NMEA
The NMEA (National Maritime Electronics Association) protocol is an
internationally accepted serial communication interface standard for
sharing data between electronic equipment. Raymarine products can share
information with non-SeaTalk equipment using the NMEA 0183 protocol.
response
The autopilot response level controls the relationship between course
keeping accuracy and the amount of helm/drive activity.
rudder gain
Rudder gain is a measure of how much helm the autopilot will apply to
correct course errors. The higher the setting the more rudder will be applied.
SeaTalk
SeaTalk is Raymarine’s proprietary communication system. It links the
products to provide a single, integrated system sharing power and data.
SeaTalk bus
This refers to the continuous SeaTalk system connecting together a series of
Raymarine units.

WindTrim
WindTrim (wind response) controls how quickly the autopilot responds to
changes in the wind direction. Higher wind trim settings will result in a pilot
that is more responsive to wind changes.
