Purpose of this Guide
ENCs contained within the Admiralty Vector Chart Service (AVCS) are produced and distributed
according to well-defined international standards. However each ECDIS manufacturer has
implemented the ENC import module differently. Users who are experienced in operating a particular
model of ECDIS may require additional supporting information when managing AVCS ENCs on
ECDIS equipment that they are not as familiar with. The purpose of this guide is to provide
equipment-specific information to assist users in managing their AVCS ENC holdings.
This guide has been produced to take users through the installation of AVCS on ECDIS or ECS
equipment. The actual instructions and screenshots are based on the version of the ECDIS installed
at the UKHO as detailed on the front cover. However the method of managing AVCS and other digital
data, e.g. ARCS, is common across equipment supplied from the same manufacturer, i.e. different
versions and models. There may be minor differences between certain models and these will be
highlighted in this guide where known.
AVCS User Guides are available for other ECDIS equipment; please visit www.ukho.gov.uk/AVCS to
download a guide suitable for your ECDIS equipment.
This guide should be read in conjunction with the AVCS User Guide, as well as the ECDIS Operators
Manual or other documentation as supplied by the equipment manufacturer.
Your Admiralty Chart Agent will provide you with the following materials when you subscribe to AVCS
for the first time:
AVCS Start-Up Pack
AVCS Quick Start Guide;
AVCS User Guide;
AVCS Base Discs (a set of CDs or a DVD labelled ‘Base’);
AVCS Update Disc (a CD labelled ‘Update’)
Admiralty Utilities installation CD;
Admiralty Digital Data Services End User Licence Agreement (EULA).
AVCS Licence
This may be supplied with the AVCS Start-Up Pack on hard media, e.g. floppy, CD, etc. or separately
by e-mail. The initial licence pack will contain the following:
A “Schedule A”, this is a PDF document listing the Folios and ENC Units that the user is licensed
for. It also lists the “Home CD” where the licensed ENCs are held. This is particularly useful as it
prevents unnecessary loading of those CDs that do not contain any licensed ENCs.
A set of ENC Permit files (PERMIT.TXT and ENC.PMT) for each ECDIS installation.
AVCS Certificate (a PDF document showing your vessel and license details).
1
;
For an initial installation, or a reinstallation of AVCS on a purged ECDIS you will need all of the above
materials. If you are applying a weekly update, you will only need the latest AVCS update disc and
possibly a new ENC Permit file. If you want to install additional coverage on the ECDIS you will need
the latest base disc(s), the latest update CD and a new set of ENC Permit files.
AVCS Material Replacement
Most Admiralty Chart Agents will have a stock of AVCS Start-up packs, so base and update discs can
be obtained from them. Usually digital files, such as ENC Permits, are sent as attachments to emails
and these may be stored in your email system’s inbox. If not, your Chart Agent will often hold copies
of any permit files previously sent to you.
Pre-installation Checks
Data Cleansing
New AVCS customers who had previously subscribed to other ENC services are strongly
recommended to remove (purge) all ENC Permits and ENCs from the system before installing AVCS.
There is a good reason for doing this as previously installed ENCs may become out of date if they are
not licensed in AVCS. If the system is not purged redundant ENCs may remain in the system
database (SENC) and be available for use, even if the previous license has expired. However
unlicensed ENCs cannot be updated and the user may be unaware of this if inadvertently navigating
on one. Instructions on how to remove ENC Permits and ENCs are described later in the
Cleansing section.
Data
1
Currently an AVCS Update CD will not be available if the customer joins AVCS coincidentally with a re-issue of
the AVCS Base CDs. This may change in the future with the incremental issue of the AVCS bases.
The ECDIS will not install ENCs from AVCS unless the correct Public Key is installed. If the correct
Public Key is not installed the ECDIS will report an Authentication Failure.
Background
The ECDIS authenticates the source and integrity of encrypted ENCs from Service Providers against
a pre-installed Public Key. The Public Key can be formatted in one of two ways, either an ASCII text
file (.PUB) or an X509 Certificate (.CRT). Newer ECDIS (manufactured since 2003) often come with
the IHO.PUB and/or IHO.CRT pre-installed as the IHO are the Scheme Administrator (SA) for the S63 ENC Data Protection Scheme. The UKHO is a certified subscriber to this scheme. However, for
historical reasons, it does not use the IHO Public Key. AVCS ENCs are currently authenticated
against the PRIMAR Public Key. The reason for this being that many legacy ECDIS are configured to
authenticate against this Public Key. The UKHO will migrate to the IHO public key in the future when it
is considered safe to do so without causing any inconvenience to existing users.
Check the Public Key
Before installing AVCS ENCs, the user must check that the correct Public Key is installed on the
system. The method of managing and viewing these will vary between different makes or versions of
ECDIS. If the PRIMAR Public Key is not present on the system then it will have to be installed before
AVCS ENCs can be loaded. See the Error! Reference source not found. section below for the
method of managing the Public Key on this particular ECDIS.
ECDIS Authentication Warning
New build ECDIS, type-approved against the latest IMO ECDIS Performance Standards (Jan 2009),
will report a warning when installing AVCS. The message reads as follows:
SSE26 - This ENC is not authenticated by the IHO acting as the Scheme Administrator
Users should acknowledge these, if prompted to do so, but should not be alarmed as the source and
integrity of the ENCs are authenticated correctly against the PRIMAR Public Key. Other errors or
warnings relating to the validity of the public key or certificate should be reported, see the section on
Getting Help.
Emergencies
In certain circumstances it may be necessary for a vessel to get access to an AVCS ENC at very
short notice, for instance, if having to divert from the planned route in a medical emergency. See
Emergency ENC Permit Generation in the Getting Help section.
Before installing AVCS ENCs the system must be set to the correct mode of operation. In the case of
AVCS this is “S57”. There are three steps to this procedure which the following screenshot illustrates.
1 Make sure the “Menu” option is visible in the bottom right hand side of the viewer.
2 Right click the mouse or tracker ball assembly to display the “Chart Menu” drop down menu.
3 In the “Activate S57 chart” drop down menu select either “Ignore Scale” or “Sync Scale” (at this
stage it does not really matter).
Menu: → right click mouse [Chart Menu] → Activate S57 chart → Ignore Scale or Sync Scale
Version 1.0
• Ignore Scale: Display S57 ENC at the same scale used previously to open an S57 ENC.
• Sync Scale: Display S57 ENC at the same scale as the current ARCS chart in the viewer.
The Pre-installation Checks section identifies some pre-installation checks that the user should carry
out before loading AVCS ENCs into the system. These checks are primarily aimed at systems which
had ENCs from another service installed prior to converting to AVCS. It is also prudent to carry out
the following checks when installing AVCS on newly delivered systems.
Data Cleansing
The Data Cleansing section highlights the need for new AVCS customers, who had previously
subscribed to other ENC services, to remove (purge) all ENC Permits and ENCs from the system
before installing AVCS. It also outlines the reasoning behind this recommendation, the following
section outlines the method of carrying this out on this ECDIS.
Furthermore the ECDIS will not install ENCs from AVCS unless the correct Public Key is installed. If
the correct Public Key is not installed the ECDIS will report an Authentication Failure.
When the “Chart Operations” window is displayed the user can
choose to remove (delete) some or all of the installed ENCs from the
system database (SENC). The example across has the GB directory
highlighted, clicking the “Remove Chart” button will remove all GB
ENCs from the SENC. Users can choose from a number of remove
options as follows:
1 Remove one or more countries ENCs in a single action.
2 A subset of a countries ENCs by usage band (navigational
purpose)
3 One or more of a particular country’s ENCs, e.g. a single ENC
The following screenshots seek to illustrate the combinations listed above.
When the “Remove Chart” button is clicked the user will be asked to confirm the operation. Cl ick “OK”
to continue removing the ENCs. As the ENCs are removed from the database a “Progress Dialog” is
displayed.
Version 1.0
Check the Public Key
Before installing AVCS ENCs, the user must
check that the correct Public Key is installed
on the system. If the PRIMAR Public Key is
not present on the system then it will have to
be installed before AVCS ENCs can be
loaded.
ECDIS Authentication Warning
New build ECDIS, type-approved against the
latest IMO ECDIS Performance Standards
(Jan 2009), will report a warning when
installing AVCS. The message reads as
follows:
SSE26 - This ENC is not authenticated by
the IHO acting as the Scheme
Administrator
Users should acknowledge these, if prompted
to do so, but should not be alarmed as the
source and integrity of the ENCs are
authenticated correctly against the PRIMAR Public Key. Other errors or warnings relating
to the validity of the public key or certificate
should be reported.
The “Public Key” window displays the currently installed public key. The Admiralty Vector Chart
Service currently uses the PRIMAR.PUB, issued by Primar Stavanger, to authenticate its AVCS
ENCs.
The PRIMAR.PUB file
The following public key is used to authenticate ENCs distributed through the Admiralty Vector Chart
Service. The contents of the “Public Key” window should be checked to see if the correct one is
installed.
A copy of the public key file should have been supplied with this guide. If not the user can copy the
text reproduced below under the heading AVCS Public Key (PRIMAR.PUB). When copying start at
“//Big p” and finish at the full stop at “C4BF.” Open Notepad and paste the contents into it. Save the
resultant text file as “PRIMAR.PUB”. This can then be installed in the ECDIS as described below.
Install the PRIMAR.PUB file by clicking the “Load New” in the “Public Key” window. A “Public Key
Load” window will be displayed where the user can browse to the source of the PRIMAR.PUB file,
highlight it and click “Load”.
A new “Public Key” window will shown displaying the “PRIMAR.PUB” public key file. This will not
overwrite the currently installed public key until the user clicks on “Accept New”.
NOTE: Information relating to the SSE26 warning, as shown in the screenshot above, is provided in
the paragraph headed ECDIS Authentication Warning.
Remove Installed ENC Permits
If the user has previously subscribed to another ENC service it is advised to remove these from the
system. The following section on Managing ENC Permits describes how this can be done.
When removing ENC permits from the system the user has two options as follows:
1. Automatic: Remove all permits clicking on the “select all” option and clicking “remove”. The
“Unselect all” button reverses this “Select all” operation.
2. Manual: The removal of ENC permits by selecting an individual ENC permit or a selection of
ENC permits.
AVCS ENCs are currently distributed on CD-ROM and DVD media and are encrypted according to
the International Hydrographic Organization (IHO) S-63 Data Protection Scheme. Initially the AVCS
user is provided with ALL of the latest base and update discs which contain all the ENCs in AVCS.
However these cannot be accessed by the ECDIS unless a valid set of S-63 ENC Permits is installed.
Each ENC Permit is unique and is the method which gives the user selective access to particular
ENCs required for an intended voyage(s). To obtain a set ENC permits the user must provide the
Admiralty Chart Agent with a User Permit. The User Permit is 28 character alphanumeric string which
should have been supplied with the paperwork that accompanied the ECDIS on delivery. The User
Permit can also be viewed from within the system see the section on Viewing the ECDIS User Permit.
The AVCS Licence
The AVCS ENC Permits will be supplied to you by your Admiralty Chart Agent in a zipped file. The
contents of this file will depend on the user’s bridge configuration as each AVCS licence allows for
use on up to 5 ECDIS. When extracted, one or more set of permit files (PERMIT.TXT and ENC.PMT)
will be copied automatically into folder(s) named MASTER, BACKUP, RESERVE1, RESERVE2 and
RESERVE3 depending on the number of ECDIS configured on the bridge. The contents should be
extracted to a media, e.g. USB flash drive or floppy disk that can be read by the system.
The “Load File” button is used to initiate the ENC permit installation to the ECDIS. When selected a
“Permit load” window will be displayed. In this window the user will have to identify the source folder
or external drive where the ENC permits are stored. When the source has been selected the user
must highlight the “PERMIT.TXT” file then click “Load” to install the AVCS ENC permits.
When removing ENC permits from the system the user has two options as follows:
1. Automatic: Remove all permits clicking on the “select all” option and clicking “remove”. The
“Unselect all” button reverses this “Select all” operation.
2. Manual: The removal of ENC permits by selecting an individual ENC permit or a selection of
ENC permits.
The “Backup” button is used to make a backup copy of the
installed permits in case they are accidently removed from the
system.
Select “Backup” and a window will be displayed which allows the
user to browse to either an internal or external drive. Users are
advised to keep a note of where the permit files were saved.
Selecting the “Enter Man.” option allows the user to manually enter an ENC permit. In cases of
emergency this function may be required. Especially if it is not possible to send new permit files to a
vessel because they do not have e-mail capability or the mail server is down. The ENC permit string
can be provided over the phone or using other methods, e.g. NAVTEX, etc.
When selected the user is presented with a “Text Input” dialog box with an option to “Enter Permit”.
Right click in the text field and the user will be presented with option to select an “On screen
keyboard”. Selecting this option will display a keyboard as shown in the screenshot below.
Alternatively, and if available, the user can input the string from a conventional keyboard.
After the ENC permit string has been correctly typed in the text field click “OK” to install the ENC
permit.
Viewing the ECDIS User Permit
Menu: → right click mouse [Chart Menu] → System → User Permit → “S57 Message” dialog
The User Permit is a 28 character alphanumeric string that is unique to each ECDIS installation or
group of ECDIS, e.g. multiple bridge installations. The User Permit should have been supplied at the
time of delivery and must be used when ordering an AVCS licence and ENC permits.
If the User Permit is mislaid it can be retrieved from within the system. Bring up the “Chart Menu” and
select “System” and then “User Permit” as shown below. The Use r Permit is displayed in an “S57 Message” box.
AVCS data is delivered on a series of CD-ROMs2 (or a single DVD) labelled Base and a CD-ROM
labelled Update. Each Base disc contains all the ENC base cell files and associated updates for
those producer nations identified on the CD label. Users are provided with all ENCs in the service but
can only access those ENCs that they are licensed for. The AVCS Base discs are periodically reissued to free up space on the AVCS Update CD, this is currently about every 6 to 8 weeks. The
AVCS Base discs must be loaded first before any AVCS Update CD can be loaded.
The AVCS Base disc label contains the date and week of issue. Users should be careful to only load
an AVCS Update CD that is newer than the installed bases. Users with internet access can check the
status of the latest AVCS Base CDs using the following link:
http://www.ukho.gov.uk/AVCS
Click on the Licensing and Updating tag to view the AVCS distribution and issue dates.
NOTE: Although ECDIS equipment and ENCs are designed to be very reliable, there is a slightly
increased risk of problems occurring when ENCs are being added, removed or updated. For this
reason, you must not attempt to make changes to the installed AVCS ENCs when the equipment is
being used for primary navigation or if the vessel is committed to an imminent departure.
Version 1.0
Installing AVCS for the first time
It is recommended that users carry out the “Pre-installation Checks” before proceeding to install ENCs
from the AVCS Base discs.
New AVCS customers will be provided with an AVCS licence (permit files) and a complete set of
AVCS Base CDs by the Admiralty Chart Agent. The AVCS permit file must be installed first before
any AVCS ENCs can be loaded. A Schedule A should also have been supplied with the permits files.
This document informs the user which Base discs are required to install all the user’s licensed ENCs
in the Home CD column.
There are currently 9 AVCS Base CDs but this number will grow as more ENCs become available for
distribution within AVCS. It is unlikely that users will need to install all of the CDs in order to load all
licensed ENCs. Reference to the Schedule A can avoid the unnecessary loading of some CDs and
save the user time. A small sample of the information contained in the Schedule A is provided below.
RFA03 – English Channel Holding Expiry Date 31.12.2010
Cell Title Home CD AVCS Update
GB301820 Isles of Scilly and Western Approaches AVCS Base 3 N/A

GB202872 Selat Karimata and Approaches AVCS Update N/A
Note: If the user does NOT have a copy of the Schedule A then the complete set of AVCS Base CDs
must be installed to ensure that all licensed ENCs are imported to the system.
2
All the latest AVCS Base CDs are available for download from the UKHO website. This can be found using the
following link http://www.ukho.gov.uk/ProductsandServices/ElectronicCharts/Pages/AUS.aspx
the instructions in the Digital Products Downloads box. These are contained in a series of zipped files named
AVCS_WKWW_YY_BaseN, where WW is the week number, YY the year and N is number of the base.
Menu: → right click mouse [Chart Menu] → Load and Update Charts → from CDR OM
With the first AVCS Base CD installed in the CD-ROM drive select the “Load and Update Charts”
option from the “Chart Menu” then select “from CDROM” from the “Load and Update Charts” menu.
NOTE: If there is no CD-ROM in the drive the software will prompt the user to browse to an
alternative source.
The following “Load or Update Charts from loaded CDROM” window will be displayed. A high level
description of the contents of this window is provided below:
The “Load or Update Charts from loaded CDROM” window identifies the source, wee k num ber, date
of the installed CD-ROM as well as base CD identifier. In the above example this is “RENC_BASE GB WK39 2010 9 30 3_9” and converts as follows:
“RENC” Official data issued by a RENC
“BASE” Flags either a BASE or UPDT
“GB” Service Provider is GB
“W39” Week of issue is week 39
“2010 9 30” This is the date the CD was issued, i.e. 30
th
September 2010
“3_9” AVCS Base CD 3 installed from a set of 9 CDs
Choosing the Load Selectors
In the Load Selector section, you can select what ENCs to install:
Option Description
Name:
The ECDIS will display the ENC Cell Name inside the ENC limits on the
graphical presentation.
Permit:
ECDIS will highlight the ENCs which are available on the CD-ROM
which have installed permits.
RENC Cancelled Charts:
ECDIS will display ENCs in the list which are cancelled by the RENC
and contained on the CD-ROM.
Group:
If the user has a predefined group of charts, e.g. voyage plan, the
ECDIS will highlight those ENCs in that group which are available on the
CD ROM.
Missing only:
Loads and displays on graphical presentation only ENCs and updates
which are not already loaded into the ECDIS
Manual Selection:
Navigation purpose
The user can highlight desired ENCs from a list
All 6 usage bands (Navigational purposes) are listed, users can filter out
those usage bands not required for a particular leg of a voyage. It is
prudent to have ALL
the usage bands checked as above.
NOTE: It is not recommended to install cancelled ENCs even if permits are available. Cancelled
Charts (ENCs) are not updated and can quickly become out of date and as such unsafe
for Navigation. If however “Cancelled” ENCs are installed a “Permanent Message” will be
The filtering options provided above are aimed at users with a good understanding of ENC standards.
Filtering can reduce the installation times but should NOT
be used if the user is unsure of the
consequences.
Important User Information
In the “Load or Update Charts from loaded CDROM” window at the bottom are several buttons that
can be used to access important information, manage groups, etc. It also contains the button that
starts the AVCS ENC Installation process.
Menu: → Chart Menu → Load and Update Charts → from CDROM → Load
Clicking the “Load” button initiates the AVCS ENC Installation and
Conversion.
AVCS ENC Installation and Conversion
After selecting the “Load” option the system will display the following
“Load from CD” window (across). This informs the user that “Loading may take time and prevent route monitoring. Click OK to continue. The
load times will depend on the number of ENCs licensed in the permit
file.
Occasionally the following “S57 Message” window will be displayed
informing the user that “RENC Product List not loaded”. This normally
occurs when ENCs are reloaded from AVCS base CDs after a later
Update CD has been applied. Each CD-ROM in the AVCS service
contains a file (PRODUCT.TXT) in the INFO folder. It is continually
updated each week to inform the ECDIS of the precise status of the
Admiralty Vector Chart Service. The ECDIS always stores the latest
version of this file. Installing new ENCs from the base CDs can invoke
this message.
After all windows have been acknowledge by clicking “OK” a progress
dialog will be displayed.
A “Progress Dialog” will be displayed but before it begins to cycle through the validation and copy
process a SSE26 message is displayed in a “Load or Update Charts” window. This is to be expected
and the window should be acknowledged by clicking “OK”. See the paragraph on ECDIS Authentication Warning for further information on this message. It will only be displayed once at the
beginning of each Load or Update process.
The system will now copy the encrypted AVCS ENCs to the hard drive prior to conversion from S-57
to the system database format (SENC).
When the system has cycled through all the licensed ENCs a
“SENC CONVERSION in progress” window will be displayed.
This window shows all licensed ENCs and the corresponding
updates, as each one is converted it is removed from the list.
At the end of the process the list will be empty.
The following CD History” window will be displayed informing the user of the source of the ENCs and
details about the Load and Conversion dates and times.
Users can now view the Load and Conversion log file by clicking on the “Load and Conv. History”
button. A Notepad window labelled “TEXT VIEW” will be displayed listing all converted ENCs.
Additional information is listed against each ENC which includes the date and time of processing, the
edition and update number of each ENC and the latest issue date, plus whether the conversion was
successful or not. An example is provided below.
AVCS is updated on a weekly basis and updates are distributed on CD-ROM3. The only exception to
this is in a week when the AVCS Base discs are re-issued; in these instances an AVCS Update CD
will not be issued. The AVCS Update CD contains all new ENCs, new editions of ENCs and ENC
updates issued since the last set of AVCS Base discs were issued. The CD is cumulative so the user
only has to load the latest week number. Users can update their system using the AVCS Update CD
or remotely over the Internet using the Admiralty Updating Service (AUS).
The Weekly Update CD
Your Admiralty Chart Agent will provide you with a weekly Update CD, when it is practical to do so.
The AVCS Base discs are re-issued about every 6 to 8 weeks depending on the amount of data on
the Update CD. It is important that users do not attempt to load an Update CD that is not consistent
with the Base discs. For example, you should not attempt to load an update that is older than the
Base discs held on board. When new AVCS Base discs are issued the user must install these before
attempting to load the latest Update CD.
Version 1.0
Periodically the user will be supplied with an updated set of AVCS ENC Permits. New permits must
be issued for any ENC that has had more than one new edition.
NOTE: On older ECDIS equipment the AVCS permit file is specific to a particular week as described
in the Schedule A. It is important that users do not install these unless they have the
corresponding Update CD for the same week. Failure to follow this advice could render some
of the installed ENC unavailable for use in the ECDIS. The only exception to this rule is if
additional coverage is required in case of emergency or a change to a planned route. Furuno
systems which have been type approved after January 2009 are not affected by this
issue.
Re-Issue of the AVCS Base CDs
In the weeks when the AVCS ENC Base CDs are re-issued it is important that the user installs all the
relevant base CDs (see Installing AVCS for the first time). This is because the base CDs will contain
New Editions or Updates necessary to keep the users system database (SENC) up to date. Failure to
apply the new AVCS base CDs will result in errors when installing a later AVCS Update CD.
The Admiralty Updating Service
The Admiralty Utilities Installation CD which comes with the AVCS Start-Up Pack contains a copy of
the Admiralty Updating Service application. This application, when installed, provides the user with
the capability to download updates directly, over the Internet or by e-mail, from a server hosted in the
UKHO. For more details see the EOUS (ENC Online Update Service) Customer Service Guide on the
Utilities CD.
NOTE: Although ECDIS equipment and ENCs are designed to be very reliable, there is a slightly
increased risk of problems occurring when ENCs are being added, removed or updated. Fo r
this reason, you must not attempt to make changes to the installed AVCS ENCs when the
equipment is being used for primary navigation or if the vessel is committed to an imminent
departure.

The latest AVCS Update CD is available for download from the UKHO website. This can be found using the
following link http://www.ukho.gov.uk/ProductsandServices/ElectronicCharts/Pages/AUS.aspx
instructions in the Digital Products Downloads box. It is in a zipped file named AVCS_WKWW_YY_UPD T, where
WW is the week number and YY the year.
After all the relevant AVCS Base discs have been installed, the ECDIS can now be updated. The
update process is very similar to installing the bases. Insert the latest AVCS Update CD in the drive.
Menu: → Chart Menu → Load and Update Charts → from CDROM → Load
In the “Chart Menu” select “Load and Update Charts”, then select “fr o m CDROM” from the “Load and
Update Charts” menu. This will display a “Load or Update Charts from loaded CDROM” window.
This should, if the correct CD is installed, identify the source as
being an update as follows:
Confirm that the correct Load selectors” have been chosen and
click “Load”.
The system will display similar progress indicator, warning
message and conversion progress windows as for when
loading AVCS base CDs. When the conversion process has
finished the following CD History” window will be displayed
informing the user of the source of the ENCs and details about
the Load and Conversion dates and times.
Users can now view the Load and Conversion log file by clicking on the “Load and Conv. History”
button.
A Notepad window labelled “TEXT VIEW” will be displayed listing all converted ENCs. Additional
information is listed against each ENC which includes the date and time of processing, the edition and
update number of each ENC and the latest issue date, plus whether the conversion was successful or
not. An example is provided below.
See the section on “Reviewing the Installation Log” for more details about the various warnings that
may be displayed in this log.
Users may see the following SSE 27 warning message when in either route planning or route
monitoring mode.
This message is displayed when viewing an ENC that not as up-to-date in respect of the latest
PRODUCTS.TXT file loaded or maintained on the system. A permanent warning message must be
displayed on screen informing the user, e.g. “ENC<cell name> is not up to date. A New Edition, Re-issue or Update for this cell is missing and therefore MUST NOT be used for Primary NAVIGATION”.
User should carry out the instructions given in the “Permanent Message” dialog above and check the
“Load Conversion History” to see if there were any problems when the ENCs were installed. If there
were any critical warnings then these should be reported.
Automated Update Warning Message
The Furuno ECDIS periodically checks the date of the last installed
product listing received from the RENC/Service Provider or when
the latest base or update CD was applied.
If the installed product listing is more than 30 days old the system
displays a “S57 Message” box stating the following:
“RENC Product List is more than 30 days old. User charts may not
be up-to-date. Load Update disk issued within 30 days”.
The SENC Conversion log can be viewed by clicking on the Load and Conv. History button in either
the “Load or Update Charts from loaded CDROM” or “CD History” windows. Alternatively it can be
accessed at any time using the following:
Menu: → right click mouse [Chart Menu] → System → Log File → “Text View” window
It provides information relating to the import and conversion of ENCs to SENC and reports
appropriate messaging. The following section identifies (in italics) the various messages whic h may
be reported when importing ENCs to the ECDIS. These are accompanied by a brief explanation of the
consequences in respect of the SENC.
Conversion Messages
1. Correct conversion without errors from an Official Source
ENC converted without errors and can be used for primary navigation
2. Correct conversion without errors from a Non Official Source (i.e. non ENC)
“Successful auto conv: ENC: T1500400.000, edt: 1, upd: 0 / 2009 5 9 NON ENC”
A private S-57 vector chart cannot fulfil SOLAS requirements and users must refer to the paper chart
as the primary aid to navigation when navigating in the area covered by this ENC.
3. ENC conversion with errors, but the ENC is partly usable
Successful auto conv with errors: ENC GB100001.000, edt: 3, upd: 4 / 2010 10 12
Use cell status to check details of errors. Note that the chart is still an ENC.
4. Conversion errors, but the ENC is partly usable as NON ENC
Successful auto conv with errors: ENC: GB402300.000, edt: 1, upd: 0 / 2010 1 4 NON ENC
Use cell status to check details of errors. Note that the chart is no longer an ENC if it was produced by
a Hydrographic Office. Users must refer to the paper chart as the primary aid to navigation when
navigating in the area covered by this ENC.
ENC is not usable and the user cannot view or use it. You must refer to the paper chart as the primary
aid to navigation when navigating in the area covered by this ENC.
6. Failed conversion of an update
Failed auto conv: ENC: GB500005.001, edt: 2, upd: 1 / 2007 9 26 Updating impossible before new
edition of Base cell
ENC is partly usable, but it is not up-to-date and users will need to obtain the latest edition from the
ENC producer. Note that the chart is still ENC, but no longer fulfils SOLAS requirements. Users must
ENC is not usable and users cannot view it. Try to reload the Base ENC or Update from the original
media. If this does not work order a new CD-ROM from your Chart Agent. Users must refer to the
paper chart as the primary aid to navigation when navigating in the area covered by this ENC.
8. Failed conversion. Checksum of an update is not correct (update may be corrupted)
ENC is partly usable, but it is not up-to-date. Try to reload the update from the original media. And if
that doesn't work order a new CD-ROM from your Chart Agent. Note that the installed ENC no longer
fulfils SOLAS requirements. Users must refer to the paper chart as the primary aid to navigation when
navigating in the area covered by this ENC.
9. Failed conversion. At least one of the previous updates has failed in its SENC conversion
The system cannot accept additional updates unless all previous updates have been successfully
applied and converted into the SENC. ENC is partly usable but it is not up-to-date. Try to reload the
failed update from the original media (in this example the failed update is GB520005.002). And if that
does not work, order a new CD-ROM from your Chart Agent. Note that the installed ENC no longer
fulfils SOLAS requirements. You must refer to the paper chart as the primary aid to navigation when
navigating in the area covered by this ENC.
10. Failed conversion. The Base cell has failed in its SENC conversion
Failed automatic conversion: ENC: GB432900.001, edt: 1, upd: 1 / 2007 9 8 PREVIOUS Base CELL
OR Update MISSING
The system cannot accept updates unless the Base cell has been successfully converted into the
SENC. ENC is not usable and you cannot view it. Try to reload the ENC Base Cell from the original
media (in this example the failed Base cell is GB432900.000). And if that does not work order a new
CD-ROM from your Chart Agent. You must refer to the paper chart as the primary aid to navigation
when navigating in the area covered by this ENC.
NOTE: Always study both the “Failed SENC conversion” dialog and “Conversion history log” very
carefully, because they may contain important information about the legal status of a
particular ENC. An ENC may lose its legal equivalency to the paper chart as far as SOLAS
requirements are concerned. In these instances users will need to refer to the paper chart as
the primary aid to navigation.
Permanent warnings are provided to bring to the attention of the user the status of the installed ENCs
and highlight those that may not be up-to-date on the ECDIS. In cases where ENCS are not up to
date warnings are displayed permanently in the viewer to make the user aware that some
correctional/remedial action is required to the ECDIS database (SENC). Only up-to-date S57 ENCs
can be used as legal replacements for the paper chart. Permanent warnings will appear if the system
detects a condition that may result in the use of the ENCs which are not up-to-date.
NOTE: The system can assist in keeping ENCs received from an official RENC or Service Provider
up-to-date; see the section on “System Maintenance”. For S-57 vector charts which have
been loaded from sources other than a RENC, the system is unable to know the exact up-todate status.
ECDIS Permanent Messages
For further details see the section on
“System Maintenance”.
Version 1.0
For further details, see the section on
“System Maintenance” and “Viewing
ENC/AVCS Coverage”. ENC Limits
coloured orange in the catalogue are not
up-to-date in the ECDIS.
The user has loaded an update which
contained a cancellation message for an
ENC. The user has selected not to remove
the cancelled chart and this permanent
indication reminds users about the intended
use of a cancelled ENC. Users should
consider removing the ENC from the SENC.
For information on how to remove S57
ENCs, see the section on “Removing Installed ENCs”.
Chart permit has been removed after ENC
was loaded and converted to the SENC.
The user has expired permit(s) for the chart
in “Chart Permit” dialog. Remove permit or
renew subscription for permit <cell name>.
To remove the permit(s) see the section on
Viewing status and setting viewing dates of S57 ENCs
Menu: → Chart Menu → Set Chart viewing dates → “Chart viewing dates” window
When S57 ENCs are loaded and updated, the system sets “Display Until” of S57 ENCs as the current
date of the system. To set “Approve Until” as current date of the system, you must open the “Set Chart viewing dates” dialog box and perform “Approve Until”.
Version 1.0
The recommended settings in the “Chart viewing date” window are
as follows:
• Sync Manual Update Dates: checked (ticked)
• All SENCs: checked (ticked)
The “Chart Viewing Dates” window
RENC edt/upd: The column “RENC” contains edition/update status from Product List (This is always read from the latest PRODUCTS.TXT file included on either the AVCS base or update CD).
SENC edt/upd: The column “SENC” contains the edition/update status of the system database
(SENC), i.e. status of ENCs loaded and converted in the ECDIS.
Updates displ. until (Date until updates are displayed): The user can enter the required date by
using the “Display Until” field. The number after the date shows the number of updates for th e
displayed cell (number of displayed updates/number of updates in SENC format).
Updates approv. until (Dates Updates are approved to): The user can enter the required date by
using the Approve Until field (number of approved updates/number of updates in SENC format).
Latest RENC Product List: This identifies the source of the RENC or RENC accredited service
provider as well as the date it was issued. The RENC Product List contains information about all
ENCs available in the ENC service If the ECDIS does not contain any Product List, then the date of
the Product List is displayed as not valid using the abbreviation “—NVLD—”.
Status of a ENCs from RENC/Service Providers
To keep ENCs up-to-date, you should check for updates from the RENC/Service Provider weekly.
The ECDIS compares ENCs listed in the RENC/Service Provider Product Listing. If a Permanent
Warning appears on the ECDIS viewer this is a result of a difference in the status of the currently
installed ENCs and the Product Listing. It is usually an indication that one or more of the installed
ENCs is not up-to-date. See the section on “Permanent Warnings”.
The information of available ENC and their up-to-date status is available both in the ECDIS “Chart Catalogue” and in the “Chart viewing dates” window.
NOTE: The easiest method to check if ENCs are up-to-date is to view the colour coded catalogue and
check that the names of all required charts appear in green. The names of charts which are not up-todate appear in orange. For further details see “Viewing ENC/AVCS Coverage”.
To view the Product List in a graphical presentation, use the catalogue, which can be displayed by
opening the “Chart Menu” and choosing the “Chart Catalogue” option. The catalogue of S57 ENCs
shows the status when the user last received a product listing from the RENC and/or Service Provider
or when loading the latest Base or Update CD ROM into the ECDIS.
The “Chart Catalogue” window allows the user to select the “Viewing Filters” so that only the relevant
coverage and ENC status can be examined. The filter option allows users to select to view ENCs from
the catalogue of the following:
Note: The ECDIS automatically keeps the latest available
Product List. Thus the ECDIS does not load the Product List
if it is older than the one already loaded into the ECDIS.
If a newer one is already stored on the system the S57 Message” dialog will be displayed.
This will occur if the user reverts to the base CDs to install
new or additional ENCs after updating the ECDIS with a
newer update CD.
The Catalogue Colour Coding
The Furuno system uses a system of colour coding to highlight the status of each ENC. The display
will very much depend on the filtering applied and the users installed ENC permits.
Green: The ENC is available for use in SENC format. If the source of the ENC is a RENC, then the
ENC is also up-to-date. If the source of the S-57 vector chart is something other than a RENC then all
loaded updates are included into the SENC.
Orange: The ENC is available for use in SENC format but it is either not up-to-date or has been
cancelled. This could be for several reasons, either the SENC is from a previous edition, the latest
SENC update was missed or the ENC has been cancelled.
Red: If an ENC is installed in the SENC but does not have a corresponding permit installed then the
ENC is no longer available for display in the viewer.
Blue: The chart is available either in ENC format, in SENC format for another software version or in
SENC format for another ECDIS. For example the ENC is blue during SENC conversion and if you
loaded a ENC into the ECDIS and the system could not convert the ENC into SENC format.
Magenta: You have a permit to use the ENC, but the ENC is not available in SENC format and thus
you cannot use the ENC currently.
This particular example below shows the complete content of an installed CD-ROM with no filtering
applied. The ENC limits shown in green identify ENCs that have valid permits installed and which can
be imported into the ECDIS.
NOTE: The “CD” option is selected with ALL
None of the “View Filters” are checked.

Technical Support
Who should you contact?
You will receive the most effective support if you address your initial query to the correct organisation. This
will usually be the manufacturer of the ECDIS equipment, or the Admiralty Chart Agent you obtain your
AVCS ENCs from, but in certain circumstances you may need to contact UKHO Customer Services.
Problem Contact
Hardware problems: difficulties with the keyboard, mouse, display or main
system console, failure of a floppy disk or CD drive.
Software problems: difficulties with configuring or using the ECDIS system
software, interfacing problems.
ENC installation problems: problems with installing certificates, permits and
AVCS ENCs, standard error codes displayed (see AVCS User Guide).
ENC content problems: display anomalies or mismatched data displays.

Contact details are available on the last page of this guide.
When reporting a ENC-related problem, it is useful if you can provide the following details:
The AVCS license number
The ECDIS system (and model/version) being used (especially if you have more than one system on
board)
The date and week number of the latest base and update discs held on the vessel
The issue date of the latest ENC Permits held. If the problem appears to be related to the permits it is
best to send a copy of the latest ENC Permits held by email if this is possible.
Any error messages displayed on the ECDIS (see page 18 of the AVCS User Guide)
Emergency ENC Permit Generation
In certain circumstances it may be necessary for a vessel to get access to an AVCS ENC at very short
notice, for instance if she has to divert her route due to a medical or safety emergency. In these
emergency circumstances only, individual AVCS ENC Permits can be obtained from the UKHO 24 hours a
day, 365 days a year. These permits can be transmitted direct to the vessel by email wherever possible, by
fax, or simply by reading the characters out over the telephone or radio. Each permit consists of 64
characters.
Contact details for the UKHO are available on the last page of this guide. Please quote your vessel name,
the User Permit Number of your ECDIS system and the required ENCs.
We hope this User Guide assists you in using AVCS with this system. If you have any feedback on the
content of this particular guide, or the online FAQs, please forward your comments to your Admiralty Chart
Agent or directly to the UKHO.
