TEST AIS-SART
It is required to enter the USER ID number of
the AIS-SART before starting tests. This allows
ignoring the messages from other AIS stations.
It will help to perform tests by means of antenna
through broadcast in port area.
You may directly input MMSI using numeric
buttons, or select the position by buttons

The 000000000 MMSI code means the filter is
not applied, so the device will receive all
messages from any AIS station.
Note that not only zero value can be displayed here. The tester automatically offers
to use the MMSI encoded from last received message. So, if the MMSI number of
AIS-SART is unknown or you’d like to avoid the manual input of the code use
AIS
MONITOR
mode and receive at least 1 message from the AIS-SART. Then return
