PRODUCT DESCRIPTION
*A link to download firmware update software and the corresponding instructions on doing the firmware update are included at the end of this section
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.
As a leader in life-saving marine products for both professional and recreational use, ACR provides unparalleled safety and peace of mind with the AISLink CB2 AIS Transceiver.

What information is transmitted?
Position reports (MMSI, Lat, Long, COG, SOG) for Class B (SOTDMA)
- Every 3mins. when SOG < 2 knots
- Every 30s when SOG >= 2 knots < 14 knots
- Every 15s when SOG >= 14 knots < 23 knots
- Every 5s when SOG > 23 knots
Vessel data (Name, call sign, dimensions, type, etc.)
This means that if you are moored or in the marina your data may take some time to be visible on other people’s systems. Depending on your location visibility on Marine Traffic or Shipfinder websites may take much longer.
Can I use an existing GPS receiver or GPS data instead of installing an additional GPS antenna for the AIS?
No. The use of the internal GPS receiver is a requirement of the AIS regulations. The AIS can be used as a position source output by configuring it to output GPS position data (RMC NMEA sentence) although this is not generally recommended.
Can I change the MMSI or vessel details?
Always take great care when entering the MMSI number. Once programmed changing the MMSI number will require the AIS to be ‘unlocked’ by contacting ACR Electronics via the set-up app. This could take up to 2 days. Changing all other details entered is simple using the Mobile or Web-based set-up apps. Download the ACR AIS App on the App Store or Google Play.
How do I connect my CB2 AIS to my existing navigation electronics?
The CB2 comes with both NMEA0183 and NMEA2000 communication protocols.
To connect using NMEA0183 you will require some suitable connector block and the wiring information for your other manufacturer’s equipment.
To connect using NMEA2000 you will require a spur (drop) cable suitable to connect to the DeviceNet (male) connector on the AIS to an existing NMEA2000 backbone. An unused connection on the backbone must be available.
What type of radio antenna should I use?
The CB2 AIS transmits and receives on the VHF band so any good quality Broad Band Marine Grade VHF antenna will be suitable.
There are antennas specifically tuned for AIS which are available and are suitable but other narrowband antennas or antennas specifically tuned for VHF radio should be avoided. If a single antenna is to be used by VHF radio and the CB2 then an active antenna splitter should be installed.
What is the range of AIS?
This varies enormously depending on weather, VHF antenna height, etc.
- The typical transmit range for Class B is 10nm
- The typical receive range for Class A targets is 20nm
- Receive range can exceed 100nm in the right conditions
How do I configure my CB2 AIS?
The CB2 AIS needs to be configured by the user to enter the vessel’s MMSI number and other vessel details.
This can be carried out by a mobile app or a web-based program:
- For the Mobile Android version search the Playstore for ACR AIS Config
- For the Mobile iOS, version search the App Store for ACR AIS Config
- For the Web, version click here: CB2 New Configuration Program
