Disengaging GPS Mode:
Pressing the AUTO button will return the AP55 to Manual Mode.
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 on a
pair of wires, which are connected to the NMEA socket on the
AP55 C-Drive unit. 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.
