R220U AIS Receiver with NMEA and USB

SKU: INT-0064


The R220U is a high-performance, dual-channel AIS receiver with NMEA 0183 and USB outputs. 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 and 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 an external 12/24VDC will automatically power the device from the boat’s batteries and provide USB and NMEA 0183 data.
