Overall operation related changes
Navigation sensors
• If position alignment is used then user is reminded of it every 30 minutes. Alarm "2011 ChartAlign: over 30
min".
• In multiple sensor case the Kalman filter indicates changes in its position sources with a new alarm "2010
Filter: Pos source change".
• Kalman filter uses always higher priority for known high precision position sensors than for normal position
sensors (i.e. A DGPS has always higher influence to estimate than a GPS or LORAN)
• Alarm "4027 DGPS pos source change" uses now always a continuous beep until acknowledged. Before the
beep style was dependent of the steering mode. Also the priority of this alarm is readjusted (before some less
important alarm could suppress it in the priority list).
• Alarm "2008 Filter. Speed below 4kt" is now based on ground speed (before water speed). The Kalman filter
indicates this situation also with an permanent indication of BAD FILTER.
• Reference target based gyro error correction has now an alarm for lost correction value. Alarm "2353 RefTgt:
Lost gyro corr.".
• Activation of Reference target requires that there is at least 8 free tracking channels available. If the connected
ARPA radar has less than 8 free tracking channels then there is an alarm "2353 RefTgt: Tracking full".
Route Monitoring
• Selection of "Center and border lines for ARPA radar display" .in route monitoring window is dependent of
used radar display type.
• Alarm "2457 Route: Outside channel limit" is activated once when the ship goes out of the channel limits.
Before the alarm was reactivated every 5 minute. NOTE the permanent indication of "OUTSIDE CHANNEL"
operates as before and give always an indication of route tracking status.
Past Tracks
Own ship has now three separate past tracks:
• "System", which is the past track of the system position used for navigation and steering.
• "Primary", which is the past track of a position sensor selected as Primary.
• "Secondary", which is the past track of position sensors selected as Secondary.
Speed Vectors
• There is now a selection between true and relative speed vectors for own ship and ARPA targets. Before only
true vectors were available.
Page 18
2 •••• Changes since release 02.01
Radar echo overlay
• There is now a selection between true and relative radar echo trails. Before only relative trails were available.
Details log
• details log for last 12 hours include now course over ground and gyro correction in order to provide more
complete recording
Chart related changes
S57 and ARCS charts
• chart display has more alternatives to individually select visibility of different text on chart
• Info Request has now transparent area fill for better indication of the area in question
• Info Request show now the coded text for each picked object. Before only attributes and their values were
available. This change eases for example usage of light descriptions.
S57 Chart
• Chart Catalogue uses colour coding to indicate up-to-date chart and non up-to-date charts.
• Telecomm order of Charts and updates open now automatically "Order queue window" and inform the user
about end of orders when all requested transactions are complete.
Steering related changes
Goto Track steering mode requires Kalman filter and a high precision position sensor such as DGPS, new alarms
related to it are:
• alarm "2491 Disabled: Needs diff pos."
• alarm "2492 Route: Needs diff pos."
Program Track Turn steering mode requires Kalman filter and a high precision position sensor such as DGPS, new
alarms related to it are:
• alarm "2493 ProgTurn: Needs filter ON."
• alarm "2494 ProgTurn: Needs diff pos."
• alarm "2495 ProgTurn: Needs log sens.."
Display of curved EBL shows correctly "program course changes" of more than 180 degrees.

The ECDIS uses S52 standard presentation for all non chart objects. Both S57 and ARCS uses S52 standard
presentation. User can check the used presentation library from both S57 and ARCS: Chart Plan - System - S52
Presentation library. The reason for changes has been ECDIS type approval requirements together with legal
presentations defined in ECDIS type approval standards. As a consequence following non chart object has
significantly changed presentation:
Object Old presentation New presentation
User Chart Line features Various blue lines Various dark yellow or red lines.
Red is used if the Line is set as
dangerous.
User Chart Area features Transparent blue area with blue line
around

end of speed vector which indicates
water or ground stabilisation.
Nav Mark VRM features Two different line styles of orange
colour - one for first VRM and
another for second VRM
Theoretically two different line
styles of orange colour as before,
but because of drawing rules
defined in ECDIS standards they
are both presented normally as
dashed lines.

Voyage planning
Voyage planning is a preparation phase for coming voyage. Preparation includes route definition, ro ute calculation
and optimisation.
Required sea charts are also prepared in voyage planning either by updating existing charts or creating new ones.

Route Planning
Modification an existing route or creating the whole new route is the way to do Route planning.
1. Definition of route consists following:
• Position of each waypoint
• Turning instruction for each waypoint
• Safety limits between waypoints (channel limits)
• Safe water calculation based on Safety limits
• Required steering accuracy for individual leg
• Speed restrictions for a leg
2. Information notebook
• Information pages to alert operator at a given waypoint or in the selected area.
• Automatic and/or manual notebook function to tell operator position based information.
3. Voyage optimisation parameters.

Navigation Tasks •••• 19
Route Calculation
Route calculat ion for voyage planning includes following:
1. Route pro file calculation
• Distance between consecutive waypoints
• Course between waypoints
• Calculation of wheel over point
• Total distance
• Estimated time for voyage
2. Route check
• Grounding alarm based on available depth information in digital chart data base
3. Voyage optimisation
• Time table optimisation
• Optimisation based on economical factors
• The ECDIS processor calculates optimum speed and course between each waypoint,
ETA and fuel consumption, based on the defined data. There are 4 calculation
strategies: Max. Speed, Timetable, Lowest Cost and Best Profit. In case of great circle
sailing between two waypoints the ECDIS calculates max. and min latitudes and if
needed adds an extra waypoint not to go over min or max. latitude.
Chart planning
1. Loading of new S57 and ARCS charts
2. Updating on existing S57 and ARCS charts
3. Handling of chart permits
4. Manual update
User Chart planning
1. User generated navi gation charts
2. User defined chart alarms based on symbols, lines and areas of User chart

ECDIS Screen
Overview
Parts of the ECDIS display.
The ECDIS (Electronic Chart Display and Information Systems) screen includes several areas. There is statusbar at
the top and the bottom of the screen, which are shown permanently. The upper and lower right hand corner is taken
up by permanently shown in Information area. Between these areas there is a Dialog box area where user can fill or
choose appropriate options. The left hand part of the ECDIS screen is the Electronic chart area. When the push
button is pressed from the Control Panel appropriate menu opens up at the current cursor's location.
Page 42
26 •••• ECDIS Screen
Electronic chart area
The ECDIS can use the following types of charts:
• S57ed3 ENC charts (vector)
• CM-93 charts (vector)
• ARCS charts (raster)
There can also be displayed following information:
• cursor moved by trackball
• planned ro ute
• EBL (Electronic Bearing Line) and VRM
• symbol of ownship with speed vector
• targets acquired by ARPA
Electronic charts in ECDIS
The electronic navigational charts are displayed in Electronic chart area. There are two kinds of electronic
navigational charts available to use in the ECDIS:
• S57ed3 ENC or CM-93 vector format
• ARCS raster format
S57ed3 ENC and ARCS electronic charts may substitute official paper charts. User should check the current
situation from his flag country administration and if in doubt use the paper charts as primary source of navigational
information.
ECDIS combines chart and navigational information. It should be noted that modern navigation systems (e.g.,
differential GPS) may offer a more accurate positioning than was available to position some of the surveys from
which the electronic navigational chart was derived.
S57 vector format:
ECDIS is compatible with S57 release 3 ENC format. From this format the ECDIS generates the “System ENC”, =
SENC, which is used for actually for operatio ns the ECDIS.
When opening a chart it is displayed with default scale called compilation scale. It is possible to modify details of
chart displayed in Electronic chart area. You can change scale of chart by pressing ZOOM IN and ZOOM OUT
pushbuttons. Scale range is 1:1 000 - 1:50 000 000.
CM-93:
Compatibility with CM-93 format depends on commercial agreements. Some versions of this ECDIS are compatible
and others are not. The compatibility is controlled by the security device called dongle. From CM-93 format the
ECDIS generates SENC which is used for actual operations of the ECDIS. The difference between S57ed3 ENC
charts and CM-93 charts is that the CM-93 charts are from a private source and they cannot be used as a substitute of
paper chart under any condition. To highlight that part they are later called as NON-HO charts in this manual.
Page 43
ECDIS Screen •••• 27
Display of S57 chart on ECDIS screen
ARCS raster format:
ARCS charts are digital reproductions of British Admiralty (BA) paper charts. They retain the same standards of
accuracy, reliability and clarity as paper charts.
Zooming into the ARCS chart can be useful for magnifying complex detail, but decreases the density of data
displayed, and can give a false impression of distance from danger. Therefore it is possible to zoom 2*original paper
chart's scale or ½*original paper chart's scale.

current paper chart.
Once you have selected a datum, all numerical latitude-longitude position values are presented in your selected
datum.
Note: If you use ARCS raster chart material the rasterized charts contain some rasterized position information.
These positions like scales in the edges of ARCS charts are true only if you have selected native datum of that ARCS
chart. Normally this is the natural situation, because you use ARCS together with equal official paper chart and
because you have selected as datum the datum of your equal official paper chart.
To select datum proceed as follows:
1. Press Initial setting push button.
2. Select desired datum from a list box of Datum.

Introduction
Carriage requirement for adequate and up to date charts for intended voyage can be found from SOLAS Chapter
V/20 of the 1974. In resolution A.817(19) IMO has specified how requirement of the V/20 of the 1974 can be
fulfilled with a device called ECDIS. In resolution A.817(19), Appendix 7 (RCDS 1998) IMO has specified how
requirement of the V/20 of the 1974 can be fulfilled when an ECDIS uses RCDS mode. The traditional alternative
way to fulfil requirements of the SOLAS chapter V/20 of the 1974 has been the use of paper charts.
If you use type approved version of this ECDIS (BSH type approval certificate number 6579 / 080 138 / 99. If in
doubt, contact your supplier of the ECDIS to check the status of your system) and if following conditions are met,
then your system fulfils IMO A.817(19).
• own ship area is covered with updated ENC charts
• your selected display area is covered with updated ENC charts
• you have a backup system which fulfils IMO A.817 requirements. One example is a second
ECDIS
Note that ENC producers provide their conditions of use in the Publisher notes, which you should read always when
loading new material into the ECDIS. See chapter "How to load S57 charts from " on page 56
In areas where ENCs are not available raster chart material called ARCS from UK HO can be used in the ARCS
mode of this ECDIS, if following additional conditions are met:
• own ship area is covered with updated ARCS charts
• your selected display area is covered with updated ARCS charts
• appropriate folio of up-to-date paper chart is carried onboard and available, if required by your
flag country administration

How to detect ENC coverage in S57 Chart display
This Electronic Chart System has capability to show more than one S57 Chart cell at the same time. This feature is
called multi cell display. If one S57 Chart cell does not cover the whole display the system will open more S57
Chart cells to be displayed, if they are available in displayed area. The Upper Status bar shows information about
S57 Chart cells displayed on the Electronic chart display area. The information depends on position of cursor.
The list of possible indications:
RCDS mode: Raster chart material is displayed on electronic chart display area.
Non ENC Data: The S57 Chart at cursor location is not official ENC material.
No indication: The S57 Chart at cursor location is official ENC material
Areas which are covered by legal ENC data are indicated with ENC coverage symbol. See following examples.

Vector Chart material
Introduction
Theoretically a chart can be coded for computer as raster or vector chart. There is a special chapter for raster coded
charts in this manual. Vector coded charts can be coded using different techniques. One technique is called S57ed3
and this technique has been selected by IMO as the only alternative for SOLAS compliant electronic charts. If a
S57ed3 coded chart is published by government authorised Hydrographic Office, then it is called ENC. If a S57ed3
coded chart is published by private industry, then it is called as NON ENC. Another technique is known as CM93/2. It is used by private company C-MAP to publish electronic charts. All CM-93/2 charts are NON ENC. There
is a special chapter about C-MAP charts in this manual. You can read more about ENC and related legal issues in
chapter "Conditions required to replace paper charts". Later in this manual all references to Vector Chart material
are under name S57 Charts regardless of the source of them.
Sometimes you may wish to add manually Notices to mariners or Navtex warnings into your S57 charts. In this
system this kind of things are called as Manual Updates. Manual updates are valid for both S57 and ARCS charts so
that you need to define them only once. Also manual updates are valid for all scales so that you don't need to repeat
them for charts published in different scales from the same area. See more details in chapter "Manual Updates" .
S57 Charts
Introduction
This Electronic Chart System is compatible with official IHO S57 release 3 chart material produced by
Hydrographic offices (HO). This material, when issued by government authorised Hydrographic Office, is called
ENC (electronic navigational chart). Use, presentation and display of S57 charts are based on International
Maritime Organisation (IMO), International Hydrographic Organisation (IHO) and International Electrotechnical
Commission (IEC) regulations and rules (S52ed3.1). When this ECS (Electronic Charts System) uses ENC (S57
release 3 chart produced by a government authorised Hydrographic Office), it is an ECDIS as defined by IMO, IHO
and IEC.
An ENC could be encrypted to prevent unauthorised use and then the user needs a permit to view the ENC. This
permit could be entered manually from control panel, loaded from a floppy disk or loaded through
telecommunication from a RENC.
Before any ENC can be used in the ECDIS, it is loaded into the hard disk and converted into the system’s own
internal format (SENC). Some parts of the charts may be date dependent i.e. they are visible after a set date or they
are visible only for a limited period etc. In this Electronic Charts System you control all date dependent objects with
Display Until and Approve Until dates. In paper chart world the Preliminary and Temporary Notices to Mariners
represent the date dependency described above for S57 charts.
An important part of ENCs are the updates. Hydrographic Offices can issue two kinds of updates:
• incremental updates, which are small additions to original base cells
• reissues and new editions, which are complete replacements of previous base cells and their
updates
All updates are date stamped and they may also contain date dependent parts. You control also usage of updates in
this Electronic Charts System from Display Until and Approve Until dates. Using Display Until and Approve Until
dates you can view your charts correctly drawn on any date in the past or in the future.
Page 67
Vector Chart material •••• 51
Chart material will be available stored in media such as CD-ROMs and floppies, electronically through
telecommunication from RENCs or electronically from LAN (Local Area Network) in which it could have arrived
from RENCs, CD-ROMs or floppies. Such material can contain only basic cells, cells and updates or only updates.
This Electronic Chart System contains as standard delivery the software to access CD-ROMs, floppies and LAN. A
telecommunication package to establish a connection to the RENC in Stavanger, which operates using marketing
name PRIMAR, is available as an option.
Each S57 chart may contain beside the chart itself links to additional textual descriptions or pictures. T ypically
additional textual descriptions and pictures contain important sailing directions, tidal tables and other traditional
paper chart features, which do not have any other method to be included into the S57 chart. This ECDIS copies
these textual descriptions and pictures into its hard disk and allow you as user to cursor pick them for viewing
purposes.
An appendix of this manual provides short introduction for interpretation of S57 ENC chart display.
Definitions of terms
Cell
A cell is a geographical area containing ENC data. Each cell has separate unique name.
Hydrographic Offices divide their responsibility area into the cells which they publish.
S57 chart
A database, standartized as to content, structure and format, issued for use with ECDIS withou
t
any authority of government authorized Hydrographic Office. The difference of S57 chart and
ENC is that non-ENC charts require complete up-to-date paper charts to be used as primary aid
of navigation.
ENC
A database, standartized as to content, structure and format, issued for use with ECDIS on the
authority of government authorized Hydrographic Offices. The ENC contains all the char
t
information necessary for safe navigation and may contain supplementary information in
addition to that contained in the paper chart (e.g. sailing directions) which may be considered
necessary for safe navigation. The name of coding standard for ENC is S57ed3.
SENC
A database resulting from the transformation of the ENC by ECDIS for appropriate use,
updates to the ENC by appropriate means, and other data added by the mariner. It is this
database that is actually accessed by ECDIS for the display generation and other navigational
functions, and is the equivalent to an up-to-date paper chart. The SENC may also contain
information from ot her sources.
RENC
A service provider offering ENC delivery and update service as defined in IHO standard
S52e3. Often a RENC provides both CD-ROM and telecommunication based service to
ECDIS users. One example of a RENC is the RENC in Stavanger operating under marketing
name PRIMAR.

Chart legend of S57 chart
CHART LEGEND is not a pushbutton, but it is a front-page, which is displayed as a base. If you push CANCEL
enough you will finally get CHART LEGEND.
This system is capable to show more than one S57 Chart at the same time. This feature is called multi chart display.
If one S57 Chart does not cover the whole display, the system will open more S57 Chart to be disp layed, if they are
available in displayed area. The Chart Legend shows information about S57 Charts displayed on the Electronic chart
display area. The information is available always from the current position of the cursor.
Cell name:

Permanent warnings of S57 charts
Permanent warning help you to keep the S57 charts up-to-date. Only up-to-date S57 charts can be legal replacement
of the paper charts. Permanent warnings indicate, if the system detects a condition which may cause your system to
use not
up-to-date charts.
NOTE! The system can powerfully assist you to keep your charts up-to-date for the charts which you have got from
a RENC. For charts which has been loaded from other sources than a RENC, the system is unable to know the exact
up-to-date situation.
See more details in chapter "Date dependent and
periodical features of Vector chart".
You have loaded updates into the hard disk, but these
updates are not included into the SENC. This kind of
charts are drawn in orange colour in the Chart Plan Catalogue.
Perform SENC conversion for these charts. See
more details in chapter "How to use SENC convert
window to initiate SENC conversion".
See more details in chapter "How to know up-to-date
status of the RENC Product List".
You have loaded an update which contained cancel
information for a chart. You selected not to remove
the canceled chart. This permanent indication
reminds you about your intended use of a canceled
chart.
Consider removal of the chart. See more "How to
remove S57 Charts from the system" on page 79.

How to load S57 charts from a CD-ROM, floppy or LAN
When you load S57 charts by CD Catalogue, the system first load a CD catalog, which stores certain information
into the hard disk such as cells ID, their position, edition number, from your LAN (Local Area Network) connection,
floppy or CD-ROM. After that the system asks which charts will be loaded from the selected media.
After building the CD catalogue you can view the contents of it using S57 catalogue command.
Note: All CD-ROMs, floppies or LAN (Local Area Network) connections from one single National Hydrographic
Office have equal names although thei r contents could be totally diffe rent. Y ou can use your o wn unique names to
identify them separately and correctly later.
To load by CD catalogue proceed as follows:
CHART PLAN push button
1. Press CHART PLAN push button.
2. Select Load from the menu and by CD Catalogue from the sub menu. A
S57 Load dialog box appears. The default load source is CD-ROM. Press
Load and continue from step 5, if you use CD-ROM. If you want to load
from a floppy disk or from another ECDIS using LAN, you have to change
Load Dir. Press Browse to select a new Load Dir
3. If you use a floppy disk, select A:\ in Drive:. If you use another ECDIS using LAN, select suit able Drive: and
Sub Dir. Note that a correct load source has "\ENC_ROOT" in the end of the Current Directory: (see
example below).
Press Select when you are ready.
Page 73

4. You return back to S57 Load dialog. Press Load .
Note, if you are loading PRIMAR official ENC service Base CD or Update CD, the ECDIS will automatically
give name "PRIMAR" or "PRIMARUPD" for CD Catalog and you can continue step 7.
5. A keyboard dialog box appears. Enter name for CD Catalog and press OK. System will load catalog
information into the hard disk.
6. The system automatically copies all Text and Pictures files associated with Charts from a CD Catalogue. The
system keeps only the latest version of these. If your system had already in use newer Text and Picture files you
will get the notice below.
Page 74
58 •••• Vector Chart material
7. Following dialog box appears
Select a named "CD" you want to load from CD -field. A list of charts appears into a list box which contains
information about charts (edition and update number). In a Chart Selection you can choose, which charts are
loaded from the CD-ROM. Selection "Missing only" loads only Charts and their updates which are not already
loaded into the ECDIS.
Note, If you want to remove loaded CD Catalogue, select desired CD from the list box and press Remove
button.
8. Press Load button to load selected charts.
9. If any of chart conversion fails, a Failed SENC conversion window appears, which has a list of failed
conversions. Use this window to find out the reason for failure. For more information, see chapter " How to use
Failed SENC conversion window" on page 65.
10. If you want to view the progress of SENC conversion, you can activate the SENC convert window. For more
information, see chapter "How to view progress of SENC conversion" on page 64
NOTE 1! If you want to make chart selection by group , pr e ss Group button and select desired group. If in selected
group and list of charts have common charts, they are highlighted in the list box.
NOTE 2! If your system has LAN (Local Area Network) and you want load your charts from another drive than
your system CD-ROM drive, press Source Dir button. Then you can define drive and path from where you load
your charts.
NOTE 3! The System can make conversion into the SENC and set the "Display Until" date automatically. This is
the recommended way. More information to set them, see chapter "How to select automatic SENC conversion and
Display Until date" on page 63.
NOTE 4! You should read the text file associated into each catalog. The text file typically contains very important
notices for the usage of the charts from the producing Hydrographic Office.
1. Press View CD Publisher Notes button in the S57 Load dialog box.
2. A viewer shows you the Publisher Notes of the selected "CD".
3. If you want to make a hard copy of Publisher Notes, select Print in the File menu.
4. To close this program, select in Exit in the File menu.

NOTE 5! You can view the Summary of the content of the CD. It contains information about charts you are going
to load.
1. Press View CD content Summary button in the S57 Load dialog box.
2. A viewer shows information about the selected "CD". Each row contain:
• CellID Name of the chart
• Edition Edition number of the chart
• Base Included update number and issue date of base cell of the chart
• First Update Update number and issue date of the first update included
• Last Update Update number and issue date of the last update included
3. If you want to make a hard copy of the Summary of Catalog, select Print in the File menu.
4. To close this program, select in Exit in the File menu.
The example above contain only base cells and reissues of the charts. Charts GB204000 and GB50401S are called
as reissues, because they already include updates (GB204000 include updates 1 and 2. Gb50401S include update 1).
Charts GB304010, GB40401S and GB40501L are called as base cells, because they do not contain any updates i.e.
their update number is 0.
The example above contain both base cells and all updates of the charts from issue of base cell up to the last update.
The example above contain only updates. In example above update 3 is available for chart GB204000, update 1 is
available for chart GB40401S, updates 1 and 2 are available for chart GB40501L and update 2 is available for chart
GB50401S.
Messages, which control reload
If you try to load charts with the
same edition already loaded into your
hard disk or if you try to load the
same update already loaded into your
hard disk, you get following
messages after pressing Load button.
If you press Cancel button, you will
get following dialog box:
If you want to avoid very time consuming reload of charts which you already have, then you should select No (="No

However if you want to reload charts, then select Yes (="Yes for all" option in above window).
Messages, which contain only notice
If you tried to load older chart data than you already have in your hard disk, you will get one of the following
messages:
This indicates that you already use a
newer edition of the chart.
This indicates that you already use a
newer reissue of the chart, which
includes this update
.
This indicates that you already use a
newer reissue of the chart
.
This indicates that you already use
these updates
.
NOTE! You can not replace chart data, which is already in use unless you only replace the latest base cell or update.
If you want to reload older data again, you must first remove the chart from your hard disk (See chapter "How to
remove S57 chart cells from the system").
Messages, which require careful attention
All messages in this chapter change the legal status of the charts in your system. Study these message extremely
careful because you may need to use paper charts to fulfil SOLAS requirements
Test before ENC to SENC conversion fails
CRC checksum is tested before the

hard disk, you will get following
message:
The message above clearly indicate that this chart is not up-to-date and thus it does not fulfil SOLAS
requirements. Get immediately from the publisher of this chart the new edition of the chart.
You do not have all the published updates
If you tried to load updates and you
miss one or more updates between
updates already loaded into your hard
disk and updates that you are
loading, then you get following
message:
The message above indicates that you tried to load updates number 3, 4 and 5 when at least update 2 and possibly
update 1 were not available in your hard disk. Check the content of your CD-ROMs to find the missing
update/updates or contact your chart supplier.
The message above clearly indicate that this chart is not up-to-date and thus it does not fulfil SOLAS
requirements. Get immediately from the publisher of this chart the missing updates of the chart.
Unsafe Chart has been cancelled by the publisher
If you load an update, which contain
cancellation of the chart instruction
by the publisher of it, you get
following message:
Normally you should accept the cancellation and you should press Yes. Then the system automatically removes the
chart from the hard disk and from your chart screen.
You may insist to keep the cha rt although the publ isher of it has told you that the content of the chart is so unsafe
that they have cancelled it. The reason might be that you do not have anything better available. In this case you
press No. Then the system automatically remove the ENC status from the chart, because the publisher has told so in
his special cancellation update.
Note that the cancellation message above clearly indicate that the publisher says that this chart is unsafe for
navigation and thus it does no t fulfil SOLAS requirements. Get immediately from the publisher of this chart the
new chart/charts, which replace the unsafe cancelled chart.

How to load S57 charts, which are not fully compliant with the
standards
The ECDIS could in some cases load S57 charts, which does not have full compliance with S57 standard coding for
transfer media. Minimum requirement for loading manually is legally coded:
• XXXXXXXX.000 file, which includes a base cell
• XXXXXXXX.NNN file, in which NNN is a number from 001 to 999, and which includes an
update
To load charts without building a named "CD Catalog" proceed as follows:
CHART PLAN push button
1. Press CHART PLAN push button, sele ct Load from the menu and Manual
from submenu.
2. You can select desired drive and charts.
When ready to load charts, press Load Chart button.

S57 SENC Conversion details
S57 charts from Hydrographic offices are called ENCs. An ENC has to be converted into SENC format before it can
be used in the ECDIS. The ECDIS can convert ENC into SENC format automatically. If the conversion is
successful, the Failed SENC conversion window does not appear.
If the system fails to convert ENC into SENC or if the system detects an coding error in an ENC, a Failed SENC
conversion window appears with a list of failed ENCs. In this window you can select any of the charts to see reason
for failure in conversion.
Normally the conversion is initiated automatically from loading of the charts. Chapter "How to load S57 charts" on
page 54 describes the loading process. Chapter "Ho w to select automatic SENC conversion and Display Until date"
on page 63 describes how you can select automatic conversion. You can also initiate conversion from a SENC
convert window or from a Cell Status window.
How to make SENC conversion faster
The SENC conversion speed depends about how many other tasks the system has. The system can do SENC
conversion as background process during any other possible operational use of the system, but you can greatly
improve the speed of the SENC conversion, if you do following things:
1. Disable Radar echo overlay. Select Radar overlay mode as ECDIS ONLY. Select co ntr ol o f visib le naviga tio n
features as OFF for Radaroverlay (the Radaroverlay visibility control is located in "Tracking" sheet of " Chart
details").
2. Select Display Mode as TRUE MOTION
3. Press Set Chart Center push button and allow the system to operate either in TM RESET OFF or SHIP OFF
SCREEN state
4. Press Zoom In until you reach scale of 1:1 000
How to select automatic SENC conversion and Display Until date
When you are loading new S57 charts base cells and/or their updates into hard disk, it is possible make automatic
conversion to SENC format. It is also possible to set display dates as issue dates automatically. Proceed as follows
to set these options:
1. Press CHART PLAN button, select SENC Convert Settings from the menu.
2. A S57 Settings dialog box appears:
Select Automatic SENC Conversion and Automatic Display Until options.

How to use Failed SENC conver sion window
If the system is unable to convert ENC into SENC without any error or failure, a Fa iled SENC conversion window
appears with a list of failed ENCs. Status of Failure means that the system completely failed to convert the ENC into
the SENC and thus the ENC cannot be used.
Status of Errors means that the system detected minor or major errors in the conversion of the ENC into the SENC.
Check carefully the content of Conv history and Cell status to see, if the error was minor or major. Major errors are
indicated as NON ENC in Conv History. Note that the status of Errors together with NON ENC in Conv
History clearly indicate that this chart is not up-t o-date and thus it does not fulfil SOLAS requirements. Get
immediately from the publisher of the chart the new edition of this chart.
Status of Failure means that the system completely failed to convert the ENC into the SENC and thus the ENC
cannot be used. Note that the status of Failure clearly indicate that this chart is not up-to-date and thus it does
not fulfil SOLAS requirements. Get immediately from the publisher of the chart the new edition of this chart.
The Failed SENC conversion window conta ins two buttons. One to open conversio n history log Conv. History
and another to open Cell Status window of selected item in the list of Failed SENC conversions window.
If you use Conv. History button, a
Conversion Log appears. Conversion Log
shows the status of converted ENCs. More
information about the results of conversions,
see chapter "How to use SENC Conversion
history log" on page 66.
If you use Cell Status button, a Cell Status window appears.
Then you can push Conv Log button to open view detailed description of errors and failures detected during SENC
conversion (see example on next page.
In the example above the reason of the SENC conversion failure is a miss match of checksum (calculated crc number
differs from the expected).

requirement that you have included the latest update into your chart. You must refer to a paper chart as legal
primary aid of navigation, when you navigate in the area covered by this chart.

Failed conversion. The base cell has failed in its SENC conversion
The system cannot accept updates unless the base cell has been successfully converted into the SENC. Chart is not
usable and you cannot view it. Try to reload the base cell from original media (in this example the failed base cell is
GB5X01SW.000). And if that doesn't help order a new CD-ROM from your chart supplier. You must refer to a

NOTE! Always study both the "Failed SENC conversion" dialog and "Conversion history
log" very carefully, because they contain important information about the legal status of
the charts. Specially note that a chart may lose its legal status to fulfil SOLAS
requirements and you may need to refer to a paper chart as legal primary aid of
navigation.

How to use SENC convert window to initi a te SENC conver sion
Normally the "Automatic SENC conversion" is selected and there is no need to initiate SENC conversions from the
SENC convert window. If you do not use the "Automatic SENC conversion" , you need to manually initiate SENC
conversion. Another case in which you need to manually initiate SENC conversion is, if you upgraded or reloaded
the ECDIS software from the ECDIS software CD-ROM.
To initiate SENC conversions manually proceed as follows:
1. Press CHART PLAN button, select SENC Convert from the menu.
2. A SENC Convert window appears:
3. Use Cells to select an individual chart or use Groups to select a group of charts.
Then press Convert to initiate the SENC conversion of the charts. Note that the
Convert only do conversion of those charts, which are not currently converted into
the SENC format. If your selected chart or all members of your selected group are
already in the SENC format, the Conversion list remains empty. If all or some
charts are not yet in the SENC format, they are added into the Conversion list (see
example below). If you need for some reason to force SENC conversion of an
already converted charts, you read instructions in chapter "Seldom used features o
f
Vector charts" on page 144.
Note 1!. You can at any moment remove charts from the conversion list. You pain
t
with the cursor any amount of chart names in the Conversion List. And then you press
Cancel Conv. to remove your painted charts from the SENC conversion queue.
Note 2!. You can at any moment view the results of the finished SENC conversions.
Press Conv. History and you get a Conversion log for viewing.

Introduction to the S57 chart service from a RENC
Introduction
Before you can use RENC service, you have to be authorized as Customer of RENC. To be authorized you have to
contact official distributor (Chart Agent) of RENC. After that you have available following services:
• CD-Service
• Telecomm Service
You can use either CD-Service or On-line Service alone, or you can use some combination of services, like order of
Product List, Permits, Updates by Telecomm Service and Base Charts by CD-Service.
Permits
Permits are used to control the permission to use a chart. A permit in RENC security is connected to an edition.
Permits are issued as two different types
• Subscription Permit. These include updates for subsequent 12 months. It is assumed that a typical user is a
SOLAS class vessel, which is required to use up-to-date charts.
• One-Off Permit. These include only updates up to the issue date of the Permit. It is assumed that a typical user
is a non
-SOLAS class vessel, which is not required to use up-to-date charts.
Each Permit includes also the expiry date.
The expiry date of a Permit controls the ENC to SENC conversion. If the issue date of a chart or update is older or
equal to the Permit expiry date, then the system can convert an ENC into the SENC. There are no viewing time
limits as used in some other security systems such as ARCS. The user has a right to view a chart forever and more
over he has a right to convert a chart from its ENC format into the SENC forever.
A RENC can publish Permits in two different formats
• “*.pmt” format. T hi s fo rmat d o es no t
include the applicable chart edition and does not include applicable permit
type.
• P ERMIT.T XT format. This format does include the applicable chart edition and d oes include applicab le permit
type.
Both permit formats are fully operational, but the older “*.pmt” format creates confusion, because it cannot support
the user, when chart edition changes.
The system display warnings associated with expiry date. Examples are “will expire” warning 30 days before the
expiry date and “have expired” after the expiry date. These warning are relevant only for Subscription Permits.
Only the new PERMIT.TXT format support the system to suppress irrelevant warning associated with expiry date.
Product List
A Product List is maintained by a RENC. You can retrieve the Product List by Telecomm from a RENC or you can
load it from the CD-ROM of a RENC. This list contains an up-to-date list of available charts and their
edition/update status in the RENC. When you load a CD-ROM or use Telecomm to receive Product List from a
RENC, the ECDIS checks the issue date of the Product List. If the issue date indicates newer Product List, then it is
copied into the ECDIS. If the issue date indicates older Product List, then ECDIS shows a notice to the user that
newer already loaded.
Authentication
Normally the authentication process is invisible for the user. Only if the Authentication fails, then the user gets
appropriate no tice. From user po int of view the Authentication is similar to CRC checksum test. If CRC checksum
test or Authenticat ion fails then the chart is unusable.
Authentication uses private key and public key. A digital signature associated with each chart contains private key.
Public key is stored in the ECDIS and it is really public. RENC may publish a new public key. This public key will
be available as text by fax, by post, by front page of a newspaper etc. and as a text file called for example
PRIMAR.PUB. The day, when a RENC publish a new public key, will be similar milestone than the change of
millennium.

Available service types
Telecomm Service
Telecomm Service is using telecommunication lines to retrieve information from the RENC. Following information
can be downloaded there:
• ENC Product List
• Information, status and coverage of all available ENC products
• Cell Permit
• B uy decryption permit to access the ENC information
• ENC Information
• Download ENC base cells or updates
CD-Service
If you are using CD-Service, you receive from the RENC following:
• B ase CD contain all Base Cells that are available in the RENC database when CD was released.
• Up date CD contain all updates to the Base CD, but it will also contain any new Base Cells and New Edition, Re-
issues received from the contributing Hydrographic Offices. Update CD will be issued once a week.
If you want to enlarge your chart coverage, you have to contact your Distributor to order more permits for new
charts.
Subscription types
Charts and their Updates stored in RENC are decrypted and you have to get key (Permit) to load chart into the
ECDIS. There are two different kinds of Permit to choose suitable one for your purpose.
Subscription
Subscription period is 12 months and it starts when you order first Permit(s) from the RENC.
• User subscribes to a updating service
• Updating service has a renewable expiration date
• ENC is still available after expiratio n, b ut can not apply any new information
• User will receive during the service period:
• all updates issued to the ENC
• any re-issues for the ENC
• any new edition of the ENC
If you enlarge your chart coverage during your subscription period as shown above, will expire date of subscription
for all charts be the same date.
One-Off
If you use One-Off Permit, you order permit for chart and updates which are valid until date you order permit (i.e.
Chart is up-to-date when you ordered it). No more information can be retrieved for this chart, which is published
after order date.
One-Off Current Edition; permit for a chart, which is based on data on the hard disk of the ECDIS.
One-Off the latest Edition; permit for a chart, which is the latest available based on the Product List of a RENC.

How to view the Coverage of the RENC service
Whenever you like to see Product List in graphical presentation, use Catalog to view it. The Catalog of S57 Chart
shows the situation when you last time ordered the Product List from the RENC or loaded the latest BASE or
UPDATE CD-ROM into the ECDIS.
Note, the ECDIS keeps automatically the latest available Product List. Thus the ECDIS do not load the Product List
if it is older than already loaded into the ECDIS.

The chart is available either in ENC format, in SENC format for another software version or in SENC
format for another ECDIS. For example chart is blue during SENC conversion and if you loaded a
chart into the ECDIS and the system could not convert the chart into SENC format.
Magenta
You have a permit to use the chart, but the chart is not available in SENC format and thus you cannot

How to know up-to-date status of a chart from a RENC
To keep Charts up-to-date you have to check situation in a RENC about at weekly basis. The ECDIS compares used
charts to Product List of RENC. If a Permanent Warning appears to Chart display of ECDIS, it is an indication
that at least one of used charts is not up-to-date compared to the Product List, see below:
The information of available charts and their up-to-date status is available both in Catalogue and in Date Dependent
window.
The easiest method to check up-to-date status is to view Catalogue and check that all required charts are
indicated as green. Charts which are not
up-to-date are indicated as orange. See more "How to view the
Coverage of the RENC service" on page 82.
You can also use Date Dependent window on demand when you have doubt that some charts are not up-to-date or
you have the Permanent Warning shown above.
