Disengaging GPS 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 NMEA0183 data on a pair of
wires which are connected to the GPS In terminal connections inside the
KAP-833. The data generated must include at least on of the following.
GPS Mode 5
For use when interfaced to a GPS generating NMEA 0183 data output. While in
auto mode this allows the autopilot to be directed by the GPS, enabling automatic
heading changes and eliminating the effects of wind and tide.
The digital display indicates the course-to-steer, which will be the bearing
between the origin and destination waypoints, plus a factor to correct for the
current cross-track-error (XTE).
Pressing the Auto key will set the KAP-833 to Auto Mode.
Pressing the Standby key will return the pilot to Standby.
The APA sentence.
The APB sentence.
The BOD and XTE sentences.
If only the XTE data sentence available, the pilot can steer in a restricted
manner. See later in this section.

When in any mode, press the GPS key. A beep will sound and the
adjacent yellow light will be turned on.
The vessel will begin turning from its current course to the course
requested by the GPS unit, at a maximum rate of 10 degrees per second.
If no GPS data is being received by the KAP-833, the autopilot will lock
onto the course of the vessel at the time that GPS Mode was engaged, and
the No GPS Data alarm shall sound.
