Synthetic Message:
A 21 message is issued marking an AtoN station that is not equipped with an AIS Transponder,
but there is a buoy or beacon tower in the programmed position.
Virtual Message:
A 21 message is issued from an AtoN station that does not physically exist in the programmed
position. This creates a virtual AtoN in a place where a real AtoN does not exist. It can be used
to mark new hazards.
5.3.4. SETTING UP THE STATUS ENTRIES.
The AtoN Msg 21 status message contains binary-encoded information such as a bit stream.
The status bits contain information about the operation of the beacon, Racon, and the AIS AtoN
transceiver itself.
Status information can be obtained from 3 different sources:
- ACE statements through RS422 port.
- Digital inputs of the ATON transceiver module
- Digital inputs of the sensor module.
The following screen describes the Digital Setup and Input screen.
Current status (msg 21)
This section shows the current state of light and Racon. The MTUAIS must be powered for the
sensor plate to work.
Beacon and Racon Configuration:
This section allows you to adjust the parameters of the beacon and Racon. Selectors must be
selected depending on the installation in which MTU AIS is installed. For example, if the beacon
status output is connected to the MTUAIS, it must be selected, if a Racon is installed, it may or
may not be monitored and must be selected correctly.
