1 GENERAL INFORMATION
1.1 Introduction
Congratulations on the purchase of your new Simrad AP35 autopilot system
and thank you for selecting what we feel is the most advanced autopilot
system available on the market today.
Today Simrad manufacture a complete range of autopilots for all types of
vessels, from leisure boats up to advanced steering systems for merchant
marine vessels. Our factory for these products Simrad Egersund AS, is
located in Egersund on the south/west coast of Norway. The company's
involvement in autopilots began in 1953 with equipment for the North Sea
fishing fleet under the brand name Robertson. Professional mariners around
the world acknowledge that the Robertson and Simrad brand names are
synonymous with the absolute best in autopilot technology.
The AP35 autopilot from Simrad represents yet another step forward in
autopilot technology with the intent to provide small fishing boats and work
boats up to 45 feet with a host of new features. The system can be expanded
and enhanced with a selection of options and accessories.
The brain in the AP35 autopilot system is the single "intelligent" junction
unit that communicates with all other system modules on the ROBNET
network. The ROBNET has been developed to establish a reliable digital
communication and power distribution network between the units in the
system. The ROBNET simplifies installation and enables the AP35 system
to be easily expanded at any time. Any unit that is connected to the autopilot
system via Robnet is called a Robnet Unit (See table on page 11).
1.2 How to use this manual
This manual is intended as a reference guide for operating, installing and
maintaining the Simrad AP35 autopilot. Great care has been paid to simplify
operation and set-up of the AP35, however, an autopilot is a complex
electronic system. It is affected by sea conditions, speed of the vessel, hull
shape and size.
Please take time to read this manual to get a thorough understanding of the
operation and system components and their relationship to a complete AP35
autopilot system.
Other documentation materials that are provided with your system include a
warranty card. This must be filled out by the authorized dealer that
performed the installation and mailed in to activate the warranty.

1.6 Rudder Feedback units
RF300 Rudder Feedback Unit
Rudder feedback unit with transmission link and 10 m (30 feet) of cable.
Transforms the angular travel of the rudder to a digital signal read by the
autopilot steering computer.
RF45X Rudder Feedback Unit
This unit transmits two electrical signals proportional to the rudder angle.
One signal operates as a feedback for the autopilot, the other as drive signal
for rudder angle indicators. The unit is mounted close to the rudder stock and
is mechanically connected to the rudder by the RF45 Transmission link.
1.7 Heading Sensors
The AP35 autopilot can be used with the following combinations of heading
sensors:
RFC35 Electronic Fluxgate Compass
A compact heading sensor from Simrad with 15 m (45 feet) of cable. The
direction of the earth's magnetic field is sensed by a floating ring core in a
fluxgate coil and transformed to a digital signal read by the autopilot steering
computer.
Simrad AP35 Autopilot
12 22083083H
RC25 Rate Compass
Fluxgate compass with integrated rate of turn sensor. Provides a dramatic
improvement to the dynamic performance of both the autopilot and a
stabilized radar display.
Same dimensions as RFC35.
CDI35 Course Detector Interface and
CD100A (CD109) Course Detector
Interface and sensor unit to connect AP35 to a magnetic compass. The AP35
provides excitation current for CD100A and converts the analogue sin/cos
signal to digital two wire format for the autopilot steering computer.
NMEA compass
Any NMEA 0183 compass with HDT, HDG or HDM messages can be
connected directly to the J300X/J300-40X junction units.
Other compass models
The optional CI300X can interface AP35 to fluxgate compasses with
heading signal on a sine/cosine format or gyro with 1:1 synchro.
1.8 Optional equipment
A series of options are available for the basic AP35 system.
R3000X Remote Control
A small handheld remote control with two push buttons for power steering
or course selection (port and starboard), and one push button with built-in
lighted indicator for mode selection.
S35 NFU Steering Lever
S35 is designed for indoor and outdoor bulkhead mount and made of shock
resistant polyxymethylene. The lever has spring loaded return to midposition. A push button with light indicator is used for mode selection when
connected to a Simrad J3XX junction unit.
FU50 Follow-Up Steering Lever
The FU50 Follow-up steering lever features a dial (scale) with 5° rudder
angle markings. The rudder will move and stop at the angle selected on the
dial. The FU50 has a mid-position indent, buttons for (limited) mode
selection, and mode indicators (STBY, FU, AUTO, NAV, WORK, and
THRUSTER*). It is designed for indoor and outdoor bulkhead- or panelmounting. Refer to the FU50 manual.

Caution ! An autopilot is a very useful navigational aid, but DOES NOT under any
circumstance replace a human navigator.
Do not use automatic steering when:
• In heavy traffic areas or in narrow waters
• In poor visibility or extreme sea conditions
• In areas where use of autopilot is prohibited by law
When using an autopilot:
• Do not leave the helm unattended
• Do not place any magnetic material or equipment near magnetic or
fluxgate compass used in the autopilot system
• Verify at regular intervals course and position of vessel
• Always switch to Standby mode, and reduce speed in due time to avoid
hazardous situations
2.1 Overview
Figure 2-1 AP35 Front Panel
The control unit shown above can operate as a stand alone unit in an
autopilot system or combined in a multistation system. In a multistation
system the command can easily be transferred from one unit to another.
Units not in control will display "Inactive".
The AP35 system is capable of the following primary steering modes: STBY
(manual steering), AUTO, NAV, WORK and TURN, each mode having a
dedicated push button.
Each of the mode push buttons is clearly identified with the primary function

2.9 Automatic Steering
The AUTO mode is used to make the AP35 steer the boat automatically on a
set heading. AUTO is always available from any mode or function within the
AP35 by a single push on the AUTO button. When the AUTO mode is
selected, the AP35 automatically selects the current boat heading as the set
course and the current rudder angle to compensate for wind/current.
Note ! If Init Rudder “Midship” is selected (see Dockside settings, page 73 the
rudder will move to midship (0
°
).
In AUTO, the AP35 is issuing rudder commands to keep the boat on the set
heading. Determination of the boat heading is provided by the magnetic
compass course detector or RFC35 Fluxgate Compass (or an optional
heading sensor) for course keeping in AUTO mode.
The AP35 will keep the boat on the set heading until a new mode is selected
or a new heading is set with either the course dial or the PORT or STBD
buttons. One revolution of the dial equals 45° course change.
Once the course is changed to a new set heading, the boat will automatically
turn to the new heading and continue to steer straight.

2.10 Automatic Speed selection
The AP35 provides two different sets of steering parameters for controlling
the response of the boat at different speeds (HI or LO) while in AUTO and
NAV modes.
The AP35 always selects the HI speed steering parameters when first
switched on. This is a safety feature. After initial turn on, selection of the
steering parameters is done automatically, based on the availability of input
data from either an external speed log or an external navigator, or manually.
The AP35 automatically selects the HI or LO parameter set. The speed at
which the AP35 changes from HI to LO (or opposite) is determined by the
"Transition Speed" set in the Installation Setup Menu.

2.12 Navigating with the AP35
The AP35 has the capability to use steering information from an external
navigator (GPS, Chart Plotter) to direct the boat to a specific waypoint
location, or through a route of waypoints. In the NAV mode, the AP35 uses
the heading sensor as it's source of heading for course keeping. The steering
and speed information received from the external navigator alters the set
course to direct the AP35 to the destination waypoint.
Note ! Navigational steering must only be used in open waters. The process of
having an external navigation receiver direct an autopilot can be a slow
acting process. By selecting the NAV mode, the AP35 is set for automatic
steering on the current set course and then waits for the user to accept the
course change to the destination waypoint.
To obtain satisfactory navigation steering, the following points must be
fulfilled prior to entering the NAV mode:
• The AP35 autosteering must be tested and found satisfactory.
• The navigation receiver must be operating and the navigation system
(GPS, Chart Plotter) must be in full operating mode with adequate signal
characteristics for valid position and steering data.
• At least one waypoint must be entered and selected as the current
waypoint in the navigation receiver.
• The navigation source in the AP35 USER SETUP menu must be set for
the navigator that contains the current waypoint.
The AP35 is designed to steer in “mixed mode” operation. This combines
the straight steering capability of cross track error (XTE) steering in
conjunction with the turning capability of bearing mode steering (course to
steer (CTS)).

When operating the AP35 in NAV mode to automatically steer through a
route of waypoints, the AP35 will steer to the first waypoint in the route after
you accept the first waypoint as the location to steer to. When you arrive at
the waypoint, the AP35 will display an alert screen with the proposed new
course information displayed. If the required course change is more than 10°
you will need to verify that the upcoming course change is acceptable.
Verification is performed by pressing the NAV button after the alert screen
is displayed. If no verification is received, the AP35 will continue on the
current set course in AUTO mode.

details on selecting a different Navigator.
Note ! If the AP35 is connected to a Nav. receiver that does not transmit a message
with bearing to next waypoint, it will pick a XTE message and steer on Cross
Track Error only. In that case you have to revert to AUTO mode at each
waypoint and manually change set course to equal bearing to next waypoint
and then select NAV mode again.

2.13 WORK-mode
The WORK-mode is an automatic steering mode to be used under

At such incidents some boats may need a rudder off-set when steered by
hand. By selecting WORK-mode directly from STBY-mode the rudder offset is maintained and becomes the TRIM value.
When in WORK mode a quick double press on the WORK button will
access the TRIM display and the rotary course dial can then be used to adjust
the trim value if needed. The (manual) trim compensates for the autotrim
which needs time to build up the appropriate rudder off-set. The TRIM
setting is not stored.
A different RUDDER (GAIN) setting may be preferred in WORK mode as
compared to that in AUTO (Lo)-mode. A second quick double press on the
WORK button following that for the TRIM display will give access to the
RUDDER display. The RUDDER value can then be set by the course dial.
The RUDDER value set in WORK mode will be stored in the AP35 memory
and is automatically recalled when returning to WORK mode.

The LO (speed) parameters of Counter Rudder (C-RUDD) and Autotrim are
automatically selected in WORK mode. The autotrim function and the Offcourse alarm are controlled by speed input and are automatically turned off
at speeds below 2 kts. If no speed input is provided the autotrim is
permanently on and the Off-course alarm operates as in AUTO mode.
If you prefer to have complete manual control of the rudder trim in WORK
mode, the autotrim can be permanently disabled at the installation setup.
From software version V1R2 onwards the off course alarm is permanently
disabled in Work mode. See your s.w. version on initial start-up.
Note ! Pair-trawling requires manual trim only, and the autotrim should be
permanently disabled at the installation setup.

2.14 TURN-mode
The AP35 provides special turn features when in AUTO or WORK modes.
U-Turn changes the current set course to be 180 degrees in the opposite
direction. The user may decide if the U-Turn should be made to Port or
Starboard to bring the boat on the new course. U-Turn is activated by a
single push on the TURN button. After the single push, the AP35 will
continue on the set course until you press either the PORT or STBD button
to select the direction to make the U-Turn. If you do not press PORT or
STBD within 1 minute, the AP35 will return to the AUTO mode and stay on

2.15 Dodging
The AP35 also provides the capability for dodging.
Dodging is useful in situations where you need to quickly take control of the
helm to steer around an obstruction, and then wish to return on the previous
set heading after performing the evasive manoeuvre. A quick double press
on the TURN/DODGE button activates dodging.
When in DODGE mode the course displayed is the current boat's heading,
however, the previous set course is remembered by the AP35. When
DODGE is displayed, the AP35 is no longer in control of the steering, and
you must either manually steer the boat or take control using either Non
Follow Up steering or Follow Up steering. On manual steering the clutch (or
bypass valve) in the drive unit will be disengaged when dodging. The AP35
will remain in the DODGE mode until you exit DODGE by a second press
on the TURN/DODGE button or select another mode.

In normal operation of multiple control units, control is accessible from
every control unit connected to the AP35 system. One control unit is "active"
and provides the user with access to all functions and enables the user to
change modes and set the course for automatic course keeping. All
remaining control units are "inactive" and have no effect on mode changes or
course selection. A single push of either the STBY (or AUTO or NAV)
buttons on an "inactive" control unit will allow transfer of command and
make it "active".

4 INSTALLATION
4.1 General
This section provides detailed information required to successfully install
AP35 Autopilot system
The AP35 system includes several modules that need to be mounted in
different locations on the boat, and also need to interface with at least three
different systems on the boat:
• The boat's steering system
• The boats electrical system (input power)
• Other equipment on board (NMEA interfacing)
In addition, the advanced capabilities of the AP35 require the installer to
perform a series of settings and tests to verify proper operation of the
system, refer to the check list below.

11. Provide the user with training (Page 89)
4.3 Unpacking and handling
Care should be taken when unpacking and handling the equipment. A visual
inspection should be made to see that the equipment has not been damaged
during shipment and that all components and parts are present according to
the packing list.
A standard scope of supply for an AP35 system will include:
• Control unit with standard installation accessories.
• Junction unit (J300X, J300X-40, J3000X) and one 15 m (49') Robnet
cable.
• RFC35 Fluxgate Compass with 15 m (49') cable attached.
• RF300 Feedback unit with 10 m (33') cable attached and transmission
rod.
• Appropriate drive unit for the installation (unless the AP35 is going to
operate an existing drive unit)
• Optional equipment that may have been ordered for the installation.
4.4 Determine system configuration
It is important to become familiar with the configuration of the system prior
to beginning the installation. The AP35 Basic system is shown in Figure 4-1.
Pay particular attention to the junction unit/drive unit combinations on page
51 and the chart on page 11.
As many of the units are communicating on a common network (ROBNET),
with identical connectors, the installation is simplified. Try to mount the
units within the standard cable length supplied with each unit, if possible.
ROBNET Extension Cable (10m) is available from your distributor.
Installation

4.5 AP35 System Layout
Figure 4-1 AP35 System layout with options
4.6 RF300 Rudder feedback
The RF300 Rudder feedback unit mounts close to the rudders, and is
mechanically linked to the rudder tiller arm or rudder quadrant.
Refer to Figure 4-2 for the recommended mounting arrangement. Note that
the RF300 transmitter arm has two slots for the transmission link. The slots
enable maximum flexibility to provide the 1:1 mechanical linkage
relationship.
Note ! Do not try to remove the transmitter arm from the feedback unit. The unit is
factory adjusted and need no further adjustment at installation than
described below.
As a starting point, it is desirable to set the transmitter rod to the inner limit
of the outer slot if possible. (Refer to Figure 4-2). Drill and tap the rudder
tiller arm so that the Y1 dimension is equal to the Y2 dimension (Use 4.2
mm drill and 5 mm tap). Attach the ball joint to the tiller arm, and connect
the transmitter rod to the ball joint at the rudder tiller arm.
Turn the helm wheel to set the rudder tiller arm to approximate centre
position.
Rotate the RF300 transmitter lever until it is set to centre position. (Use the
alignment mark to line up the transmitter lever to be opposite the cable entry
into the feedback.)
Note ! Carefully observe the alignment marks. A rudder feedback alarm may be the
result if the alignment instructions as per Figure 4-2 are neglected.
Simrad AP35 Autopilot
46 22083083H
Attach the transmitter rod to the RF300. Set the RF300 mounting location to
be in accordance with Figure 4-2. The centre of the RF300 should be in line
with the centre of the rudder post. Mount the RF300 to a suitable platform
using the screws provided. If necessary, add blocking material under the
RF300 to adjust the height of the transmission arm to be level with the
rudder tiller arm.
Figure 4-2 RF300 mounting (019356)
Note ! Due to space limitations, it may be necessary to cut the length of the
transmitter rod to move the RF300 closer to the rudder post.
Tighten the mounting screws for both the RF300 feedback unit and the
transmitter rod ball joint.
Have someone observe the RF300 while someone else turns the helm wheel
through the complete range of travel from full port to full stbd. rudder to
verify that the mechanical linkage to the RF300 is not obstructed.

4.7 RF45X Rudder Feedback Unit
The RF45X is normally installed with the shaft pointing upwards. It can,
however, be mounted with the shaft pointing downwards if this is more
convenient. The deflection can then be inverted as illustrated in Figure 4-5. An
“upside-down” installation will make access to within the unit more
convenient as the unit can be opened without moving it from the mounting
base. To open the unit, unscrew the two screws at the bottom and remove the
cover. Be careful with the wires when you put back the cover.
Figure 4-4 RF45X Rudder Feedback Unit - Mounting
Use the attached template (Drw. 22011225) to drill the required mounting
holes. The unit is fastened to the mounting base by the two Allen screws
enclosed. (Other types of screws may be used if fastened to i.e. a wooden
base.)
Make the parallelogram configuration of the transmission link (see Figure 4-4)
and temporarily fasten the link to the RF45X shaft. The transmission rod can
be shortened by cutting off a piece using a hacksaw. Move the rudder
manually h.o. - h.o. and make sure the transmission link is moving freely in
both directions.
Simrad AP35 Autopilot
48 22083083H
Electrical connection
Use a twisted pair cable AWG20 (0.5 mm2) between the breakout box and the
J3xx junction unit. The cable length is not critical but should be kept at a
minimum.
The cable should be connected to the junction unit according to Figure 4-5.
When splicing the cables in the breakout box, crimp the enclosed pins on
each wire of the extension cable. Otherwise the wires may be cut off at the
terminal point when the screws are tightened.
The screen is not terminated in RF45X and must be connected in the
junction unit.
Note ! The green and yellow wire is not used and must be isolated!
For final alignment, see page 75.

22083083H 49
4.8 Junction unit
The junction unit is designed to operate in a location that provides ambient
temperatures below +55°C (+130°F).
Note ! The junction units (J3000X, J300X and J300X-40) are not water proof and
should be mounted vertically as shown in a dry place between the control
unit and the drive unit.
Figure 4-6 J3XX mounting
Cable connections
Use only shielded cables. This includes Mains input, drive units and if
necessary for the extension of the RF300 Rudder Feedback cable. The
clutch/bypass cable and the solenoid cable should be 1,5 mm
2
(AWG14).
Signal cables should be 0.5 mm
2
(AWG20) twisted pairs.
The mains supply cable and the drive unit motor cable should have sufficient
wire gauge. This will minimize voltage drop and allow the drive unit to
operate at full power.
Refer to the table below for recommended cable sizes.

Grounding and RFI
The AP35 system has very good RFI protection and all units are using the
Junction Unit as common ground/shield connection. The Junction Unit
should therefore have a proper ground connection to the hull.
ROBNET cables and other signal cables (compass, feedback, NMEA)
should not be run in parallel with other cables carrying RF or high current,
such as VHF and SSB transmitters, battery chargers/generators and winches.
Figure 4-7 J3XX – Screen Termination
Remove the bottom cover to get access to the plug-in terminals. Strip about
1 cm (0.4") of the cable's insulation and pull the screen backwards to cover
the insulation. Position the straps as shown and tighten well to make sure the
screen has good contact.
Leave sufficient free wires so that the plug-in terminals can be easily
connected/disconnected.
Pull out each terminal before connecting the wires. Remove all strands
before putting on the terminal cover.

The relation between drive units, drive unit voltage, input voltage, drive
output and interfacing to steering gear are shown in the table below. The
AP35 system detects whether a reversible motor or a solenoid is connected
and outputs the correct drive signal automatically.
Refer to the connecting diagram for the different drive units on page 53
onwards.
Installation instructions for the drive units are found in the manual for the
individual units.

• Mount the two bracket halves to the Control unit.
• Temporarily bolt together the other two halves of the bracket to the two
other halves.
• Hold the Control unit in place by hand and mark the 4 holes for the fixing
screws on the mounting surface.
Installation
22083083H 55
• Remove the Control unit, drill the 4 mounting holes in the mounting
surface.
• Unbolt the temporarily fitted bracket halves and screw them to the
mounting surface.
• Assemble the complete bracket again and adjust the control head to best
viewing angle and tighten up the mounting bracket bolts.
• Connect the Robnet cables to the control unit connectors (See note on
next page).
Figure 4-12 AP35 Bracket mounting
ROBNET network cables
As Robnet units have 2 Robnet connectors they can be used as "jack points"
for further expansion of the system. There are no dedicated "in" or "out"
connectors. You may connect the cables to any available Robnet connector
on the specific unit.
The Robnet cables are available in 7 and 15 m length and provided with 6
pin male connector at one or both ends. The 15 m cable to the junction unit
has connector only at the control unit end.
Optional extension cable (10 m) is available and have a male and a female
connector.
When installing a system, try to minimize total Robnet cable length by
connecting all Robnet units to the nearest available Robnet connector.
Total length of Robnet cable installed in a system should not exceed 50 m
(165').

See table for pin configuration and color code of the network cable. DO
NOT MIX THE PINS AND THE CABLE COLORS!
Note ! Apply a thin layer of pure vaseline on the connector threads and make sure
the connectors are properly secured to the receptacle by the coupling ring.
The connectors are weather proof according to IP56, when properly
installed. All unused Robnet plugs must be fitted with the plastic cap to keep
the connector free of dirt and moisture. A separate screw cap for the Control

4.11 RFC35 Fluxgate Compass
Figure 4-14 RFC35 mounting
The heading sensor is the most important part of the AP35 system and great
care should be taken when deciding the mounting location. As the sensor
heading is displayed on the AP35 Control Unit, the heading sensor can be
mounted at any location where there is a minimum of magnetic interference.
Note ! An autopilot heading sensor should not be installed on the fly bridge or in
the mast.
The RFC35 compass can be deck mounted or on the bulkhead, athwart ship
or along ship. The heading offset feature in the AP35 will compensate for
the mechanical offsets that may be a result of the selected location and
orientation of the RFC35.
Simrad AP35 Autopilot
58 22083083H
If the RFC35 is deck mounted or bulkhead mounted athwart ship with the
cable gland pointing aft, little if any offset correction is required. With the
cable gland pointing forward a 180° correction is required.
When mounting RFC35 on a bulkhead along ship, a +90° or -90° correction
is needed dependent on whether it is a port or starboard bulkhead.
Select a location that provides a solid mounting place free from vibration,
and as close to the vessel's centre of roll and pitch as possible, i.e. close to
the water line. It should be as far as possible from disturbing magnetic
influences such as the engines (min. 2 meters), engine ignition cables, other
large metal objects and particularly the drive unit.
Use the supplied mounting kit and drill the holes through the centre of the
slots in the sensor or the mounting brackets.
Note ! The compass face plate on the RFC35 is the TOP. Never mount it upside
down! Level the sensor as close to horizontal as possible.

• Connect the Robnet connector to the AP35 Control Unit (or CI300X or
NI300X if installed), see Figure 4-16.
• Alternatively, if there is no free receptacle, cut the connector from the
cable and connect the wires in parallel with the wires going from the
junction unit to the control unit (see Figure 4-13). Do not connect the
yellow and the green wires and ensure that they do not connect with the
terminal or chassis.
• Select RFC = ROBNET in the Installation : Interface Setup.
• Select RFC as compass in the User Setup Menu.
• Perform the compass calibration as described on page 84.
Note ! After turning on, the compass will stabilize in less than 30 seconds, but it
will need another 5 minutes to get the full effect of the rate sensor.
Refer to page 84 to compensate for any permanent off-set after the
calibration is completed.
RC25 calibration data is stored in the compass and will not be deleted by a
Master Reset in the autopilot.

RI35 Mk2 illumination
Internal LED’s illuminates the scale. The illumination is turned on and
adjusted in three steps by pushing the front panel keypad.
Zero adjust
Note ! Prior to making a zero adjustment on the indicator, make sure the feedback
unit is installed and aligned according to it’s mounting instruction.
Follow the instructions on page 83 to zero adjust the rudder feedback.
Press and hold the illumination key for 5 seconds. The pointer will now
adjust itself to zero confirmed by a 1-second beep.
Note ! There may be a difference in the RI35 Mk2 and the autopilot reading. This is
normal because the autopilot zero adjust compensates for drag caused by
the hull, flaps etc. If you prefer the readings to be aligned, then put the
rudder amidships using the RI35 Mk2 as reference, and then zero adjust the
autopilot.
Simrad AP35 Autopilot
62 22083083H
Reversed deflection
On installations where the rudder feedback unit is mounted upside down, the
deflection of the pointer will be reversed. To make it correct, move the
rudder to approximately 10° either way then press and hold the illumination
key for 10 (ten) seconds. The pointer will then first travel to zero then
continues to the opposite side of the scale confirmed by a 2-second beep.
Note ! If you let go of key before confirmation of reversed deflection has been
given, the RI35 Mk2 will think you meant to do a zero adjust and leave the
pointer at zero. Then simply repeat the “Zero adjust” section.

4.18 Interfacing
With the AP35 autopilot system there are several possibilities to connect to
other equipment for data exchange:
1. J3000X includes a single NMEA input/output port.
2. J300X includes two NMEA input/output ports (NMEA heading 10 Hz to
port 2) and Clock Data interface to Simrad/Anritsu and Furuno radars.
3. The optional NI300X NMEA Interface (expansion) Unit with 4 additional
NMEA input/output ports.
The NMEA output may also drive IS15 instruments directly.

NMEA In
This connection will provide speed and depth input to the autopilot. If an
IS15 Wind Transducer is connected to the system, wind information will
also be transferred to the autopilot.
The connection is made by a Roblink cable from the instrument NMEA
socket (4) to the J3xx Junction Unit Main Board, Terminal RX1+ and RX1-.
See Figure 4-25.
NMEA Out
This will provide the instrument system with heading data.
The connection is made by a Roblink cable from J3xx Junction Unit Main

4.28 NI300X NMEA Interface Unit
The NI300X is normally installed inside a console or locker close to Nav
receivers, radar and instruments to keep cables short. The unit does not have
controls that need to be operated during installation or use, but you should be
able to take the lid off for inspections, to view LED indication of received
signals. It should be installed with the cable inlet and the Robnet connectors
facing down. The NI300X is designed to operate in a location that provides
ambient temperatures below +55° C (+130° F). It is fastened to the
panel/bulkhead by the external mounting brackets.
Note ! The NI300X is not weatherproof, and must be installed in a dry location!
The NI300X NMEA Interface (expansion) Unit is designed to handle
installations where more NMEA lines have to be tied into the system. Four
NMEA ports are available. An additional output data-port with
DATA/CLOCK signal is capable of generating heading data in the format
used by some radar displays made by Simrad/Anritsu and Furuno. This
feature is thus added to the system if a J3000X Junction Unit is installed
(J3000X has no radar Clock/Data output as compared to J300X and J300X-
40).
Configuration for Simrad/Anritsu or Furuno is selected in the Installation
Setup Menu.
12V out is for driving (max. 3) IS15 instruments (max 250mA load).

4.32 Software Setup Procedure
Description of Installation Settings
The design of the AP35 includes advanced features that have simplified the
installation and setup of an autopilot. The principle advantage is that manual
adjustments that needed to be done on previous models are no longer
necessary with the AP35.
Note ! The installation settings must be performed as part of the installation of the
AP35 system. Failure to correctly set the values in the installation settings
may prohibit the AP35 from functioning properly!
The Installation Settings are grouped into the following functional
categories:
• Language: Selects language used for display information
• Dockside Settings: Sets values of items to be set prior to seatrials
• Interface Setup: Sets the identification of navigation and optional
equipment connected to the AP35 system
• Seatrial Settings: Determines automatic calibrations and steering
parameters
• View Parameters Permits viewing, setting, or changing steering
parameters
Each group is designed to focus on specific functions related to an
installation activity, and enable quick access when changes need to be made.
Some important points regarding the installation settings values:
• When the AP35 is delivered new from the factory, (AND ANY TIME
AFTER A MASTER RESET OF MEMORIES HAS BEEN
PERFORMED) the Installation Settings are all reset to preset (default)
values. The warning message "Installation Setup Required" will appear at
turn on and if an attempt is made to access the AUTO or NAV modes.
• The Dockside, Interface and Seatrial settings can only be accessed when
the system is in STBY mode.
• The values that are selected (also referred to as "PARAMETERS") from
within the Installation Settings Menu, are stored in the memory of the
AP35 system. No specific action is required to "SAVE" the selected
values. Once the value is changed, it is stored until the next time the
menu item is selected and changed.
• The Installation Settings are considered global, enabling values to be
available to all control units in the system.
• The values in the Seatrial Settings are dependent on successful
completion of the Dockside Settings.
Before attempting to turn on the AP35 and perform an Installation Setup, the
hardware installation and electrical installation must be completed in
accordance with the installation instructions.
Simrad AP35 Autopilot
72 22083083H
Installation Settings Menu
The Installation Settings Menu (ISM) is presented on the autopilot display
by pressing and holding the NAV/SETUP pushbutton for 5 seconds.
Note ! The INSTALLATION SETTINGS MENU is different from the USER SETUP
MENU . Refer to flow diagram on the next page for a pictorial view of
Installation Settings Menu .
There are several actions that you can do once you have accessed the ISM:
• Answer YES to the question by rotating the course dial clockwise
• Proceed to the next item in the menu by pressing the STBD pushbutton.
(Proceeding to the next item when presented with a question is the same
as answering NO to the question.)
• Proceed back to the previous item in the menu by pressing the PORT
button
• Change the selected item shown rotating the course dial
• Leave the ISM by selecting STBY, AUTO, WORK or NAV.
On new installations, and whenever a control unit, junction unit, or software
is replaced in an AP35 system, it is recommended that a MASTER RESET
be performed as described in the ISM prior to proceeding with the setup
procedure.
When using the ISM refer to diagram "Installation settings Menu Flow
Chart" on next page.
Language selection
The AP35 can present the display in eight different languages:
• English, Norsk, Francais, Espanol, Italiano, Nederlands, Svenska and
Deutsch.
To access the language selection in the ISM:
1. Turn on the equipment and wait approx. 5 seconds.
2. Press the NAV/setup button for about 5 seconds until the display is
changed to:

Automatic Rudder Test
Note ! Move the rudder manually to midship position before starting the test. It is
important also that if the boat uses power assist steering, that the engine or
electric motor used to enable the power assist steering be turned on prior to
this test. Stand CLEAR of the wheel and do not attempt to take manual
control of the wheel during this test!
Activate the automatic rudder test by turning the course selector clockwise.

Transition Speed
INSTALLATION
Transition
speed: 00 kn
The transition speed is the speed where the AP35 will automatically change
the steering parameter set from the HI speed to LO speed parameters, or vice
versa.
The default setting of transition speed is zero, which requires that steering
parameter selection be done manually. If a GPS, Loran, or external speed log
input (from IS15 or other instrument systems) is connected, it is
recommended to set the transition speed to a value greater than 0, to enable
the automatic speed selection feature in the AP35.
It is recommended that you set the transition speed to a speed that represents
the speed where the hull begins to plane, or where you would manually
change the parameters from HI to LO.
The speed used for the automatic transition is obtained as follows:
1. Data from the source set in the interface setup for the INSTR channel. If
this is a valid source of VHW (speed through the water) data, then this
data is used for determination of when to change parameter sets.
2. If VHW data is not available from the INSTR channel or if the INSTR
channel is not cond, the AP35 system will use the speed data obtained
from the VTG (speed over ground) sentence received from the currently
selected POS source.

If no speed data is available on either the INSTR channel (VHW) or the POS
source (VTG), manual speed selection is required. The AP35 will always
default to the HI speed steering parameters when the system is first turned
on, and with speed data failure.
If manual speed selection occurs (the user manually selects HI or LO
parameters), the manual parameter set will remain in effect until the AUTO
mode is re-selected.
Rotate the course dial clockwise until the transition speed is set to the
desired value in knots.
Proceed to next menu item by pressing STBD [>] button.
Autotrim WORK
The Autotrim parameter can be
permanently switched off in the WORK
mode. If the Autotrim is set to ON, it is
automatically switched off when the speed
is below 2 kts. (Ref. page 23). Rotate the
course dial to select between ON and OFF.
Proceed to next menu item by pressing STBD [>] button.
Initial Rudder
When Actual is selected, the autopilot will
use the current
rudder position as midship
reference (bumpless transfer) when
switching from Stby to Auto or Nav. (or
Dodge).
When Midship is selected the autopilot will
use zero degrees as midship reference.
Hence, the rudder will always move to
midship when switching from Stby (or
Dodge) to Auto or Nav mode.
Master reset

Note ! A Master Reset is part of the final test at factory and will reset the memories
to factory settings. Unless you need to clear all stored values during the
installation setup procedure, you should not perform a Master Reset.
If Master Reset is performed, Dockside settings must be done again, as well
as Interface- and Seatrial settings. If an RFC35 or RC25 is connected, the
compass must
be re-calibrated!
Installation

The Master Reset needs a double confirmation to prevent an unwanted reset.
To perform a Master Reset, rotate the course selector clockwise and observe
the display; then rotate the course selector counter clockwise.
Interface Settings
The AP35 system provides a totally flexible approach to the input of data
from heading sensors and other peripheral equipment. Identification of the
type of equipment connected to the AP35 system is performed in the
Interface Setup Menu.
If your system includes connection of external equipment to the NMEA0183
data ports in Junction Unit or NI300X, or if the CI300X is installed with
optional compass units or an optional analog wind vane unit, they must be
configured under this menu. This procedure allows you to assign an
abbreviated name to identify the type of equipment that is connected to each
of the available hardware ports in the AP35 system.

Compass Offset
The compass OFFSET feature allows you to correct for a constant compass
heading offset, that may be present as a result of the RFC35 being installed
with a lubber line offset or a fixed offset remains after the calibration
procedure has been completed. The value of compass offset is specific to the
heading sensor that is selected at the time the offset is entered. (For multiple
heading sensor offset procedure, choose Compass in User Setup. Refer to
User Set-up Menu, page 27. Then re-enter Installation, Compass Offset, and
set the required offset for chosen compass, or refer to separate CI300X
manual).

Note ! If an OFFSET still exists after having accounted for the mechanical offset,
one of the following problems may still exist:
• The heading reference that you are comparing the RFC35 is not accurate.
• The automatic calibration obtained by the RFC35 is not correct, and may
be due to a large magnetic influence near the RFC35. (A relocation may
be needed.)
Caution ! Do not compare with GPS’ COG since your GPS is showing course and
not heading.
Proceed to the AUTOTUNE function by pressing the STBD [>] button, or
return to STBY mode.
Automatic tuning
AUTOTUNE is a dynamic function that enables the AP35 system to
automatically set up the two main steering parameters (Rudder and Counter
Rudder) for the boat. The scaling factors of the parameters are also set
automatically as a function of the boat type selection performed in the
Dockside Settings menu.
Note ! Autotune is an optional procedure that is not required for the AP35 to
function. The AP35 is preset with steering parameters that should steer most
boats in the 30 - 50 foot range and Autotune may not be required if the
preset parameters steer your boat acceptably.
Recommended speed during Autotune varies with type of boat, but should
not exceed 10 knots. Autotune should not
be performed at planing speed!
For displacement boats use a speed that is about half the normal cruising
speed (i.e. if cruising speed is about 10 knots, do the Autotune at about 5
knots). The parameter values calculated during this Autotune becomes the
LO speed parameters. The HI speed parameters is automatically set to 66%
of the LO speed parameters. It is recommended that the Autotune be done in
an East or West direction if possible, as these will yield the best balanced
parameters.
WARNING ! The Autotune function will take control of the boat and perform a
number of S-turns. It must always be performed in open waters with
sufficient safe distance to other traffic. The Autotune function may
take from 1 to 2 minutes to complete.

Note ! The values in the table are factory set and listed for information only. After
having performed the Autotune, the values may differ from those listed in the

the Autotune prior to making any adjustments.
The two most important parameters that determine the performance of the
automatic steering are Rudder and Counter Rudder.
Rudder sets the rudder gain which is the ratio between the commanded
angle and the heading error ( P-factor).
• Too little Rudder and the autopilot fails to keep a steady course.
• Too much Rudder gives unstable steering and reduces speed.
• Low speed requires more rudder than high speed.

Counter Rudder is the parameter that counteracts the effect of the boats
turn rate and inertia. For a short time period it is superimposed on the normal
rudder response as provided by the Rudder parameter. It may sometimes
appear as if it tends to make the rudder move to the wrong side (counter
rudder).
The best way of checking the value of the Counter Rudder setting is when
making turns. The s illustrates the effects off various Counter Rudder
settings.
Autotrim standard value is 40 which should work well on most boats.
When the vessel has a constant heading error, due to external forces such as
wind and current, the AUTOTRIM function takes account for this by
building up a constant rudder offset. The time factor when the AUTOTRIM
parameter is adjusted, is the time it takes to build up the rudder offset.
Rudder Limit determines the maximum rudder movement in degrees from
midship position. It should be kept at 20 degrees unless there is a need for
more rudder when performing dockside manoeuvres.
Caution ! In no event should the Rudder Limit be set to a value higher than the
actual maximum rudder angle.
4.34 Final sea trial
After having completed all settings in the Installation Settings Menu, take
the boat out and perform a final sea trial in open waters with sufficient
distance to other traffic.
• Steer the boat on all cardinal headings in AUTO mode.
• Start with low and medium speeds to get familiar with the response from
the AP35.
• Try the effect of LO and HI speed settings.
• If the hardware for automatic HI/LO speed selection is connected and
configured, verify that the HI/LO transition is occurring, and the HI/LO
parameters are changing after the transition speed is crossed (by more
than 1 Knot higher or lower speed).
• Try the Dodge function, the U-turn and the C-turn.

• If a Non-Follow Up lever (or handheld remote) is connected, test the
mode switching and verify Port and Stbd steering commands of the lever.
• Set waypoints into each navigator connected to the system, and verify
that the AP35 steers in NAV mode for each NAV source.
• Provide the owner with user training.
4.35 Providing user training
The user should be instructed in the "basic" operational functions, such as:
• Turning the system on and off
• Explain how to change modes (explain briefly what takes place in the
different modes).
• Regaining manual control from any mode. Point out in what modes the
helm is engaged by the autopilot (bypass/clutch).
• How to take command at an "inactive" station if applicable.
• Lock mode and how to lock/unlock and how to shut the system down
from a locked control unit if applicable.
• Show NFU and FU steering and show the difference.
• Review how to use a NFU controller if connected.
• Course change by rotary knob and buttons.
• Go through the user SETUP menu and show how to (and why) change
the settings.
• Also include Nav. source, Pos. source and Compass sensor selection if
applicable.
• Show the owner where the compass (or compasses) is mounted and
instruct him to keep magnetic items away.
• Show where the Mains circuit breaker is.

5 MAINTENANCE
5.1 Control unit
The AP35 Control Unit will under normal use require little maintenance as
the cases are made from seawater resistant aluminium and has a polyester
coating to withstand the rigours of an exposed cockpit.
If the unit requires any form of cleaning, use fresh water and a mild soap
solution (not a detergent). It is important to avoid using chemical cleaners
and hydrocarbons such as diesel, petrol etc.
Make sure that all open ROBNET connectors are fitted with a protection
cap.
It is advisable at the start of each season to check all connections to the
control unit head and cover with Vaseline or WD40. If the Control unit is not
removed from the boat, it should be covered.
5.2 Junction Unit
No special maintenance is required. It is advisable, however, at the start of
each season to make a visual inspection of the internal and check all
connections.
5.3 Rudder Feedback
Make a visual inspection at 2-3 month intervals and at the start of each
season. Apply some grease at the transmission link ball joints when required.
5.4 Compass
If the compass is exposed to the weather, make a visual inspection at 2-3
months intervals, and at the start of each season.
5.5 Drive unit
Refer to the drive unit manual for maintenance instructions.

described on page 78.
Modification on AP35 PCB
Refer to our Technical bulletin no. 10/97. The modification is valid from
PCB S/N 913 and onwards. Modified PCBs are not compatible with former
S/N code ---A70 of the control unit. All AP35 Control Units from S/N
905A71 onwards have got modified PCBs, and accordingly they have got
the new A71 code.
It is important to notice that PCBs with revision D are not compatible with
PCBs having revision C or earlier. As a consequence the following must be
observed:
1. Control units with S/N code A71 must have PCBs with revision D.
2. Control units with S/N code A70 must have PCBs with revision C or
earlier.

6 TROUBLE SHOOTING
An autopilot is a complex system and the performance is dependent of a
proper installation and a successful sea trial.
In the event of a failure, you will be helped by the AP35 software which
contains several test features that will assist you in isolating a probable fault.
Audible and visual alarms are given in the event a fault is detected.
The audible alarm is reset by pressing any button (e.g. by changing mode
from AUTO to STBY). The visual alarm will remain and alternate with the
operating display until the fault has been rectified. Refer to the table below
for hints and try to solve the problem yourself, or consult your nearest
Simrad dealer for assistance.
Perform the repair action in the listed order.

The NMEA test menu is accessed from the User Set Up Menu (page 27). It
provides you with status information of the different NMEA messages used
in the system.
Decoding
The incoming signals are decoded
according to a built in priority table.
Cross Track and bearing information is
taken from the NMEA messages with
highest priority.
One of the following codes will be
displayed:
--- No data or no NMEA sentence
containing the data needed at the input port.
OK Valid data found
INV Message with invalid information.
FRM Message has format failure such as
a) Incorrect check sum
b) Wrong contents in datafield(s)
Check status and set up of data source.
NMEA signal monitor
Close to the NMEA terminals in the
junction unit you will find a green LED. A
flickering LED indicates that a NMEA
signal is received. It does not, however,
qualify the contents of the message.
