Using technology from Class A AIS, the CB2 has a faster reporting rate with reserved time slots for transmissions to ensure your broadcast does not get blocked in high traffic areas.  The AISLink CB2 will transmit every 5 seconds while older Class B AIS units can only transmit once every 30 seconds.  The CB2 also transmits at 5 watts of power, versus older Class B AIS that only transmit at 2 watts, broadcasting to a larger area for improved visibility. 

Utilizing 99 acquisition channels and 33 tracking channels, the internal multi-GPS receiver continuously transmits your vessel information including position, speed, course, and heading, ensuring an indication of the most accurate global positioning at all times. In addition to transmission of dynamic vessel information, the AISLink CB2 also continuously transmits static information including vessel name, call sign, vessel type, vessel dimensions, and MMSI number. 

Programming static information into the AISLink CB2 proves effortless as the user has the ability to simply upload this information via Wi-Fi using ACR’s free mobile app. For increased flexibility for the maximum number of users, the app is conveniently available from either the App Store (Apple) or the Google Play Store (Android). 

Upon completion of the quick and easy installation process, the AISLink CB2 receives and interprets messages from other AIS-equipped vessels within range and then seamlessly communicates this information to other navigation devices on your vessel such as chart plotters, laptops, or mobiles using the CB2’s NMEA 0183, NMEA 2000, USB or WiFi outputs.

A primary benefit that users can rely on is the transmission priority provided by the AISLink CB2 due to the use of the SOTDMA access scheme versus CSTDMA. The use of SOTDMA guarantees the same AIS transmission priority as a class A transponder, ensures a faster reporting rate with transmissions every 5 seconds instead of every 30 seconds, and also ensures a higher output power of 5 Watts instead of 2 Watts. These features not only allow the CB2 to convey a more “real-time” picture of your vessel’s position but also enables your transmissions to reach further.

Additional benefits include a multi-color LED indicator light communicating the ongoing operational status of the unit. Given that the CB2 also comes complete with an external GPS antenna, users have the ability to be transmitting AIS messages and enjoying the many benefits of the AISLink CB2 within minutes of install.   

The AISLink CB2 provides a significant advantage in navigational safety, giving you the peace of mind that your vessel will be seen day or night on even the busiest waterways, regardless of what the weather may be.
