All fields are provided with further information; please refer to ITU-R M.823-2 / RTCM SC 104

3.4.6 Alarm Circuit – BIIT Channel 10
The AIS requires that an alarm output (relay) must be connected to an audible alarm device
or the ships alarm system, if available.
Alternatively, the BIIT (built-in integrity test) alarm system may use the alarm messages
output on the presentation port (ECDIS Port Channel 5), provided the ECDIS alarm system is
connected and AIS compatible.

The additional “Extended NMEA

of how to use the proprietary NAUTICAST sentences.
