10.3 Proprietary configuration sentences
The following section documents the proprietary NMEA0183/IEC61162 sentences used for AIS AtoN
configuration and control. These sentence relate mainly to configuration of data capture and integration with
external equipment.
10.3.1 Status Bit Source
The MCR SBS command is used to set the source for the AtoN status bits which are transmitted in AIS AtoN
position reports (message #21). Refer to sections 6.1.1 and 6.1.3 for further information on the available
interfaces for status information.
10.3.2 Status Bit Source Query
This command issued to query the transceiver for the current Status Bit Source configuration. The response
will be in the format described in 10.3.1.
10.3.3 Lamp / RACON configuration
The MCR LRC command is used to configure the fixed status of a connected Lamp and / or RACON. This
affects the setting of the related status bits transmitted in message #21.
Note 7 The third data field provides the sequential message identifier. The sequential message identifier provides a
message identification number from 0 to 9 that is sequentially assigned and is incremented for each new
multi-sentence message. The count resets to 0 after 9 is used. For a VER reply requiring multiple sentences, each
sentence of the message contains the same sequential message identification number. It is used to identify the
sentences containing portions of the same VER reply. This allows for the possibility that other sentences might be
interleaved with the VER reply that, taken collectively, contain a single VER reply. This data field may be a null field
for VER replies that fit into one sentence.
Note 1 Status bit source is either:
0 = ACE sentence provides status bits
1 = Transceiver basic IO connections provide status bits
2 = Extended sensor interface provides status bits (applies only to variants including the extended
Note 2 This field is used to indicate a sentence that is a status report of current settings or a configuration command
changing settings. This field should not be null.
“R’ = sentence is a query response,
“C” = sentence is a configuration command to change settings.
Note 1 This field is used to indicate a sentence that is a status report of current settings or a configuration command
changing settings. This field should not be null.
“R’ = sentence is a query response,
“C” = sentence is a configuration command to change settings.
Note 1 Set the lamp fitted status, 1 = lamp fitted, 0 = lamp not fitted
Note 2 Set the RACON fitted status, 1 = RACON fitted, 0 = RACON not fitted
Note 3 Set the RACON monitored status, 1 = RACON monitored, 0 = RACON not monitored
