em-trak B922 Class B AIS Transceiver w/WiFi & Bluetooth Wireless Connectivity – 2W CSTDMA
Transmitting 2W CSTDMA vessel coordinates directly to navigation networks, this em-trak B922 marine transceiver combines an internal GPS/GLONASS engine with built-in Wi-Fi and Bluetooth, drawing 1.7W average inside an IP67 waterproof enclosure at 0.88 lbs.
- Built-in Wi-Fi and Bluetooth stream navigation data
- Internal GPS/GLONASS receiver locks positional fixes
- Draws 1.7W average to preserve boat power
- IP67 waterproof rating protects against water ingress
- NMEA 2000 bus links marine chartplotters
Add receive-only AIS targets to an NMEA 2000 network with the Digital Yacht AISnode. Its dual-channel receiver listens to both AIS channels and places received target information directly on a compatible Micro-C backbone, making it a compact option for chartplotters that support NMEA 2000 AIS data. Need AIS awareness without transmitting your own vessel position? The AISnode draws power from the NMEA 2000 bus, uses low current, and fits into a protected onboard installation.
Integration
The AISnode needs a compatible NMEA 2000 display and an AIS/VHF antenna or approved splitter. It is not an AIS transceiver, VHF voice radio, GPS receiver, chartplotter, radar, or emergency beacon. Since it is receive-only, it cannot make your boat visible to other AIS users.
AIS reception depends on antenna height, antenna quality, cable condition, local radio interference, terrain, weather, and other vessels broadcasting valid AIS data. AIS does not show every boat or hazard and should be used alongside radar, charts, a proper lookout, and safe navigation practices.
Before Ordering
Confirm NMEA 2000/Micro-C compatibility, available backbone capacity, AIS antenna or splitter needs, receiver mounting location, chartplotter AIS support, and whether receive-only operation meets the vessel’s needs before ordering.
