Garmin Cortex-M1 AIS Class B SOTDMA smartAIS

The Garmin Cortex-M1 AIS Class B SOTDMA SmartAIS Transponder is a high-speed safety hub for serious sailors. It combines AIS, GPS, and heading data with smart safety logic and seamless NMEA networking to your chartplotters and MFDs.

• AIS: SOTDMA Class B AIS with two dedicated receive channels and 5 W transmit power for reliable vessel visibility on AIS networks.
• Dedicated AIS receive channels: Two dedicated AIS receive channels to ensure robust vessel tracking on busy networks.
• AIS power output: 5 W output for clear AIS transmissions.
• DSC Class: Class D DSC with one dedicated receive DSC channel.
• Dedicated DSC channels: 1 dedicated RX DSC channel.
• NMEA networking & data sharing: NMEA 2000 gateway with AIS, GPS & MOB PGN output and translations to/from NMEA 0183; data can be shared across existing NMEA networks.
• NMEA 2000 gateway: Isolated micro-C male port for reliable network integration; supports gateway translations to/from NMEA 0183.
• NMEA 0183 detail: Isolated NMEA 0183 port for AIS & GPS sentences; 4800/38400 baud; translations to/from NMEA 2000.
• Wireless security: WPA2 Personal protection for wireless connectivity.
• Region: U.S., Canada, International.
• Anchor drag & environment monitoring: Uses actual bow anchor position and built-in heading sensor to trigger alarms when drag or hazardous conditions are detected.
• Man overboard (MOB) detection: MOB alerting with quick track-back modes when used with AIS MOB beacon to help locate a person in the water.
• Proactive collision alerts: Directional voice announcements (e.g., “collision alert, starboard bow”) to help you respond quickly.
• VHF-ready integration: Add a Cortex handset for full VHF radio capability (sold separately) to expand communication options on deck.
• VHF voice: Dedicated RX VHF channels: 3; VHF power output: 25 W, 1 W (high, low).
• Rugged marine hardware: Compact 168 x 168 x 58.7 mm enclosure (770 g) with IPX8 water rating; operates on 9–33 V DC and draws up to 6 A at 12 V (700 mA nom).
• Power & electrical: Operating voltage 9–33 V; current draw 12 V: 6 A max, 700 mA nom.
• Peripherals & sensor expansion: GPIO port and supplied cable for monitoring bilge pumps, security sensors, shore power, and more; supports up to five external sensors for expanded monitoring.
• Splitter & connectors: SO239 antenna connector; SPLITTER: max input power 25 W; RX loss 0 dB, TX < 2 dB; SPLITTER connector: BNC.
• Unit size: 168 x 168 x 58.7 mm (6 5/8" x 6 5/8" x 2 5/16").
• Weight: 770 g (1.7 lbs).
