AIT2500 Class B+ 5W SOTDMA AIS with GPS

Digital Yacht have a range of Class B+ AIS transponders. Class B+, a standard, utilizes SOTDMA format transmissions which offer a 5W power output (2.5x more powerful than a regular Class B), a guaranteed time slot for transmission in busy traffic areas and faster update rates depending upon the speed of the vessel. It’s ideal for ocean sailors requiring the best possible performance and future proof satellite tracking applications, fast power boats and smaller non-mandated commercial vessels. It still inter-operates with existing Class B and Class A systems.

The AIT2500 is a full function SOTDMA AIS transponder with NMEA 0183, NMEA 2000 and USB data outputs. It is supplied with a GPS antenna and requires connection to a VHF antenna or suitable VHF-AIS antenna splitter.

The AIT2500 has the option of an AIS SART alarm which is great for use with 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+ is a generation of AIS functionality based on SOTDMA (self organised TMDA) messaging rather than the simpler CSTDMA (carrier sense TDMA).  It guarantees your AIS transmission will get a time slot, even in areas of very high traffic density.  It also specifies a 5W transmission power (compared with 2W for Class B) and a transmission rate that increases as the vessel moves faster.  With regular Class B protocol, the transmission rate is fixed at every 30 seconds when the vessel is moving. It is ideal for ocean sailors requiring the best possible performance and future proof satellite tracking applications, fast power boats and smaller non-mandated commercial vessels.

FAQs

Please read our FAQs page to find out more.

When will my order ship?

For in-stock items, orders placed by 4:00 PM EST are eligible to ship the same day. If any item in the order is not currently in stock, shipment timing will depend on availability.

What is your return window?

Eligible merchandise may be returned within 30 days from the date of receipt. All returns require a Return Merchandise Authorization (RMA) number before anything is sent back. For the smoothest experience, we ask customers to contact Salina Vita first so we can coordinate the request properly. Returned merchandise must be complete, in its original packaging, and in resalable condition. Items that arrive incomplete, improperly packed, or not suitable for resale may not qualify for return approval.

Are restocking fees possible?

Yes. Approved returns may be subject to a restocking fee of up to 15%. Non-stock items may not be returned. In addition, opened or unsealed DVDs, CDs, and cartography products are non-returnable unless defective. If the product falls into CWR’s excluded media categories—such as opened or unsealed cartography, DVDs, or CDs—it is not returnable unless defective.

If my unit needs warranty service, should I send it back to Salina Vita?

No. Units requiring service, whether under warranty or otherwise, should be returned directly to the appropriate manufacturer, not to Salina Vita. We are always happy to help guide you to the correct manufacturer support path. Absolutely. While the service destination is the manufacturer, we can help you identify the proper support channel and make the process feel more straightforward and well-managed. Units that require service themselves, however, should go directly to the manufacturer under CWR’s policy.

I still have more Questions, can we contact you?

At Salina Vita, we believe premium marine commerce should feel measured, transparent, and reassuring. If you have a question about a shipment, return eligibility, or manufacturer service, contact us before taking the next step and we will guide you with the discretion and clarity your vessel deserves.
