Digital Yacht ZDIGAIT2500 Class B+ SOTDMA AIS Transponder with GPS

The Digital Yacht AIT2500 is a professional-grade Class B+ SOTDMA AIS transponder that delivers superior performance for marine navigation and vessel tracking. This advanced transponder utilizes SOTDMA (Self-Organized Time Division Multiple Access) technology, offering significant advantages over standard Class B transponders including 5W transmission power—2.5 times more powerful than regular 2W Class B units—and guaranteed time slots for transmission even in congested traffic areas.

Key Features:

• Class B+ SOTDMA technology with 5W transmission power for extended range and reliability
• Guaranteed transmission time slot in high-traffic density areas
• Variable transmission rates that increase with vessel speed for real-time tracking
• GPS/GLONASS dual positioning capability for accurate location data
• Multiple connectivity options: NMEA 0183, NMEA 2000, and USB interfaces
• Dual NMEA 0183 inputs supporting both 4800 and 38400 baud rates with multiplexing capability
• Receives AIS targets up to 30 nautical miles range
• Compatible with all AIS-enabled chart plotters and navigation software
• Optional AIS SART alarm capability for man overboard (MOB) device integration
• Remote silence switch capability for disabling transmit function when needed
• Free ProAIS2 configuration software for PC and Mac

The AIT2500 is supplied complete with an external GPS antenna and requires connection to a VHF antenna or VHF-AIS antenna splitter. Fully backward compatible with existing Class B and Class A AIS systems, this transponder is ideal for ocean sailors, fast powerboats, and smaller commercial vessels requiring the best possible AIS performance and future-proof satellite tracking capabilities.
