTech stitches together all of your raster cartography, connecting the
edges of the different charts together. This means that no manual intervention is required to switch charts. You simply pan to the area you wish to
see. Chart detail will be affected as you range in or out to view larger or
smaller scales.
When you are using the quilting function, the best available chart for the
area you are in will always be displayed. This information is based on your
boat’s position, the focal point of the cursor and the range scale selected.
As you pan or zoom around the chart, cartography will be continuously
displayed.
With quilting turned off, the chart at the focus of the display will be shown
alone. The scanned edges of the chart containing the latitude and longi-
tude scales, notes and chart numbers will become visible and all adjacent
charts will be hidden from view. Zooming in or out will cause the chart to
be enlarged or reduced in size.

Changing your viewpoint
Making the view clearer
There are two ways in which you can make your chart view clearer:
Softkeys
You can change your view of the chart using the following softkeys:
•
•
•
•
Rotate On - enables you to choose which point on the screen the
chart will move around.
• Eye - rotates the chart around the eye-point, maintaining a relative position to the on-screen boat.
• Center - rotates the chart around the center-of-view on the chart.
Adjust - enables you to choose how you change the view.
• Rotate - enables you to rotate the chart view through 360o. If you
want to maintain a view from a particular angle, rotate the chart
until you see the required view. The chart will automatically
update.
• Pitch - enables you to change the angle at which you view the
chart. This can be from sea level to a full aerial view. You cannot
view the chart from underwater.
Find Ship - pressing this soft key at any time enables you to return to
the default action motion mode chart view.
Presentation - enables you to view additional features.
Chart offset
The 3D chart center can be offset in a similar way to a 2D chart. You can
offset the position of the on-screen boat by 1/3 or 2/3 from the center-ofview towards the edge of the window. This has the effect of making more
of the 3D chart visible without changing the selected range.
•
•
Exaggeration.
Declutter.
Exaggeration
Sometimes it is easier to see a topographic feature on the chart by making
it more obvious., for example, this could be particularly helpful while
fishing.
Using the exaggeration feature of the 3D chart to vertically stretch objects
on the chart can achieve this making it easier to see an objects shape and
position. You can exaggerate the chart between a factor of 1 and 50 using
the Adjust Exaggeration soft key.
Declutter
Navigating in an area that shows a lot of information on the chart, such as
navigation marks, can be confusing. Depending on your chart view level it
can make features or even your own position difficult to see. The declutter
feature helps to reduce this confusion and make the chart clearer, by
removing some objects from view.
Planning mode
Planning mode enables you to view an area of the chart, different to the
one in which you are navigating. To enter planning mode, pan to the area
of the chart that you want to view. Using the right-mouse menu select,
Move Boat here. Active motion mode is automatically suspended.
All of the functions that are available in active motion mode are available
in planning mode and control of the chart is the same. However, the mode
Chapter 6: Using Platinum cartography
information in the status bar is now shown in brackets to indicate planning
mode has ben selected.
Clicking the FIND SHIP soft key reTurns the application to active motion
mode, in the default view, showing the chart in the forward looking view
at your current position.
Using 2D and 3D charts together
If the area in which you are navigating is unfamiliar to you, or visibility is
poor, working with 2D and 3D chart applications on the screen side by side
can give you extra confidence and help you to find out what is around you.
With your RayTech page set up to view the two applications together a
comprehensive view of the surrounding area is show.
As with all multiple page sets the active window is indicated by a red
border. To make any changes in an application it must be the active
window.
Navigating with 3D Charts
To navigate to a new waypoint or use a new route, you should first create
the waypoint or route on your 2D chart.
Once navigation is activated in the normal way, the 3D chart displays:
• The active waypoint using the same symbol as the 2D chart.
However, it should be remembered that a route can only be edited using a
2D chart. Any changes that you make on the 2D chart are automatically
shown on the 3D chart.

Chapter 7: Working with waypoints
7.1 Introduction
Waypoints are a core feature of RayTech. They can be created while any
application is active and used by the others. They can be stored in the
system, e-mailed, archived to a memory card, or transferred to other
SeaTalk, SeaTalkhs, or NMEA compatible instrument.
2. Move the cursor to where you want to place the waypoint.
3. Click and a new waypoint will appear in the selected position.
7.2 What is a waypoint?
To place a waypoint at the boat’s current position:
1. Select Waypoint/Place Waypoint at Vessel.
2. A new waypoint will be placed at the boat’s current position.
A waypoint is a position marked on a chart, radar or sonar screen as a
reference point or as a place to go. Waypoints are represented on screen by
a symbol and their details stored in a dedicated waypoints list.
7.3 Placing a waypoint
A waypoint can be placed:
• at the cursor position
• at the boat’s position.
• at a known position.
All waypoints can be used in creating routes. When waypoints are placed
they are given a default symbol, you can change this default if required refer to “Changing a waypoint symbol” on page 53.
Note: When using RayTech as part of an integrated system, waypoints
should be named in accordance with the parameters set by your
GPS/chartplotter display.
...at the cursor’s current position
To place a waypoint at the cursor’s current position:
1. Select Waypoint/Place Waypoint at Cursor.
... at the boat’s current position

Chapter 8: Working with routes
8.1 Introduction
This chapter explains how to use RayTech to chart and plot courses. It is
intended to have you navigating in the shortest time possible and covers:
you can create several back-up routes for any destination, should inclement
weather or other circumstances dictate you take a different course.
• Creating routes.
• Editing routes.
• Monitoring a course.
The definition of terms used in working with charts and routes will be
found in Appendix A - Charts.
If you have RayTech connected to your GPS and autopilot, the route you
chart on the screen can be run automatically.
A route is a path from location A to location B, and is composed of a series
of waypoints that you place on a displayed chart. Each waypoint represents
a certain position along the path of a route. A route typically has a starting
waypoint, an ending waypoint, and as many intermediate waypoints as
you need or want.
The imaginary line between two waypoints is known as a leg. The leg of a
route that your boat is currently traveling is called the active leg. An active
leg consists of an origin waypoint (the waypoint that you have just
departed) and a destination waypoint (the waypoint you are moving
towards). In RayTech, the active leg of a route is represented by a dashed
line, and the destination waypoint blinking.
Plotting a route can be achieved with just a few mouse clicks and you can
easily edit the route after placing it on screen. Routes can be as simple or
as complex as you need, and customized for easy recognition and navigation. RayTech stores all of your favorite or most commonly used routes, and
You create a route by placing a series of waypoints between your starting
point and your destination. Each waypoint represents a certain position
along the path of a route.
Note: When using RayTech as part of an integrated system, routes should
be named and the number of waypoints used should be in accordance with the parameters set by your GPS/chartplotter display.
To create a route:
1. Click Route. The route softkeys are displayed.
2. Click Create Route. The Quick route dialog box is displayed.

With RayTech receiving accurate heading and position information, you
can use the Course Deviation Indicator (CDI) - see “CDI monitor” on
page 66 to monitor your course and accurately steer to a target waypoint.
The CDI gives a graphical representation of your boat’s course in a ‘rolling
road’ format.The symbol for your boat is shown on the centerline when the
boat is on course, with steering instructions for maintaining your course
shown just above the screen horizon.
As you travel towards the target waypoint, the grid representing the sea,
will move down the screen at a rate proportional to your boat’s speed.
Your target waypoint is located on the centerline of the display over the
screen horizon. As the distance to the target waypoint decreases, the
waypoint symbol will appear on the horizon and start to move down the
screen. The waypoint symbol will blink on and off and it’s name is
displayed to the right as it travels down the screen. Information on your
boat’s course is displayed above the screen horizon to indicate:
•
•
Target - waypoint name.
Speed Over Ground (SOG) - displayed in knot.
Chapter 8: Working with routes
• Range to target waypoint - displayed in nautical miles (nm).
• Course Over Ground (COG) - displayed in degrees magnetic.
• Bearing to target waypoint - displayed in degrees magnetic.
• Cross Track Error (XTE) - displayed in nm.
The XTE also gives instructions as to which way you should steer to correct
the error. These instructions are shown as arrows either side of the XTE
pointing towards the centerline. The greater the XTE, the more arrows are
shown. You should correct your course by steering in the direction indicated by the arrows.
The CDI can be displayed on its own page or as part of a custom page with
other applications. MARPA targets can also be displayed on a CDI page.
Restart XTE
CDI’s Restart XTE function gives you the option, if selected to re-center the
boat within the CDI window, zeroing all the XTE data.
Next Leg and Previous Leg
Next Leg and Previous Leg are functions available to allow you to select the
waypoint (within a route) you are aiming at while completing a ‘GOTO’. By
selecting the ‘Next Leg’ you select the next waypoint in the route you
have selected. By selecting ‘Previous Leg’ you revert to a previous
waypoint in the selected route.

Chapter 9: Using tides and currents
CAUTION: Tides and currents
Whilst every effort is made to ensure the accuracy of the
data used for tides and currents, this information can be
influenced by local conditions. It is therefore recommended
that consideration is given to obtaining accurate local information wherever possible
9.1 Introduction
To set the tide region:
1. Select File/New Page/Tides. A new page will open showing the
default tide information.
2. Click Presentation.
3. Click Region. The region dialog box is displayed.
Note: If you do not set your preferred region the tide and current information will default to the United States (US) region.
Tide and current data is available for many areas on the chart application
of RayTech.
The predictions displayed for Tides and Currents are sufficiently accurate
under moderate weather conditions, for the coastal areas served by the
reference station, to be used for navigation planning. However, certain
weather fronts and storms can alter tidal patterns and influence predicted
times and heights.
In addition and in common with all similar products, tidal data is calculated
algorithmically and may, in some regions, be subject to error. If exact tidal
heights or times are critical to a particular passage, Raymarine recommends that details are checked against a Tidal Almanac published by the
appropriate marine authority.
Note: RayTech uses your PC or laptop’s system clock for the date and time
associated with displaying tide or current data.
Setting the region
To make sure that the correct tide and current information is displayed, you
must set the region in which you are operating.
4. Scroll and highlight the required area. Click OK. The area is now set to
that selected.
5. Repeat Steps 1 through 4 replacing Tides with Currents to set the
correct region.

• Getting the best radar picture.
• Using waypoints to mark position.
• Collision avoidance using VRM/EBLs and MARPA.
• Overlaying a radar image on a chart.
For technical information on radar refer to Appendix B -Radar.
With your radar scanner connected and the radar in transmit mode, the
radar picture provides a map-like representation of the area in which the
radar is operating.
network that includes a compatible Raymarine radar scanner AND a
compatible Raymarine multifunctional display. The multifunction
display must be designated as the data master.
Full functionality of the radar application requires heading and position
data. A fast heading sensor is also needed for operating the Mini Automatic Radar Plotting Aid (MARPA) functions and radar/chart overlay.
Until you are familiar with interpreting the radar display, you should take
every opportunity to compare the radar’s display patterns with visual
targets such as other boats, buoys, and coastal structures. You should practice harbor and coastal navigation during daylight and in clear weather
conditions.
Typically your boat’s position is at the center of the display, and its dead
ahead bearing is indicated by a heading line, known as the Ship’s Heading
Marker (SHM).
On-screen targets may be large, small, bright or faint, dependent upon the
size of the object, its orientation and surface. Be aware that the size of a
target on-screen is dependent on many factors and may not necessarily be
proportional to its physical size. Nearby objects may appear to be the same
size as distant, larger objects. With experience, the approximate size of
different objects can be determined by the relative size and brightness of
the echoes.

Course - up (C-UP)
Gain
In this mode the radar picture is stabilized and shown with your current
course upwards. As your boat’s heading changes, the SHM moves accordingly.This mode requires heading data input.
The effects of false echoes and clutter can be reduced by using the GAIN
soft key and its associated controls to make the overall picture clearer. The
AUTO settings usually give the best results although you can adjust these
settings if required.
North - up (N-UP)
If you select a new course, the picture will reset to display the new course
upwards.
The reference used for Course-up depends upon the information available
from the following:
•
•
•
Bearing from origin to destination, i.e. intended course. Used if a
FOLLOW or GOTO is active.
Locked heading from an autopilot. Used if autopilot is engaged, but no
FOLLOW or GOTO is active.
Instantaneous heading. Used if neither of the above is valid, the
system now reassesses the course every 5o.

4. When you have finished, click the BACK button.
FTC
You can use the Fast Time Constant (FTC) function to remove areas of
clutter at a distance from your boat. It should be used in conjunction with
the RAIN function to obtain the best results.
When the FTC function is turned up, only the leading edge of large (rain
clutter) echoes is shown, while the effect on smaller (boat) echoes is slight.
This means that you can also use the function on shorter ranges to distinguish between two very close echoes on the same bearing, which may
otherwise merge and appear as one echo.
With the FTC function set high, the receiver is made less sensitive, and
there is a reduction of background noise and fill-in reTurns from land and
large targets. You should therefore set the control to low (or Off) when its
use is not required.
Rain mode
Your radar can see echoes from rain and snow. These reTurns from storm
areas and rain squalls consist of countless small echoes that continuously
change size, intensity and position.
You should use the rain function to reduce large clutter masses from these
reTurns around your boat
Sea mode
The sea clutter control reduces the gain level in the area near your boat,
extending for 3 to 5 nm depending on the wave and sea conditions. This
reduces sea echoes to intermittent small dots, while small targets remain
visible. Gain levels further from your boat are unchanged.
73
The sea clutter control can be set to Auto-Harbor (default), Auto-Offshore,
or manual mode. In Auto-Off-shore mode, the radar optimizes its settings
to account for the effects of sea clutter. In harbors and close proximity to
land, different auto settings may be necessary to account for land clutter.
To avoid losing small targets, set the sea clutter control to Auto-Harbor
mode. If you set the sea control to manual mode, be sure you adjust the
settings to ensure that all close small targets are visible.
Gain mode
The gain control adjusts the level of the display of signals received from the
scanner; and is the equivalent to the volume control on a radio. The gain
control can be set in either Auto or Manual mode.
In auto mode, the radar self optimizes its settings. In harbors or close proximity to land, different auto settings may be necessary to compensate for
the effects of land clutter.
In manual mode, you must adjust the settings to ensure that all close small
targets are visible, and you should check it every time you change the
range scale. On long range settings, the gain should be set to give a slight
speckle in the background of the radar picture. On shorter ranges, you may
want to reduce the gain slightly to reduce the speckle and improve target
definition. Do not set the gain too low, or you may miss small or weak
targets. The gain mode and its associated settings are retained each time
you turn the radar off.
Tune
You can use the tune control to fine-tune the receiver in the radar’s scanner
to yield maximum target reTurns on the display.
In Auto mode, the radar tunes itself automatically on all range scales. If
you decide to use manual fine-tuning, adjust it about 10 minutes after you

sion is available. Target expansion overrides the normal pulse length,
thereby increasing the size of the target seen on the screen; however, this
is at the expense of range resolution.
Note: It is recommended that you leave the tune function in AUTO mode, to
ensure that the radar receiver is always tuned to receive the maximum signal.

10.7 Setting up the radar display
Range control enables the radar picture to be viewed at varying scales. This
is also known as ‘zooming’ in or out. The shortest range scale gives a
maximum range of 1/8 nm, measured from the center to the top of the
radar picture. The longest range scale gives a maximum range of between
24 and 72 nm, depending upon your scanner type.
Short range scales
The short range scales provide greater detail of the radar echoes close to
your boat, and should be used as you approach coastlines, harbors or other
boats in the area.
Long range scales
The long range scales provide the best overview of your boat’s relationship
to landmasses, weather fronts, and large ship targets, in or beyond view.

VRMs/EBLs.
A variable range marker (VRM) and its associated electronic bearing line
(EBL) is used to determine the range and bearing (respectively) of objects
detected by the radar.
EBL
A standard VRM is displayed as a circle with its center on your boat’s position, and its EBL is displayed as a line from the origin, to the edge of the
radar screen. Both are shown as dotted lines. If you range in or out, or
offset the center of the display, the original setting of the VRM/EBL remains
unchanged. RayTech allows two VRMs/EBLs to be displayed at the same
time.
When a VRM/EBL pair is active, their bearing and range can be displayed in
an associated databox. This is displayed by clicking the VRM/EBL Box soft
key to ON.
VRM
D6990_1
To measure the range and/or bearing of a target
or point from your boat’s position, you need to
display a VRM/EBL and edit (move) it on- screen
so that it intersects the desired target or point.
The first VRM/EBL will be placed at a location 1/3 of the current range and
0300 relative to your boat’s head. If this setting is adjusted, the display will
retain the adjustments and use them when the VRM/EBL is next turned on.

Using VRM/EBLs
To use a VRM/EBL to tell you how far away a target is and in
what direction it is traveling:
1. Click the VRM/EBL soft key. The soft key options for VRM/EBL 1 will
be displayed.
2. Click the VRM/EBL 1 soft key to ON. The VRM/EBL will be shown on
the radar picture with your boat at its center.
3. Click the Adjust VRM 1 soft key. The on-screen VRM will change from
a dotted to a solid line.
4. Use the cursor to adjust the VRM to its required size.
5. Click to return the VRM to a dotted line and retain the adjustment.

8. Click to return the EBL to a dotted line and retain the adjustment.
Guard zones
Note: When using a VRM/EBL, you may want to turn off the range rings to
make the VRM/EBL easier to see.
Guard zones enable you to set up one or two sector or 360o zones around
your boat. Any target entering this zoned area will cause a guard alarm to
sound.
D6992_1
Guard zones are fixed with respect to the ship’s heading marker (SHM,
moving as the SHM moves. They also move if you offset the center, or if
you change the range scale, so that the area you have marked is maintained. However, a guard zone only operates when the whole zone is
displayed on the screen, or could be displayed by off-setting the center. In
addition, a guard zone is inactive for 10 seconds after it is placed or resized, to avoid inappropriate alarms during positioning.
The distance and bearing of the target is now shown in the VRM/EBL
databox. You will be able to tell in which direction the target is traveling by
watching how it moves in relation to the EBL. If it continues to travel
directly along the EBL, it indicates that it is on a possible collision course
with your boat - take the appropriate action.

CAUTION: MARPA can improve collision avoidance when used
wisely. It is the user’s responsibility to exercise common
prudence and navigational judgement.
There are conditions where acquiring a target may become difficult. These
same conditions may be a factor in successfully tracking a target. Some of
these conditions are:
•
The target echo is weak. The target is very close to land, buoys or other
large targets.
• The target or your own boat is making rapid maneuvers.
• Choppy sea state conditions exist and the target is buried in excessive
sea clutter or in deep swells.
• Choppy sea state conditions exist yielding poor stability; own boat’s
heading data is very unstable.
• Inadequate heading data.
Symptoms of such conditions are that acquisition is difficult, and the
MARPA vectors are unstable; the symbol wanders away from the target,
locks on to another target or changes to a lost target symbol.
If any of these conditions are present, acquisition and tracking may need to
be re-initiated or, in some cases be impossible to maintain. Improving the
quality of the heading data will reduce the effect of the other conditions.
What is MARPA?
You can use the Mini Automatic Radar Plotting Aid (MARPA) functions for
target tracking and risk analysis. MARPA improves collision avoidance by
obtaining detailed information for up to 10 automatically tracked targets
and provides continuous, accurate and rapid situation evaluation.
Chapter 10: Working with radar (Non-HD Digital)
MARPA automatically tracks acquired targets, calculates target bearing
and range, true speed and course, Closest Point of Approach (CPA) and
Time to Closest Point of Approach (TCPA).
Each tracked target can be displayed with a vector depicting approximate
target speed (vector length) and course (vector direction). The target data
can be displayed on-screen in the MARPA Target databox, each target is
continually assessed, and you are warned if one becomes dangerous or is
lost.
Effective MARPA operation is dependent on the accuracy of your own ships
heading data, plus Speed over Ground (SOG) and Course Over Ground
(COG). The better the quality of the heading data, the better MARPA will
perform. MARPA will function without SOG and COG data, but only relative vector, CPA and TCPA are shown; target course and speed cannot be
calculated.
Risk assessment
Each target is displayed as a symbol to indicate its status:
Target is being acquired
Target is safe
Target is dangerous
Target is lost
79
Each target is monitored to determine if it will be within a certain distance
from your own boat within a certain time. If so, the target is designated as
dangerous, and you are notified with an audible alarm and a flashing onscreen ‘MARPA target (ID No.) Dangerous’ warning. Press any key to
cancel the alarm and remove the warning; however, the target is
dangerous symbol remains displayed. Both the distance (Own Vessel Safe
Zone) and the time (Time to Safe Zone) are selectable.
If a target is lost, it is either because the MARPA software has lost contact
with it, or it has moved out of range. If this occurs, you are notified with an
audible alarm and an on-screen ‘MARPA target (ID No.) lost’ warning.
Press any key to silence the alarm and remove the message and lost target
symbol from the screen.
MARPA range
MARPA target acquisition is only available at radar range scales of up to 12
nm, although tracking continues at all ranges.
If you change to a smaller range scale, targets may be beyond the range of
your scanner and will be lost. In such cases, an on-screen warning will indicate that the target is off-screen.
Target and vector history
You can display MARPA targets with a vector line showing where they will
be at a certain time in the future (assuming their present course and speed
remains unchanged). You can select a relative or true vector, and the
vector length.
Relative vector
A relative vector indicates the target’s motion relative to your own boat’s
motion. The target’s relative course and sped are calculated to produce a
80
vector that is displayed on the target only. Relative vector mode is used for
collision avoidance and threat assessment.
True vector
A true vector indicates the targets motion over ground. In this mode, true
vectors for the target and your own boat are displayed. MARPA measures
the direction in which the target and your own boat are moving over the
ground. The result is the boat’s true course and speed. Consider this
motion as if you were in a helicopter looking down watching the targets
move across the water. This mode is used as an aid to navigation.
Target history
You can also view a target’s history, which appears as a trail of dots left by
the target as it travels. You can change the display interval of these dots.

Image quality
Side lobes
Not all radar echoes are produced by valid targets. Spurious echoes may be
caused by:
Side lobe patterns are produced by small amounts of energy from the transmitted pulses that are radiated outside the narrow main beam.
• Side lobes
• Indirect echoes
• Multiple echoes
• Blind sectors
• Sea, rain or snow clutter
• Interference
Through observation, practice, and experience, you can generally detect
these conditions very quickly and use the radar controls to minimize them.
The effects of side lobes are most noticeable with targets at short range
(normally below 3 nm) and with large objects. Side lobe echoes form either
arcs on the radar screen similar to range rings, or a series of echoes
forming a broken arc (see over)...

Indirect echoes
Blind sectors
There are several types of indirect echoes, or ‘ghost’ images. These sometimes have the appearance of true echoes, but in general they are
intermittent and poorly defined.
Obstructions such as funnels and masts near the radar antenna can
obstruct the radar beam and cause radar shadows or ‘blind sectors’.
False echo
True echo
True echo
If the obstruction is relatively narrow, there will be a reduction of the beam
intensity, though not necessarily a complete cut-off. However, with wider
obstructions there can be a total loss of signal in the shadow area. There
might also be multiple echoes which extend behind the obstruction.
Blind sector effects can normally be minimized by careful selection of the
scanner site prior to installation.
Mast
or funnel
False echo
Multiple echoes
Multiple echoes are uncommon but can occur if there is a large object with
a wide vertical surface at a comparatively short range. The transmitted
signal bounces between the object and your own vessel, producing
multiple echoes. The false echoes are displayed beyond the range of the
true target echo, but on the same bearing.
Radar returns from waves around the vessel can clutter the center of the
radar picture, making it difficult to detect real targets. Such ‘sea clutter’
usually appears as multiple echoes on the display at short range, and the
echoes are not repetitive or consistent in position.
In high winds or extreme conditions, sea clutter can produce an almost
solid disc on a radar display.

Radar detects rain and snow. Returns from storm areas and rain squalls
consist of countless small echoes which continually change in size, intensity and position. These returns sometimes appear as large hazy areas,
depending on the intensity of the rainfall or snow in the storm cell.
This can occur when two or more radar-equipped vessels are operating
within range of each other. The interference usually appears as a spiral of
small dots from the display center, and is most marked at long ranges

On-screen targets may be large, small, bright or faint, depending on the
size of the object, its orientation and surface type.
Remember that the strength of an object’s echo may not be proportional to
the physical size of the object. For example, a nearby object might produce
an echo of the same strength as a more distant, but larger object.

With experience, the approximate size of different objects can be determined by the relative size and brightness of the echoes.

Factors affecting echo strength
•
•
•
•
Your position
By default your boat is shown at the center of the radar display and your
dead-ahead bearing is indicated by a vertical line known as the Ship’s
Heading Marker (SHM).
•
Operation modes
The radar gives excellent results in one of the four pre configured operation
modes under the Gain softkey. Select the mode that best suits your
circumstances attempting to make manual adjustments to the settings
could degrade your image. (However, this facility is available.) See page 93
for more information.
•
•
The physical size of the reflecting object.
The material from which the object is made. Metallic surfaces
reflect signals better than non-metallic.
Vertical surfaces, like cliffs, reflect the radar signal better than
sloping surfaces, like sandbanks.
High coastlines and mountainous coastal regions can be observed
at longer radar ranges. Therefore, the first sight of land may be a
mountain several miles inland from the coastline. Although the
coastline may be much nearer, it may not appear on the radar until
the vessel is closer to shore.
Some targets, such as buoys and small boats, can be difficult to
discern, because they do not present a consistent reflecting surface
as they bob about in the waves. Consequently, these echoes tend
to behave erratically on the radar screen.
Buoys and small boats often resemble each other, but boats can
often be distinguished by their motion.
Trees and shrubbery’s do not reflect radar. Thus, they can disguise
the shape of nearby land.

11.5 Using waypoints with the radar
You can use waypoints in the radar application for navigation (just like in
the chart application), using the WPTS/MOB button.
You can also edit waypoints from within the radar application.
Heading-Up (H-UP)
This is the default mode for the radar application.
e.g:

The Presentation softkey on the radar toolbar gives you control over:
Waypoint behavior
Radar mode and orientation
Range rings
VRM/EBL behavior
Orientation
Radar orientation refers to the relationship between the radar display and
your direction of travel. There are three orientation modes:
• Head up
• North up
• Course up
These orientation modes are used in conjunction with motion modes (see
page 92) to control how your vessel’s progress is shown on screen.

If heading data becomes unavailable while in this mode, a warning
message will be shown, the status bar shows North-Up in brackets and the
radar uses 0° heading in relative motion. When heading data becomes
available once more, North-Up mode is reinstated.
It is not possible to select Head Up mode when the motion mode is set to
True.

The reference used for Course-Up depends upon the information available
at a given time. The system prioritizes this information in the following
order:
1. Bearing from origin to destination (your intended course).
2. Locked heading from an Autopilot.
3. Bearing to waypoint.
4. Instantaneous heading.
If heading data becomes unavailable while in this mode a warning
message is displayed; the status bar puts Course-Up in brackets to show it
is suspended; and the radar uses 0° heading in relative motion mode.
When heading data becomes available again, Course-Up mode is
reinstated.

Relative motion (RM) with optional vessel offset
When the motion mode is set to Relative, the position of your boat is fixed
on the screen and all the targets move relative to the boat.
You can specify whether the boat is fixed in the center of the window (0
offset) or offset by 1/3 or 2/3:
Setting the motion mode
Motion modes control how your progress is represented on the display. The

D6842-2
There are two motion modes:
The default vessel-offset value is zero.
True Motion (TM)
When the motion mode is set to True, fixed radar targets maintain a
constant position and moving vessels (including your boat) travel in true
perspective to each other and to fixed landmasses on the screen. As the
boat’s position approaches the edge of the screen, the radar picture is
automatically reset to reveal the area ahead of the boat.
If heading and position data become unavailable when true motion is
selected: a warning message is shown; the display reverts to relative
motion; the status bar indicates that True Motion is selected but suspended
by showing it in parentheses (TM).

4. Click Reset Vessel Offset softkey to restore default position.
11.7 Tuning the radar display:
Gain
Gain reduces the effect of false echoes and clutter. For best results, it is
recommended you retain the default AUTO setting. You can, however,
adjust gain settings manually if required.
Gain presets
There are four preset gain modes to give you the best picture in different
circumstances.
Harbor is the default mode. This setting takes account of land clutter so
that smaller targets, like navigation buoys, are not lost.
Coastal accounts for the slightly higher levels of sea clutter you might
encounter out of harbor and adjusts the radar display accordingly.
Offshore automatically adjusts for high levels of sea clutter.
The gain settings function makes the radar picture clearer by changing the
sensitivity of radar reception.
•
•
For long ranges select a sensitivity level that gives a slight
speckle in the background. Setting the gain too low can cause
weak or small targets to disappear, however.
For shorter ranges reduce the gain slightly to reduce speckle
and improve target definition.
Note: If you control gain manually, check it each time you change the
range scale.
To manually adjust gain settings
1. Click the Gain softkey.
2. Select a pre-set you want to adjust i.e. ‘Coastal Mode’.
3. Click the softkey you want to change the value for.
4. Once Man is shown, and the value percentage slider is displayed
above the softkey, use either a left mouse click for small changes (+/-1)
or a right mouse click for larger changes (+/-10).
5. Click Back to return to the top level.
The changes you make are applied to both the active window and any
other radar windows displaying this preset. Gain setting changes are kept
at system power-off.
Gain
The gain control makes the radar picture clearer by changing the sensitivity
of radar reception.
94
RayTech RNS V6.2 - User’s Guide
•
•
For long ranges - select a sensitivity level that gives a slight
speckle in the background. Be careful not to set the gain too low,
or you may miss weak or small targets.
For shorter ranges - reduce the gain slightly to reduce the
speckle and therefore improve target definition.
Note: If the gain settings are manually changed you should re-check it
every time you change the range scale.
Color Gain
The Color Gain control adjusts the intensity (color) of displayed targets, but
does not significantly adjust the number of targets displayed.
Increasing the color Gain will cause more targets to be displayed in the
same color. This may avoid some confusion as to whether a return on the
screen is a target or background noise.
Reducing the color gain may give better target detail, target discrimination
and target detection within clutter.
Radar colors
Radar returns/targets are represented as colors, in the default palette the
strongest returns are red with weaker returns being yellow, noise or clutter
is shown as aqua or blue.
Rain clutter
Radar detects echoes from rain or snow. The strength of these echoes
depends upon the altitude, range, density and size of the snow flakes or
rain droplets and appear on screen as countless small echoes continuously
changing size, intensity and position.
Turning the RAIN clutter function on suppresses the bulk effect of rain
returns from around your boat, so that recognizing other objects is easier.
Once Rain clutter is set to ON, use either a left mouse click for small
changes (+/-1) or a right mouse click for larger changes (+/-10).
Sea clutter
Radar echoes from waves around your boat can clutter the center of the
radar picture, making it difficult to detect real targets (see page 85).
Adjusting the sea mode will reduce this clutter for up to 5 nautical miles
(depending on wave and sea conditions) from your boat. This reduces sea
echoes to intermittent small dots, while small targets remain visible and
persistent. Gain levels further from your boat remain unchanged. The sea
clutter curve under Scanner Set up will effect the effectiveness of
this control (see Sea clutter curve on page 84).
11.8 Super HD adjustments

Noise or clutter
This scales the effective antenna size. At zero, the effective antenna size
matches its actual size. At 95, the effective antenna size is doubled.
Chapter 11: Using the Radar (HD and SuperHD Digital)
95
Increasing effective antenna size has the effect of separating targets that
appear merged at lower settings.
Turning interference rejection off altogether allows you to detect the presence of other radars in the vicinity.
In some circumstances, a larger effective scanner can be a drawback. In
particular, if you are in a harbor or close to land, you may see more detail
than is useful. For that reason, the AUTO settings for Harbor and Coastal
modes provide lower scale factors of about 30% and 60%.
To turn interference rejection off
1. Click the Enhance Echoes softkey from an active radar window.
2. Toggle the setting to Off on the Int Reject softkey.
Power boost
This adjusts effective transmit power. At zero, the radar operates at its
standard power (4kW or 12kW). At 90, the effective power is increased by
a factor of at least two.
Increasing power has the effect of making targets more distinct from noise.
For maximum benefit, reduce power boost to prevent saturation of strong
targets.
The default power boost setting for all AUTO modes is 90.
11.9 Tuning the radar display: ENHANCE
ECHOES
The ENHANCE ECHOES softkey gives you access to further features for
tuning the radar display.
Interference rejection
Interference rejection automatically reduces mutual radar interference
when two radar-equipped vessels are operating within range of each other.
It is switched on by default.
The strength (Normal or High) is accessed by pressing and holding the Int
Reject button when On is highlighted.
Expansion
The expansion function allows you to either override the pulse length or to
give larger returns so targets are easier to see.
To override the pulse length
1. Click the Enhance Echoes softkey from an active radar window.
2. Select Expansion softkey to turn expansion function On or Off.
Wakes
When the wakes function is switched on, you can see the direction and
speed of moving targets relative to your boat. Targets are displayed in
blue, turning to paler shades of blue as the signal diminishes.
The wakes option is a local setting which applies only to the display on
which you are working. You can choose to display wakes for a period of 10
seconds, 30 seconds, 1 minute, 5 minutes or 10 minutes.
To switch wakes display on
1. Click the Enhance Echoes softkey.
2. Toggle wakes to On using the Wakes softkey.
3. Select your preferred wakes setting with the trackpad.

Safety notices
MARPA can improve collision avoidance when used wisely. It is the User’s
responsibility to exercise common prudence and navigational judgements.
There are certain conditions under which acquiring a target may become
difficult. Some of those conditions are:
•
•
•
•
The target echo is weak.
The target is very close to land, buoys or other large targets.
The target or your own ship is making rapid manoeuvres.
Choppy sea state conditions exist and the target is buried in excessive sea clutter or in deep swells.
• Choppy sea state conditions exist yielding poor stability.
• Inadequate heading data exists.
Symptoms of such conditions are that acquisition is difficult and the
MARPA vectors are unstable; the symbol wanders away from the target,
locks on to the wrong target or changes to a lost symbol target.
If any of these conditions are present, acquisition and tracking may need to
be re-initiated or, in some cases be impossible to maintain. Improving the
quality of the heading data will reduce the effect of the other conditions.
To acquire a target
MARPA automatically tracks acquired targets, calculates target bearing
and range, speed and course, Closest Point of Approach (CPA), and Time to
Closest Point of Approach (TCPA).
Each target tracked can be displayed with a CPA graphic which shows the
target vessel, course and speed (as a vector) and indicates the CPA. The
calculated target data can also be shown on your screen. Each target is
continually assessed and an audible alarm is sounded if a target becomes
dangerous, or is lost.
Effective MARPA operation is dependant on accurate own-ship’s heading
and speed. Speed Over Ground (SOG) and Course Over Ground (COG)
information are required to show true target course and speed. The better
the quality of the heading and speed data, the better MARPA will perform.
MARPA will function without SOG and COG in relative mode. For the best
heading data a Raymarine SMART Heading Sensor or a gyro-stabilized
autopilot is required.
Risk assessment
Each target is monitored to see if it will be within a certain distance from
your boat within a certain time. If so, the target is designated as dangerous
and an audible warning is sounded along with an on-screen warning being
shown. The target symbol changes to the dangerous target symbol and
flashes to indicate that it is a dangerous target. Pressing the appropriate
soft key will silence the alarm and remove the warning.
If a target is lost, either because the MARPA software has lost contact with
it, or because it has moved out of range, an audible alarm is sounded and
an on-screen warning appears. The on-screen symbol will change to the
target lost symbol. Pressing the appropriate soft key will silence the alarm
and remove the on-screen warning and the target lost symbol.
MARPA range
MARPA target acquisition is only available at radar range scales of up to
12nm, although tracking continues at all ranges. If you change to a smaller
range scale, targets may be beyond the range of your scanner and will be
lost. In such cases, an on-screen warning will indicate that the target is offscreen, (See over page).

How motion modes affect CPA
In true motion mode, the vectors of your vessel and the target are shown
extended to their intersection point. The CPA is shown as a line that is
placed on your boat’s vector at the point of the CPA. The length and direction of the line indicates the distance and bearing of the target at CPA. The
text indicates CPA and TCPA. The text next to the target symbol indicates
its true course and speed.
In relative motion mode, no vector extension of your boat is shown.
The CPA line emerges from your own boat, with the target vector extension
being shown as relative, not true. The text next to the target indicates its
course and speed.

12.2 What is AIS?
AIS uses digital radio signals to broadcast ‘real-time’ information between
vessels and shore based stations via dedicated VHF frequencies. This information is used to identify and track vessels in the surrounding area and to
provide fast, automatic and accurate collision avoidance data. AIS will
augment your radar application, as it can operate in radar blind spots and
can detect smaller AIS fitted vessels.
WARNING: Smaller vessels do not have to be fitted with AIS
and whilst it is mandatory for larger commercial vessels to
carry AIS, its use is not. You should not therefore assume that
your AIS will display ALL vessels in your area. Due prudence
and judgement should be exercised.
WARNING: AIS should be used to complement not substitute
radar.
Note: Not all AIS receivers will decode all information and not all of the
Class A vessels input all of the required AIS data. For example,
some inexpensive AIS Class B receivers do not decode and output
the ship’s name, IMO number and vessel draft/beam/length, destination etc.

are displayed. As the vessel’s status changes, the symbol for the target will
change accordingly.
Vectors can be displayed for each target. These vectors indicate the direction of travel and rate of turn of the vessel and the distance it will travel
over a specified period of time (COG/SOG vector). Targets displayed with
their vectors are referred to as ‘active targets’ and are scaled according to
the size of the vessel. The larger the vessel the larger the target. You can

Chapter 13: Working with sonar
13.1 Introduction
Note: The RayTech sonar functions require a connection to a SeaTalkhs
network that includes a compatible Raymarine DSM sonar unit AND
a compatible Raymarine multifunctional display. The multifunction
display must be designated as the data master.
Raymarine Fishfinders use sound waves (sonar) to show you what is under
your boat, find fish and show the bottom of a lake or sea. The transducer
sends high-frequency sound waves down into the water; these sound
waves strike fish, the bottom or other objects in the water and are returned
as echoes. The fishfinder interprets these echoes to produce a visual representation of what is under your boat.
When connected to a DSM30, DSM 300, or DSM400 sonar RayTech can be
used as a fishfinder repeater.
For technical information on Sonar refer to: Appendix C - Sonar.
13.2 The sonar screen
When you first view the sonar screen, a scrolling bottom graph is displayed.
This is a graphical representation of the echoes seen by the sounder
module. As time passes this image scrolls from right to left and becomes a
record of the echoes seen. Default Sonar Screen - page 131 shows a typical
sonar picture.
The images at the right of the screen are the most recent echoes. Some
echoes indicate fish and others show the bottom. Bottom structure structures, such as a reef or shipwreck will also be indicated.
The sonar screen includes a status bar displaying transducer frequency and
gain settings. The display can also show upper and lower depth limits, and
depth lines if required.
As with all of RayTech’s applications, the sonar can be customized to let
you choose how the image is displayed and what information is displayed.
For example, you can set the scroll speed of the bottom graph and the
range can be changed to adjust the depth of water displayed.
Displaying sonar in a new page
To display sonar in a separate page:
1. Select FILE/Open New Page. The Open New Page dialog box will
appear.
2. Double- click the SONAR icon. The sonar display and associated softkeys will open in a new page.

Background color
The background color you select for the primary sonar page will be used on
all other sonar pages (zoom, bottom-lock and A-scope). You will probably
find that you need to change the background color in different light conditions. For example, a white background is probably easier to see in bright
sunlight, but a black background may be preferable at night.

Scrolling speed
The standard sonar display is a scrolling bottom image, which shows a
graphical representation of the echoes seen by the sonar. New information
appears at the right hand side of the screen and scrolls to the left. The
speed at which the display scrolls is adjustable, but the same section of the
bottom is displayed regardless of the scrolling speed.

D6998_1
Display shows
longer history
If you select a faster scroll speed, more detail is displayed, useful if you are
looking for fish, a slower scroll speed moves the information more slowly.
The sonar automatically adjusts the scroll speed, based on depth, but you
can also manually adjust the speed. If you select automatic adjustment, the
scroll speed is related to boat speed as follows:
• Less than, or equal to 0.5 kts, scroll speed is constant at 10%.
• Between 0.5 and 15 kts, scroll speed varies linearly with boat speed.
• Greater than 15 knts, the scroll speed is constant at 100%.
If you choose manual adjustment, the scroll speed is not related to the
speed of the boat over the bottom. You can also pause the display, but the
depth indication will continue to update.
You can select whether the depth is displayed for fish echoes. With the
target depth id set to On, the target depth is displayed just above each
target echo.
To turn on Target Depth ID:
1. Right mouse click on the sonar screen. The right-mouse menu is
displayed.
2. Scroll and check Fish ID. The target depths are displayed on the sonar
screen.
13.5 Improving the underwater view
The sonar automatically locates the bottom and displays the information as
a scrolling image using an appropriate scroll speed and range. To change
the view to suit your current activities and operating conditions, you can
control how the fishfinder image and depth information is displayed as
follows:
•
•
Change the displayed range; this affects all sonar pages.
View single and dual frequency sonar; this affects all sonar pages. The
sonar, by default, automatically determines the optimum frequency of
operation according to depth. You can manually select the transducer
116
•
•
frequency (50 kHz for wide coverage or 200 kHz for a narrow, detailed
view), or you can set split frequency mode to display both frequencies
in different pages.
Change the sonar display mode, for the active page, to view bottom
lock, A-scope or zoom images.
• Bottom lock provides a bottom up view. This mode is used primarily to filter out the bottom structure and thus show fish more
clearly. Bottom lock can be displayed full page, or split with the
scrolling bottom image.
• A-Scope displays a real-time image of the bottom structure and
fish directly below the transducer. The A-scope is displayed alongside the regular scrolling bottom graph.
• Zoom enlarges all or part of the bottom graph display so that you
can see more detail of the bottom structure, weeds etc. You can
select the magnification level and the zoom area. Zoom can be
displayed full page, or split with the scrolling bottom image.
Isolate fish close to the bottom using White Line and Bottom Fill in the
active pane.
Hide the depth digit in the current page.
Changing the range
The sonar automatically adjusts the display depth range, selecting the shallowest range that keeps the bottom image in the lower half of the display
page. Alternatively the RANGE button on the Pathfinder panel lets you
select the maximum depth displayed on the scrolling bottom and A-scope
images. You can also set the shift value to move the image up or down
within the current range. When auto-range is selected, the shift adjustment
is disabled and the value is ignored.
For full details of range and shift values refer to Range and shift values page 188.
To adjust the range:
D8775_1
•
RayTech RNS V6.2 - User’s Guide
1.Click RANGE on the Pathfinder panel. This sets the
adjustment to manual and the range softkeys are displayed.
2.Click RANGE to adjust the range as follows:
i.Click OUT to select a shallower range.
ii.Click IN to select a deeper range.
Selecting the operating frequency
The sonar uses dual frequency - 50 kHz and 200 kHz - to provide the
optimum image at different depths and can be used in either auto or
manual modes. The frequency setting is indicated in the status bar.
In Auto frequency the sonar automatically selects the appropriate
frequency, based on the current display range. As the depth increases, the
sonar switches from 200 kHz to 50 kHz at 250 ft. (80m). As the depth
decreases, the sonar switches from 50 kHz to 200 kHz at 150 ft(50m). This
affects all sonar widows. The Auto frequency setting is useful for automatically searching for the bottom.
In Manual frequency the following options are available:
•
•
Single frequency mode.
- In which you select the sonar frequency that is displayed in all sonar
pages.
Dual frequency mode.
- In which the transducer operates in both 50 kHz and 200 kHz
frequencies at the same time and you select the frequency that is
Chapter 13: Working with sonar
displayed in each page. This mode allows you to view both
frequencies simultaneously using multiple sonar pages.
50 kHz frequency
When using this frequency, the transducer scans a wide area. The signal
penetrates water well, so is good for use in deep water.
200 kHz frequency
When using this frequency, the transducer scans a narrower area, but
produces a more detailed view. The signal is good for finding fish that are
near the bottom or close together and is better for use in shallow water.
To change the frequency in a preset mode:
1. Click the preset to adjust (ADJUST P1).
2. Click the ‘Select Frequency’ to toggle between allowed frequencies.
Note: If you select Split Frequency, the screen is split horizontally, with the
200 kHz image in the upper pane and the 50 kHz image in the
lower pane.
13.6 Making the picture clearer
Various factors can affect the displayed image, in particular, debris and air
bubbles can cause background noise. You can minimize these effects using
the gain controls.
117
Gain mode
The gain of the display adjusts background noise by varying the echo
strength for display of the echoes. The value of the gain controls determine
the strength at which the echoes are displayed. If the gain is low only the
strongest echoes are displayed; as the gain increases, more, but weaker
echoes are displayed, such as those from air bubbles.
The gain controls should be set high enough to see fish and bottom detail,
but without too much background noise. Generally, a high gain is used in
deep/clear water; a low gain in shallow/murky water.
RayTech provides automatic or manual gain control adjustment. Automatic
adjustment is based on depth and water conditions. As conditions change
the auto-gain adjusts to display echoes with a minimum of background
noise. You can manually adjust the gain, but will need to re-adjust it as
conditions change.
Color gain mode
The color gain mode determines how echoes of different strengths are
displayed. The color gain sets the lower limit for the top color band. All
echoes with a signal strength above this value are displayed in the strongest color or shade.
These controls are:
Setting a low value produces a small band for the strongest color, but a
wide signal band for the other colors. Setting a high value gives a wide
band for the strongest color, but a small signal band for the other colors.
•
•
•
•
RayTech provides automatic or manual color gain adjustment. Automatic
adjustment displays colors based on current conditions, using as many
colors as possible, whilst minimizing noise and clutter. You can manually
adjust the color gain, but will need to re-adjust it as conditions change.
Gain mode.
Color gain mode.
TVG.
Color Threshold
118
TVG
Time Varied Gain (TVG) reduces surface clutter by reducing the gain in the
top 100 ft. of the display and is useful for reducing noise, such as that
generated by boat movement and floating debris that often appear in
shallow water. A low TVG value has little effect on gain in shallow water; a
high TVG value decreases the gain in shallow water so that only the strongest echoes are displayed. You can adjust TVG manually or automatically.
Color Threshold
Color threshold determines the amount of color you see displayed on
screen. Setting the threshold to 100% gives you the full range of colors
shown on-screen. The lower the setting the less colors are displayed.
To adjust the gain controls:
1. Click Presentation.
2. Click Gain. The gain control softkeys are displayed.
3. Click the appropriate softkey to adjust the gain control settings.

13.7 Getting a clear picture of the bottom
You can get a clearer picture of the bottom using the Bottom Lock function.
The normal scrolling bottom display provides a top-down view, referenced
from the surface of the water. Bottom lock shows a water column of fixed
height, referenced from the bottom that appears flat. It removes bottom
detail to provide an image of objects directly above the bottom and is
useful when you are looking for objects or fish that are feeding close to the
bottom.
You can select the bottom lock image to be vertically split with the
scrolling bottom image, or to replace the scrolling bottom image.
The bottom lock image - see Bottom lock - page 119 - appears at the left
hand side of the screen. The bottom appears as a straight line, but some
features may extend above this line. Depth from the bottom is referenced
at the right of the split screen, with the bottom shown as zero. Actual
depth is shown in the bottom left of the screen. Bottom lock range is
adjusted using the RANGE button.

The normal scrolling bottom display shows a historical record of sonar
echoes. The A-Scope screen - see A- Scope - page 121 displays raw sonar
data direct from the transducer beam.
This gives you a real-time image of bottom structure and any fish directly
below the transducer. This function is useful in showing the strength of
echo returned from an object. A-Scope also displays the patented Bottom
Coverage width indication.
A-Scope can be displayed in three modes:
•
Mode 1 -the image is angled outward as the signal width, indicated
with dotted lines, increases with depth.
• Mode 2 - the image expands to take up the entire A-Scope pane, giving
greater detail.
• Mode 3 - the left hand side of the Mode 2 image is expanded to the
entire pane. This mode gives the greatest resolution.
If a bottom lock or zoom image is displayed, selecting A-Scope automatically switches them off. If you have split frequency images displayed, AScope is automatically displayed in both panes.

The distance-behind- boat continues to update as your boat moves.
However, the vertical line does not scroll with the scrolling bottom image.
If the display range changes, the VRM maintains the same position and
may, therefore, move out of the visible display area. When you switch on
the VRM, it is displayed at its last position, unless this is off-screen. If its
last used position is off-screen, it will be displayed in the default on-screen
position.
If you use the VRM with the sonar in split frequency or zoom modes, it will
appear in both panes.
To use the VRM:
1. Click Presentation.
2. Click VRM softkey.
3. Click VRM/EBL to ON. The crosshair will appear on screen as dashed lines.
4. Use the cursor and left mouse button to move the VRM/EBL to the required
position, the depth and distance will update as you move it.
5. When the VRM/EBL is in the required position, let go of the left mouse button. The crosshair will remain in the selected position and change to solid
lines. The depth will remain constant, but the distance-behind-boat will
continue to update as the image scrolls.

13.12 Sonar alarms
Note: If RayTech is integrated with a DSM250 or DSM300, sonar alarms
may only be utilized if the PC is connected to a Raymarine multifunction display.
You can set up alarms to warn you of:
• Shallow water.
• Deep water.
• Fish.
Each alarm can be turned on and off as required.
Shallow water alarm
The shallow water alarm can be set at any depth between 2ft (0.5 fathoms/
1 meter) and 3000ft (500 fathoms/1000 meters). You set the depth at
which the alarm triggers. When the depth is less than that set, an audible
alarm sounds and a pop-up message describing the alarm is displayed. You
cannot set the shallow alarm to a depth greater than the deep alarm. To
cancel the alarm, click any button.
Deep water alarm
The deep water alarm can be set at any depth between 2ft (0.5 fathoms/1
meter) and 3000ft (500 fathoms/1000 meters). You set the depth at which
the alarm triggers. When the depth is less than that set, an audible alarm
sounds and a pop-up message describing the alarm is displayed. You
cannot set the deep alarm to a depth shallower than the shallow alarm. To
cancel the alarm, click any button.

14.5 Polar plotting
Data collection
This section explains how to use RayTech’s Polars tool to analyze and finetune your boat’s performance. Intended primarily for the experienced
sailor, polar uses a group of variables (such as apparent/true/current
corrected wind angles, boat speed, heel and pitch, etc.) to determine what
heading you should set your boat on to achieve the best target boat speed
under varying wind conditions. Analysis results are displayed using several
graph plots and data matrices, which can be edited to suit your needs. A
typical polars plot screen is shown below.
The accuracy of any analysis presented by the polars tool is dependent on
the volume and accuracy of the data collected. There are two primary areas
within the polars application where you can enter and modify data:
The Polar tab - this displays the polar parameters screen, which
contains variables/ values used to plot the polar graph.
• The Data tab - this displays the data tests screen, which enables the
input of advanced, boat/weather performance-related information that
you can use to further fine-tune the analysis.
These screens come pre-loaded with default data, however, it is essential
to replace as much of this information as possible with real performance/
atmospheric -specific data. You can use RayTech’s Data Trak and Data
Logging functions to record a wide variety of performance-related data
that is ideal for use with these screens. Data from these screens can also
come from such sources as your boat’s manufacturer and local nautical
organizations.
•
Entering and editing data
Data is entered using the polar and data parameters tabs.

entered in the polar parameters screen. These lines are displayed in
blue.
The lines that diverge between 30o and 50o, and 130o and 160o, represent the Target Twa upwind (5) and downwind (6). These lines are
displayed in blue.
The line that scribes a semi-circle, plots the optimum heading (7) and
resultant speed relative to the Tws range you enter at the bottom of
the screen. As the Tws range is increased, additional lines are plotted
onto the graph, showing the heading you should take to make
optimum progress as wind speed increases. These lines are displayed
in black.
The co-ordinate pop-up (8) shows the current boat speed and heading,
as entered into the data test screen.
The bottom axis (1) shows boat speed range in knots. The maximum/
minimum speed and speed interval are determined on the scale
plotted.
The top axis (2) describes an arc of 180o representing the boat’s direction with respect to the wind. At 0o you are sailing directly into the
wind, at 180o you are sailing directly with the wind.
In this example the lines that lie precisely on the 70o and 110o axes
correspond to the settings of the Twa1 (3) and Twa2 (4) variables
The upwind, downwind and Velocity Made good on Course (Vmc) screens
enable you to directly analyze those aspects of the polar plot by reducing
the displayed information to only those elements.
Upwind plot
The upwind plot screen calculates the best angle and boat speed when
sailing upwind and displays:

Tws (kts) up/down arrows or by entering the numbers directly.
Boat speed relative to Tws.
Click Bsp to view.
Twa relative to Tws.
Click Twa to view.
Vmc plot
The Vmc plot screen displays the Velocity Made good on Course towards a
specific mark or target. Although similar in concept to VMG, Vmc is equal
to VMG only when the bearing to the mark and wind direction are identical. Vmc is used when you expect the wind to change between your
present position and the target (primarily in long course racing).
In such an instance, it may be a smarter tactical move to sail toward your
target at the fastest possible speed, even if that heading isn’t directly
toward the target.
To use the Vmc plot, select the Course and true wind direction to be plotted
by clicking on the Course, Twd and Tws (kts) up/down arrows or entering
the numbers directly.
By default, course and Twd are initially derived from instrument input, but
the screen allows you to change these figures to calculate what happens if
the wind or course changes.

Instrument calibration for accurate data
The accuracy of data generated by your instruments and performance evaluation depends on accurate calibration. This section gives an introductory
explanation of instrument calibration, you must refer to the Manufacturer’s
manuals that came with your instruments for specific calibration procedures. The following calibration principles are explained:
•
•
•
•
•
Boat speed.
Compass.
Apparent wind angle.
True wind angle.
True wind speed.
Boat speed
Boat speed calibrations are entered directly into your instrumentation
system. While it may not be practical to check boat speed calibration on a
daily basis, you are encouraged to check this variable on a measured mile
as often as possible, as the paddle wheel impellers used to generate boat
speed data can change their physical characteristics markedly over their life
span due to the environment in which they operate. When making a
measured mile calibration, perform three consecutive runs over the known
distance, to eliminate any tidal current effects.
Compass
Compass calibration involves two procedures: deviation and heading error
calibration.
Calibrating deviation corrects compass error around different points of the
compass. Keep in mind that some instrument systems have the ability to
calibrate the compass automatically.
150
RayTech RNS V6.2 - User’s Guide
Heading error calibration ensures that the heading the compass indicate
always reflects your true heading. Calibration of this kind is usually
achieved by piloting the boat along a known line of transit. For best results,
you should have your compass swung by a professional.
Apparent wind angle
Apparent wind angle (Awa) calibration should be carried out after the
masthead wand is initially installed on your boat. The wand may not lie
exactly on the fore and aft line of the boat. Awa calibration is necessary to
compensate for this. Awa should read zero when the vane is on the centerline of your boat. If you don’t get a zero reading, you must enter an offset
value into the instrumentation system.
The amount of Awa alignment error can be established in two ways:
•
•
Take the boat heading into wind and read the Awa angle.
If the Awa value is not zero, there is a calibration error. This method is
not as accurate as the next.
• Perform two or three tacks upwind in even wind strength, then
compare the average Awa tack-to-tack using RayTech’s DataTrak
function.
Any calibration must be performed under even wind strength, as variances
will result in different Awa readings tack-to-tack. It is also important to
calibrate Awa offset in the absence of wind shear and wind gradient;
however, calibration in light air (such as a sea breeze filling in) is not
recommended.
•
•
Complete four to six tacks in steady wind conditions.
Use the ‘wand method’ of averaging the charts to ascertain the difference in Awa on each tack.
Once you have determined the Awa offset, enter it into the Masthead unit
offset parameter within your instrument system. Use half the difference
between the wind angle on each tack. This keeps the Awa symmetrical
tack-to -tack, because laylines are predicted based on the Awa.
14.6 DataTrak
With RayTech connected to your boat’s instruments you can use DataTrak
to record any of your instrument channels and display the collected data as
a time-based graph. This is useful for looking at trends, averages, real time
data and comparing instrument data. Information can be displayed in
default or customized pages.
DataTrak graphs can be resized to fixed time intervals for quick data
capture. This is invaluable to you in capturing data for target and polar
calculations or in trying to ascertain minute changes in any recorded variable over time. RayTech allows for the display of DataTrak wand times.
When capturing data from DataTrak, vertical frames can be inserted in the
chart to delineate start and end points for the data capture. These lines,
called wands, represent a particular segment of time on the graph. The
time interval is reported at the top of the graph, in the blue status bar.
You can create graphs to display the following information:
To achieve successful Awa offset calibration:
Air Temp
Used to identify air temperature.
•
Awa calibration
Used to set the alignment of the masthead wand.
BoatSpgSOG
Displays boat speed and Speed over Ground.

Chapter 16: Troubleshooting RayTech
169
Problem: RayTech is not connecting to any external SeaTalkhs devices
Possible cause
Solution
PC or laptop Network Interface Card (NIC) is not correctly connected or
configured.
•
•
•
•
•
•
If the PC requires a Local Area Connection to a non-Raymarine network
in addition to the SeaTalkhs network, an extra Network Interface Card
(NIC) should be installed to facilitate the non-Raymarine network.
Wireless Local Area Network (WLAN) network connections should be
disabled prior to starting the RayTech RNS 6.x software to prevent
possible detection of 10.x.x.x IP addresses over the WLAN. Raymarine’s
SeaTalkhs devices utilize static 10.x.x.x IP addresses. RayTech RNS 6.x
will prioritize 10.x.x.x IP address detected over the WLAN over nonwireless networks.
After RayTech RNS 6.x has established communications with the
SeaTalkhs network, then the wireless network connections can be
enabled.
Software firewalls should be disabled prior to running RayTech RNS 6.x.
RayTech RNS 6.x will attempt to disable the Windows Firewall.
However it is your responsibility to disable other third party software
firewalls (e.g. Norton, MacAfee, ZoneAlarm, Panda, etc.).
Before starting RayTech RNS 6.x, all SeaTalkhs devices and the
SeaTalkhs Network Switch (if so equipped) should be switched on.
Following boot-up of the PC, it is necessary to wait a few minutes to
permit the PC to complete the process of acquiring networks before
running RayTech RNS 6.x. The local area connection for the SeaTalkhs
network will typically report a status of “Limited or No Connectivity” or
“Connected”.
170
RayTech RNS V6.2- User’s Guide
Problem: RayTech is not connecting to any external SeaTalkhs devices
Possible cause
Solution
An incorrect Network Interface Card (NIC) is selected when running the
RayTech Network Connection wizard.
When running RayTech’s Network Connection Wizard, be certain to select
the SeaTalkhs Network Connection radio button and the proper Network
Interface Card (NIC) (that to which the SeaTalkhs cable is connected). Any
NIC with wireless in its title can typically be ruled out during this step.
After RayTech RNS 6.x has completed initializing, wait a minute or so for
RayTech to connect to the networked SeaTalkhs devices. If RayTech is
unable to connect, a static 10.x.x.x IP address should be configured:
•
•
•
•
•
•
•
•
•
•
To find out the IP address of your multifunction display, select MENU >
System Diagnostics > External Interfaces > SeaTalk HS on your multifunction display. To find out the IP addresses of your other networked
SeaTalkhs equipment, select MENU > System Diagnostics > External
Interfaces > SeaTalk HS on your multifunction display and select the
DEVICES softkey. Make a note of the IP addresses.
From the Windows Start Menu, select Start->Settings->Control Panel.
Double-click "Network Connections".
Right-click on the Local Area Connection icon to which the SeaTalkhs
network is physically connected and select Properties.
Click Internet Protocol (TCP/IP).
Click Properties.
Select the "Use the following IP address" radio button.
Enter an unused, valid 10.x.x.x IP address (e.g. 10.213.89.33).
Enter 255.0.0.0 as the Subnet mask, then click OK.
Use the Network Connections dialog to monitor the Status of the
connection. It will typically specify “Limited or No Connectivity” or
“Connected” once it has established a connection with the SeaTalkhs
network.
Chapter 16: Troubleshooting RayTech
171
Problem: RayTech is not connecting to any external SeaTalkhs devices
Possible cause
Solution
The SeaTalkhs equipment is correctly connected but not communicating.
To test the SeaTalkhs cabling, Network Switch, SeaTalkhs Crossover Coupler,

Problem: RayTech Planner
Possible cause
Solution
What is RayTech Planner?
RayTech Planner is essentially an unlicensed version of RayTech RNS software. RayTech Planner can be used to plan waypoints and/or routes at
home and export the waypoints and/or routes to a memory card (memory
card reader/writer and memory card supplied by the user) in a format that
can be used in conjunction with Raymarine Multifunctional display products. RayTech Planner permits the user to download free 3-Day Weather
Forecast GRIB files that can be animated to show storm tracks, wind, and
rain. RayTech Planner additionally permits users to access Tide and Current
data to aid in voyage planning. As RayTech Planner is an ‘at-home’ tool, it
can not be used to connect to live instruments or GPS. If you wish to
connect to live instruments and GPS, or share radar, chart and fishfinder
information from Raymarine multifunction displays or Pathfinder PLUS
displays you must upgrade to the full version of RayTech RNS.
RayTech Planner is asking me for a licence key.
When initially running RayTech Planner, the RNS Startup Wizard will prompt
you for a Full RayTech RNS license number, a RayTech RNS Upgrade license
number, or to select to use RayTech Planner only (no license required). If
you have downloaded RayTech Planner from Raymarine's website or have
received a RayTech Planner CD with a new multifunction display, or have
received a RayTech Planner CD with the Navionics Multicard Reader, you
should choose the RayTech Planner (No License) option.

A.2 Safety
CAUTION: The equipment should not be used as a substitute for
good navigational practice nor for official government paper
charts.
RayTech makes it very easy to place a waypoint and travel towards it.
However, you should always check first that the route is safe. If you are
using RayTech in combination with an autopilot, the autopilot will prompt
for confirmation before it steers the boat towards the waypoint.
If you have entered a route using a small scale chart, zoom in to a larger
scale to check for hazards, such as small shoals, that may not be shown on
the smaller scale charts.
Note: Until you are familiar with interpreting the chart display, you should
take every opportunity to compare the displayed objects with visual targets,
such as buoys and coastal structures. You should practise harbor and coastal
navigation during daylight and in clear weather conditions.

A.4 Chart types
Charts fall into three basic types:
Vector
A paper chart that has been digitized into a format consisting of line
segments. Vector charts can be easier to read than a rasterized chart, but
may not include the level of detail found in Raster charts. C-Map charts are
examples of a vector chart.
Raster
A paper chart that has been scanned into a high resolution image. A raster
chart has the advantage of being virtually identical to the original paper
chart from which it was scanned. Maptech NOAA/BSB and PCX charts are
examples of raster charts.

RayTech RNS V6.2 - User’s Guide
Aerial imagery
A high resolution, geo-referenced rasterized photograph taken from aerial
or satellite sources. You can overlay your boat’s position on such an image,
and get a visual estimation of your position with reference to actual,
photography based landmarks. Navionics aerial photographs and Maptech
Photo Region charts are examples of this type of chart.
A.5
Displaying chart object and source
information
Vector charts used with RayTech include a number of displayed objects for
which information is available, such as lights and buoys. They also contain
additional source data for structures, lines, open sea areas etc. You can use
the right mouse menu to identify an object or chart position and you can
obtain detailed information for the selected item.
Waypoints
A Waypoint is a position entered on a chart as a reference, or as a place to
go. All waypoints placed on the chart plotter are stored in a waypoint database list which includes additional information about each individual
waypoint.
Routes
A route is made up of a series of waypoints. To make a route a series of
waypoints is placed on the chart, or can be selected from the Waypoint
List.
When a route is created it becomes the current route and is displayed onscreen. The current route is maintained even when the system is poweredoff. Only one route can be current and is displayed (if it is in the field-of-
view) as solid lines connecting waypoints. If the route is being followed,
the current leg is shown as a dotted line and the previous legs are removed
from the screen (although the waypoints remain displayed).
Tracks
The track function is used to mark on-screen the trail that the vessel has
followed, as if it had left a visible wake.
While the track is switched on it is recorded in the system memory. The
interval at which track points are made and a line is drawn on-screen
between each point. The current track remains on screen, even following a
power off/on, until you clear the track.
Note: RayTech does NOT support the import or export of tracks to or from
external equipment, such as multifunction displays. RayTech
produces its own .log track files when connected to relevant
equipment (such as a device with GPS capabilities).

Appendix B: Radar
Introduction
Scanner
This appendix describes the basics of radar and things that can affect the
radar picture.
The radar scanner unit illuminates targets with microwave energy and then
collects the reTurns from those targets. The scanner includes a sensitive
low-noise front end receiver, and a variety of clutter attenuation controls to
maintain target resolution.
B. 1 What is radar?
Radio Detection And Ranging (RADAR) is something that is in use all
around us, although it is normally invisible. One of the most common uses
of radar at sea is to detect the presence of objects, known as ‘targets’ at a
distance, and if they are moving, detect their speed.
The scanner is adjusted and operated from the display screen. It can be
switched between transmit and stand-by modes. It also has a power-saving
timed transmit mode which pauses between bursts of transmissions.
Until you are familiar with interpreting the radar display, every opportunity
should be taken to compare the radar screen patterns with visual targets,
such as other boats, buoys and coastal structures. You should practice
harbor and coastal navigation during daylight hours and in clear weather
conditions
B. 2 Maximum radar range
Maximum radar range is essentially line of sight, so is limited by the height
of the scanner and the height of the target as illustrated below:

The following table shows typical maximum radar ranges for various radar
antenna and target heights. Remember that although the radar horizon is
greater than the optical horizon, the radar can only detect targets if a large
enough target is above the radar horizon.
Concentric range rings are included to help in the judging of distances
on the radar picture. Their number and spacing are adjusted automatically if the range scale is changed. Range rings can also be turned off.

The radar picture can be viewed at various scales. The shortest range scale
gives a maximum range of 1/8 nm, measured from the default center to the
top of the radar picture. The longest range scale gives a maximum range of
between 24 and 72 nm depending on the scanner.

Long range scales provide the best overview of the boats relationship
to land masses, weather fronts and large ship targets in or beyond
view.
Short range scales provide greater detail of the radar echoes close to
the boat, and should be used as the coastline, harbors or other boats in
the area are approached.
*The maximum range depends on scanner type.

picture, at the standard ring interval for the current range, and are visible

in the distance. In addition, some echoes may be indirect reTurns to the
radar scanner, providing false echoes or multiple echoes.
B. 4 Interpreting the radar picture
Identifying false echo returns
Navigational echoes may be large, small bright or faint, depending not only
on the size of the object but also on its orientation and surface. Different
objects reflect the radar signals in different ways. For example, vertical
objects such as cliffs reflect signals better than sloping ones such as
sandbanks.
Not all echoes are direct reTurns to the radar antenna. Occasionally signals
appear at positions where there is no actual target. These are called false
echoes, and may be caused by side lobes, ghost images, indirect echoes or
multiple echoes.
High coastlines and mountainous coastal regions can be observed at the
longest radar range. However, the first sight of land may be a mountain
several miles inland from the coastline. The actual coastline may not
appear on the radar until the boat is close to the line of sight distance.
The radar indication may not be similar to your visual observation; a nearby
small object may appear to be the same size as a distant large object on
the radar. However, with experience the approximate size of different
objects can be determined by the relative size and brightness of the echoes.
Some targets, such as buoys and small boats, can be difficult to differentiate, since they bob and toss about in the waves and do not represent a
consistent reflecting surface. Consequently, these echoes have a tendency
to fade and brighten, and at times, to disappear momentarily. Buoys and
small boats often resemble each other, but boats can usually be distinguished by their motion.
Not all radar echoes are produced by hard navigational items. Some echoes
may be received from irregularities on the surface of the water, particularly
at close range (sea clutter), or from rain or snow either around the boat or
The effects of many false echoes can be minimized, and the target presentation clarified.
This section briefly describes the echo patterns that can be produced by
false echoes and the likely cause. It should be noted that the radar operator, through observation, practice, and experience, can generally detect
these conditions very quickly. These effects can usually be minimized using
the radar controls.

False echo
Main lobe
Side lobe patterns are produced
by small amounts of energy from
the transmitted pulses that are
radiated outside the narrow main
beam.
Side lobe

Arc True echo
Side echoes
The effects of side lobes are most
noticeable with targets at short
ranges (normally below 3nm), and
in particular with larger objects.
Side lobe echoes form either arcs
on the radar screen similar to
range rings, or a series of echoes
forming a broken arc.
D7051_1
Indirect echoes
There are several types of indirect echoes or ghost images. These sometimes have the appearance of true echoes, but in general they are
intermittent and poorly defined.

Multiple echoes
Multiple echoes are not very common but can occur if there is a large
target with a wide vertical surface at a comparatively short range. The
transmitted signal will be reflected back and forth between the target and
your own boat, resulting in multiple echoes, displayed beyond the range of
the true target echo, but on the same bearing.
185

D1642-1
D7053_1
True echo
Multiple echoes
Blind sectors or shadow effect
Obstructions such as funnels and masts near the radar antenna may
obstruct the radar beam and cause radar shadows or ‘blind sectors’. If the
obstruction is relatively narrow, there will be a reduction of the beam
intensity, though not necessarily a complete cut-off. However, for wider
obstructions there may be a total loss of signal in the shadow area. There
may also be multiple echoes which extend beyond the obstruction. Blind
sector effects can normally be minimized by careful selection of the scanner
site prior to installation.
D7054_1
Radar returns from waves around the
boat can clutter the center of the radar
picture, making it difficult to detect real
targets. Such ‘sea clutter’ usually appears
as multiple echoes on the display at short
range scales., and the echoes are not
repetitive or consistent in position. With
high winds and extreme conditions,
echoes from sea clutter may cause dense
background clutter in the shape of an
almost solid disc.
Rain clutter
The radar can see echoes from rain or
snow. ReTurns from storm areas and rain
squalls consist of countless small echoes
that continuously change size, intensity
and position. These reTurns sometimes
appear as large hazy areas, depending on
the intensity of the rainfall or snow in the
storm area.
D7055_1

RayTech RNS V6.2 - User’s Guide
Interference
When two or more radar-equipped boats
are operating within range of each other,
mutual radar interference can occur. This
usually appears as a spiral of small dots
from the display center. This type of interference is most noticeable at long ranges.

Appendix C: Sonar
C.1 Introduction
C.3 Bottom indications
The sonar provides a detailed underwater view that helps you to see
bottom structure and texture, underwater obstructions such as wrecks and
fish. Depth data is also provided and depth and temperature alarms can be
set.
The bottom usually produces a strong echo, enabling the sonar to see great
detail.
C.2 How the sonar works
The sonar application uses a Digital Sounder Module (DSM) to process
sonar signals from a suitable transducer and provide a detailed underwater
view.
The transducer located on the bottom of the boat sends pulses of sound
waves into the water and measures the time it takes for the sound wave to
travel to the bottom and back. The returning sound echoes are affected by
bottom structure and any other objects in their path, e.g. wrecks, reefs and
fish.
The DSM processes these echoes and sends data to the sonar which
displays a visual interpretation of the underwater view. The strength of
echoes is indicated on the display by different colors. You can use this
information to determine the bottom structure, the size of fish and other
objects in the water, e.g. debris or air bubbles.
Notes:
1. The DSM will operate at a frequency of 50 kHz and/or 200 kHz.
2. Some transducers will enable the sonar to display water temperature and/or speed data.
D7057_1
A hard bottom, such as sand, produces a thin line.
D7058_1
A softer bottom covered with seaweed produces a wide line, as the sound
waves reflect from different layers of the bottom. In this image the sonar is
getting a good echo from the bottom, so the upper layer of the bottom is
shown as dark gray.
D7059_1
An uneven bottom which is covered with rocks or coral produces a complex
display; the bottom image is irregular, with long tails pointing upward. A
wreck produces a similar image.
188
RayTech RNS V6.2 - User’s Guide
Notice that the lower layer of the image is shown as a lighter gray, indicating a weaker echo. This could mean that the upper layer is soft; some
sound waves may get through this layer and be reflected by a more solid
layer below.
The same target will appear differently when the transducer frequency is
changed. The lower the frequency, the broader the mark.
It is also possible that the sound waves are making two complete trips hitting the bottom, bouncing off the boat, the reflecting off the bottom
again. This can happen if the water is shallow, the bottom is hard, or gain
is set high.
Although weaker than bottom or other echoes, your sonar picture may be
impaired by echoes received from floating or submerged debris, air bubbles
or even your boats movement. This is known as ‘background noise ‘or
‘clutter’ and is controlled by the gain modes (gain, color gain and TVG).
Raymarine recommends that you allow your system to automatically
control the ideal sensitivity level based on depth and water conditions. You
can however adjust these settings manually if you prefer.
C.4 Displaying targets
When a target is detected, it is displayed on the sonar screen as a mark.
The size and shape of this mark is influenced by a combination of factors:
Boat speed
The shape of a target changes along with the boat speed. Slower speeds
return flatter, more horizontal marks. As your boat’s speed increases, the
target will tend to thicken and arch slightly; until at fast speeds the mark
resembles a double vertical line.
Target depth
The closer the target to the surface, the larger the mark on the screen. Individual target depths can be displayed using the Target Depth ID function.
Target size
The larger the target, the larger the return on the sonar display. However,
the size of a fish target is dependent upon the size of the fish’s swim
bladder rather than it’s overall size. Swim bladder size varies from fish to
fish.
Transducer frequency
C.5 Factors that can impair an image
C.6 Range and shift values
By default, the sonar automatically adjusts the display depth range,
selecting the shallowest range that keeps the bottom in the lower half of
the display window.
Alternatively clicking the RANGE button lets you select the maximum
depth displayed on the scrolling bottom and A-Scope images. You can also
shift the image up or down within the current range. When you select Auto
Range, the shift adjustments is reset to zero. Range adjustments affect all
sonar windows.
The range setting is indicated in the sonar status bar. The following table
shows the range and shift values that are available.

Appendix D: Installation Guidelines
D.1 EMC installation guidelines
All Raymarine equipment and accessories are designed to best industry
standards for use in the recreational marine environment.
Their design and manufacture conforms to the appropriate Electromagnetic
Compatibility (EMC) standards, but correct installation is required to ensure
that performance is not compromised. Although every effort has been
made to ensure that they will perform under all conditions, it is important
to understand what factors could affect the operation of the product.
The guidelines given here describe the conditions for optimum EMC performance, but it is recognized that it may not be possible to meet all of these
conditions in all situations. To ensure the best possible conditions for EMC
performance within the constraints imposed by any location, always ensure
the maximum separation possible between different items of electrical
equipment.
•
•
equipment, but may cause the loss of some information and may
change the operating mode.
Raymarine specified cables are used. Cutting and rejoining these
cables can compromise EMC performance and must be avoided unless
doing so is detailed in the installation manual.
If a suppression ferrite is attached to a cable, this ferrite should not be
removed. If the ferrite needs to be removed during installation, it must
be reassembled in the same position.
Suppression Ferrites
For optimum EMC performance, it is recommended that wherever possible:
•
Raymarine equipment and cables connected to it are:
• At least 3 ft. (1m) from any equipment transmitting, or cables
carrying radio signals, e.g. VHF radios, cables and antennas. In the
case of Single Side Band (SSB) radios, the distance should be
increased to 7 ft. (2m).
• More than 7 ft. (2m) from the path of a radar beam. A radar beam
can normally be assumed to spread 20 degrees above and below
the radiating element.
• The equipment is supplied from a separate battery to that used for
engine start. Voltage drops below 10 V, and starter motor transients, can cause the equipment to reset. This will not damage the
D6626-1
The illustration shows typical
cable suppression ferrites used
with Raymarine equipment.
Always use the ferrites supplied
by Raymarine
Connections to other equipment
If your Raymarine equipment is to be connected to other equipment using a
cable not supplied by Raymarine, a suppression ferrite MUST always be
attached to the cable near to the Raymarine unit

D.2 System integration
This section provides an overview of system integration and the protocols
that interface with RayTech.
The following illustration shows an example of a fully-integrated SeaTalkhs
system featuring RayTech:
What is System Integration?
System integration enables various instruments and displays to communicate with each other and use the collected data to increase the
functionality of the system.
This data exchange is only possible if the data gathering is accurate, and
transfer between instruments is fast and accurate.
Fast and accurate data transfer is achieved by using a combination of the
following data protocols:
•
•
•
•
SeaTalk.
SeaTalk2.
SeaTalkhs.
National Marine Electronics Association (NMEA)0183.
SeaTalk
The SeaTalk protocol was originally developed by Autohelm (part of
Raymarine) and enables compatible instruments to be connected by a
single cable carrying power (12 volts, 150 mA) and data in/out, without a
central processor, creating a simple network.
Additional instruments and functions can be added to a SeaTalk system,
simply by plugging them into the network. Some SeaTalk equipment can
also communicate with other non-SeaTalk equipment via the NMEA 0183
standard.
SeaTalk2
SeaTalk2 protocol was developed as the Controller Area Network (CAN)
based version of SeaTalk.
SeaTalkhs
The SeaTalkhs protocol was developed by Raymarine to enable high speed
Ethernet data transfer between Raymarine multifunction displays, DSM
sonars and RayTech PCs. This Local Area Network (LAN) enables all of the
multi-function displays connected in a system to show data from any
display in the system on all the other linked Raymarine multifunction
displays. This data can be displayed in full, split and overlay screen modes.
NMEA 0183
The NMEA 0183 Data Interface Standard was developed by the National
Marine Electronics Association of America. It is an international standard
to enable equipment from many different manufacturers to be connected
together and share information.
The NMEA 0183 standard carries similar information to SeaTalk. However
it has the important difference in that one cable will only carry information
in one direction. For this reason NMEA 0183 is generally used to connect a
data receiver and a transmitter together, e.g. a compass sensor transmitting heading to a radar display.
This information is passed in ‘sentences’, each of which has a three-letter
sentence identifier. It is therefore important when checking compatibility
between items that the same sentence identifiers are supported, e.g. VTG
carries Course and Speed Over Ground data, GLL carries latitude and longitude, DBT carries water depth and MWV carries relative wind angle and
wind speed data.
Installation Guidelines
D.3 Basic NMEA and RS-232 cabling principles
This section explains some of the basic principles involved with NMEA and
RS-232 electrical connections.
Knowledge of this information is not required to connect RayTech to your
peripheral instrumentation: however, it is provided for the advanced user
as a pertinent technical background.
NMEA basics
Most marine electronic devices that output data do so over NMEA ports.
These ports are known as a ‘balanced pair’, which means that the data
signal is carried over two wires (via an RS-422 electrical layer, in computer/
datacom terminology). The signal level is determined by calculating the
voltage difference between the two wires, hence the NMEA output signal
is called a Differential Data Signal (DDS). This DDS should not be confused
with Differential Global Positioning System (DGPS), which is a GPS system
error correction method.
DDS are designed to be error-resistant by keeping the positive and negative
leads close together for the entire cable run. This means that they both pick
up the same levels of noise, which is ultimately subtracted from the signal,
preserving the signal’s data integrity.
NMEA ports typically have four connections (two for each lead); Transmit
(positive/negative) and Receive (positive/negative). Some devices may use
a single-direction port, meaning that they can transmit or receive only.
To connect one NMEA device to another:
1. Connect device A’s positive Transmit (Tx+) lead to device B’s positive
Receive (Rx+) lead.
2. Connect device A’s negative Transmit (Tx-) lead to device B’s negative
Receive (Rx-) lead.
193
IMPORTANT: When performing the above connection, make sure that you
connect the devices directly; DO NOT use the boat’s DC grounding circuit to
carry the Tx- or Rx- signal.
You may encounter a device that does not properly implement the NMEA
specification, and shares it’s Tx- lead with the device DC power ground
circuit. In this case, you must still run a cable directly between the Tx- and
Rx- leads as previously stated. DO NOT share the DC power ground circuit.
RS-232 basics
Most desktop and laptop computers have RS-232 ports. These ports use a 3
wire interface, in which the transmit and receive leads reference the same
signal ground. It is important not to confuse the RS-232 cable’s ground
with the boat’s power ground circuit. While the boat’s power ground may,
co-incidentally, be at the same level as the RS-232 signal ground, there is
no industry standard that requires this. Since the RS-232 transmit and
receive data signals reference a common signal ground to maintain their
integrity, you must connect the signal ground circuit directly between the
two RS-232 linked devices.
To wire one RS-232 device to another:
1. Connect device A’s Tx lead to device B’s Rx lead.
2. Connect device A’s Rx lead to device B’s Tx lead.
3. Connect device A’s signal ground (SGnd) lead to device B’s SGnd lead.
RS-232 uses a common ground, which differs in electrical specification
form NMEA’s transmit/receive- pair arrangement. Because of these signal
level differences, the way you interconnect an RS-232 device and an NMEA
device varies with the application.
Note: You may also encounter voltage differences when interconnecting
older RS-232/NMEA hardware. Take care to ensure the correct
connections.
194
RayTech RNS V6.2 - User’s Guide
To wire an RS-232 device to provide input to an NMEA device:
1. Connect the RS-232 device TX lead to the NMEA device RX+ lead.
2. Connect the RS-232 device SGnd lead to the NMEA device RX- lead.
•
To wire an RS-232 device to provide and receive input from
an NMEA device:
1. Connect the RS-232 device Tx lead to the NMEA device Rx+ lead.
2. Connect the RS-232 device Rx lead to the NMEA device Tx+ lead.
3. Connect the RS-232 device SGnd lead to the NMEA device Tx- and Rxleads.
There are some infrequent cases where binding the NMEA device Tx- and
Rx- leads together may cause difficulties. If you do encounter problems,
you will need to use an RS-232 to NMEA converter between the two
devices. A converter is required in rare cases, but is a good place to begin
troubleshooting if problems arise with the RS-232/NMEA connection. It
should be noted that the modern Furuno radar systems do require a
converter.
D.5 Cables and cable runs
D.4 Circuit grounding issues
D.6 Proper cable shielding
The most important issue in electrical connections is proper circuit
grounding. In addition to all of the other electrical gremlins that poor
grounding gives rise to, instrument signals are easily scrambled if they are
badly grounded. This results in erratic and unreliable displays. Installations
using both AC and DC current have a separate ground circuit for each. In
such cases, the checklist that follows will ensure that the ground circuits
are kept fully isolated:
For all but the shortest length cable runs, data cables must be shielded to
prevent them from picking up electrical noise from other devices, and to
keep them from radiating potential interference. If you encounter a data
corruption problem, a good place to begin troubleshooting is with the
cable shielding, especially on longer cable runs. Make sure the cable
shielding hasn’t been scraped off by being squeezed through a tight area.
•
•
Always use isolating transformers or a separate power-inverter to run
PC, monitors and other sensitive electronic instruments or devices.
Always use an isolating transformer with weather FAX audio cables.
•
Always use an RS-232/NMEA converter with optical isolation on the
signal lines.
Always use PC’s and other devices that are directly DC powered.
When installing system cables consider the following:
•
•
•
•
•
All cables should be adequately secured, protected from physical
damage and exposure to heat. Avoid running cables through bilges or
doorways, or close to moving or hot objects.
Acute bends must be avoided.
Where a cable passes through an exposed bulkhead or deckhead, a
watertight feed-through should be used.
Secure cables in place using tie-wraps or lacing twine. Coil any extra
cable and tie it out of the way.
Do not pull cables through a bulkhead or deckhead using a cord
attached to the connector. This could damage the connections.
D.7 Preventing interference and crosstalk
You should always run data cables:
•
as isolated as possible.
Installation Guidelines
•
as far away from high current carrying AC and DC power lines as
possible.
• as far away from antennas as possible.
While it may be convenient to bundle power and data cables together, this
causes crosstalk between them, which results in scrambled and unusable
data. If you must cross a power cable when running a data cable, try to
make the crossing as close to 90o as possible; never run power and data
cables parallel within the same bundle.
195
To connect RayTech directly to an NMEA GPS:
1. Verify that GPS NMEA output is turned ON.
2. Set the GPS datum to WGS84.
3. Using Raymarine cable, Part No.E86001, connect the leads as follows:
Cable color
GPS lead
Yellow (Rx)
If you have long cable runs planned for data cables, and are using NMEA
equipment, use a shielded twisted pair cable to eliminate the danger of
interference and crosstalk.
NMEA + output
may also be labelled Tx, Tx+, Data out +, or NMEA
OUT +.

Raymarine (SeaTalk and SeaTalkhs) devices.
Connecting RayTech to your instruments
The connection between the PC that is running RayTech and your instruments is achieved using a serial data cable, Raymarine Part No. E86001.
One end of the serial data cable connects directly to your PC’s Serial Port,
the other to the various devices.
If your PC does not have a serial port, you will require a USB/Serial adapter.
For full details of suitable adapters refer to www.raymarine.com
Connecting directly to an NMEA GPS
Connecting RayTech to a Global Positioning System (GPS) is the simplest
way to get position data.
Connecting

directly
to
NMEA
equipped
Many instrument systems are equipped to accept incoming NMEA data
from your GPS, and will output additional collected NMEA data, such as
position, heading, speed, water depth etc.

D.9 Connecting Raymarine equipment
The sections that follow detail how to connect RayTech to Raymarine
SeaTalk and SeaTalkhs equipment.
SeaTalkhs
The PC on which you are running RayTech can be connected to external
SeaTalkhs equipment as part of an integrated system or as a single
repeater.
Raymarine recommends the use of a SeaTalkhs patch cable to connect your
PC or laptop to a SeaTalkhs switch.
For connecting to a single Raymarine multifunction display you will need to
purchase a SeaTalkhs Crossover Coupler, Part No.E55060. Raymarine
recommends the use of SeaTalkhs network cables to connect the Crossover
Coupler to the PC or laptop and the SeaTalkhs device.
If you want to display custom channel data from ST290 graphic displays on
RayTech, e.g. polar targets, you will need to connect RayTech to SeaTalk
using a RayTech SeaTalk/PC/NMEA interface, Part No. E85001. For full
details of this connection refer to “RayTech SeaTalk/PC/NMEA Interface:”
on page 199.
To connect a PC to an integrated SeaTalkhs system:
1. Connect the ethernet port of the PC to the SeaTalkhs network switch
using a SeaTalkhs patch cable.
2. Power the PC.
3. Open RayTech on the PC.
RayTech will now run an internal program to automatically create an IP
address and connect to the SeaTalkhs network.
4. In RayTech open a new radar page.
5. With the radar scanner powered check that you can change range on
the Raymarine multifunction display using RayTech.
If the range changes the units are communicating using SeaTalkhs.
6. You can now set up RayTech for use as you require.
To connect a PC to a single Raymarine multifunction display:
1. Connect the ethernet port of the PC to the SeaTalkhs Crossover
Coupler, using a SeaTalkhs network cable.
2. Connect the SeaTalkhs Crossover Coupler to the display using a
SeaTalkhs network cable.
3. Power the PC.
4. Open RayTech on the PC.
