T200B AIS Class B CSTDMA Transponder

SKU: COM-0001

The T200B is a compact and rugged AIS Transponder designed for the demands of small commercial boats, fishing boats and leisure markets.

It meets the Class B standard, allowing vessels not required to fit Class A units to voluntarily install an AIS Transponder. 

When connected to an external VHF antenna and a GPS antenna (not supplied), the T200B will transmit its vessel position and data and receive information from other AIS vessels, shore stations and navigational aids within the VHF range.

The user initially programs the unit with the supplied software over a USB interface. The T200B is compatible with various computer-based navigation programs and chart plotters that accept AIS data sentences over a NMEA 0183 or NMEA 2000 connection.
