The AIS-3R is a high performance, dual channel AIS receiver, with outputs for both NMEA 0183 and USB. The AIS-3R reads and decodes all AIS messages that are specifieded and transmitted by AIS Class A and Class B transponders, AIS SARTs and Aids to Navigation. The AIS targets together with all the static and dynamic information received can be displayed on any AIS compatible Chart Plotter or PC navigation program such as seaPro.

The unit can be operated in various modes to suit the particular application. If connected by a USB cable to a PC the unit is powered by the PC and data is transmitted via the USB cable providing a compact solution Whilst powered by the USB, NMEA 0183 output is also available from the Power/Data port.

If required a NMEA 0183 GPS input can be connected via the Power / Data port, the GPS sentences will be multiplexed with the AIS data to provide position information to the PC.
Note: Connecting the GPS directly to the PC or other device is recommend.

The unit can be powered directly from an external 12/24V DC power supply (ships batteries) and can provide both USB and NMEA 0183 data output
