On On
1. The Gateway module is connected to both a functioning CAN bus and NMEA 2000
bus. Data will be transferred as required.
2. Update/verify chartplotter software (consult manufacturer's website).
3. If Data is not being transferred NMEA 2000 bus device ID's are not approved and
are being blocked. Contact Mercury Marine service for helm Gateway (autopilot)
device approval list.
