NMEA cable connectors
 NMEA connections are made using spade connectors.
 When fitting the spade connectors, make sure the connector fits
securely over the blade and not between the connector and its plastic
insulating boot  incorrect fitting will give intermittent contact
which will lead to faulty autopilot operation.
NMEA data transmission
If you wish to transmit NMEA information to other equipment a
SeaTalk Interface should be installed.
