Mounting location

Choose the mounting locations carefully before you drill or cut. The display should be
mounted so that the operator can easily use the controls and clearly see the display screen.
Be sure to leave a direct path for all of the cables. Simrad displays are high-contrast and
anti-reective, and are viewable in direct sunlight, but for best results install the display out
of direct sunlight. The chosen location should have minimal glare from windows or bright
objects.

The enclosure that the display is mounted in should be dry and well ventilated. The ventila­tion of the space behind the unit should be enough to prevent excessive heat build up as a
combined result of radiated heat o the heat sink, and sunlight heating of the enclosure. In
very small enclosures, also subject to heating from the sun, it may be required to t forced
cooling.

Ensure that any holes cut are in a safe position and will not weaken the boat’s structure. If in
doubt, consult a qualied boat builder.

Before cutting a hole in a panel, make sure that there are no hidden electrical wires or other
parts behind the panel.

Do not mount any part where it can be used as a hand hold, where it might be submerged, or
where it will interfere with the operation, launching or retrieving of the boat.

12 |

Planning the installation | NSS Installation Manual

If bracket mounting the display choose an area where the display will not be subjected to
excessive vibration.

The mounting location will aect the internal GPS receiver. Ensure you test the unit in its
intended location to ensure satisfactory reception. An external GPS source may be added to
overcome poor reception areas.

Leave sucient clearance space to connect all relevant cables.

For overall width and height requirements, please see the dimensions section on page 52.

¼ Note: The bracket kit is an optional accessory that needs to be ordered seperately.

!Warning: Poor ventilation combined with a small mounting enclosure could poten-

tially cause the display to overheat - B&G displays are designed to operate in temperatures
from -15° C to +55° C (+5° F to +131° F).

Ensure unit is not installed too close to devices that may emit harmful interference, or devices
that may be sensitive to any electromagnetic eld disruption caused by the unit. Typical
minimum ‘safe’ distances are indicated below.

Connecting power

Power connection (basic)

The NSS display can be powered by either 12 V
or 24 V DC. Displays are protected against reverse
polarity, under voltage and over voltage.

The supplied power cable has a four core cable
used for:

• power into the system (Red and Black wires)

• controlling power state of the display or power

state of other displays and devices (Yellow wire)

• connecting to an external alarm (Blue wire)

Connect Red to (+) DC using a 5 amp fuse for
NSS12, and a 3 amp fuse for NSS7 and NSS8.
Connect Black to (-) DC. The display can be
powered on and o using the power button.

Power Control (yellow wire)

Planning is required how you want to be able to turn on and o the NSS an connected com­patible devices.

The yellow (Power Control) wire on the NSS power cable can either be an input that will turn
on the display when power is applied, or an output that turns on other devices when the
display is powered on. It can be congured at the installation stage to control the power state
of displays and compatible devices. When commissioning the system, displays can be set to
be a Power Control Slave or Power Control Master.

Power Control conguration options of the NSS are:-

• use the Power button to turn on the display only: Yellow wire not connected

• display to turn on when power is applied to the display: Common red and yellow wires

• use the Power button to turn on the display and other displays and or compatible devices

such as Broadband Radar: Yellow wire connected to a Power Control Bus. (Set one or more
displays to be a Power Control Master)

External GPS | NSS Installation Manual

External GPS

Mounting location

Depending on vessel design and materials, certain mounting locations chosen for the NSS
may not oer adequate GPS satellite signal reception using the internal receiver. An external
GPS source such as the GS15 can be used to overcome this, by allowing remote installa­tion in a location that has an unobscured view of the sky. An NMEA 2000 expansion kit may
be required to connect the GPS antenna to the NSS, if no other network cabling is already
installed.

Refer to “Device connection” on page 31 for further details on connecting to the network.

Echosounder setup

Select echosounder source

Choose the Echosounder source in the Echo Settings . MENU > MENU > ECHO.

This can be selected to be the echosounder built in to the display (NSS7 and NSS8 only), or an
external sounder module such as the BSM-1.

Deselecting the Network Echosounder option, limits source selection to internal sonar only.

Depth oset

This is a value that can be entered on the Echo Installation page to make depth readings
relate to any point from the water surface, to the deepest point of the vessel.

Below are some typical ways in which the oset is used:

A) For Depth below Keel: Set the distance from transducer to the keel.

Enter a negative value, e.g.

B) For Depth Below Transducer: no oset required.

C) For Depth Below Surface (waterline): Set the distance from transducer to the surface:

Enter a positive value., e.g.

A B C

Echosounder software version

For external sounder modules, the software version is displayed under Sonar installation. To
upgrade Sonar software, see page 49

Water speed calibration (Echosounder transducer)

Water speed calibration is used to adjust the speed value from the paddle wheel to match the
actual boat speed through the water. Actual speed can be determined from GPS speed over
ground (SOG) or by timing the boat over a known distance. Water speed calibration should be
performed in calm conditions, with minimal wind and current movement.

Select Auto correct to match water speed to ground speed (SOG).

Manual calculation. Increase this value above 100% if the paddle wheel is under reading, and
decrease this value if it is overreading, e.g. if the average water speed reads 8.5 knots and SOG

ment, divide the SOG by the paddlewheel speed, and multiply the product by 100.

Calibration range: 50-100%. Default is 100%.

Water speed averaging (echosounder transducer)

Averages water speed by measuring your speed at a selected interval of time. Water speed
intervals range from one to thirty seconds, e.g. If you select ve seconds, your displayed water
speed will be based on averaging over 5 seconds of sampling.

Calibration range: 1-30 seconds. Default is 1 second.

Water temperature calibration (echosounder transducer)

Temperature calibration is used to adjust the water temperature value from the echosounder
transducer to match the data from another temperature sensor. It may be required to correct
for localised inuences to the measured temperature.

Calibration range: -9.9° - +9.9°. Default is 0°.

¼ Note: Water temperature calibration only appears if the transducer is temperature capable.

Check transducer type selection if this option should be available.

Transducer type

Transducer type is used for selecting the transducer model connected to the echosounder
module. In some transducers with built-in temperature sensors, the temperature reading may
be inaccurate if the wrong transducer is selected from the transducer type menu.

RADAR | NSS Installation Manual

Radar setup

Setup and conguration of the Broadband radar has been simplied compared to traditional
pulse radars. There is no zero range (time delay), no warm up time, and no burn-in required..

Radar status

Scanner type

Identies the model of scanner connected to the network.

Software version

Check to make sure you have the latest software. check website for the latest version.

Serial Number

This number should be recorded for support and insurance purposes.

MARPA status

The MARPA status can identify if a heading sensor is on the network and that the radar is
receiving heading information essential for MARPA calculations.

Reset device ID

NSS displays only support one radar on the network. Should a radar be connected, that has
been connected to a dual radar network in the past, it may not be detected by the display
because it has an incorrect Device ID. With the radar connected and power up, select the
Reset Device ID button to resolve this problem.

¼ Note: This procedure must be performed with only one radar on the network.

Adjust bearing alignment

This is to align with the heading marker on the screen with the center line of the vessel, this
will compensate for any slight misalignment of the scanner during installation. Any inaccu­racy will be evident when using MARPA or chart overlay.

Point the boat to be perpendicular to the very end of a breakwater or peninsula. Adjust the
bearing alignment setting, so that the heading marker and land mass intersect.

Adjust antenna height

Set the radar scanner height. The Radar uses this value to calculate the correct STC settings.

Adjust local interference reject

Interference from some onboard sources can interfere with the Broadband radar. One
symptom of this could be a large target on the screen that remains in the same relative
bearing even if the vessel changes direction. Choose from Local interference rejection LOW,
MED or HIGH. Default is LOW

RADAR | NSS Installation Manual

Sidelobe suppression

¼ Note: This control should only be adjusted by experienced radar users. Target loss in harbour

environments may occur if this control is not adjusted correctly.

Occasionally false target returns can occur
adjacent to strong target returns such as
large ships or container ports. This occurs
because not all of the transmitted radar
energy can be focused into a single beam
by the radar antenna, a small amount
energy is transmitted in other directions.
This energy is referred to as sidelobe
energy and occurs in all radar systems. The
returns caused by sidelobes tend to appear
as arcs:

When the radar is mounted where there are metallic objects near the radar, sidelobe energy
increases because the beam focus is degraded. The increased sidelobe returns can be elimi­nated using the Sidelobe Suppression control in the Radar installation menu.

By default this control is set to Auto and normally should not need to be adjusted. However
if there is signicant metallic clutter around the radar, sidelobe suppression may need to be
increased. The control should be adjusted as follows:

1.

Set Radar range to between 1/2 nm to 1 nm and Sidelobe Suppression to Auto.

2. Take the vessel to a location where sidelobe returns are likely to be seen. Typically this would be near a

large ship, container port, or metal bridge

3. Traverse the area until the strongest sidelobe returns are seen.

4. Change Auto sidelobe suppression to OFF then select and adjust the sidelobe suppression control until

the sidelobe returns are just eliminated. You may need to monitor 5-10 radar sweeps to be sure they
have been eliminated.

5. Traverse the area again and readjust if sidelobes returns still occur.

6. Exit the installation menu.

Restore radar to Factory Default

This can be used to revert all user adjustments.

NMEA 0183 | NSS Installation Manual

NMEA 0183

To exchange NME0183 data, the NSS display has a NMEA 0183 serial port, providing both an
input and an output.

The port uses the NMEA 0183 (serial balanced) and RS232 (single ended) standards, and can
be congured in the software for dierent baud rates up to 38,400 baud. NMEA 0183 sen­tences output by the NSS can be individually turned on or o.

Refer to “NMEA 0183 supported sentences” on page 61 for a complete list of sentences.

pin 2.

Talkers and Listeners

Do not connect multiple devices outputing data (Talkers) on to the input (Rx) of the NSS
display. The RS232/RS422 standards are not intended for this type of connection, and data
will be corrupted if more than one device transmits simultaneously. The output however
may drive multiple receivers (Listeners). The number of receivers is nite, and depends on the
receiving hardware. Typically three devices is possible.

Serial communication

This should be set according to correspond with devices connected to the NMEA 0183 input

Baud rate

Baud Rate is set simultaneously for the input and the ouput, it can not be set at a dierent
speed for each. It should be set to match the speed of the device connected to it. Most
NMEA 0183 devices send data at 4800 baud.

¼ Note: AIS transponders typically operate at NMEA 0183-HS (high speed), and will require the

baud rate to be set to 38,400.

NMEA 0183 output

To enable data output, enable the ‘Serial output’ option, and then select which sentences the
NSS needs to transmit to other devices from the ‘Serial output sentences’ list.

NMEA 2000 / SimNet | NSS Installation Manual

NMEA 2000 / SimNet

Device connection

All models of NSS are equiped with an NMEA 2000 port, which allows the receiving and
sharing of a multitude of data from various sources.

Essential network information

• A NMEA 2000 network consists of a linear “backbone” from which “drop cables” connect to

NMEA 2000 devices

• NMEA 2000 cables used for Simrad products are of the ‘micro-c’ style, which is a cable/

connector specication approved for use in NMEA 2000 certied networks. Some Simrad
products use SimNet proprietary connectors, but are compatible via adaptor cables.

• A single drop cable has a maximum length of 6 m (20 ft). The total length of all drop cables

combined should not exceed 78m (256 ft)

• A NMEA 2000 network has a maximum cable length of 100 m (328 ft), between any two

points

• A NMEA 2000 network needs to have a terminator at each end of the backbone. A terminator

can be one of the following:

• a terminator blank plug

• a wind transducer (where the mast cable is one end of the backbone)

Planning and installing a network backbone

The NMEA 2000 backbone needs to run between the locations of all products you want to
install, typically in a bow to stern layout, and be no further than 6 m from a device to be con­nected.

Choose from the following components to make up your NMEA 2000 backbone:

• Micro-C cables: 0.4 m (1.3 ft), 2 m (6,6 ft), 5 m (16.6 ft), and 9 m (29.5 ft) cables

• Micro-C power cables with or without termination

• T-connector. Use at locations where you want to connect a device by drop cable

¼ Note: When using a wind sensor, the mast cable should be connected as the nal length of

cable in one end of the backbone, as the sensor is tted with a termination resistor.

¼ Note: Most NMEA 2000 devices can be connected directly to a Simrad SimNet backbone and

SimNet devices can be connected to a NMEA 2000 network by using adapter cables. (“NMEA
2000 cables” on page 57)

¼ Note: The NSS has a Micro-C NMEA 2000 connector but is fully compatible to work in a Sim-

Net network by using an adapter cable.

¼ Note: IS40 displays have two connectors, and can either be connected inline with the back-

bone, or wired individually o a drop cable. Connecting from device to device is known as
‘daisy chaining’ This network topology is not ocially NMEA 2000 compliant.

11

32 |

NMEA 2000 / SimNet | NSS Installation Manual

Power the network

A NMEA 2000 network requires its own 12 V DC power supply protected by a 5 amp fuse or
breaker. For 24 V systems, use a DC-DC converter to supply 12 V

Connect power at any location in the backbone for smaller systems.

For larger systems introduce power at central point in the backbone to “balance” the voltage
drop of the network.

¼ Note: If joining to an existing NMEA 2000 network or similar CAN bus network that already

has it’s own power supply, do not make another power connection.

¼ Note: Do not connect the NMEA 2000 power cable to the same terminals as the start batter-

ies, Autopilot Computer, Radar, thruster or other high current devices.

The drawing below demonstrates a typical small network. The backbone
is entirely made up of T-piece joiners, which are terminated at each end.

NMEA 2000 / SimNet | NSS Installation Manual

Data bridging

NMEA 0183 to NMEA 2000

All supported NMEA 0183 sentences entering the system are internally bridged (converted) to
NMEA 2000, and output via the NMEA 2000 port for any other devices to use. The only excep­tion is AIS data.

NMEA 2000 to NMEA 0183

The NMEA 0183 sentences shown in the ‘Transmit’ rows of the NMEA 0183 Supported Sen­tences table will be generated if the data is available from a NMEA 2000 data source.

Ethernet to NMEA 2000

Limited data is bridged from the Ethernet echosounder: Speed, depth and temperature are
bridged to NMEA 2000 and NMEA 0183.

Multiple Displays

In multi display setups, each display can be used to convert data from a dierent NMEA 0183
talker, and will be available to any device on NMEA 2000. Each display can be setup for output­ting dierent NMEA 0183 sentences.

¼ Note: When bridging data from ethernet, an NSS display has to be nominated to bridge

the data. If this nominated display is turned o, no data will be displayed, until the display is
turned on or another display is selected to bridge the data.

¼ Note: NMEA 0183 to NMEA 2000 bridging only applies to the NMEA 0183 sentences outlined

in the “NMEA 0183 supported sentences” on page 61.

¼ Note: For high speed heading data input in to a radar for MARPA functionality, conversion

should be done via an AT10HD.

NMEA 2000 / SimNet | NSS Installation Manual

NMEA 2000 / SimNet setup

Setup is required on initial start up of the system, or if any part of the NMEA 2000 network has
been changed or replaced.

From ‘Network’ in the main system settings menu you can:

• select NMEA 2000 data sources - either automatically or manually

• congure instance numbers for NMEA 2000 devices (where multiple sources of same data

exist)

• control how device parameters backlighting, units, damping, and alarms are grouped on the

network

• select to share waypoints via NMEA 2000

• monitor NMEA 2000 network bus state and reliability

• control data damping

• calibrate water speed derived from a NMEA 2000 source

Auto Select (Source Selection)

The Auto Select option will look for all sources connected to the NSS system. If more than
one source is available for each data type, the NSS will automatically select from an internal
priority list.

Make sure all devices are connected and are turned on before selecting the Auto Select
option.

Manual source selection

Manual selection is generally only required where there is more than one source for the same
data, and the automatically selected source is not the one desired.

Group source selection

Simrad products such as NSS, NSE, and IS40, have the ability to;

• use data sources (eg position, wind direction, etc) that all other products on the network use,

or alternatively use a data source independently from other units.

• globally change all displays over to a dierent source from any display. (This will only include

products set to a Group mode.)

In order to enable group selection, the display must be set to ‘Default’ group.

In some cases it may be desired that an NSS on a network receives the same type of data, but
from dierent sources to that of the rest of the network devices. To do this set the data Group
setting to None, and select a source for the data

Advanced source selection

This allows the most exible and precise manual control over which devices provide data to
the NSS

Some data sources, such as those for fuel level, or engine RPM, can only be changed via the
Advanced menu. Occassionally Auto Select may assign sources incorrectly, which may be

|

35

NMEA 2000 / SimNet | NSS Installation Manual

corrected using the Advanced Source Selection. An example of this is where twin installations
with NMEA 2000 compliant engines are not programmed with unique instance numbers.
This means that the auto select feature can’t determine which engine is tted on the port and
which is tted on the starboard side.

Network Groups

It is also possible to group certain settings so they are duplicated across the network on
multiple displays. Display (ie backlighting), units, damping, and alarms can be grouped either
in ‘Default’ group, or groups ‘1’ through to ‘6’. If any of the settings require discrete control, set
it to ‘none’.

Ethernet (NETWORK port) | NSS Installation Manual

Ethernet (NETWORK port)

The NSS system uses an Ethernet network to interconnect high bandwidth devices such as
radar, echosounder and to another NSS, NSE or NSO displays. The NSS7 and NSS8 displays
have one network port each, whereas the NSS12 has three Ethernet ports. Navico Ethernet
network cables have orange connectors that are retained by a bayonet type locking collar.

¼ Note: a maximum of two NSS may be connected to the same network.

Connecting directly to a single device

The Ethernet port is auto sensing, meaning that the NSS can connect to one Network module
directly with out the use of a cross over cable or switch.

Broadband Radar

If the number of ethernet devices exceeds the number of available ports on the NEP-2, it is

Ethernet (NETWORK port) | NSS Installation Manual

Ethernet setup

No special setup is required for establishing an ethernet network, it is all ‘plug and play’ . An
NEP-2 connected between an NSS and another network module (e.g. BSM-1) will automati­cally start working, and relay data between the two devices.

Diagnostics

The UDB (User Data Base) tab on the diagnostics page, provides information on Ethernet
activity, which is presented in two tables as shown below.

Databases

The upper table gives an account of the various automatically synchronised databases that
ensure Simrad display units (NSS, NSE, NSO, plus B&G Zeus, and Zeus Touch) are all using the
same user settings and data. Each unit stores the database locally, so that all information is
available if the device is run in standalone. Databases can become unsynchronised when one
or more displays in a multi display network are not powered up while other displays are being
operated. Creation of waypoints, routes, tracks, and altering global settings all aect databas­es. When the tick box ‘Dirty’ is ticked, the unit has identied that it’s database is older than that
of another device on the network. The tickbox should clear within seconds of both devices
being powered up, and the databases synchronising. If it does not clear, it is recommended
that all devices have the power cycled.

IP addresses

The lower table shows the IP address of the display being viewed (top of list), the Master
display (with a tick next to it), and any other displays in a multi display network. The function
of the Master is invisible to the end user - It manages database synchronisation, however this
task automatically shifts to another display if the current master is shut down. The IP address
list only refreshes after all devices on the network have been powered down - a single device
that is shutdown on the network will not be removed from the table shown on other devices.
When powering up a system that has been completely shutdown, a network connectivity
issue can be identied if a display does not show any other IP addresses than it’s own.

The ‘UDB version’ is dependant on the software version installed on the display. It will never
change on it’s own, unlike the ‘Version’ of the Databases on the upper table. It is preferable to
have all UDB versions the same. This can usually be acheived by loading the latest software on
to your display - refer to “NSS software updates” on page 50.

Module network light

The network LED on modules such as NEP-2, BSM-1, and RI10, can be useful for determining if
the network is fundamentally operational. No light indicates no connection. A rapidly blinking
green LED means the network module is communicating with another device.

Autopilot | NSS Installation Manual

Autopilot

The Simrad NSS includes complete autopilot integration. When an NSS is connected to a
compatible Simrad Autopilot Computer (AC12, AC42, and SG05), you will have complete
control, setup and integration with your autopilot. The NSS display can be used in conjunc­tion with Simrad OP10, AP24, or AP28 Control units or the NSS can be used alone to conserve
dash space.

Wiring the autopilot system

Using the AC12 or AC42 autopilot computer

Autopilot setup

Verifying the autopilot connection

When an AC12N, AC42N, or SG05 is connected to the NSS system, the NSS will automatically

detect the autopilot and an Autopilot menu item will be included in the ‘Settings’ menu.

If no ‘Autopilot’ item is available in the menu, establish the connection by running the auto
select process.

The auto select process may also be used if the list of data sources needs to be updated when
a unit has been physically replaced.

If the AC12, AC42 or SG05 is later disconnected, the ‘Autopilot’ menu item will remain avail­able, but only a few of the menu items will be available.

Commissioning the autopilot

When the autopilot installation is completed, the commissioning procedures must be per­formed. Failure in setting up the autopilot correctly may prohibit the autopilot from function­ing properly.

The setup of the autopilot computers (AC12N/42N) can be done in full from either an NSS/
NSE/NSO unit, IS40 Display, or from an AP24/AP28 control head. The following sections
describe how you congure the autopilot from the NSS unit.

If you connect the NSS to an already commissioned autopilot system, you only have to do an
automatic source selection as described above before the autopilot is ready to be used.

Dockside setup

Initiating the required dockside setup is done from within the Commissioning dialog. Com­pleted procedures are labelled with a tick.

When the autopilot computer is delivered from factory AND ANY TIME AFTER AN AUTOPILOT
RESET HAS BEEN PERFORMED, you will have to run a complete setup again.

All steps in all commissioning procedures are clearly described on-screen, and you will be
guided step by step through the process.

1.

Press the ‘STBY/AUTO’ key to ensure that the autopilot is in standby mode

2. Activate the autopilot commissioning dialog as shown above

3. Select boat type

• The boat type setting is used by the system to select appropriate preset steering parameters.

It will also aect available autopilot features.

4.

Perform the rudder calibration

• Used if you have a rudder feedback unit installed. This calibration is used to ensure that the

physical rudder movement corresponds to the rudder angle displayed on the NSO unit.

VRF (Virtual Rudder Feedback) calibration

• The Virtual Feedback option enables your autopilot to steer without a conventional rudder

feedback unit. This function is designed for vessels up to 40 ft. powered by outboard or stern
drives only.

• The Virtual Feedback option will only be available when there is no feedback unit connected

at rst time turn on, or at turn on after an autopilot reset.

¼ Note: Installing a feedback unit will enhance the performance of the autopilot and provide an

42 |

accurate rudder angle indicator on the autopilot display. Unless impractical or impossible, a
rudder feedback unit should be installed.

5.

Set the drive voltage

• Refer to the drive unit table in the AC12N/AC42N Installation manual or to your drive unit

documentation for information.

6.

Run the rudder test as described in the on-screen instructions

¼ Note: If the boat uses power assisted steering, it is important that the engine or electric mo-

tor used to enable the power assist steering is 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!

• When this test is started the autopilot computer will issue a series of PORT and STBD rudder

commands and automatically verify correct rudder direction. It detects minimum power to
drive the rudder and reduces the rudder speed if it exceeds the maximum preferred speed
(8°/sec.) for autopilot operation. The system will also detect whether the drive unit is a revers­ible motor or if a solenoid valve is operated.

Rudder drive setup

The rudder drive setup controls how the autopilot computer controls the steering system.

Drive voltage

Voltage specied for your drive unit.

The Drive unit voltage setting does not apply when the system
operates solenoids on a continuous running pump/steering gear.
Hence, the output voltage to the solenoids will be the same as the
input voltage.

Refer to the drive unit table in the AC12N/AC42N Installation manual
or to your drive unit documentation for information.

!

Warning: Selection of improper voltage level for your drive unit may damage both the

drive unit and the AC12N/AC42N even if the protection circuits are activated.

Drive engage

Clutch This is the default setting and it allows you to steer the boat with the helm or

wheel when in STBY mode (FU and NFU modes) as well as in all auto steering
modes

Auto This option is typically used to switch between two rudder speeds on a continu-

ous running pump, used when dierent rudder speeds are required for automatic
and Follow-up/Non-Follow-up steering

Motor output

Shows the amount of power needed to achieve the correct rudder speed. The reading is
obtained from the Rudder test.

The automatically set value may be increased or decreased.

Rudder deadband

This parameter is used to prevent the rudder from hunting. The reading is obtained from the
Rudder test which optimizes the deadband to the speed of the boat and the pressure on the
rudder.

If the auto-setting does not perform properly due to high inertia from the wheel or a loose
steering gear, it can be adjusted manually. Find the lowest possible value that will prevent the
rudder from continuous hunting. A wide deadband will cause inaccurate steering.

¼ Note: The rudder deadband setting is not available when the autopilot is congured for

Virtual Rudder Feedback.

Seatrials

A seatrial can only be performed if the dockside settings are completed and conrmed.

The seatrial must always be performed in open waters at a safe distance from other trac.

|

43

Autopilot | NSS Installation Manual

¼ Note: You can switch the autopilot to standby mode and take manual control of the boat at

any time during the seatrial by pressing the ‘STBY/AUTO’ key.

The following seatrial calibration should be done:

• Compass calibration; used to automatically compensate for on-board magnetic interference

• Compass oset adjustment, used to compensate for a xed oset in the nal heading

readout

• Wind vane oset to compensate for a wind vane that is not mounted facing in exactly the

same direction as the bow of the vessel (dead ahead)

• Boat speed calibration

• Transition HI/LO speed setting (the speed at which you want to change the set of steering

parameters)

• Automatic tuning of the steering parameters

• Setting the seastate lter

• ‘Saiboat Setup’ menu items

Compass calibration

Before the compass calibration is started, make sure that there is enough open water around
the vessel to make a full turn.

The calibration should be done in calm sea conditions and with minimal wind to obtain good
results. Follow the on-screen instruction, and use about 60-90 seconds to make a full circle.

During the calibration, the compass will measure the magnitude and direction of the local
magnetic eld.

• If the local magnetic eld is stronger than the earth’s magnetic eld (the local eld is reading

more than 100%), the compass calibration will fail

• If the local eld is reading more than 30%, you should look for any interfering magnetic

objects and remove them, or you should move the compass to a dierent location. The
(local) eld angle will guide you to the local interfering magnetic object.

¼ Note: Calibration must be made on the compass that is active for the autopilot. If the com-

pass is not possible to initiate calibration from the device list on the NSS, refer to the compass’
own instructions regarding calibration.

¼ Note: In certain areas and at high latitudes the local magnetic interference becomes more

signicant and heading errors exceeding ±3° may have to be accepted.

Compass mounting oset

After compass calibration, the dierence between the compass lubber line and the boat’s
center line should be compensated for.

44 |

Autopilot | NSS Installation Manual

Magnitude of local eld in
% of earth’s magnetic eld.

LUBBER LINE

Direction of local eld with
respect to lubber line. It can
also be on the reciprocal.

1. Find the bearing from the boat position to a visible object. Use a chart or a chart plotter

2. Steer the boat so that the center line of the boat is aligned with the bearing line pointing towards the

object

2. Change the oset parameter so that the bearing to the object and the compass readout becomes

equal. Refer graphic above

¼ Note: Make sure that both the compass heading and the bearing to the object have the same

unit (°M or °T).

Setting the Transition speed (HI/LO)

This is the speed at which the system automatically changes from
LO to HI steering parameters.

On power boats it is recommended that you set a value that
represents the speed where the hull begins to plane or the speed
where you change from slow to cruising speed.

On sailboats the transition speed should be set to around 3-4
knots to give the best response in a tack.

A deadband of 2 knots is incorporated to prevent oscillation of
HI/LO settings when vessel is travelling at the transition speed.

Transition to LO parameters with
increasing speed: 10kn

Transition speed set to 9kn

Transition to HI parameters with
decreasing speed: 8kn

LO response

HI response

Active response parameter set is shown in the autopilot popup, and the following abbrevia­tions are used:

45

Autopilot | NSS Installation Manual

HI-A High response parameters set automatically
LO-A Low response parameters set automatically
HI-M High response parameters set manually
LO-M Low response parameter set manually

Autotuning

The autotune feature will run the boat through several tests and then automatically set the
most important steering parameters.

Autotune is not required for the autopilot to function, as it is preset with steering parameters
that should steer most boats in the 30-50 foot range.

You can manually adjust all parameters that are set during autotuning.

Seastate lter

The Seastate lter is used to reduce rudder activity and autopilot sensitivity in rough weather.

OFF Seastate lter is disabled. This is default
AUTO Reduces rudder activity and autopilot sensitivity in rough weather by an

adaptive process. The AUTO setting is recommended if you want to use the
seastate lter

MANUAL Linked to the steering response control settings described previously. It may be

used to manually nd the optimum combination of course keeping and low
rudder activity in rough but steady sea conditions

Setting sailing parameters

¼ Note: Sailing parameter settings are only available if the

boat type is set to Sail.

Tack time

When performing a tack in WIND mode, the rate of turn
(tack time) can be adjusted. This will give single-handed
sailors time to handle the boat and the sails during a
tack.

A turn performed without shifting wind side, will also
be made at a controlled turn rate.

Range Change per step Default Units

2 - 50 1 12 seconds

Tack angle

This value is used to preset the course change used when tacking in AUTO mode. By pressing
the left/right arrow keys the course will change as much as this value.

Range Change per step Default Units

50 - 150 1 100 °

Wind function

With wind function set to Auto, the autopilot will automatically select between apparent and
true wind steering. Auto is default and recommended for cruising.

When the boat is running or on a broad reach, there is a heightened chance it will surf on the
waves. This may lead to signicant changes in boat speed, and thereby changes in apparent
wind angle. True wind steering is therefore used to prevent undesired corrections by the au­topilot when heading downwind (or close to), while steering to apparent wind is used when
beating or reaching.

Apparent wind steering is preferred when you want to maintain maximum boat speed
without continuous trimming of the sails.

VMG optimizing

You can optimize the VMG to wind. When selected the function will be active for 5–10
minutes after a new wind angle has been set and only when beating.

46 |

Autopilot | NSS Installation Manual

Layline steering

Layline steering is useful when navigating. Cross Track Error (XTE) from the navigator will keep
the boat on the track line. If the XTE from the navigator exceeds 0.15 nm, the autopilot will
calculate the layline and track towards the waypoint.

Manually adjusting steering parameters

The autotune function in the autopilot is so rened that the majority of boats will need no
further adjustments of the steering parameters. On some boats however, or in particular
sea conditions, ne tuning of the steering parameters may improve the performance of the
autopilot.

Transition speed

Refer previous description.

Rudder

This parameter determines the ratio between commanded rudder and the heading error. The
higher rudder value the more rudder is applied.

If the value is too small it will take a long time to compensate for a heading error, and the
autopilot will fail to keep a steady course.

If the value is set too high the overshoot will increase and the steering will be unstable.

Counter rudder

Counter rudder is the amount of rudder used to try to prevent the boat from yawing around
the set course. Higher counter rudder settings result in more rudder being applied.

The best way of checking the value of the Counter rudder setting is when making turns.

The gures illustrate the eects of various Counter Rudder settings;

A: Counter rudder too low; overshoot response

B: Counter rudder too high; sluggish and creeping response

C: Correct setting or counter rudder; ideal response

A B C

Auto trim

This parameter denes how fast the autopilot shall correspond after having registered a
heading error.

The standard value is 40 seconds which should work well on most boats. Rule of thumb: Set
to same value (seconds) as the boat’s length in feet. On boats operating on VRF the value
should be set to 20 seconds.

Rate limit

Sets the maximum allowed rate of turn.

The value should be kept at 6.0°/second unless there is a need for more rapid response in
turns.

Minimum rudder

This parameter lters small rudder commands to prevent high rudder activity.

Some boats may have a tendency to not respond to small rudder commands around the
“course keeping” position because of a small rudder, a rudder deadband, whirls/disturbance of
the water-stream passing the rudder or it is a single nozzle water jet boat.

|

47

Autopilot | NSS Installation Manual

By increasing the Minimum rudder parameter you may improve the course keeping
performance on some boats. This will however increase the rudder activity.

Minimum wind angle to port and starboard

These parameters should be set identical to the minimum apparent wind angle that
will keep the sails from stalling and maintain boat speed. The parameters will vary
from boat to boat.

The settings are used for the tack-prevent function. They also apply when the autopi­lot is operating in WindNAV mode.

You can select dierent minimum wind angles for port and starboard. The dierence
between port and starboard will be taken into account when calculating the Distance
To Turn (DTT).

Navigation change limit

This parameter denes the maximum course change that the autopilot is allowed to
make when the NSS is following a route (NAV steering).

If the required course change to the next waypoint in a route is more than the set
limit, you are prompted and must acknowledge the course change before the autopi­lot will turn the vessel.

CZone connection to NMEA 2000 | NSS Installation Manual

CZone connection to NMEA 2000

When interfacing to C-ZONE network it is recommended to use a BEP Network interface
bridge (A) to join the two network backbones together.

The CZONE / NMEA 2000 Network interface bridge isolates the power of the two networks,
but allows data to be freely shared between both sides.

The Network Interface has built in terminators so needs to be placed at the extremity of each
network backbone.

The Interface Bridge can also be used for expansion of the NMEA 2000 network, when the
maximum node limit (node = any device connected to network) for the network has been
reached or the maximum cable length of 150m will be exceeded. Once an Interface Bridge
has been tted, a further 40 nodes and additional cable length can be added.

The Network Interface is available from your BEP dealer. For more information please refer to
the BEP web site www.bepmarine.com.

CZone connection to NMEA 2000 | NSS Installation Manual

CZone setup

In order to communicate with the CZone modules connected to the network, the NSS display
must be assigned a unique CZone Display Dipswitch setting.

The functionality of the CZone system is determined by the CZone Cong File (.zcf), which
is stored on all CZone modules and supported Simrad displays, such as the NSS. The le is
created using the CZone Conguration Tool, a specialised PC application available from BEP
Marine Ltd, and associated CZone distributors.

The NSS system provides a means to load the Cong le, as well as apply updates to module
rmware, removing the need to take a laptop computer aboard the vessel.

Enabling CZone functionality

Once CZone is enabled, an addtional CZone menu appears at the bottom of the Settings
page.

Assigning the dipswitch setting

Every Simrad product capable of controlling and viewing CZone devices must be assigned
a virtual dipswitch setting. This setting is unique for each device. Typically it is set after the
cong le already exists on the CZone system, but it may also be set in advance. To do so,
access the CZone menu on the Settings page.

When the cong is already available on the network, it will immediately commence upload­ing to the NSS once the dipswitch is set. Allow this to complete, without interruption.

Setting CZone to display at startup

With this option selected, the CZone control page will be shown rst, every time the NSS is
powered up.

CZone backlight control

Enabling this will cause the NSS to synchronize it’s backlight setting with that of any CZone
Display Interfaces set up to share backlight settings.

Import and backup a cong le

The les page may be used to import CZone cong les, or export a copy to a Micro SD card.
Importing will overwright the existing le on the NSS and all connected CZone devices.

For further information refer to “Backing up user data” on page 50

Upgrading module rmware

The les page also allows the loading of CZone module rmware updates. For further infor­mation refer to ”NMEA 2000 and Ethernet device updates” on page 51

Software Updates and Screen Calibration

From time to time Simrad releases software updates to it’s existing products. Updates are
created for a variety of reasons; to add or improve features, to add support for new external
devices, or to x software bugs.

Updates can be found on the Simrad website: http://www.simrad-yachting.com/Downloads/
Software-Updates/

The NSS may be used to apply software updates to itself, and to supported NMEA 2000 and
CZone devices, with les read o a Micro SD card.

Before initiating an update to the NSS itself, be sure to back up any potentially valuable user
data.

Backing up user data

There are two les that can be backed up that relate to user changes:

• Waypoints Routes and Tracks

• Settings (includes preferences such as unit settings, custom new pages, and Czone congura-

tion les)

The backup procedure is similar for both.

The le formats for waypoint backup:

• User data le version 4: Use with current Navico MFDs (NSE, NSO, HDS). Oers most detail

• User data le version 3 (with depth): Use with legacy Lowrance GPS chartplotters

• User data le version 2 (no depth): Use with legacy Lowrance GPS chartplotters

• GPX (GPS Exchange): Use with some other manufacturers’ GPS products, and PC applications

• Northstar .dat (no Tracks): Use with legacy Northstar chartplotters

The Serial port option outputs the waypoints over NMEA 0183. The receiving GPS/PC will typi­cally need to be set to allow import of waypoints.

The Settings and Czone cong can be copied simply by selecting which you want to backup
and selecting the destination to save to.

If the NSS is defaulted, or user data is accidentally deleted, simply return to the les page,
highlight the backup le, and select ‘Import’. View le details for creation date.

NSS software updates

The update le must be loaded to the root directory of the SD card.

In the les menu, locate the update le on the SD card and select ‘Upgrade’. Accept the
prompt to reboot the unit, and wait a few moments as the unit restarts. After a fews seconds
the unit will display something similar to the following image:

Select update to run

* 0: Cancel

1: “NSS-xxxx.upd”

Turn the rotary knob so that the asterix appears next to the update le. Press the rotary knob

51

CZone connection to NMEA 2000 | NSS Installation Manual

to commence update. Do not remove the Micro SD card or repower the NSS until the process
is completed (this will typically take no more than a couple of minutes).

NMEA 2000 and Ethernet device updates

To update SimNet and ethernet devices select the Upgrade option presented when the le
is highlighted, followed by conrmation of the device you wish to upgrade. Do not interrupt
the upgrade process.

Touch Screen Calibration

1. Turn the unit o

2. Press and hold the MENU key, then turn the unit on

3. Hold the MENU key during power on, until the calibration utility screen comes up

4. Touch crosshair shown on screen to perform nine point calibration

5. After successful calibration the unit will return to normal application screen

Maintenance | NSS Installation Manual

Maintenance

Preventive maintenance

The NSS unit does not contain any eld serviceable components, therefore the operator is
required to perform only a very limited amount of preventative maintenance.

It is recommended that you always t the supplied protective sun cover when the unit is not
in use.

Simple maintenance procedures

Cleaning the display unit

The supplied cleaning cloth should be used to clean the screen, where possible. Use plenty of
water to resolve and take away salt remains. Crystalized salt may scratch the coating if using a
damp cloth. Apply minimal pressure to the screen.

Where marks on the screen can’t be removed by the cloth alone, use a 50/50 mixture of warm
water and isopropyl alcohol to clean the screen. Avoid any contact with solvents (acetone,
mineral turpentine etc.), or ammonia based cleaning products, as they may damage the anti­glare layer, plastics bezel, or rubber keys.

To prevent UV damage to the plastic bezel and rubber keys, it is recommended that the sun
cover be tted when the unit is not in use for an extended period.

Cleaning the media port door

Clean the media port door regularly to avoid that salt crystallize on the surface, causing water
to leak into the card slot.

Checking the keys

Make sure that no keys are stuck in the down position. If one is stuck, wiggle the key to free it
back to normal.

Checking the connectors

The connectors should be checked by visual inspection only.

Push the connector plugs into the connector, if the connector plugs are equipped with a lock;
ensure that this is in the correct position.

Software upgrades

The latest software for the NSS will be available for download from our web site;

www.simrad-yaching.com.

Detailed instructions for how to install the software will follow the upgrade les.

For more details about software upgrades, refer to Software updates in Chapter 15.

Trouble shooting

Failure Corrective action

One or more functions do not operate as
normal

Perform a back to factory as described in
“Restore defaults” in System Settings.

Normal operation is not possible and back
to factory does not x the problem

Switch o the unit, press and hold the
zoom in and out keys and switch on the
unit. Release the zoom keys after some 5-6
seconds. A second beep conrms the reset.

Maintenance | NSS Installation Manual

Backing up your system data

Waypoints, routes, tracks that you create are led on your system. It is recommended to regu­larly copy these les and your system settings les as part of your back-up routine.

The les are copied to a Micro-SD card inserted in the card slot on the front of your unit.

Dierent output formats are available:

User Data File version 4 This is best used when transferring data from one

NS* system to another, since it contains all the extra
tid bits of information these systems store about
items.

User Data le version 3 ( with depth) Should be used when transferring user data from an

NS* system to a legacy Lowrance ( LMS, LCX, etc )

User data le version 2 (no depth)

GPX (GPS Exchange) This is the format most used on the web that shares

among most GPS systems in the world. Use this
format if you are taking data to a competitors unit.

Northstar.dat (no Tracks) Used to transfer data to a legacy Northstar device.

The example shows how to export waypoints, routes and tracks. Selection is done by using
the rotary knob or the menu.

1.

Select les

2. Press the rotary knob to access the export dialog, and select the le format you want to export to

3. Select destination folder

4. Enter name for exported le
