Instruction Manual
This manual is intended as a reference guide for operation
of the Simrad AP51 Remote Control.
Great care has been taken to simplify the set-up and
operation of the AP51; however, an autopilot is a complex
electronic system. It is affected by sea conditions, speed of
the vessel, and vessel hull shape and size.

1 GENERAL INFORMATION
1.1 Introduction
Congratulations on the purchase of your new Simrad AP50
autopilot system and thank you for selecting what we feel is one
of the most advanced autopilot system available on the market
today.
Today, Simrad manufactures a complete range of autopilots for
all types of vessels, from leisure boats to advanced steering
systems for merchant marine vessels. Our factory for these
products Simrad Egersund AS, is located in Egersund on the
southwest 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 AP50 autopilot system from Simrad represents yet another
step forward in autopilot technology with the intent of providing
small fishing boats and work boats up to 200 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 AP50 autopilot system is the single "intelligent"
junction unit that communicates with all other system modules
on a 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 AP50 system to
be easily expanded at any time. Any unit that is connected to the
autopilot system via Robnet is called a Robnet Unit.
The AP50 system is produced and tested in accordance with the
European Marine Equipment Directive 96/98. This means that
the AP50 complies with the highest level of tests for nonmilitary marine electronic navigation equipment existing today.
The Marine Equipment Directive 96/98/EC (MED), as amended
by 98/95/EC for ships flying EU or EFTA flags, applies to all
new ships, to existing ships not previously carrying such
equipment, and to ships having their equipment replaced.
This means that all system components covered by annex A1
must be type-approved accordingly and must carry the
Wheelmark, which is a symbol of conformity with the Marine
Equipment Directive.

Simrad AP51 Remote Control
While the AP50 system may be installed on vessels not needing
to comply with the Marine Equipment Directive, those requiring
compliance must have one AP50 Control Unit set-up as “master
unit” in order for the installation to be approved. Simrad has no
responsibility for the incorrect installation or use of the AP50
autopilot, so it is essential for the person in charge of the
installation to be familiar with the relevant requirements as well
as with the contents of the AP50 manual. This manual covers
correct use of AP51 Remote Control.
The purpose of the Marine Equipment Directive is to enhance
safety at sea and to prevent marine pollution through the
uniform application of the relevant international instruments
relating to equipment listed in Annex A1.
As there are many interfacing requirements in the
standards/codes, integrated systems and integrated certification
lead to more efficient and effective management of safety,
environmental issues, and quality.
The Marine Equipment Directive also constitutes a part of the
International Safety Management (ISM) Code. The ISM Code
was included as a new chapter (IX) of SOLAS in 1994, and is
mandatory for: passenger ships not later than 1st of July, 1998;
oil tankers; chemical tankers; gas carriers; bulk carriers and
cargo high speed craft of 500 gross tonnage and upwards not
later than 1st of July, 1998; and other cargo ships and mobile
offshore drilling units of 500 gross tonnage and upwards not
later than 1st of July, 2002.
It is required that both the shipping company and ships shall be
certified by the Administration (the government of the state
whose flag the ship is entitled to fly), by an organization
recognized by the Administration, or by the government of the
country acting on behalf of the Administration.
1.2 How to Use This Manual
This manual is intended as a reference guide for operating the
Simrad AP51 Remote Control. Great care has been taken to
simplify the set-up and operation of the AP51; however, an

Simrad AP51 Remote Control
The AP51 Remote Control shown on page 9 can only operate as
a remote control in an AP50 autopilot system or in a multistation
system. In a multistation system, command can easily be
transferred from one unit to another and units not in control will
display "Inactive".
The autopilot system may also be disabled from the ships’
steering system with an external switch. This will totally
disengage the autopilot system from the ships’ main/emergency
steering system and the units will display “DISENGAGED”.
The AP51 is capable of the following primary steering modes
with each mode having a dedicated push button: STANDBY
(FU-NFU), AUTO, NAV and DODGE. AUTO and NAV modes
also have a sub-mode that is accessed by a long press on the
AUTO or NAV button respectively. The AUTO-WORK and
NAV-WORK sub-modes are used under operational conditions
different from those normally found when a vessel is in transit
on a preset course (e.g. trawling, towing, trolling on one engine,
slow speed, using a thruster, etc.).
Each of the mode buttons is clearly identified with the primary
function in large text and a secondary function listed in smaller
text. Each button provides you with the ability to access a
primary display, a secondary display, and/or multiple function
displays.
A group of user-adjustable settings belonging to the selected
mode are provided in the AP51 User Set-up Menu (see page 27).
The settings allows adjustment of display visibility, selection of
heading sensors, navigation and position sources, and the ability
to select between automatically or manually adjustable sea state
filter.
Alarms are presented in plain text to alert you to both system
and external data failure conditions. Alarms include both audible
and visual presentations. The alarms are listed on page 41
2.2 ON/OFF - Standby Mode (STBY)

WORK
The AUTO mode is used to make the AP51 steer the vessel
automatically on a set heading. AUTO mode is always available
from any mode or function within the AP51 by a single push of
the AUTO button. When AUTO mode is selected, the AP51
automatically selects the current vessel heading as the set
heading and the rudder will move to midship position.
In AUTO mode, the AP51 issues rudder commands to keep the
boat on the set heading. The boat heading is provided by the
steering compass.
The AP51 will keep the boat on the set heading until a new
mode is selected or a new heading is set with either the course
knob, the
(PORT) or
(STBD) buttons, or by pushing the
AUTO button again. One revolution of the knob equals a 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.

2.6 Thruster Steering
If the vessel is equipped with a thruster, it can be connected to
the AP50 system. The vessel can then be controlled by rudder,
thruster, or both rudder and thruster (Steering function) .
After connecting a thruster to the autopilot system (see the TI50
manual) the thruster type must be selected under the Installation
Dockside menu (refer to the AP50 manual).
A thruster icon below the mode index indicates that a thruster is
connected to the system.
Now you can select one of three control functions from the User
Set-up Menu, Steering function:
• Rudder: The rudder is used to maintain the heading (always
in AUTO mode and NAV mode).
• Thruster: The thruster is used to maintain the heading (only
in AUTO-WORK, NAV-WORK, Follow-up, and NonFollow-up steering modes).
• Rudder and Thruster: Both rudder and thruster are used to
maintain the heading (only in AUTO-WORK mode, NAVWORK mode, Follow-up and Non-Follow-up steering
modes).

Caution
When operating an On/Off thruster it is important to note that
most electrical thrusters have a built in thermal cut-off switch
that will shut off the electromotor if it is overheating and reengage it when it has cooled down. The water temperature also
affects the running time. The On/Off thruster may only run for
a few minutes, and its total running time for a longer period
should be limited by increasing the thruster sensitivity value
(refer to the AP50 manual).
2.7 Navigating with the AP51
The AP51 has the capability to use steering information from an
external navigator (GPS/Chart plotter or ECS) to direct the boat
to one specific waypoint location or through a series of
waypoints. In the NAV mode, the AP51 uses the heading sensor
as its heading source for course keeping. The steering and speed
information received from the external navigator alters the set
course to direct the AP51 to the destination waypoint.
Note !
Navigational steering must only be used in open waters. By
selecting the NAV mode, the AP51 is set for automatic steering
on the current set course towards a destination waypoint.
To obtain satisfactory navigation steering, the following
conditions must be fulfilled prior to entering the NAV mode:
• The autosteering must be tested and determined satisfactory
• The navigation receiver must be operating and the navigation
system (GPS/Chart plotter or ECS) 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 AP51 User Set-up menu must be
set for the navigator that contains the current waypoint
The AP51 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]).

If you use a GPS/Chart plotter, AP51 will display an alert screen
with the proposed new course information, when you arrive at
the waypoint arrival circle. 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-WORK button
or turning the course knob after the alert screen is displayed. If
an external alarm unit (optional) is connected to the AP50
system, an alarm is given after 5 seconds. If no verification is
received, the AP51 will continue on the current set course in
NAV mode.
Regain manual steering at any time by pressing the

If “END ROUTE” is used as final WP-name, an “End of route”
warning will be given on the active control unit when arriving at
the final WP.
Note !
If the AP50 system is connected to a navigation receiver that
does not transmit a message with the bearing to the next
waypoint, it will pick a Cross Track Error message and steer on
Cross Track Error only. In that case you have to revert to AUTO
mode at each waypoint and manually change the set course to
equal the bearing to the next waypoint and then select NAV
mode again.
Setting the waypoint arrival circle
For route navigation it is recommended to use automatic
waypoint shift/change at a set waypoint arrival circle.
The arrival circle should be adjusted according to boat speed.
The higher speed, the wider circle. The intention is to make the
autopilot start the heading change in due time to make a smooth
turn onto the next leg.

NAV
Press NAV to accept the first waypoint as the location to steer
towards. The autopilot turns the boat onto the new course while
the display flashes “TURNING”.
SETUP
Accepting the first waypoint as the location to steer towards you
also accept the autopilot to automatically steer the boat through
the route of waypoints. When the autopilot changes the course at
each waypoint, the display flashes “TURNING”.
If you wish to confirm the new heading at each waypoint, GPS
has to be selected as NAV source.
A route consists of a series of waypoints joined together with
straight legs. Each waypoint in a route, except the first and the
last, has an associated turn radius defined. This turn radius will
allow the ship to turn before the waypoint is reached.
Caution
20221016C
If an ECS is selected as a navigator, the course change
verification is waved. This is done so the AP50 is capable of
following a route in which the radius of the course change is
pre-set in the chart system. Users navigating in this mode must
use extra caution.

Robnet network cables
As most Robnet units have 2 Robnet connectors, they can be
used 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 lengths and they
contain a 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.
Additional extension cable (10 m) with a male and a female
connector is available from Simrad (part no. 20192266).
When installing a system, try to minimize the total Robnet cable
length by connecting all Robnet units to the nearest available
Robnet connector.
For total length of Robnet cable refer to table in the AP50
manual.

Installation
AP51 in a Wheelmark System
In a Wheelmark system, only the Master Unit may turn the
system off. To ensure that the system cannot be switched on or
off from the AP51 Remote Control Unit, the yellow wire in the
AP51 cable must be cut or not connected. Open the Robnet
connector (see Figure 4-3). Remove pin 3 (yellow wire) and cut
it off at the end of the wire. Insulate the wire and push it back in
the pin 3 slot. Reassemble the Robnet connector.
Note !
This must be done to enable a valid installation according to the
Marine Directive (Wheelmark).
JP21 Jack Point Installation
The JP21 Jack Point can be used in conjunction with the AP51
Remote Control.
It provides a quick and simple means of connection and
disconnection of the AP51 at different locations on the boat.
The JP21 includes a watertight connector cover that must be
installed as shown below. A 32 mm (1.26 inch diameter) hole
must be drilled for flush installation, along with 3 small screw
holes. As indicated, a watertight sealant must be applied to the
mating surfaces of the JP21 and the mounting panel. Apply a
thin layer of Vaseline to the O-ring seal.

In the event of an autopilot failure, the AP50’s numerous test
features that will assist you in isolating a probable fault.
Audible and visual alarm is provided for every fault being
detected.
The audible alarm is reset by pressing any button (e.g. by
changing mode from AUTO to STANDBY). All visual alarms
will remain and alternate with the operating display until the
fault has been rectified. If an external alarm buzzer is installed
(refer to the AP50 Manual) the external alarm will be given 5
sec. after the internal. Refer to the table below for hints to try to
solve the problem yourself. You may also consult your nearest
Simrad dealer for assistance, if required.
Perform any repair actions in the listed sequence.
Note !
‘Compass difference’, ‘Vessel off course’, and ‘Rudder limit’
warnings are automatically reset when the error is rectified.

Apparent wind – The speed and direction from which the wind
appears to blow with reference to the bow when the boat is
moving (also called relative wind).
Arrival alarm – An alarm signal issued by a voyage-tracking
unit that indicates arrival at or at a predetermined distance from
a waypoint. (see arrival circle).
Arrival circle – An artificial boundary placed around the
destination waypoint of the present navigation leg, the entering
of which will signal an arrival alarm.
Arrival perpendicular – Crossing of the line which is
perpendicular to the course line and which passes through the
destination waypoint.
Bearing – The horizontal direction of one terrestrial point from
another, expressed as the angular distance from a reference
direction, usually measured from 000° at the reference direction
clockwise through 359°.
BPW – Bearing position to waypoint – Bearing to a specified
waypoint from present position.
BWW – Bearing waypoint to waypoint - Bearing angle of the
line between the “TO” and the “FROM” waypoint, calculated at
the “FROM” waypoint for any two arbitrary waypoints.
COG - Course Over Ground - The actual direction of progress
of a vessel with respect to the surface of the earth. The vessels
heading may differ from the course over ground due to the
effects of wind, tide, currents.
ECS – Electronic Chart System
For advanced navigation steering with preset radius in routes of
waypoints.
ECDIS – Electronic Chart Display Information System.
Type approved ECS system according to the ECDIS regulations.
GPS - Global Positioning System - This system consists of 18
satellites plus 3 spares in fixed orbits, circling the earth at an
altitude of approximately 20,200 km. The system will provide
the user with 24 hour a day all weather position coverage, with
an accuracy of 15 to 100 meters.
Great circle route – A course that is the shortest distance
between two points, following a great circle

Glossary
Heading – The horizontal direction in which a ship actually
points or heads at any instant, expressed in angular units from a
reference direction, usually from 000° at the reference direction
clockwise through 359°.
IMO MSC(64)67 – (International Maritime Organization)
Performance standards for heading control system.
ISO 11674:2000(E) – (International Organization for
Standardization) Specifies the structure, performance, inspection
and testing of heading control systems.
Loran C - A complex radio navigation network developed by
the US coast guard, to assist a navigator in determining his
precise location. The acronym, Loran C, stands for Long Range
Navigation. It is an all weather 24 hour a day electronic system
of shore based radio transmitters.
Magnetic bearing – Bearing relative to magnetic north;
compass bearing corrected for deviation.
Magnetic deviation – Compass error; the difference between
the reading of a compass and the actual magnetic course or
bearing due to errors in the compass reading.
Magnetic heading – heading relative to magnetic north.
Magnetic variation - A magnetic compass points to the
magnetic north pole. The difference between this direction and
true north is the magnetic variation. The amount and direction of
this variation is dependent upon where on the earth you are
located.
NMEA 0183 - A format (language) designed to permit
communication between various types of marine electronic
equipment. In essence, this is a two-wire shielded, serial data
link, permitting one device to talk while other devices listen.
Numerous different sentences are available, permitting
communication between various different devices.
Rhumb line – A line that passes through all meridians at the
same angle. When drawn on a Mercator chart, the rhumb line is
a straight line. However, the Mercator chart is a distortion of a
round globe on a flat surface, so the rhumb line will be a longer
course than a great circle route.
Route - A stored sequence of waypoints. These waypoints will
be listed in the order in which you desire to follow them.
SOG - Speed over ground is the actual speed of the vessel
relative to the ocean floor.
True bearing – Bearing relative to true north; compass bearing
corrected for compass error.
20221016C
49
Glossary
True heading – Heading relative to true north (the meridian)
VDR – Voyage Data Recorder. Recording and storing all
information that can be relevant for reconstructing accidents,
such as time, date, position, speed, heading, depth, video,
communication, etc. Performance requirements are specified in
the IMO A.861(20), the EU directive 1999/35/EC and
IEC61996.
Waypoint - A discrete point, stored in a navigator, located on
the surface of the earth. Normally this point will be identified by
Lat/Lon coordinates although in some systems it may be shown
by T.D.'s.
XTE - Cross Track Error - Used to identify a vessels position
relative to a straight line drawn between two waypoints. The
amount the vessel is off to the left or to the right of this line is
known as the track.
