Comar R450-D Series Network AIS Receiver
The Comar R450-D Series is the direct replacement for the legacy R400N,
delivering the same compact, professional AIS reception platform with updated
networking and built-in Wi-Fi. Designed for shore-based and coastal monitoring,
the R450-D decodes Class A and Class B AIS transmissions, as well as Aids-to-Navigation
(AtoN) and SART messages, outputting reliable NMEA-0183 data for integration into
charting systems, monitoring platforms, and data services.
The R450-D provides multiple output options — Ethernet (Digi® network module),
USB (virtual COM), and integrated 2.4 GHz Wi-Fi with AP / STA / AP+STA modes.
Configuration is simple via the built-in web interface. For users requiring GPS,
the R450-DG model adds an integrated GPS receiver with standard NMEA GPS
sentences (GPGGA, GPRMC, GPGSV, GPGSA).
- Dual-channel AIS reception (Ch A 161.975 MHz, Ch B 162.025 MHz) for complete coverage
- NMEA-0183 data output over Ethernet, USB, and Wi-Fi
- Wi-Fi module supports Access Point, Station, or AP+STA operation with full configuration through the web interface
- Digi® network module with robust UDP/TCP client/server capacity (up to 32 simultaneous UDP connections)
- Compact ABS enclosure, easy flat-surface mounting, IP40 rated
- Optional R450-DG adds GPS data output alongside AIS
