* Vaux voltage is the same as the plotter’s input voltage.
If sent by the position sensor, the following NMEA messages
are transmitted to external devices (e.g., autopilot):
APB - XTE - RMB - BWC - GLL - VTG
The GEONAV will add the following messages (if received
from the position sensor):
GGA - RMC - ZDA
Auxiliary connector (7 pins)
Allows connecting the GEONAV to an
auxiliary instrument equipped with
NMEA 0183 interface (e.g., echosounder
and mast head transducer).
