Comar T200B Class B AIS Transponder

The T200B is a compact and rugged AIS Transponder, designed for the demands of the small commercial boat, fishing boat and leisure markets. It meets the Class B standard that allows 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 T200B will transmit its own vessel position and data and 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 T200B 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.

Note: This product was previously known as the CSB200
