12.1.4 Integrating an ARPA Radar
NOTE
When integrating a radar which will accept data from ECDIS, it must
not share a COM port with any other navigation device.
ECDIS’s ARPA radar interface allows you to integrate up to 6 radars as well as
display and track up to 20 acquired targets with optional target tracks, target
trails and heading vectors. The targets appear on the display as green colored
symbols.
The target trails are like a high resolution ship’s track. They
contain only a limited
number of points. Once a trail is ”full,” ECDIS begins dropping points off one end
of the trail while adding them to the other. Target trails are displayed in real time
only
⎯ that is, they cannot be saved and redisplay. To turn them off, simply se-
lect the Off button in the ARPA Radar Tracking dialog box.
ARPA target heading vectors are the same length as your own ship vector.
ECDIS is capable of sending marker, lines and route information to selected ra-
dars. When sending information to be displayed on this radar, it must be the ra-
dar selected to be used in the ARPA Radar Tracking dialog box.
If ECDIS does not receive a signal from the target, the target is cleared from the
display. Please see ”Selecting the Navigation Devices”, chapter 7.1.2.
By default, targets are labeled numerically. You may, however, define a user as-
signed label of up to ten characters.
