BIIT Failure Actions
This section allows configuration of the text message to be transmitted on detection of a Built In
Integrity Test failure (BIIT failure). Such a failure may indicate a problem with the transceiver and it may
be prudent to warn vessels not to rely on the information provided by the transceiver in this situation.
Note that the health of the transceiver is always transmitted as part of the standard Aids to Navigation
position report (message #21), however the status contained in that message may not be shown on all
display systems. The available actions on BIIT failure are:
• No action - no message is transmitted on detection of a BIIT failure
• Transmit message #14. A broadcast text message is transmitted on detection of a BIIT failure. The
text content of the message must be defined in the ‘Message text’ box.
• Transmit message #12. An addressed text message is transmitted on detection of a BIIT failure.
The destination for the addressed message is configured on the ‘Real AtoN’ tab.
In addition to configuration of the BIIT failure action, a schedule for the associated message must be
configured in the ‘Message schedule’ tab:
• Message #14 Index 1 must be configured if the message #14 action is selected.
• Message #12 Index 1 must be configured if the message #12 action is selected.
The layout of the alert messages configuration tab is illustrated in the following picture:
