Calling an AIS vessel
If the system includes a VHF radio supporting DSC (Digital Select
Calling) calls over NMEA 2000, you can initiate a DSC call to other
vessels from the IS42.
From the Call dialog you can change channel or cancel the call. The
Call dialog is closed when the connection is established.
AIS SART
When an AIS SART (Search and Rescue beacon) is activated, it starts
transmitting its position and identification data. This data is received
by your AIS device.
If your AIS receiver is not compliant with AIS SART, it interprets the
received AIS SART data as a signal from a standard AIS transmitter.
An icon is positioned on the AIS page, but this icon is an AIS vessel
icon. If your AIS receiver is compliant with AIS SART, the following
takes place when AIS SART data is received:
• An AIS SART icon is located on the page in the position received
from the AIS SART
• An alarm message is displayed if you have enabled the siren, the
alarm message is followed by an audible alarm.
Ú
Note: The icon is green if the received AIS SART data is a test
and not an active message.
Vessel alarms
You can define several alarms to alert you if a target shows up
within predefined range limits, or if a previously identified target is
lost.
