Setting up your GPS Unit
Because there are a great variety
of GPS units that will work with this
autopilot, the following is a guide only.
For more information, consult your
GPS manual.
The GPS unit must be set up to
output “NMEA 0183” data at 4800
baud on a pair of wires, which are
connected to the SP-110C unit via
the rudder feedback connector. The
data generated must include at least
one of the following:
• The APA sentence.
• The APB sentence.
• The BOD and XTE sentences.
• If only the XTE data sentence is
available, the pilot can steer in a
restricted manner only. (See later in
this section.**)
The GPS unit must be programmed
and activated to navigate to a
waypoint, or to follow a line joining
two or more waypoints (called a
route). This unit should then send
information to the autopilot from
which can be calculated the course-
to-steer.
Under the following conditions:
• Several waypoints are linked
together into a single route,
• The GPS unit is set and capable of
“auto-sequence” between them,
• An “arrival zone” of more than
0.05 NM (Nautical Miles) is set so
that the GPS can detect when the
vessel has reached a waypoint;
then the SP-110C will be able to
steer from each waypoint to the
next without intervention.
