Glossary 37
NMEA The NMEA (National Maritime Electronics Association) protocol is an interna-
tionally 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 prod-
ucts 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.
SM Statute (land) mile.
VHF Very High Frequency (radio).
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.
XTE Cross track error.
Yaw The boat’s rate of turn (°/sec).
