NSS evo2 overview

The NSS evo2 range of multifunction displays consist of rugged marine displays with built
in powerful marine processors. Display size choices are 6.4”, 9”, 12” and 16”. All models come
with a built in 10 Hz high gain GPS antenna. All display sizes also have a built in CHIRP echo
sounder and StructureScan. The 6.4” and 9” models are also available as “M”versions - charting
only, without inbuilt echo sounder.

The ability to network over NMEA 2000 and ethernet allows access to data as well as control
of numerous optional devices that can provide sonar, radar, audio entertainment, weather
and even digital switching.

All displays can operate on 12 V or 24 V systems.

Each size display may be flush or bracket mounted. The 6.4”, 9”, and 12” include a gimbal
bracket, however the 16” requires an optional VESA bracket adaptor, to mount to a suitably
sized VESA bracket.

Hardware installation

Display 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.
Simrad displays are high-contrast and anti-reflective, 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.

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

The mounting location will affect the internal GPS receiver. Metals, thick fibreglass and other
dense materials above the receiver may block GPS signal. Test the unit in it’s intended location
to ensure satisfactory reception. An external GPS source may be added to overcome poor
reception areas.

Leave sufficient clearance to connect all relevant cables.

Check that it is possible to route cables to intented mounting location.

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

Choose an area where the unit will not be subjected to excessive vibration, or heat.

Choose a location that will not expose the unit to conditions that exceed the IP rating - refer
to “Specifications” on page 45.

¼ Note: Where flush mounted, the enclosure 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 off the heat sink, and sunlight heating of the enclosure. In very
small enclosures, it may be required to fit forced cooling.

!

Warning: Inadequate ventilation and subsequent overheating of display may

cause unreliable operation and reduced service life. Ensure enclosure does not con­sistently exceed +55° C (+131° F) during normal daytime operation (in direct sunlight,
and at full screen brightness).

!

Warning: When installing, ensure appropriate safety equipment is used, e.g. ear

mus, protective glasses, gloves and a dust mask. Power tools may exceed safe noise
levels, and can cast o dangerous projectiles. The dust from many materials common­ly used in boat construction may cause irritation or damage to eyes, skin, and lungs.

Display installation

Bracket mounting - 7”, 9” and 12” models

Place the bracket in the desired mounting location, and use a pencil or permanent marker to
mark drilling locations.

¼ Note: ensure that the chosen location has enough height to accomodate the display fitted in

the bracket, and allows tilting of the display. Also adequate space is required on both sides to
allow tightening and loosening of the knobs.

Use fasteners suited to the mounting surface material. If the material is too thin for self
tappers, reinforce it, or mount bracket with machine screws and large washers. Use only
304 or 316 stainless steel fasteners. Mark the screw locations using bracket as template, and
drill pilot holes. If mounting surface is steel, or carbon fibre, some form of isolating gasket
or sealant is recommended between the surface and the bracket. Also apply anti-seize
compound to the fasteners.

Screw down the bracket.

Mount the display to the bracket using the knobs. Hand tighten only. The ratchet teeth in
the bracket and display case ensure a positive grip and prevent the unit changing from the
desired angle.

¼ Note: If mounting location may be subject to salt water spray, consider using an anti-seize

compound on the thread of the knobs, to prevent them from binding with the unit.

Hardware installation | NSS evo2 Installation Manual

VESA adaptor mounting - 16” model

The NSS16 evo2 can be mounted using a wide range of 3rd party VESA brackets. To mount
the NSS16 to a VESA bracket the optional adaptor bracket must be fitted. A gimballing style
bracket, similar to those supplied with the NSS7/9/12, is not available for the NSS16.

!

Warning: the VESA bracket used should be of suitable strength and materials to

suit the harsh marine environment. Some standard domestic TV style brackets will not
suit potential G-forces applied, and could result in the display coming loose in rough
conditions. Use a bracket overrated for the weight and size of the NSS16 evo2.

Hardware installation | NSS evo2 Installation Manual

Flush mounting

Fit the small self adhesive decal to right side
of unit, covering rubber tab of SD card reader
gasket. Then attach self adhesive foam gasket to
rear of display.

Check the template for scaling accuracy, using a tape
measure or ruler against the ruler printed on the
template.

Cut away excess paper if required, and tape template
to mounting surface. Check it is correctly aligned to a
vertical or horizontal reference. Do not use a bubble
level as vessel may be listing! Adjust where required.

Drill all marked pilot holes, then using an appropriate
saw, cut through the template and mounting surface,
along the dotted line bordering the shaded area of the
template. Stay within 1mm of the dotted line.

Check the fit of the display, and file away remaining
obstructions. Secure the display with the supplied
screws. Once screws are fully tightened, ensure there
is complete contact with the mounting surface. If
machine screws are required, use only M2.5 (3/32”)
size with a head diameter no greater than 5.6mm
(7/32”).

¼ Note: please ensure mounting surface is completely

flat. Make adjustments to mounting surface if fasten­ing in place puts product under tension.

Bezel Fitment and Removal

When fitting bezels, ensure hook tabs on
back of each bezel recess in to opposing
slots on screen frame. Once flush with front
surface of screen, slide top bezel to the left,
and bottom bezel to the right to lock in to
place. The bezel trim have been designed
to be very low profile, and therefore fully
conceal the locking tabs that keep them
from being accidentally disengaged from
the mounting flange. To release the locking
tab, it is necessary to gently lever the centre
of the bezel trim away from the mounting
flange. To remove the cover, simultaneously
slide it sideways; to the right for the top
bezel, and to the left for the bottom bezel.

Hardware installation | NSS evo2 Installation Manual

Transducer mounting location

The NSS evo2 displays (with exception to the ‘M’ models) are fitted with both StructureScan
and Chirp sonar capability and may be connected to a variety of transducers.

The chirp sonar connector suits all standard blue connector transducers, including
conventional and wide frequency band (ie chirp) models. Both include in-hull, through-hull,
and transom mount options.

The StructureScan connector has two options; the transom mount transducer and the
through hull transducer. Structure scan transducers are not suited to in-hull installation.

Transducer location selection and installation are two of the most critical steps in sonar
installation. To function properly the transducer must be in the water at all times, and in a
location that has a smooth flow of water when the boat is moving.

¼ Note: StructureScan and Chirp can’t be operated simultaneously on the NSS evo2. If simulta-

neous operation is desired, an external module such as the LSS-2, SonarHub, BSM-2, or second
NSS evo2 must be fitted.

Research

Before starting the installation of the transducer, it’s advised to check the following;

• Find out if the boat builder has a recommended installation location

• Establish direction of rotation of the propeller(s) - where mounting level or aft of propellor(s)

• Watch actual water flow when boat is travelling at cruising speed to determine the area of

transom with cleanest flow (least bubbles)

Avoiding common turbulence areas

The primary aim is to stay clear of propeller and hull generated turbulence, while mounting
the transducer as close to the center of the vessel as possible.

3

5

4

1 Avoid mounting within 1m (3.3’) to port of propeller

2 Conventional clockwise propeller rotation

3 Avoid mounting within 7.5cm (3“) to starboard of propeller

4 Best mounting location - undisturbed water ow

5 Planing strake - avoid mounting behind here

¼ Note: Reverse the distance guides (1 & 3) from propeller where engine is of counterclockwise

configuration.

¼ Note: Boats with strakes or ribs on the hull can create large amounts of turbulence at higher

speeds. A good transducer location on these types of boats is between the ribs closest to the
engine.

¼ Note: If the transducer is not placed in a smooth flow of water, interference caused by

bubbles and turbulence may show on-screen in the form of random lines or dots. The unit
could also lose bottom signal when the boat is on plane.

¼ Note: Trim tabs will vary in the amount of turbulence they create as they are adjusted, stay

clear of these.

Hardware installation | NSS evo2 Installation Manual

Attaching the Transducer

Due to the large range of transducer options, it is not practical to cover all scenarios here.
Please refer to the documentation included with the transducer for directions on physical
installation.

!

Warning: Most transducer installations require drilling holes below the vessel

water line. Incorrect installation methods could result in water ingress in to the bilge
or in to laminations of the hull material. The results could be damaging to the ves­sel or dangerous to people aboard. Amateur installers are strongly recommended to
consult with a professional installer or boat builder.

Wiring | NSS evo2 Installation Manual

Wiring

Guidelines

Care must be taken when running cables in a boat, to ensure that the cables are protected
from damage and do not interfere with mechanical systems such as throttle cables and hatch
covers.

At each end of a cable, it is advisable to leave a short loop hanging lower than the termination
point. This prevents any water that may get in contact with the cable from running down it to
termination points vulnerable to corrosion.

Extending cables should be done with suitable crimp connectors or solder and heat shrink.
Keeps joins as high as possible to minimize possibility of water immersion.

Routing cables adjacent to high current or high frequency signal cables could cause noise to
be induced from one device to another. Allow spacing between cables where possible.

Secure all cables at regular intervals, to prevent movement during boat operation. Cable
movement may cause fatigue at termination points or cause the cable to interfere with other
boat systems.

Allows enough cable slack for easy access to connectors when removing the device from a
bracket or flush mount installation.

!

Warning: Before starting the installation, be sure to turn electrical power o. If

power is left on or turned on during the installation, re, electrical shock, or other
serious injury may occur. Be sure that the voltage of the power supply is compatible

!

Warning: The positive supply wire (red) should always be connected to (+) DC with

a suitable fuse or a circuit breaker (closest available to fuse rating).

Power connection

NSS evo2 displays are designed to be powered by a 12 or 24 V DC system. They are protected
against reverse polarity, under voltage and over voltage (for a limited duration). A fuse should
be fitted to the positive supply; 3A for the 7” & 9” models, and 5A for the 12” and 16” models.

Power Control connection

The yellow Power Control wire on the NSS evo2 power cable can either be an input that will
turn on the processor when power is applied, or an output that turns on other devices when
the processor is powered on. It can be configured at the installation stage to control the
power state of displays and compatible devices. When commissioning the system, the NSS
evo2 can be set to be a Power Control Slave or Power Control Master.

Power Control configuration options of the NSS evo2 are:

If the left NSS evo2 turns on using the power button and is set as the Power Control Master,
it will output voltage on the Power Control bus to power on the other NSS evo2, the Radar
Interface, and the SonicHub.

If the right NSS evo2 is set to Power Control Slave, it cannot be powered down using its own
power button, but can be set to standby.

If the left NSS evo2 (Power Control Master) is off, the right NSS evo2 can be turned on using
its own power button, but won’t turn on any other devices.

To turn on all network devices from either NSS evo2, both devices can be configured as Power
Control Masters.

¼ Note: If an NSS evo2 has its power state controlled by another device or ignition switch (and is

set as Slave), it can’t be powered down independantly. It can however be placed in a standby
state to save power.

External alarm

An external alarm can be connected to one or more NSS evo2 displays on the network, via
the blue wire. The external alarm can be a small peizo buzzer connected directly, or a horn
siren connected via a relay.

Alarms are configured globally in the system i.e they can be configured on any one
networked multifunction device or IS40 instrument, and be seen, heard, and acknowledged
from all devices. Individual devices can also be configured to not sound their internal buzzer,
but still display the alarm information. For information on configuring alarms, refer to the
Alarms section in the Operator manual.

Connect sonar transducers

As most NSS evo2 models are equipped with internal StructureScan, Chirp sonar, and
conventional sonar, the transducer(s) are usually plugged directly in to the back of the unit.

Where required, premium external sonar sources such as BSM-2, may be connected via
ethernet.

NMEA 2000 / SimNet – connection to backbone

Device connection

The NSS evo2 multi function displays are equiped with an NMEA 2000 data port, which allows
the receiving and sharing of a multitude of data from various sources.

Essential network information

• The standardised physical cables/connectors for NMEA 2000 are ‘Micro-C’ and ‘Mini-C’,

directly derived from the automation industies ‘DeviceNET’ - ‘Micro-C’ being the more
commonly used size.

• While most Simrad products use ‘Micro-C’ cabling and connectors, some products still use

proprietary ‘SimNet’ connectors, which are easily made compatible via adaptor cables.

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

compliant devices

• 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, using Micro-C cabling, 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)

| 15

Wiring | NSS evo2 Installation Manual

Planning and installing a network backbone

The Micro-C backbone needs to run between the locations of all products to be installed ­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 the 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

• T-connector. Used to connect a drop cable to the backbone

• Micro-C power cables. Connected to backbone via a T-connector

¼ Note: When using a wind sensor, the mast cable should be connected at one end of the

backbone, as the sensor is fitted 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.

¼ Note: Simrad devices with Micro-C NMEA 2000 connectors are fully compatible with a Sim-

Net network by using a Micro-C to SimNet adapter cable.

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

the backbone, or wired individually off a drop cable. Connecting from device to device is
known as ‘daisy chaining’. This network topology is not officially NMEA 2000 compliant.

Power the network

The network requires its own 12 V DC power supply protected by a 5 amp fuse or breaker. For
vessels fitted with 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 that already has its own power supply, do

not make another power connection elsewhere in the network, and ensure existing network
is not powered by 24 V DC.

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

batteries, autopilot computer, radar, bow thruster or other high current devices.

NMEA 0183 device connection

The NSS evo2 display has an NMEA 0183 serial port, providing both an input and an output.
The port uses the NMEA 0183 (serial balanced) standard, and can be configured in the
software for different baud rates up to 38,400 baud.

1 NMEA 0183 RX_B (orange)

2 NMEA 0183 RX_A (green)

3 NMEA 0183 TX_B (blue)

4 NMEA 0183 TX_A (yellow)

¼ Note: The connector for NMEA 0183 is labelled VIDEO on rear of unit, as the cable is dual

purpose and carries both composite video and NMEA 0183 (on seperate wires).

Talkers and Listeners

Do not connect multiple devices outputing data (Talkers) on to the serial input (Rx) of the
unit. The NMEA 0183/RS422 standard is not intended for this type of connection, and data
will be corrupted if multiple devices transmit simultaneously. The output however may drive

multiple receivers (Listeners). The number of receivers is finite, and depends largely on the
receiving hardware. Typically driving three devices is possible.

Ethernet device connection

Ethernet is used to interconnect high bandwidth devices such as radar, sonar, and other multi
function displays. The NSS7/9 evo2 have one ethernet port, whereas the NSS12/16 evo2 have
two. Connection of network devices can be made directly, or via a NEP-2 ethernet expansion
port. Additional NEP-2s can be added to provide required number of ports.

¼ Note: some ethernet devices are equiped with two or more ethernet ports, which allow con-

nection of additional devices, and may eliminate the need for an extra NEP-2.

Video in

Each NSS evo2 can be connected to two composite video sources, and display video images
on its display. Both NTSC and PAL formats are supported. The NSS evo2 video input cable is
fitted with female RCA plugs - the camera cables should be terminated with male RCA cables
to suit.

Software setup | NSS evo2 Installation Manual

Software setup

The NSS evo2 requires some initial configuration before use, in order to get the most out of
the product.

The following sections focus on settings that typically will not require change once
configured. User preference settings and operation are covered in the operator manual.

Pressing the home key brings up the home page, which has three distinct panels.

The scrollable left column of icons access most settings that require configuration;

First time startup

When the NSS evo2 is started for the first time, or after a factory default, the unit will raise
prompts requesting the user to select some fundamental setup options;

Choose language.

Initiate source selection for data sources both internal and external to device.

Check all external data sources and NMEA 2000 data bus are turned on.

Simulation uses recorded data to allow product demonstration of features otherwise not
possible without physical installation on a vessel.

| 19

Software setup | NSS evo2 Installation Manual

Time and Date

Configure time settings to suit vessel location.

Power Control setup

Determines unit response to signal applied to yellow wire of power cable.

These settings do not require adjustment if the yellow wire is connected to ignition or to a
stand-alone switch that applies 12V/24V.

¼ Note: The System Controls menu will not display the ‘Power Off’ option when unit is config-

ured as slave. To power down device, the master device must be powered down, or system
power removed.

Source selection

Data sources provide live data such as GPS position, heading, wind speed, and temperature.
The data may originate from modules internal to the device (eg internal GPS), or external
modules connected via NMEA 2000 or NMEA 0183. The internal ‘virtual’ devices typically
include echo, MFD, Navigator, Pilot Controller, and iGPS. When a device is connected to more
than one source providing the same data, the user has the flexibility to choose the prefered
source. Before commencing with source selection make sure all external devices and the
NMEA 2000 bus are connected and are turned on.

Auto Select

The Auto Select option will look for all sources connected to the device. If more than one
source is available for each data type, selection will be made from an internal priority list. This
option will be suitable for the majority of installations.

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.

20 |

Software setup | NSS evo2 Installation Manual

Group source selection

Simrad multifunction displays, autopilot controllers, and instruments 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 different source from any display. (This will only include

products set to Group mode.)

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

Devices with the Group set to None can be set to use different sources to those of the rest of
the network devices.

Advanced source selection

This allows the most flexible and precise manual control over which devices provide data.

Some data sources, such as those for fuel level, or engine RPM, can only be changed via the
Advanced menu. Occassionally Auto Select may not assign the desired source, which may be
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 fitted on the port and
which is fitted on the starboard side.

¼ Note: the Advanced option is visible in multiple places - the bottom of the Sources list, and

under each source category (eg Compass). The latter shows a filtered list that only relates to
devices that output data relevant to the category.

Device list

The device list shows the physical and virtual devices that provide data. This may include a
module inside the NSS evo2, the NMEA 0183 port, or any external NMEA 2000 device.

Selecting a device in this list will bring up additional details and actions:

All devices allow allocation of an instance number via the Congure option. Set unique
instance numbers on any identical devices on the network. The Data option shows all data
being output by the device. Some devices will show additional option(s) specific to the
device - the RC42 illustrated above has a Calibration option, to allow easy setup of this
device which does not have it’s own user interface.

SimNet Groups

It is possible to group certain settings so they are duplicated across the network on multiple
displays. Display (ie backlighting), Units (ie metric, imperial), Damping (to dynamic data),

| 21

Software setup | NSS evo2 Installation Manual

and Alarms can be grouped either in ‘Simrad’ group, or groups ‘1’ through to ‘6’. If any of the
settings require discrete control, set it to ‘none’.

Diagnostics

The NMEA 2000 tab on the diagnostics page can provide information useful for identifying an
issue with the network.

Bus state simply indicates whether the bus is powered, but not necessarily connected to any
data sources. However if bus shows as ‘off’, but power is present along with an increasing error
count, it is possible that termination or cable topology is incorrect.

Rx Overows: The CAN driver got too many messages for its buffer before the application
could read them.

Rx Overruns: The CAN hardware got too many messages for its buffer before the CAN driver
could read them.

Rx/Tx Errors: These two numbers increase when there are error messages, and decrease
when messages are received successfully. These (unlike the other values) are not a cumulative
count. Under normal operation these should be at 0. Values around 96 upwards indicate
a heavily error prone network. If these numbers go too high for a given device, it will
automatically drop off the bus.

Fast Packet Errors: Cumulative counter of any fast packet error. This could be a missed
frame, or a frame out of sequence etc. NMEA 2000 PGNs are made of up to 32 frames. The
entire message will be discarded when a frame is missed.

¼ Note: Rx and Tx Errors often indicate an issue with the physical network, which may be

resolved by correcting termination, reducing backbone or drop lengths, or reducing the
number of network nodes (devices).

Damping

If data appears erratic or too sensitive, damping may be applied to make the information
appear more stable. With damping set at MIN, the data is presented in raw form with no
damping applied. This is available for heading, course over ground, speed over ground,
apparent wind, true wind, boat speed, depth, and tide sourced from NMEA 2000.

Calibration

An offset (positive or negative) can be applied to correct inaccuracies in boat speed, sea
temp, air temp, barometric pressure, and depth sourced from NMEA 2000.

External Alarm Setup

The ‘Siren Enabled’ option must be set in order for the unit to drive the buzzer when an alarm
condition arises. Its setting also determines the operation of the external alarm output.

Echosounder setup

Select echosounder source

If only one sonar source is present in the network, selection is not required as it should be
picked up automatically. However when more than one source exists (eg a BSM-2 or other
display with internal sonar), select the desired source in the Echo Settings.

22 |

Software setup | NSS evo2 Installation Manual

Network echosounder

Enabling network sounder allows the display to use other compatible sonar sources on
ethernet as well as sharing it’s own sonar with other devices.

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 offset is used:

A) For Depth below Keel: Set the distance from transducer to the bottom of the keel - this
should be set as a negative value.

B) For Depth Below Transducer: no offset required.

C) For Depth Below Surface (waterline): Set the distance from transducer to the surface - this
should be set as a positive value.

A B C

Echosounder software version

For external sounder modules, the software version is displayed in the header of the Echo
Installation dialogue. To upgrade Sonar software, see “NMEA 2000 and Ethernet device
upgrades” on page 39

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 records 10 knots the calibration value needs to be increased to 117 %. To calculate the
adjustment, divide the SOG by the paddlewheel speed, and multiply the product by 100.

Calibration range: 50-200 %. 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 five 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 influences 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.

| 23

Software setup | NSS evo2 Installation Manual

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 setup

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

Radar source

In a system with more than one radar, the correct device to configure can be selected from
this menu.

¼ Note: some radar like the broadband 4G support dual radar mode, and therefore are repre-

sented twice in the source list, with an A and B suffix.

Radar status

Scanner type

Identifies 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 insuranc.e 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

The earlier NSS model only supports 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
NSS because it may have an invalid Device ID. With the radar connected and powered 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, and only ap-

plies where a network combines NSS with NSS evo2.

24 |

Software setup | NSS evo2 Installation Manual

Adjust bearing alignment

This is to align 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 relative to the water surface. 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.

Sidelobe suppression

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.

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.

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 significant metallic clutter around the radar, sidelobe suppression may need to be
increased. The control should be adjusted as follows:

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

• 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.

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

• 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.

• Traverse the area again and readjust if sidelobe returns still occur.

• Exit the installation menu.

Restore radar to Factory Default

This can be used to revert all user adjustments.

Video In conguration

Press the menu key when on the video page or panel to open the setup
dialogue.

Enable PAL or NTSC depending on the video ouput standard of the selected
camera.

You can optimize the video display by adjusting the video image settings
(brightness, saturation, etc.). The settings are applied individually for each
video source.

Mirror image may be applied where the camera is providing a rear view, and
the user wishes to see objects as they would appear in a vehicle rearview

mirror, ie, on the same side as they actually are.

Autopilot setup

Verifying the autopilot connection

When an AC12N, AC42N, or SG05 is connected to the NSS evo2 system, the NSS evo2 will
automatically detect the autopilot and an Autopilot menu icon will be included in the
‘Settings’ menu.

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

If the AC12N, AC42N or SG05 is turned off independantly of the display, the ‘Autopilot’ menu
icon 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 compatible
Simrad displays that feature AP control, an IS40 Display, or from an AP24/AP28 control head.
The following sections describe how you configure the autopilot from the NSS evo2 unit.

If you connect the NSS evo2 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. Select the Commissioning option and clear following dialogue by pressing a STDBY/AUTO key;

3. Select boat type

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

It will also affect 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 NSS evo2 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

26 |

Software setup | NSS evo2 Installation Manual

at first 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

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 specified 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.

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 configured for

Virtual Rudder Feedback.

Seatrials

A seatrial can only be performed if the dockside settings are completed and confirmed. The
seatrial must always be performed in open waters at a safe distance from other traffic.

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 offset adjustment, used to compensate for a fixed offset in the final heading

readout

• Wind vane offset is 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 filter

• ‘Sailboat 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 field.

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

more than 100 %), the compass calibration will fail.

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

objects and remove them, or you should move the compass to a different location. The
(local) field 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 evo2, refer to the
compass’ own instructions regarding calibration.

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

significant and heading errors exceeding ±3° may have to be accepted.

Compass mounting oset

After compass calibration, the difference (if any) between the compass lubber line and the
boat’s center line should be compensated for.

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 offset parameter so that the bearing to the object and the compass readout

becomes equal.

28 |

Software setup | NSS evo2 Installation Manual

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.

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

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. All
parameters that are set during autotuning can be manually adjusted.

Seastate lter

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

OFF Seastate filter 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 filter

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

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

| 29

Software setup | NSS evo2 Installation Manual

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 significant 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.

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 refined that the majority of boats will need no
further adjustments of the steering parameters. On some boats however, or in particular
sea conditions, fine 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 figures illustrate the effects of various Counter Rudder settings;

30 |

Software setup | NSS evo2 Installation Manual

1 2 3

1 Counter rudder too low; overshoot response

2 Counter rudder too high; sluggish and creeping response

3 Correct setting of counter rudder; ideal response

Auto trim

This parameter defines 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 filters 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.

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 different minimum wind angles for port and starboard. The difference between
port and starboard will be taken into account when calculating the Distance To Turn (DTT).

Navigation change limit

This parameter defines the maximum course change that the autopilot is allowed to make
when the NSS evo2 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.

Fuel setup

The fuel utility monitors a vessels fuel consumption. This information is totalled to indicate
trip and seasonal fuel usage, and is used to calculate fuel economy for display on instrument
pages and the data bar.

To use the utility, a Navico Fuel Flow sensor, or a NMEA 2000 engine adaptor cable/gateway
with Navico Fuel Data Storage device must be fitted to the vessel. Neither the Navico Fuel
Flow sensor, nor the Suzuki engine interface require the use of a seperate Fuel Storage device.
Refer to the engine manufacturer or dealer for information on whether or not your engine
provides a data output, and what adaptor is available to connect to NMEA 2000.

Once physical connection is made, ensure source selection is completed. Multiple engine
installations using Fuel Flow sensors, or Fuel Data Storage devices, will require setup of related
engine location in the device list. For general source selection information refer to “Source
selection” on page 19.

¼ note: Multiple engines utilising a single gateway will not work with the Navico Fuel Storage

device.

Vessel setup

This dialog must be used to select the number of
engines, the number of tanks and vessel’s total fuel
capacity across all tanks.

Fuel ow conguration

Once the number of engines are set, it’s required to
set which fuel flow sensor is connected to which engine. Under ‘Device list’ on the Network
page, view the ‘Device Configuration’ page for each sensor, and set ‘Location’ to match the
engine the device is connected to.

‘Unconfigure’ is for defaulting the device clearing all user settings, and ‘Reset Fuel Flow’ will
restore only the ‘Fuel K-Value’ setting, if set in ‘Calibrate’. Only Navico devices can be reset.

Calibrate

Calibration may be required to accurately match measured flow with actual fuel flow. Access
calibration from the ‘Refuel’ dialog. Calibration is only possible on Navico’s Fuel Flow sensor.

1. Start with a full tank and run the engine as it would normally be operated.

2. After at least several litres (a few gallons) have been used, the tank should be fully refilled, and

the ‘Set to full’ option selected.

32 |

Software setup | NSS evo2 Installation Manual

3. Select the ‘Calibrate’ option.

4. Set the ‘actual amount used’ based on amount of fuel added to tank.

5. Select OK to save settings. The ‘Fuel K-Value’ should now show a new value.

¼ Note: To calibrate multiple engines repeat the steps above, one engine at a time. Alterna-

tively, run all engine simultaneously, and divide the ‘Actual amount used’ by the number of
engines. This assumes reasonably even fuel consumption on all engines.

¼ Note: Calibrate option is only available when ‘Set to full’ is selected, and a Fuel Flow is con-

nected and set up as a source.

¼ Note: A maximum of 8 engines is supported using Fuel Flow sensors.

Fuel Level

With the use of a Navico Fluid Level device connected to a suitable tank level sensor, it is
possible to measure the amount of fuel remaining in any equiped tank. The number of tanks
must be set in ‘Vessel Configuration’ to allow discrete tank assignment of the Fluid Level
devices. Under ‘Device list’ on the Network page, view the ‘Device Configuration’ page for each
sensor, and set Tank location, Fluid type, and Tank size.

Refer to the Operator manual on setting up the Instrument bar or a gauge on the Instruments
page using the Fluid Level device data.

¼ Note: A maximum of 5 tanks is supported using Fluid Level devices.

¼ Note: Tank data that is output by a compatible engine gateway can also be displayed, how-

ever tank configuration for such a data source is not possible via the NSS evo2 displays.

Software setup | NSS evo2 Installation Manual

CZone setup

In order to communicate with the CZone modules connected to the network, the NSS evo2
must be assigned a unique CZone Display Dipswitch setting.

The functionality of the CZone system is determined by the CZone Config File (.zcf), which is
stored on all CZone modules and supported Simrad displays, such as the NSS evo2. The file is
created using the CZone Configuration Tool, a specialised PC application available from BEP
Marine Ltd, and associated CZone distributors.

The NSS evo2 system provides a means to load the Config file, as well as apply updates to
module firmware, removing the need to take a laptop computer aboard the vessel.

Enabling CZone functionality

If the Czone device(s) are not automatically detected, it is possible to manually enable CZone.

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
config file 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 config is already available on the network, it will immediately commence
uploading to the NSS evo2 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 first, every time the NSS
evo2 is powered up.

CZone backlight control

Enabling this will cause the NSS evo2 to synchronize its backlight setting with that of any
CZone Display Interfaces set up to share backlight settings.

¼ note: CZone Config also needs to have the NSS evo2 set as a controller.

Import and backup a cong le

The files page may be used to import CZone config files, or export a copy to a Micro SD card.
Importing will overwrite the existing file on the NSS evo2 and all connected CZone devices.

For further information see “Backing up and Importing user data” on page 39

Upgrading module rmware

The files page also allows the loading of CZone module firmware updates. For further
information refer to “NMEA 2000 and Ethernet device upgrades” on page 39

NMEA 0183 setup

The NMEA 0183 port must be set to suit the speed of connected devices, and can be
configured to output only the sentences required by listening devices.

Receive waypoint

Select this option to allow another device capable of creating and exporting waypoints via
NMEA 0183 to transfer directly to the NSS evo2.

Baud rate

This should be set to correspond with devices connected
to the NMEA 0183 input and output. The input and output
(Tx, Rx) use the same baud rate setting.

¼ Note: AIS transponders typically operate at NMEA 0183-HS

(high speed), and will require the baud rate to be set to
38,400.

Serial Output

Selection will determine whether data is output via Tx
lines, and will enable editing of the output sentences list.

Serial Output Sentences

This list allows control over which sentences need to be transmitted to other devices from the
NMEA 0183 port. Due to the limited bandwidth of NMEA 0183 it is desirable to only enable
the data that is required. The less sentences that are selected, the higher the output rate of
the enabled sentences.

Commonly used sentences are enabled by default.

NMEA 0183 over Ethernet

The NMEA 0183 data stream is also output over ethernet, which is made available to tablet
devices and PCs, using the WiFi1 wireless adaptor.

The ethernet dialogue provides IP and port data typically required for configuring the
application on the third party device.

¼ Note: Other MFDs can’t decode this information back to NMEA 0183, to use the data as a

source. To share data a physical NMEA 2000 or NMEA 0183 connection is still required.

| 35

Software setup | NSS evo2 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 evo2 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, as shown below.

The ‘Reset Display List’ can be used to refresh the list of connected displays and their UDB
version.

Databases

The upper table gives an account of the various automatically synchronised databases that
ensure Simrad display units 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 affect databases. When the tick box ‘Dirty’ is ticked, the
unit has identified that its 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 “This display” 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 identified if a display does not show any other IP addresses
than its own.

The ‘UDB version’ is dependant on the software version installed on the display. It will never
change on its 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 “Software updates and data backup” on page 39

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.

FLIR® camera setup

The FLIR M-series cameras are plug and play when used in conjuction with the WiFi-1 acting
as a DHCP host. For setup on networks not utilizing a DHCP host, refer to the Simrad website
www.simrad-yachting.com or contact Simrad technical support.

Software setup | NSS evo2 Installation Manual

Wi setup

The NSS evo2 can be veiwed and controlled via an Android or Apple tablet, using the WiFi1
module and GoFree application. Various 3rd party applications can also use the data stream.

The GoFree application should be downloaded from the Android Play Store, or Apple Store.

Navigate to the wifi network connection page on the tablet, and find the ‘GoFree Wifi xxxx’
network. If more than one is in range, check which unit is wired to your network by viewing
the ‘Access Points’ page on the NSS evo2. Connect to the network using the eight character
password printed on the silver label of the GoFree module, which is also available on the
‘Access Points’ page.

Open the application, the NSS evo2 should be automatically detected. If the NSS evo2 does
not appear, follow on screen instructions. Select graphic icon of display to view - both video
outputs on the NSS evo2 should be available for selection.

The above dialogue will appear on the NSS evo2 display when connection is attempted.
Select ‘Yes’ for one-time connection, or ‘Always’ if device is to be remembered for regular
connection.

Devices

When a wifi device is connected, it should appear in the wifi devices list. Selecting ‘Always
allow’ will mean the device can automatically connect without needing a password each
time. This menu also allows disconnection of devices that no longer require access.

Access Points

This page shows connected GoFree devices, their IP address, and mode.

Mode

When more than one device is connected, only one
may operate as ‘Primary’. Primary mode determines
that the device is acting as DHCP server - only one
DHCP server may exist on a network at a time.

To set a device as secondary, the NSS evo2
must initially be connected to only one GoFree module. Pressing ‘menu’ with the device
highlighted, opens the dialogue that allows setting to secondary. Once completed, a second
module may be plugged in, and will automatically default to primary.

¼ Note: Use of multiple devices is solely for range extension purposes, and is usually only

required on larger vessels.

| 37

Software setup | NSS evo2 Installation Manual

Channel

Channel setting is available in order to
overcome potential interference to the
GoFree device by another RF device
transmitting in the same frequency band.

Advanced

Tools are available within the NSS evo2 software to assist in fault-finding and setting up the
wifi network.

Iperf

Iperf is a commonly used network performance tool. It’s provided for testing Wifi network
performance around the vessel so weak spots or problem areas can be identified. The
application must be installed on and run from the tablet device. The NSS evo2 must be
running Iperf server before initiating the test from the tablet.

Once completed results similar to the following should appear;

On exiting the page, Iperf will automatically stop running.

DHCP Probe

The GoFree Wifi module contains a DHCP server that will allocate IP addresses for all the
MFDs, radars and sonars in a network. If integrating with other devices, such as a 3G modem
or satellite phone, other devices in the network may also be acting as DHCP servers.

To make it easy to find DHCP servers on a network, dhcp_probe may be run from the NSS
evo2, which will show results similar to the following when another dhcp server is found;

38 |

Software setup | NSS evo2 Installation Manual

Only one DHCP device may be operational on the same network at a time. If a second device
is found, turn off it’s DHCP feature if possible. Refer to the device’s own instructions for further
assistance.

¼ Note: Iperf and DHCP Probe are tools provided for diagnostic purposes by users familiar with

network terminology and configuration. Navico is not the original developer of these tools,
and can not provide support related to their use.

Software updates and data backup

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

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

The NSS evo2 may be used to apply software updates to itself, and to supported NMEA 2000
and ethernet devices, with files read off an SD card.

Before initiating an update to the NSS evo2 itself, be sure to back up any potentially valuable
user data.

Backing up and Importing user data

There are two files that can be backed up that relate to user changes made to the system:

• ‘Waypoints, Routes, and Tracks database’

• ‘Settings database’ (includes preferences such as unit settings, custom new pages, and Czone

configuration files)

The backup procedure is similar for both - simply select which you want to backup and select
the destination to save to, e.g. on the unit, or to an SD card.

The user has the option of exporting all waypoints, or exporting only waypoints contained
within a specific region.

Waypoint backup offers different file formats to save as:

• User data file version 5: Use with current Navico MFDs (NSS evo2, NSO evo2, NSS, NSO, NSE,

Zeus, Zeus Touch, HDS Gen2, HDS Gen2 Touch). Offers most detail

• User data file version 4: Use with current Navico MFDs (NSS evo2, NSO evo2, NSS, NSO, NSE,

Zeus, Zeus Touch, HDS Gen2, HDS Gen2 Touch).

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

• User data file 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.

Later, if the NSS evo2 is defaulted or user data is accidentally deleted, simply return to the files
page, highlight the backed up file, and select ‘Import’. View file details for creation date.

NSS evo2 software upgrades

The update file must be loaded to the root directory of an SD card.

In the files menu, locate the update file on the SD card and select ‘Upgrade’. Accept the
prompt to reboot the unit, and wait a few moments as the unit restarts. Do not remove the
SD card or repower the NSS evo2 until the process is completed (this will typically take no
more than a couple of minutes). Backup may also be initiated at boot up - simply insert the
SD card before turning unit on, boot unit, and follow on-screen instructions.

NMEA 2000 and Ethernet device upgrades

The update file must be loaded to the root directory of an SD card.

To update NMEA 2000 and ethernet devices select the ‘upgrade’ option presented when the
file is highlighted. A list should appear displaying any compatible devices the update file
applies to - in most cases this will be a single device. Select device and initiate upgrade. Do
not interrupt the upgrade process.

¼ note: If no device is shown, check device to be updated has power, and run any outstanding

updates for the display first.
