A028 NMEA 2000 AIS + GPS receiver

SKU: QUA-0005

The A028 combines dual-channel AIS and GPS Data and provides your data through NMEA 2000 and NMEA 0183 simultaneously.

Simply plug and play with your NMEA 2000 network, for the ultimate convenience and flexibility, no configuration required.

3 simultaneous data output connections:

  • NMEA 2000 network connection to your N2K backbone will provide AIS and GPS data to your complete N2K network, chart plotter, radio, and other connected devices and instruments. (including informing your navigation software for plotting waypoints and collision avoidance.)
  • NMEA 0183 RS422 output
  • USB output to a laptop of your choice (or USB OTG tablet or phone)

The advantage of an integrated GPS is that you can see, not only where other ships are, but crucially where you are in comparison with them and the coastline.

The ideal AIS and GPS multiplexer for your convenience.

QK-A028 has the following connections/indicators:

  • AIS antenna connector. Standard BNC female 50 Ohm connector. An active VHF antenna splitter is required if one VHF antenna is shared by QK-A028 and VHF voice radio. (We recommend separate antennas ideally.)
  • GPS antenna connector: Powered SMA connector for 50 Ohm GPS antenna. Built-in GPS module. An integrated GPS unit supplies positional data in addition to the AIS data. Simply connect the chosen GPS antenna.
  • NMEA 2000 (N2K) connection. NMEA 2000 network cable integral to the A028 for easy plug and play connection to your NMEA2000 backbone. The majority of all NMEA 0183 messages are converted to NMEA 2000, full list of conversions can be found in the manual.
  • NMEA 0183 output connectors. QK-A028 can be connected to NMEA 0183 RS422 AIS or GPS compatible equipment including chart plotters and multi-functional displays. NMEA 0183 RS 422 cable included for ease of connection. (also connects to NMEA 0183 RS232 when used with the Quark-elec Protocol Bridge (AS03)
  • USB connection. A micro USB port outputs NMEA 0183 messages.
