The AIT2500 is a top - notch Class B+ 5W SOTDMA AIS transponder with GPS. Digital Yacht's Class B+ AIS transponders use SOTDMA format transmissions. With a 5W power output (2.5 times more powerful than regular Class B), it ensures a guaranteed transmission time slot in busy areas and faster update rates based on the vessel's speed. Ideal for ocean sailors, fast power boats, and smaller non - mandated commercial vessels, it works well with existing Class B and Class A systems. This full - function transponder has NMEA 0183, NMEA 2000, and USB data outputs. It comes with a GPS antenna and needs to be connected to a VHF antenna or a suitable VHF - AIS antenna splitter. There's also an option for an AIS SART alarm, great for personal AIS MOB devices. Specifications: Class B+ 5W transponder with GPS/GLONASS positioning; multiple NMEA 0183 in/out and multiplex capability; NMEA 2000 connectivity; USB connectivity for PC/MAC; remote TX silence switch option; supplied with GPS antenna; options include VHF - AIS antenna splitter, wireless interface (WLN10SM), and AIS SART Alarm (AIS Lifeguard). Note on SOTDMA Technology: Class B+ uses SOTDMA messaging instead of CSTDMA. It guarantees a transmission time slot even in high - traffic areas, has a 5W transmission power (compared to 2W for Class B), and a speed - based transmission rate. Regular Class B has a fixed 30 - second transmission rate when the vessel is moving. It's perfect for those who need top - notch performance and future - proof satellite tracking.

Using the AIT2500 is quite straightforward. First, make sure you have it programmed by a qualified technician as required by the FCC. You'll need to fill out a form and provide the necessary documents. Once it's programmed, connect the supplied GPS antenna and connect it to a VHF antenna or a VHF - AIS antenna splitter. The transponder has multiple data outputs like NMEA 0183, NMEA 2000, and USB, so you can connect it to other devices easily. If you choose to use the AIS SART alarm, it can work great with your personal AIS MOB devices. When it comes to maintenance, keep it dry and clean. Check the connections regularly to make sure they're secure. If you're not using it for a long time, store it in a cool and dry place. Remember, in high - traffic areas, the SOTDMA technology ensures your AIS transmission gets a time slot, so you can have peace of mind while on the water.
