1.6 Receiving AIS Messages
The AIS unit can receive safety related messages from other ships. These messages are transmitted to
the system and stored in the MFD until up to a maximum number of 50 for a certain time period.
If the maximum number of messages is reached, the oldest messages will be deleted automatically.
New messages generate a warning in the alarm system in order to alert the operator of viewing the
message text in the target related message list.
New Safety Message
When the AIS electronics unit receives a safety message, this is sent to the connected interface and the
New AIS Safety Message warning appears in the alarm list of the MFD. By acknowledgement the
warning disappears from the list.
The operator must open the safety message list via Tools > Target > Message in order to have access
to all received and temporarily stored messages.
Fig. F / 1 AIS Message List after receiving a new safety message
The list is sorted according to the receive time of the messages; the latest (newest) entry is shown
at the top of the list. The sorting sequence of the list cannot be changed.
Any message from the same source with the same text as already received will not be stored again,
but its time marking in the list will be updated. In this way it will show up in the first line again.
The receive time, the identification data of the transmitting AIS object and the start of the text are
shown above the message. The complete text is enclosed in the frame below the list of messages.
By a click into a line of the list you can select the message to be shown in the text window.
In the first column of the list a yellow alarm icon is shown if the related message alarm is not yet
acknowledged. Additionally all new (unread) messages have a marker in the second column until
the message has been selected and shown in the text window.
