The R220U is a high performance dual channel AIS receiver with outputs for both NMEA 0183 and USB. The R220U reads and decodes all AIS messages that are specified 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.

The unit can be operated in various modes to suit your application. If connected solely 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 data port. NMEA 0183 Input from a GPS can also be connected via the data port which is multiplexed with the AIS data to provide position information to the PC.

Connecting the unit to external 12/24VDC will automatically power the device from the boat’s batteries and provide both USB and NMEA 0183 data.
