Introduction
This manual should only be read in conjunction with the associated electric
amplier (C-Drive MCU) or autopilot control unit (AP4/AP9).
The AP56 Display is the main control panel used in conjunction with a C-Drive
Steering amplier to form an AP56 Autopilot System. It provides the means to
fully control the autopilot system, indicating in dierent modes heading, course
to steer and rudder angle.
When factory congured as a remote display (Part # AP56REM), it can be
used as a second control station for the AP56 Autopilot only.
In addition the standard display (Part # AP56HEAD) can be used as a second
station control for TMQ autopilot models AP4 and AP9.

System Overview
The AP56 Display head utilises the
C-Drive assembly and provides full
control of the autopilot, indicating in
dierent modes heading, course to
steer and rudder angle.
The C-Drive assembly is housed in
a rugged black aluminium case and
requires a supply voltage of 12 or 24
volts DC.
The rudder feedback unit (RFU) is
attached by linkage to the steering
tiller device in such a way that it can
accurately measure the movement
of the ship’s rudder and is also
electrically connected to the C-Drive
unit.
The compass detects magnetic
heading of the vessel and is
connected to the C-Drive assembly.
The rudder actuator (drive) system
provides the physical movement to
the rudder responding to the direction
control signals provided by the
C-Drive system.
Rudder actuator systems may
comprise any of the following:
1. Hydraulic ram controlled by either:
• Solenoid valves tted to an existing
power steering system.
• Solenoid valves connected to a
continuous running pump set.
• Hydraulic reversing pump unit
connected into an existing hydraulic
steering system.
2. Mechanical reversing drive unit
with reduction gears to drive the
steering system.
3. Linear actuator either hydraulic or
mechanical connected to a
steering tiller (or quadrant).

autopilot is attempting to achieve.
Waypoint Steering.
When interfaced to a GPS the
autopilot is able to steering along a
route pre programmed into the GPS.

The autopilot is able in accept
heading data from an external source
(eg: GPS compass or E-Compass) in
NMEA 0183 format

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 amplier. 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:
When using the autopilot at night, the
backlighting can be turned on.
REMOTE AUTO Mode: “ r *** ”
With a hand remote, panel remote,
steering lever or steering wheel
station installed, this will allow
steering by compass with the desired
course adjustable from the remote
station.
REMOTE POWER STEER
Mode: “ r *** ”
With a hand remote, panel remote,
steering lever or steering wheel
station installed, this will allow control
of rudder position from the remote
station.
POWER ON/OFF
The power to the C-Drive motor
control unit should be via a suitable
circuit breaker. Turning this on will
provide power for the C-Drive unit
and the AP56 Display Head.

Initial Settings
Selecting the Initial settings of the
Autopilot:
A number of system settings may
need to be carried out prior to
using the AP56 Autopilot. Two initial
settings can be carried out using
the display controls; other settings
include special remote mode or
C-Drive parameters which are set
using a computer with Hyperterm
(or another type of COMS Terminal)
program.
The display adjusted settings are:
• Rudder Limits
• Compass Calibration
Rudder Limit Set
The rudder limits prevent the steering
motor driving the rudder beyond its
physical (mechanical) stops. The
limits are factory set to 30º and
should not need changing. However,
the limit setting can be set from the
display if deemed necessary.
Setting limits:
• Move the rudder to the required
port limit position
• Press MODE button ve times
• Display will read PL - - (- - is the
port rudder angle º )
• Press ◄ and ► buttons together
• Port limit is now set
• Move rudder to the required
starboard limit position
• Press MODE button
• Display will read SL - - (- - is the
starboard rudder angle º )
• Press ◄ and ► buttons together
• Starboard limit is now set
• Press AUTO
• Display should now revert to read
heading (H***)
NOTE:
• If “oor” (out of range) is displayed,
it indicates the rudder is not in the
correct position to set the rudder
limit. ie: Rudder is to port when
setting the Starboard limit.
• If at any time during testing the
motor runs under load and the
rudder does not move, checks
should be carried out to conrm the
limit switches are operating prior to
the rudder running into the stops.

Rudder Limit Reset
It is possible to reset the rudder limits
to the factory settings if unsure of
the settings when adjustments are
carried out.
To reset rudder limit to factory
default:
• Press the MODE button seven
times
• Display will read r L r
• Press ◄ and ► buttons together
• Rudder limits are now reset to
factory default setting
Compass Calibration
The standard TMQ compass
(COMMAG or E-Compass) supplied
as part of the AP56 autopilot system
has been calibrated after manufacture
and this calibration will be satisfactory
for most installations. If you have a
steel vessel, or some other factor
which causes the compass to perform
poorly, the calibration procedure will
adjust compass characteristics to
compensate.
NOTE: The calibration should only be
done if the compass is known to be
inaccurate when compared to a chart
bearing.
If the AP56 compass heading
displays a constant oset when
compared to a correctly calibrated
ships compass (eg: the autopilot
compass reads 3 degrees high on all
headings), simply rotate the compass
sensor to align the displayed
headings with the ships compass.
In this case it is not necessary to
re-calibrate the compass as
described below.
If the AP56 has inconsistent variation
on dierent headings, the following
calibration procedure can be carried
out. This procedure should only be
done in calm waters with adequate
sea room. AUTO mode must not be
selected to carry out the calibration.
To calibrate compass:
• Press MODE button eight times
• Display will read CCAL
• Press ◄ and ► together to start
calibration
• Display will read StrC
• Commence turning the boat slowly
in one direction for two full circles
(720º). Each circle should take a
minimum of 1 minute.
• On completion of the turns press
◄ and ► together to store the
calibration.
• Display will revert to read heading
• Check the compass alignment by
steering boat due north 000º by
boat’s compass
• Rotate autopilot compass (if
necessary) so that display also
reads 000
NOTE: The eectiveness of the
compass calibration is dependent upon
all steps being completed. Should you
wish to abort the calibration procedure
at any time during the process, simply
press MODE button to return the pilot
to MANUAL.
