7.3 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 chart radar. The chart radar 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 choose any of the charts to see the
reason for failure in conversion.
Normally the conversion is initiated automatically when a chart is loaded. Section 7.2 Loading S57 Charts describes
the loading process. Section 7.3.2 Choosing automatic SENC conversion and display until date describes how to
choose automatic conversion. You can also initiate conversion from The SENC Convert window or from a cell
status window.
7.3.1 Speeding up SENC conversion
The SENC conversion speed depends about 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 the radar.
a) Spin the scrollwheel to display Chart Display/Info/Standard Display in the guidance area then push the left
button.
b) Click the right arrow tab to display the Standard page.
c) Uncheck
Radar.
d) Click the X at the top right corner of the window to close the window.
2. Choose 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 guidance area then push the left 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 guidance area then pushing the appropriate button
to display 1:1,000.
