This Class-B AIS transceiver module enables both the transmission and reception of AIS data from your boat. Your vessel identification data is programmed into the TR-210 using the software and cable included with the transceiver.  The TR-210 AIS transceiver output connects to your GPS/Plotter via the NMEA 0183 interface and to your PC through the USB connector. The TR-210 has an internal GPS antenna providing vessel position data to the AIS transmitter. 
An external GPS antenna can be connected if necessary (ref. 62173).
