3.2 Using Ethernet interface
Using this port, the RA-2500 is connected to the Ethernet port on a PC or a network node.
See chapter 7.3 for description of LAN connector.
3.3 Not all ships carry AIS
It is important to remember that not all ships carry AIS, in particular leisure crafts, fishing boats,
warships and some costal shore stations including Vessel Traffic Service Centers.
3.4 Use of AIS in collision avoidance
As an anti-collision aid the AIS has some advantages over radar:
- Information provided in near real-time.
- Capable of instant presentation of target course alternations.
- Not subject to target swap.
- Not subject to target loss in clutter.
- Not subject to target loss due to fast maneuvers.
- Able to detect ships within VHF/FM coverage.
-
IMPORTANT
When using the AIS for anti-collision purposes it is important to remember that the AIS is an
additional source of navigation information. It does not replace other navigational systems. The AIS
may not separately always give the right picture of the traffic in your area.
3.5 Erroneous
information
Erroneous information implies a risk to other ships as well as your own. Poorly configured or
calibrated sensors might lead to transmission of incorrect information. It is the users responsibility
to ensure that all information entered into the system is correct and up to date.
