In normal conditions, the unit transmits a report with AIS AtoN position in an ITU-R M.1371
message 21. In addition, the AIS AtoN broadcasts AIS Message 6, which enables the operator to
monitor the AtoN device for solar/battery voltage, flash setting and light status. Subject to the fitting
of appropriate measuring devices, meteorological/hydrological data and other parameters can be
obtained via Message 8. A brief summary of all the messages processed by the AIS AtoN are
defined in section 1.4.
MANDO-301/303 AIS AtoN are fully IALA and IEC compliant devices, and provide users choices
from basic PCB modules to rugged aluminum enclosed unit. The compact PCB module (102mm x
105mm x 49mm) is giving a great flexibility for users to integrate AIS AtoN transceiver into their
floating lantern or buoy. The weatherproof anodized aluminum housing (140mm x 155mm x 60mm)
offers user the variety of mounting methods.
Moreover, AMEC’s MANDO series is one of the most power-saving AtoN transceivers with the low
power consumption while offshore power resources are limited.
MANDO-303 is also equipped with multiple digital/analog interfaces, which provides user the
flexibility to connect other communication devices, hydraulic, and metrological sensors.
