The T200B-S is a compact and rugged AIS Transponder with built-in
Antenna Splitter, 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-S will transmit its
own vessel position and data and receive information from other AIS
vessels, shore stations and navigational aids within VHF range.
The built-in Antenna Splitter allows the unit to share a single VHF
antenna with a VHF radiotelephone, eliminating the need for a second
VHF antenna on the vessel and reducing installation time and cost.
Additionally, the unit has an FM radio output for monitoring public
service FM radio broadcasts.
The unit is initially programmed by the user with the supplied software
over a USB interface. The T200B-S is compatible with a range of
computer based navigation programs and chart plotters that accept
AIS data sentences over a NMEA 0183 or NMEA 2000 connection.

• Small commercial boat, fishing boat and leisure markets.
• Meets the Class ‘B’ international standard that allows vessels
that are not required to fit Class ‘A’ transponders to voluntarily (or
otherwise) fit an AIS transponde

• With built-in Antenna Splitter to simplify installation
