Add Class B AIS traffic awareness and vessel-position transmission to a compatible chartplotter with the SI-TEX MDA-1 Metadata AIS Transceiver. Its internal 50-channel GPS receiver, NMEA 2000/NMEA 0183/USB connections, and Wi-Fi support give boat owners flexible options for sharing AIS data with navigation displays and mobile devices. Need a compact AIS transceiver that can fit a protected interior installation? The MDA-1 operates from 12V or 24V DC and requires programming with valid vessel MMSI and static data before it can transmit.
Integration
The MDA-1 needs a dedicated AIS/VHF antenna or approved splitter, a compatible MFD, chartplotter, computer, or mobile app, and accurately entered MMSI/static vessel data. It is not a radar, VHF voice radio, chartplotter, EPIRB, or guaranteed collision-avoidance device.
AIS data relies on VHF reception and on other AIS-equipped vessels transmitting correct information. Receiving AIS targets does not mean every boat, buoy, floating object, or hazard will appear. Before transmitting in the U.S., obtain and program the correct MMSI and follow applicable radio rules. [926][928]
Before Ordering
Confirm MFD or chartplotter compatibility, MMSI availability, required AIS/VHF antenna or splitter, GPS antenna placement, desired NMEA/USB/Wi-Fi interface, 12V/24V power source, and protected mounting space before ordering.
