If the alternative out-of-position message is activated, the MTUAIS will send the alternate MSG
21 that will be configured in the "message program" with a faster sending sequence to alert the
navigators that the buoy is adrift.
The out-of-position threshold determines the maximum displacement of a buoy relative to the
programmed target position.
• MMSI for addressed messages.
This is the MMSI identifier used for addressed messages that are generated by the MTU-AIS.
Typically, it is the MMSI of the base station that will receive status information.
Dimensions
The dimensions of the AtoN must be introduced approximately 1 meter as recommended by the
IALA A-126.
• Radio channels.
It is possible to configure the radio channels for the transmission of messages in most cases the
AIS1 and AIS2 channels are used.
Radio transmitter power
The power level emitted by the MTU-AIS can be adjusted 1W, 2W, 5W or 12.5W. The standard
12.5W option in most situations except, which, for some reason, you want to limit the
transmission range:
5.3.2.
