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. 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 sufficient clearance space to connect all relevant cables. For overall width and height requirements, please see the dimensions section on page 52.
3 Mounting the NSS display Panel mount Attach the flush mounting template to the selected mounting position using adhesive tape. Drill pilot holes for the four hole saw cuts and four self tapping screws used to secure the display. If using M4 machine screws use a 5 mm (0.20 ”) drill bit. Use a 25 mm (1 “) hole saw to cut the four corner radius. Cut along the dotted line and remove the shaded area. Peel backing off the gasket and apply to the surface.
Bracket mount Using the bracket as a template, mark places to drill the central cable hole and four pilot holes for the bracket fasteners. Drill cable and fastener pilot holes. screw bracket down with fasteners. Fit rear bezel to NSS using supplied machine screws. Align the NSS ratchet teeth with those of the bracket and partially screw in the bracket knobs one at a time. Further tighten both knobs to ensure the unit is held securely and can’t tilt forward under it’s own weight.
4 Wiring the NSS Wiring guidelines Don’t do this Do this Don’t make sharp bends in the cables Do make drip and service loops Don’t run cables in a way that allows water to Do tie-wrap all cables to keep them secure flow down into the connectors Don’t route the data cables in areas adjacent If cables are shortened, lengthened, or reto radar, transmitter, or large current carrying terminated, do insulate and protect all wiring cables connections Do leave room at the back to install and remove cables !

5 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.
Power Control Master Power Control Slave A B Black Red C Black Red Yellow Yellow Broadband Radar Black Red Yellow + _ 12 - 24 V DC Power Control Bus Power Control Master Display (A) turns on using the power button. It is set as the Power Control Master and will output voltage on the Power Control bus to turn on display (B) and Broadband radar (C).
External alarm Blue wire on power cable: An external alarm can be connected to one or more displays on the network. 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 one display and seen, heard and acknowledged from all displays. How ever the external alarm siren can be enabled or disabled on individual displays.
6 External GPS Mounting location Depending on vessel design and materials, certain mounting locations chosen for the NSS may not offer 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.
7 Echosounder Internal echosounder The NSS7 and NSS8 have an Internal Broadband Echosounder. Navico transducers fitted with the 7 pin blue connector can be plugged directly into the corresponding blue socket adjacent to the power connector. External echosounder An optional Navico external sounder module (eg. BSM-1, BSM-2, StuctureScan HD) can be added to the NSS7, NSS8 and NSS12 via the ethernet port on any of these devices.
Transducer adapter cables For vessels with existing transducers that do not have the Navico blue 7 pin connector, there are two adapter cables available to assist with installation. For vessels that already have a transducer that was used with older Navico products that has 6 pin connector. Use 000-00022-001 6 pin to 7 pin transducer adapter cable. These transducers will require the 10 k temp version of the transducer selected for transducer type in Echo Installation.
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.
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 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.

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 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 insurance purposes.
Sidelobe suppression 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.
9 Video In Connect up to two composite video cameras to each display unit using the optional Video / Data cable. This connects to the VIDEO IN port on the rear of the display. Note: The video images will not be shared with other displays via the network. It is only possible to view video on the unit connected to the video source.
10 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 configured in the software for different baud rates up to 38,400 baud. NMEA 0183 sentences output by the NSS can be individually turned on or off. Refer to “NMEA 0183 supported sentences” on page 61 for a complete list of sentences.
Serial port setup NMEA 0183 setup is done from the Network Settings page. Receive waypoint Select this option to allow device capable of creating and exporting waypoints via NMEA 0183 to transfer directly to the NSS. Serial communication This should be set according to correspond with devices connected to the NMEA 0183 input and output. RS422 is the default setting. The input and output always use the same standard.
NMEA 2000 / SimNet 11 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 specification approved for use in NMEA 2000 certified networks.
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. 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.
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.
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.
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. Network Groups It is also possible to group certain settings so they are duplicated across the network on multiple displays.
12 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. Note: a maximum of two NSS may be connected to the same network.
Expanding the NSS12 With the NSS12, up to three ethernet devices can be connected directly to the unit. If more than three modules need connection, use the optional network expansion port (NEP-2). NSS12 BSM-1 Broadband Radar A second NSS connected to one of the NSS12’s three built in ports will have full visibilty and control over any devices connected to another port on the NSS12, in the same way it would if all devices were connected via an NEP-2 expansion port.
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.
Autopilot 13 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.
Using the SG05 EVC gateway The SG05 is connected to the SimNet network in place of Autopilot computer. It connects to a Volvo Gateway for communication with Volvo’s EVC system. Note: rudder angle data is sourced from the EVC system and a seperate rudder angle indicator is not required.
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.
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.
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.
LUBBER LINE Magnitude of local field in % of earth’s magnetic field. Direction of local field 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 offset parameter so that the bearing to the object and the compass readout becomes equal.
HI-A LO-A HI-M LO-M High response parameters set automatically Low response parameters set automatically High response parameters set manually 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.
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.
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.
14 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.
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 Config File (.zcf ), which is stored on all CZone modules and supported Simrad displays, such as the NSS. The file is created using the CZone Configuration Tool, a specialised PC application available from BEP Marine Ltd, and associated CZone distributors.
Software Updates and Screen Calibration 15 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 fix 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 files read off a Micro SD card.
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 file is highlighted, followed by confirmation of the device you wish to upgrade. Do not interrupt the upgrade process. Touch Screen Calibration 1. Turn the unit off 2. Press and hold the MENU key, then turn the unit on 3.
