NMEA Gateway Connection
Do not use an existing gateway connected to an existing NMEA
2000 network. The CAN2 network is not NMEA 2000 compliant,
and there is a risk that an otherwise minor failure on the NMEA
2000 bus could interfere with the EST operation.
Connect the NMEA 2000 gateway to the engine bus and to a tee
on the CAN2 network as shown in figure 3-9.
