QK-A024 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-A024 and VHF voice radio. (We recommend separate antennas ideally.)
  • USB connector. A micro USB connector supplies power to the unit and also outputs the NMEA messages. It can also be used for adjusting parameters using the GUI Configuration software.
  • WiFi. Connectivity in both Ad Hoc and Station Modes on 802.11 b/g/n.
  • NMEA 0183 output connectors. QK-A024 can be connected to other AIS and SeaTalk compatible equipment (eg. wind/ depth or heading sensors) QK-A024 sends out NMEA 0183 messages via WiFi, USB, and NMEA outputs simultaneously for the chart plotter.
  • Check the LED lights. QK-A024 features three LEDs that indicate power (top, red) and AIS (centre, green), and GPS* (bottom, green) status respectively. The AIS LED will flicker at a fast rate when signals are received. *As GPS is not fitted on this unit the GPS LED performs no function.
