Warnings
• The autopilot is a navigational
aid; an adequate watch must
be maintained at all times when
autopilot is in use.
• The autopilot must be placed in
manual mode when the vessel
is stationary as the system may
continue to drive the rudder to the
end of its travel and damage to the
system may result.
• It is strongly recommended that
the autopilot not be used while
navigating in restricted waterways
as water currents, wind changes or
radio transmitter interference can
endanger your own or other vessels.
• It is recommended to install a
rudder feedback unit for best
performance; otherwise the system
will not operate in auto / gps mode
unless the vessel is moving at a
congurableminimumspeed.

Important Installation
Notes
• Access for wiring must be provided.
cables will possibly need to be
run or extended if required, to the
vessels switchboard, SP120C
display, e-compass, rudder
feedback(iftted)anddriveunit.
• SP120C cables and equipment
must be located as far as possible
from transmitting equipment and
cables (e.g. radio aerials and
aerial cables, radars, inverters,
ect) to prevent electro-magnetic-
interference.
• The e-compass must be mounted a
minimum distance of 1 meter from
other magnetic compasses, radios,
speakers, transmitting equipment
or other products with magnetic
properties, to avoid interference.
• The SP120C must have a direct
connection to power supply via a
15 amp circuit breaker or a 15 amp
fused circuit and an isolating switch.

(optional)
Additional Equipment Required
(not standard supply)
1. Drive motor – to allow the

pump-set, tapped into the
existing hydraulic steering
system or;
• A constant running hydraulic
pump with direction control
solenoids.
A mechanical steering system will
require;
• a reversing mechanical drive,
connected to the existing
steering ram mechanism.
2. Termination hardware;
• Terminal blocks (suitable for

• Circuit breaker / switch (15A
rated)
• Wiring extension cables / ferrules
/ crimp lugs & related crimp tools

SP120C - Control Display Unit
• Steering control system for 4.0m -
16m vessels;
• ‘Virtual Rudder Feedback’ feature,
where no RFU requires to be
installed.
• 3 Control Modes – Manual Mode,
Auto Mode and GPS mode
• Live indication for ‘Steering mode’,
‘Position & Waypoint Info’, ‘Heading’,
‘Course to Steer’, ‘Rudder angle’,
‘System Voltage’ and ‘Drive Current’
• Supports all current NMEA-0183
interface standards;
• Heading: HDG, HDT, THS, HDM/
ROT & COG
• GPS: APA, APB, XTE, BOD, BWC &
RTR *for GPS steering mode
• GLL, RMC, SOG, VTG *for visual
indication and assisting AUTOPILOT
control
•30cmy-leadfordrivemotorand
power connections
• 6 pin LTW connectors for Compass
and Rudder/NMEA-0183 interfaces
• Power: 12-24 Volts DC (Up to 29V
During Charging)
• Drive output up to 35A. *If current
exceeds 35A, the drive output is
inhibited.
• Software controlled rudder limits,
inhibits drive control at each
mechanical limit.
• Additional auto switching fail
safes, in case of failure of RFU or
E-compass;
• If RFU fails, the system will
revert to Non-RFU mode
automatically.
• If a GPS system is connected
and the standard supplied
E-Compass fails, the SP120C
system will automatically revert
to GPS ‘COG’ mode for heading
reference.

SP120C CDU Installation
Dimensions
SP120C CDU Installation Guide
- The SP120C Head unit should be
mounted in a position accessible to
the steering position and protected
from direct rain or salt water.
- For in dash mounting cut a 75mm
(3.0”) hole
- An optional mounting bracket
is available and may be used
for desktop mounting - see your
supplier
- Drill mounting screw holes
- Mount the display using screws
supplied (304 SS – 6G)
NOTE: Use the protection cover
when the system is not in use, to
protect the screen and casing from
UV and other physical damage
ELECOM
Electronic Compass
(E-Compass V.3)
Take care when handling the
compass as it is a sensitive piece of
equipment.
The compass position is the most
important item in the installation of
the autopilot. Good course holding
is dependent on the compass being
free from magnetic interference and
excessive rolling or pitching.
E-Compass Specications:
• Output based on NMEA 0183
standards
• Protocol Settings: 4800–8–N–1
• Output Sentences: HDM & ROT
• Power supply: 12-24 VDC <1Watt
• No moving parts to prevent
mechanical wear-out, small size and
high reliability.

• Solid state electronics with tilt and
roll compensation up to 35degrees.
E-Compass Installation Guide:
• IMPORTANT! The compass must
bettedinanareaatleast1meter
away from steel objects.
• Avoid positions near radios,
speakers, aerials, antenna cables or
any other current carrying cables.
• Select a dry position free from
magnetic interference.
•Ifsystemisttedtoasteelhull
vessel, the compass must be
mounted at least 1m above the steel
structure on a non-magnetic post or
bracket (aluminium and wood are
good options in this case)
• A lower / aft mounted position along
the centre of the hull is preferred, to
reducetheinuenceofvesselroll
and pitch.
• Check other side of bulkheads and
deck heads for magnetic interfering
type objects before mounting.
• Mount the compass horizontally
with the arrow (bow) pointing to the
front of the vessel, preferably on a
stainless steel, wooden or plastic
bracket.
• Use non-magnetic screws to mount
the compass unit (316 grade
stainless steel)
•Theunitmustbemountedonaat
horizontal surface.
• Before selecting the E-compass
installation position, it is good to
test the installation position is free
from interference by checking the
location with a portable magnetic
compass.

Rudder Feedback Unit
Rudder Feedback Unit (RFUS)
The RFU is optional, although
recommended for the best possible
performance on some types of
vessels.
For example: A RFU must be
installed on vessels with high sides
that are sensitive to winds turning the
boat, or high powered 5-6m Deep V
(22-25 deg dead rise / 175HP+) type
vessels used in rough seas and high
winds. Or any other vessels that are
overly sensitive and very responsive
to small amounts of ‘rudder’ at high
speeds.
When the RFU is installed, the
congurationsettingsaresimplied.
Non-RFU mode is slightly more
complicated.
NOTE: The RFUS is factory aligned.
The arm should not be removed or
loosened. It is also water resistant,
however, if mounted in a wet position
some protection should be provided
to prevent water damage or physical
damage.
RFU Installation Guide
1. Refer to installation diagram and
installation template supplied with
the unit
2. Mount rudder feedback adjacent to
the tiller (NOTE: rudder feedback
movement must copy the angular
movement of the tiller like a
pendulum)
3. Use a mounting bracket if required.
4. Note the markings on the rudder
feedback unit. ‘P & S’ (Port and
Starboard) to check ruder moves
in the correct direction, manually,
before testing on the water.
5. Check installation is suitable
by slowly moving the steering
manually, to ensure:
a. The direction indicated on the
top of the RFU is correct
b. No undue mechanical strain
is placed on the feedback
or linkage. (Also check for
strain when the tiller is tilted
upright (for outboard engine
installations)
6. To complete the install, use the
SP120C advanced menu to
calibrate the rudder limits and
centre point of the RFU.
