OK, 492/498 only has one nmea output, the other is a CAN output (nmea2000).
So the connection to the autopilot should be made with the BLUE cable of the power/data cable, this goes to the positive (+) NMEA IN terminal of the autopilot.
Depending the model that would be the back of the display (ST4000/5000 series) , the back of the cockpit
connector (in tiller pilots) or the connectors in the course computer (S1/3, Type100/300, X series, et al)
Then connect negative (shield) to the - NMEA IN as well. This should be done bridging the BLACK Garmin negative cable and sending it to the pilot, but as shield is shared all around the boat
, if for some reason this becomes difficult, I sometimes bridge NMEA IN - with the negative from 12V in the AP. should work
, but the correct way to do it is with a direct connection of both + and - between the equipment
you intend to share data.
Remember to program the Comm SubTab for NMEA IN/OUT. good luck. alex
