How-to Convert ENC charts to Qastor 3 format

To be able to use ENC charts in Qastor 3 they need to be converted to the Qastor 3 format.

This can be done by using the ENC Administrator program.

ENC Administrator is a Windows only program.

ENC Administrator can be downloaded from the QPS website at: https://qps.nl/downloads/qastor/

(If Qastor 2.5 is installed, ENC Administrator is already available and doesn`t need to be installed again.)

Once installed, the program can be found at: C:\Program Files (x86)\Common Files\QPS\ENC Administrator by default.

ENC Administrator

The ENC Administrator program converts various types of electronic charts to the QPS format, which is *.QNC.

 Start ENC Administrator:

  1. Directly from the program folder C:\Program Files (x86)\Common Files\QPS\ENC Administrator\EncAdministrator.exe
  2. Windows key and type ENC Administrator in the search box
  3. Make a Desktop shortcut or pin to the Windows taskbar

The following dialog will appear:

Chart data folder

Chart data folder
ENC target folder

Set the correct ENC target folder using the browse button [...] on the right.
From this folder the ENC charts will be loaded into Qastor/Qinsy.

When no other importing or generating of permit files is necessary, just setting this folder will be sufficient, followed by pressing the Finish button.

Reset folder

The factory default storage location for the charts is: \Users\Public\Documents\QPS\Shared\Charts.
When the charts are stored here, the button wil be grayed out.

When a different folder was set as the storage location, then the button is activated.

Not used by Qastor 3.

This user permit is a finger print from the hard drive or the HASP dongle.

Chart import

S-57 & Inland ECDIS
  • Select "S-57 & Inland ECDIS" from the Chart Import section, after that select "Next" to continue.

The following dialog will appear:

ENC Data Folder

  • Select the correct folder where the *.000 files are located, this can also be on a removable media or from a network drive.
  • Select "Next" to continue.
  • Select "Start Import Process" to start the conversion of *.000 files to *.QNC.
    ENCAdministrator will automatically store the converted charts in the previous selected target directory.
  • When the conversion is finished select "OK" to exit this dialog.

S-63 Protected charts

Primar and UKHO are examples of suppliers of S-63 protected charts.

Take the following steps in order to decrypt S-63 protected charts.


User permits

For S-63 Protected charts a user permit must be generated in order to decrypt the charts and to view them in Qastor 3.
The user permit will be used in a later stage of the decryption process.

S-63 user permit

In short it works as follows:

  • Create a User Permit file named User Permit.txt
  • Send this to the ENC chart vendor
  • They will supply a password file named Permit.txt
  • The combination of the User Permit and Permit file allows the charts to be converted and used


  • Select "Generate a S-63 user permit", select "Next" to continue.

The following dialog will appear:

  • Select ‘Dongle Device or Harddisk’ from the pull down menu.
    In case of a corporate license the option "Shared Primar key on dongle device" can be selected.
    This option must be enabled on the HASP dongle or softlock license.
  • Enter the company name (Optional)
  • Select "Next" to continue.


The ENC Administrator has now generated a User Permit file.

  • Select "Save" to save the user permit on your computer.
    The user permit file will be used later during the decrypting process.

This User Permit file must be sent to the chart distributor. The ENC distributor will then send you the Permit.txt files.

  • Select "E-mail" and the e-mail address can be entered.
  • Select "OK" to finalize and send the e-mail.
  • Select "Finish" to complete.


Decrypting

After receiving the permit files from the distributor, the decrypting of S-63 protected charts can be started.

  • Select "S-63 Protected Charts" from the Chart Import section.
  • Select "Next" to continue

The following dialog will appear:

ENC Data Folder

Specify the ENC source folderSelect the location of the S-63 protected charts.
Review the updates during the processUpdating of the process can be shown if needed by ticking the box.
Encryption (S-63)
Location of the permit fileSelect the location of the password files provided by the distributor.
See paragraph User permits down this page.
Location of the user permitSelect the filename of the User Permit. This user permit file was created earlier on the same computer.
See paragraph User permits down this page.
Browsing is also possible by pressing the [...] button on the right-hand side.
  • Select "Next" to continue.
  • Select "Start Import Process" to start the decrypting process (this may take a few minutes).

When the conversion is finished select "OK" to exit this dialog. 

S-63 protected charts are now installed on the computer and can be displayed by Qastor 3.

When a ENC update is received repeat the steps described under "Decrypting".
The permit files received from ENC vendor and the “User Permit” are still valid.


If S-63 encrypted charts are used:

In Qastor 3 go to Settings > Main Menu > Chart Preferences > S63  User permit.

Copy/Paste the 28 character User permit to Qastor.



In Qastor 3 Windows version the QNC charts folder as set in the ENC Administrator will be used.

On an IOS device (iPad/iPhone) the QNC charts can be transferred to the device using iTunes or the Apple File app.

How-to Upload charts from Windows to iPad using iTunes and How-to Upload charts to IOS devices using the Apple Files app describe how to do this.
