Used as an aid to collision avoidance, the CA2 combines the trusted technology and fluid product design that have become synonymous with ACR products.

The AIS message-sending functionality is simple to use, ensuring safety-related messages can be quickly delivered or received by the user with very little effort. An instant message and alarm function provide immediate notification of any potential problems or hazards including the deployment of ACR’s AISLink Man Overboard Beacon. It is also compatible with all other automatic identification systems and AIS maritime Man Overboard devices including Ocean Signal’s MOB1, the world’s smallest Man Overboard AIS/DSC device.

Dynamic data such as location, speed over ground, and course over ground is calculated automatically using the integrated 99-channel GPS receiver, while the static and voyage related data such as MMSI, call sign and name, type of ship, destination, ETA, etc. is easily programmed into the AIS equipment via a user-friendly menu interface.

This single unit solution to meet AIS requirements ensures minimal use of bridge space and its surface or free-standing mounting options allow for easy installation into almost any position or location. It also includes multiple connectivity options including WiFi, USB port, serial, and Pilot plug.
