After loading all charts desired, the chart
conversion (from ENC to SENC) automatically
starts.
8. At this time, the message [No Base Cell
available] and chart cell numbers are displayed
in the [S57 LOAD] window. Then, place the
cursor on the [OK] button and press the
[SELECT] key.
The chart CD-ROM which is issued by the
Hydrographic Department, Maritime Safety
Agency of Japan contains all chart data, but
there are some areas which the base charts cell
(last three digits of chart number : 000) are not
installed in the ECDIS. These chart cell numbers
are displayed.
9. If the message [Update number is too low] and
chart cell numbers are displayed in the [S57
LOAD] window, place the cursor on the [OK]
button and press the [SELECT] key
This message means that the ECDIS does not
update older version charts contained in the
CD-ROM.
For example, if the lower three digits of the chart
numbers are 001 to 028, 001 - 015 are not
updated (not used) and 016 - 028 are updated.
The chart cell numbers to be updated are displayed
in the [Conversion list] on the [SENC CONVERT]
window. The chart is updated cell by cell from the
top of the list. After the conversion has been
completed, the chart numbers disappear from the
window. Further the color of a chart cell frame
changes to green when conversion of the cell is
completed. The conversion may take 4 - 5 hours,
depending on the quantity of chart numbers
installed.
