Choose a Location
  • Near access to your vessel's instrument bus and a DC : 5-24V power supply
  • As far from engine vibration and moisture as is practical
  • 20 cm / 8 inches from occupants, as with any Wi-Fi device to minimize interference and EM
Mount the DMK Box

  • Mind the gasket placement when you replace the case cover
Power the DMK Box
  • Connect the brown wire from the ribbon to a +5-12V DC power source
