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 choose any of the charts to see the
reason for failure in conversion.
Normally the conversion is initiated automatically when a chart is loaded. Paragraph 8.3 "Loading S57
Charts" describes the loading process. Paragraph 8.4.2 describes how to choose automatic conversion. You can also
initiate conversion from The SENC Convert window or from a cell status window.
Note: SENC conversion must be done in the single-workstation mode. Switch to single-workstation mode before
converting, following the procedure below. This procedure should also be followed when converting C-MAP Ed.2
charts to SENC format.
1. Multi-workstation mode to single-workstation mode conversion
(1) Operating procedure at workstation designated as sensor source
- Right-click "MULTI" at the bottom of the information area to show the Initial Settings dialog box.

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 radar overlay by choosing radar overlay mode as "ECDIS only".
a) Click Radar on the status bar with the left mouse button to show the Radar Overlay window.
b) Choose "ECDIS only" and then push the thumbwheel.
2. Choose control of visible navigation features as "Off" for radar overlay.
a) Roll the thumbwheel to display Chart Display/Info/Standard Display in the mouse functions area and then
push the left mouse 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.
3. Choose display mode (upper left corner on the status bar) as True Motion.
4. Spin the thumbwheel to display Set Chart Center/Info/Active Scroll in the mouse functions area and then push
the left mouse button. Set chart center so ship is off the screen or TM reset is OFF.
5. 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.
