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 a coding error in an ENC, the Failed SENC
conversion window appears with a list of failed ENCs. In this window you can select any of the charts to see the
reason for failure in conversion.
Normally the conversion is initiated automatically when a chart is loaded. Section 8.3 "How to Load S57 Charts"
describes the loading process. Section 8.4.2 describes how to select automatic conversion. You can also initiate
conversion from The SENC Convert window or from a cell status window.

How to speed up SENC conversion

The SENC conversion speed depends on how many other tasks the system is occupied with. The system can conduct
SENC conversion in the background during any other system operations, but you can greatly lessen the time for
SENC conversion by doing the following:
1. Disable radar overlay by choosing radar overlay mode as "ECDIS only".
a) Place the cursor on Mode selection in the status bar.
b) Select "ECDIS only" and then push the scrollwheel.
2. Select display mode (upper left corner on the status bar) as True Motion.
3. Spin the scrollwheel to display Set Chart Center/Info/Active Scroll in the mouse functions area then push the left
mouse button. Set chart center so ship is off the screen or TM reset is OFF.
4. Set the scale to 1:1,000 by displaying Range+/ /Range- in the mouse functions area and pushing the appropriate
mouse button to display 1:1,000.

button.
