The d10 has a single 8 pin M12 wired connector. Power (anything from 5 to 38v) is provided to the d10 via this connection. A cable is included.
There are the following options for connecting sensors to the d10.
1: The pulse signal from a paddlewheel such as the Airmar ST300 or Signet 2526 can be connected directly to the d10.
2: 2 NMEA0183 devices can be connected at 38,400 and 4,800 BAUD. Typically this is used for the depth from a triducer and a mast head unit such as the LCJ CV7-C
A separate converter cable can be used to connect the d10 to NMEA2000.
OUT: The d10 can act as a WiFi Access Point for other devices sending NMEA0183 or Signal K v1 delta JSON.
