TMQ AP56 - SS37
Overview of Operation
Operation of the display unit buttons
or mode selection on a remote unit
will select one of the possible steering
modes in the C-Drive amplifier. It is
the C-Drive, which generates signals
to the steering motor.
The following is a brief list of the
capabilities of the autopilot. Each is
described in more detail in a separate
chapter.
MANUAL Mode: “H***”
The autopilot Display Unit shows the
current magnetic heading.
The vessel is under manual steering
control; the autopilot will not apply
any steering control.
AUTO Mode: “A***”
The autopilot will maintain your
vessel on any desired magnetic
course. This course can be set from
the Display Unit.
GPS Mode: “A***”
When receiving information from a
GPS unit, the autopilot can steer
a vessel to a precise latitude and
longitude, or through a sequence of
latitudes and longitudes.
RUDDER and RESPONSE Settings:
These customise the AP56 Autopilot
for your vessel’s steering. They may
also be used to adjust for varying sea
conditions.
COMPASS CALIBRATION:
The AP56 compass can be calibrated
on the vessel using a simple
procedure.
RUDDER ANGLE DISPLAY:
The AP56 Display Unit LCD can be
set to display the rudder angle as a
numeric number.

backlighting can be turned on.
