OVERVIEW
The T300B is a compact and rugged SOTDMA AIS Transponder
designed for the demands of the commercial boat, fishing boat and
leisure markets. It meets the Class B (SOTDMA) standard, allowing
vessels that are not required to fit Class A units to voluntarily fit an AIS Transponder.
When connected to an external VHF antenna and a GPS antenna (not
supplied), the T300B will transmit its own vessel position and data and
also receive information from other AIS vessels, shore stations and
navigational aids within VHF range.
The unit is initially programmed by the user with the supplied
software over a USB interface. The T300B is compatible with a range
of computer based navigation programs and chart plotters, that
can accept AIS data sentences over a NMEA 0183 or NMEA 2000 connection.
