areas as defined by the master or by the policy of the ship's owner. They are always
available regardless of the type of chart material used.
• Circle: The operator can define an area with a circle, which can define a location to
avoid. If route or estimated ship position is going to cross the area, the system gen-
erates a warning to the user. These areas can be used to specify safe areas as de-
fined by the master or by the policy of the ship's owner. They are always available
regardless of the type of chart material used.
• Label: There are two types of labels: point and label. A "point" (i) is mainly used to
denote position of objects, such as buoys, light houses, fixed targets, wrecks, etc.
Points can be used in chart alert calculation. A "label" provides user-entered text to
show on the display.
13.2 How User Charts are Synced
User chart data can be shared between this ECDIS and other like units (FMD-3x00,
FCR-2xx9 or FAR-3xx0), through the LAN. Turn on all units beforehand to enable
syncing. The unit first powered becomes the master unit (sync source), and the user
chart data are automatically synced by the sync source. The unit selected as the sync
source depends on the number of units connected, as shown in the table below. If the
power of the initial sync source is turned off, the 2nd unit turned on becomes the sync
source.
Be aware that if a unit is turned off, some user chart data may be deleted. The steps
below illustrate this using ECD001 and ECD002.
1) ECD002 is off; ECD001 is powered and a user chart is created at ECD001.(Sync
source: ECD001)
2) The power to ECD001 is turned off. ECD002 was turned off at step 1, therefore the
user chart is not delivered to ECD002.
3) ECD002 and ECD001 are powered in that order. (Sync source: ECD002)Because
the sync source became ECD002, the user chart created at step 1 is deleted.
Number of units
Sync source
ECDIS
(FMD-3x00)
Chart Radar
(FCR-2xx9, FAR-3xx0)
One unit One unit The unit (ECDIS or chart radar) first
powered be-comes the sync source
and syncs user chart data.
Two or more units More than one unit The ECDIS unit (No. 1 ECDIS or No. 2
ECDIS) first powered syncs user chart
data (a chart radar can-not be the sync
source). However, if a “Planning EC-
DIS” is used, the Planning ECDIS
syncs the route data. (Planning ECDIS
usage/no usage is set at installation.)
