You should install this cable only if you are building a NMEA 2000 network. Do not install this cable if
there is an existing NMEA 2000 network on your boat.
You must connect the NMEA 2000 power cable to a 9 to 16 Vdc power source.
NMEA 2000 network
You must connect the helm control to the same NMEA 2000 network as the other autopilot components
using the included T-connectors.
If there is not an existing NMEA 2000 network on the boat, you can build one using the cables and
connectors supplied in the autopilot corepack. See the installation instructions provided in the corepack
