Position Fix is differentially corrected using RTCM corrections from beacon stations. This is the normal operating condition. Position accuracy is less than 2 meters.
Position Fix is augmented using the WAAS signal correction. Position accuracy is less than 5 meters.
GPS Position fix is good but the RTCM correction signal is temporarily not available. When DGPS mode menu is set to either Beacon or WAAS.
Good GPS position fix indication when GN70 is operated in autonomous GPS only mode DGPS mode setting is OFF.
RAIM Status
RAIM (Receiver Autonomous Integrity Monitoring) is a fault-detection feature required by
IMO for type-approved GPS units. It is another layer of safety that alerts the operator that a condition may exists in the GPS positioning solution that reduces the desired accuracy of the ship’s position. This feature requires at least five GPS satellites to operate properly, four satellites or less will indicate a RAIM caution condition (R?). If the statistical RAIM error exceeds a specified limit (100 meters-default) a RAIM Unsafe (R-) alarm will be indicated.
This means that the RAIM estimated position error is equal or greater than the preset limit.
The operator is advised to take extra precautionary measures when using the navigation solution until the RAIM indicator switches to RAIM safe (R+) condition.

System Configuration
General
When the GN70 system installation is completed or when the unit is restored to the default settings, a simple network configuration to select the data source is needed. This can be done during the initial turn on. A series of dialog boxes will prompt you through the setup process. Answering yes by pressing the
ENT
key will initiate the auto selection of the antenna unit. Failure in setting up the GN70 correctly will prohibit the navigation system from functioning properly.
For installation with more than one display or more than one antenna unit, some setup is required to assign an antenna to a display unit. This section will help you perform the proper setup.
The Quick Menu Dialog and Submenus
The network configuration settings can be accessed through the quick menu or through the Tools and Settings, then Network submenu. This dialog is accessed by pressing the
MENU
key then selecting Data sources menu or by highlighting the Tools and Settings and then select the Network
22 |
Network Settings
Setup and selection of sources can also be done in the Network menu.
Selecting Data Sources
A data source can be a sensor or a device connected to the network, providing data to other devices. Data can be of different type such as position data, compass data, depth data, etc.
Source selection is required on initial start up of the system with multiple devices, if any part of the CAN bus network has been changed or replaced, or if an alternative source is made available for a given data type and this source has not been selected automatically.
At the first time turn on of a group of SimNet interconnected products, data sources are automatically selected from an internal SimNet priority list. If a data source is connected to SimNet after the first time turn on, this will be identified and automatically selected if no other data source already is selected for the given data type.
You can let the system automatically select your sources, or set up each source manually as described below.
Auto Select
The Auto Select option will look for all SimNet sources connected to the network. If more than one source is available for each data type, the system will automatically select from an internal priority list.
The Auto select function is mainly for situations where the automatic source selection needs to be updated because a selected data source is not supplying data or has been physically replaced with another one. The update secures that the existing source selections are valid and maintained. Missing sources are either automatically exchanged with an alternative source from the list of available sources for the given data type, or the replacing source is selected.
System Configuration | GN70 Operator and Installation Manual
Manual Source Selection
You can manually select the preferred source. This is useful if you have more than one of the same type of device (i.e. multiple GPS antenna units) on the network.
Available sources are listed as shown in the example below. You select active source by ticking the preferred unit. Each GS70 antenna is noted with a serial number (i.e. 100E32#).
Group selection
The GN70 can use GPS antennas or data sources that all other products on the N2K network use, or you may select individual sources for the GN70 system.
If the group is set to “Simrad”, any changes to a source will also affect other display systems on the network.
If the group is “None”, the selected source will be used for that particular GN70 unit only.
Advanced selection
Allows the automatic selection of sources available on the network.

From the device list you can:
-
List all of the active SimNet and NMEA 2000 devices on the network, showing model description and serial number. Devices can be sorted by model ID or by serial number

SimNet Groups
The SimNet Group function is used to control parameter settings, either globally or in groups of units. The function is used on larger vessels where several SimNet units are connected via the network. By assigning several units to the same group, a parameter update on one unit will have the same effect on the rest of the group members.
The illustration below shows a network of three GN70 units (two on the bridge and one in the remote area). The two units on the bridge can be made to belong to one group

HS70/HS80/MX575C D/GPS Compass Antenna Offset
The difference between the compass lubber line and the boat’s center line should be compensated for. This can be done in two ways, namely: physically rotating the compass antenna so the heading is corrected or by entering an offset value using the procedure below. This offset value is saved in the antenna unit.
Entering heading offset procedure:
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

The number of NMEA 0183 messages that can be save in the memory of the MX610JB junction box is eight (8) NMEA sentences per port. If this is exceeded, the NMEA 0183 messages will still be transmitted, however, when the power is turned off in the junction box, only the first 8 sentences will be saved. The 9th and higher sentences will not be available next time the power is turned on.
2.
When a NMEA 0183 smart antenna is connected to the junction box (i.e. MX521A or
MX575C), ports 3 and 4 will be used for this connection. These ports will be grayed out and will not be usable for NMEA 0183 output.

Navigation Method
Different methods are available for calculating the distance and bearing between any two points on a chart.
The Great Circle (GC) route is the shortest path between two points. However, if you are to travel along such a route, it would be difficult to steer manually as the heading would constantly be changing (except in the case of due north, south, or along the equator).
Rhumb lines (RL) are tracks of constant bearing. It is possible to travel between two locations using Rhumb line computation, but the distance would usually be greater than if
Great Circle is used.
Steering Alarm Limits
Arrival Radius
Sets an invisible circle around the destination waypoint.
The vessel is considered to have arrived at the waypoint when it is within this radius.
Off Course (XTE) Limit
This parameter defines the vessel’s accepted offset distance from the leg. If the vessel goes beyond this limit an alarm will be activated.
Arrival Alarm
When the arrival alarm is enabled, an alarm will be activated as the vessel reaches the waypoint or when it is within the specified arrival radius.
Magnetic Variation
Magnetic variation is the difference between true bearings and magnetic bearings, caused by different location of the Geographic and the Magnetic north poles. Any local anomalies such as iron deposits might also affect the magnetic bearings.
Magnetic variation is applied in order to navigate with heading in “True” mode.
When set to Auto, the system automatically converts magnetic north to true north. Select manual mode if you need to enter your own local magnetic variation.
Datum
Most paper charts are made in the WGS84 format, which also is used by the GN70 system.
If your paper charts are in a different format, you can change the datum setting accordingly to match your paper chart.
Coordinate System
Several coordinate systems can be used to control the format for Lat/Long coordinates displayed on the POS and PLOT panels.

Using AIS (PLOT)
If a SIMRAD AIS transponder or DSC transceiver device is connected to the NMEA 2000 network, the GN70 can display the AIS target information in the AIS page. You can also see messages and position for DSC transmitting devices within range. If none is available, the plotter screen can show the waypoints, routes and tracks. You can zoom out by turning the rotary knob counter-clockwise and zoom in by turning it in clockwise direction. AIS targets can be displayed as overlay on the plotter screen. This feature is an important tool for safe travelling and collision avoidance.
You can define alarms to notify you if an AIS target gets too close or if the target is lost.

Your vessel’s MMSI number
You need to have your own MMSI (Maritime Mobile Service Identity) number entered in the GN70 system to be able to receive addressed messages from AIS and DSC vessels.
It is also important to have the MMSI number entered to avoid seeing your own vessel as an AIS target on the plotter.
¼
Note:
The Vessel message option in the alarm settings must be toggled on if any MMSI message shall be displayed.
Filtering the targets
All targets are by default shown on the display if an AIS device is connected to the N2K network.
You can select not to show any targets, or to filter the icons based on security settings, distance and vessel speed.
The vessels extension lines
The length of the extension lines for your vessel and for other vessels can be set by the operator.
The length of the extension lines is either set as a fixed distance, or to indicate the distance the vessel will move to in the selected time period.
COG
Heading
For your vessel, heading information is read from active heading sensor, and COG information is received from the active
GPS.
For other vessels COG data is included in the message received from the AIS system.
Defining dangerous vessels
You can define an invisible guard zone around your vessel. When a target comes within this distance from your vessel, the symbol will change to the
“dangerous” target symbol. An alarm will be triggered if activated in the Alarm settings panel.
Speed and Course indication
The extension line can be used to indicate speed and course for targets; either as absolute
(true) motion in the chart or relative to your vessel.

Maintenance
Preventive maintenance
The GN70 display and antenna unit does not contain any field serviceable components, therefore the operator is required to perform only a very limited amount of preventative maintenance.
It is recommended that you use an optional protective sun cover when the display 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 anti-glare layer, plastics bezel, or rubber keys.
To prevent UV damage to the plastic bezel and rubber keys, it is recommended that sun cover be fitted when the unit is not in use for an extended period.
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.
Trouble shooting
Failure
Unit fails to turn ON
Corrective action
Make sure the power cable is plugged in to the back of the GN70 and the 12-24 VDC power is turned ON. The unit normally takes about 30 seconds to re-boot when power connection is removed and re-connected.
Check the in-line fuse (or circuit-breaker) of the power cable. Replace the fuse when blown.
Using a voltmeter, verify that the 12-24 VDC supply is present on the power cable connector pins.
If problem persist, replace the GN70 unit.
Unit fails to detect the antenna Make sure the GS70 (or any N2K GPS sensor) antenna is connected properly and the cable connector is good. Check for any damage to the cable.
Verify if the dedicated 12 VDC supply to the N2K network is available. Re-cycle the power to the N2K bus.
Verify if the antenna is selected as the source of data under the main Menu/Network page.
Make sure N2K terminators are used on both ends of the NMEA 2000 bus.
If problem persist, replace the antenna unit.

Mounting
General
The standard mounting of the GN70 display is in-dash or panel mount. If there is a need to bracket mount the unit, an optional U-bracket assembly can be ordered separately.
Mounting location
The GN70 unit should be mounted with special regard to the unit’s easy access for operation and maintenance, environmental protection, temperature range, cable connection and cable length.
Survey the front and back side of the instrument panel where the unit will be mounted before cutting the mounting hole to make sure there is ample room around the unit and no hidden electrical wires or other parts will be damaged behind the panel. The panel mounting surface must be flat and even to within 0.5 mm.
The GN70 conforms to the appropriate Electromagnetic Compatibility (EMC) standards, but proper installation is required to get best use and performance from this product.
Ensure adequate separation from other on-board electronics and electrical equipment.
GN70 control unit
Avoid mounting the GN70 control unit where it is easily exposed to sunlight, as this will shorten the lifetime of the display. If this is not possible, make sure the unit is always covered with the optional protective cover when not in use.

GN70 antennas
Several IMO-compliant antenna models can be used with the GN70, namely:
• GS70 - GPS/WAAS smart antenna (N2K interface) - Standard
• HS80 or MX575C D/GPS compass unit (N2K or NMEA 0183 interface) - Option
• MX521A - GPS/DGPS smart antenna (NMEA 0183 interface) - Option
As a general rule, the antenna unit must be located in the open where it will have a good view of the sky aournd it. It must also be located away from large metal objects that can block the GPS signal as well as influence the operation of the antenna unit.
Antenna mounting guidelines
• Install the antenna where it has a clear view of the sky around it
• Keep it away from large metal structures like the main mast or overhead railings
• Stay away from high-powered transmitter antennas like SSB, VHF and other radio transmitter antennas
• Mount the GPS antenna low to avoid excessive position and speed errors while underway
• Locate the antenna at least 10 meters away and below the transmitting beam of the radar and INMARSAT antennas.
Mounting | GN70 Operator and Installation Manual
| 57
MX610 JB junction box (option)
The mounting location must allow for required working area when connecting the cables.
Also ensure that the location for the computer units allows viewing the board’s LED indicators.
The mounting surface needs to be structurally strong, with as little vibration as possible. If possible, mount the unit close to the edges of a panel to minimize vibration.
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. Ensure that there are no hidden electrical wires or other parts behind the panel.
Preferably mount the junction box with the cable entries exiting downwards.
Mount the cable retainer included with the MX610 J-Box on the wall beneath the unit.

Wiring
Wiring guidelines
The CAN network cables and other signal cables (i.e. antenna, compass, NMEA) should not be run in parallel with other cables carrying radio frequency or high current, such as VHF and SSB transmitters, battery chargers/generators, and winches.
Don’t make sharp bends in the cables, and avoid running cables in a way that allows water to flow down into the connectors. If required, make drip and service loops.
If cables are shortened, lengthened or re-terminated, do insulate and protect all wiring connections.
Most of the units are communicating on the CAN bus with drop cables. Try mounting the units within the standard cable length supplied with each unit. Additional cables and cable extensions are available from our distributors.
Warning:
Before starting the installation, be sure to turn electrical power off. If power is left on or turned on during the installation, fire, electrical shock, or other serious injury may occur. Be sure that the voltage of the power supply is compatible with the spec for the units!
The GN70 navigation system; basic wiring principles
The GN70 navigation system use a CAN bus backbone which makes it simple to interface to SimNet and NMEA 2000 (N2K) devices.
NMEA 0183 devices such as autopilots, radar and PC-based ECDIS can be interfaced using the optional MX610JB smart junction box. The 12-Volt DC power to the CAN bus can be supplied through a T-Connector.
In systems with the optional MX610JB junction box the CAN bus is powered by the junction box. The GN70 model have separate power supply cable and can be wired directly to
12-24 VDC. Other SimNet/NMEA devices are powered by the CAN bus.
The following sections describe installation of the components listed in the illustration below. Refer to separate manuals for detailed information about each interfacing unit.
GN70 basic wiring diagram

The CAN bus
The CAN bus is based on the well known SimNet plug & play concept and on the NMEA
2000 (N2K) SAE J1939 protocol. Hard wiring is based on standard NMEA 2000 cables with
Micro-C type connectors and joiners.
The bus consists of a linear backbone using drop cables and Micro-C T-joiners for connecting NMEA 2000 and SimNet devices.
The bus has a maximum cable length of 150 m (500 ft), and a drop cable has a maximum length of 6 m (20 ft).
In a default GN70 system the CAN bus backbone expands from the MX610JB, which supplies power to the backbone. There will always be a female connector in the expanding end of the backbone cables.

Note:
If cables are not supplied by Simrad, ensure that they meet NMEA 2000/IEC61162-1/2 requirements.
Planning and installing a network backbone
• Plan the network carefully
-
It is recommended to create a diagram of the network prior to starting the installation
• Run the backbone between the locations of all CAN devices you want to install
-
It must be less than 6 m (20 ft) cable run from a device to the backbone
• Consider the load/current draw from the devices
For details on network cables and components, refer to our websites: pro.simrad-yachting.com and www.simrad-yachting.com
Terminating the CAN bus
The CAN bus must have a 120 Ohm terminator at each end of the backbone.
In a default GN70 system the CAN bus can be powered and terminated from the junction box PCB, enabled by the micro switch.
Wiring | GN70 Operator and Installation Manual
-
Set the switch to ON when the MX610JB board is at the end of the CAN bus
-
Set the switch to OFF when the MX610JB board is used as additional power supply to the CAN bus which already has correct termination.
Factory default setting of MX610JB terminator is OFF.
For location of the dip switch, refer to the illustrations inside the computer unit.
A terminator in the other end of the CAN bus can be one of the following:
• A power cable with built in terminator (plug marked 120 ohm)
• A single terminator plug (marked 120 ohm)
Shield connection
It is required to use shielded cables to meet radio frequency interference requirements as defined in the NMEA 2000 specification:
• The shield shall not be electrically connected within the interface to the electronic device chassis or ground
• The shield shall be electrically continuous through the network connection
• The shield shall be connected to ground at a single point, normally the ship’s ground at the source of network power
Power supply
¼
Note:
Wheelmark/US Coast Guard approved systems require a Power Failure alarm. In such installations the GN70 and the MX610JB must be connected to different independent power supplies.

It is recommended to install an external on/off switch or circuit breaker for the
Junction Box power supply.
¼
Note:
Do not connect the power cable to the same terminals as the start batteries, drive units, thruster or other high current products
¼
Note:
If joining to an existing NMEA 2000 network or similar CAN bus network that has its own power supply, use an NMEA 2000 Gateway to isolate the two power supplies.
Powering the CAN (N2K) bus
For larger systems additional power should be added at a central point in the backbone to balance the voltage drop of the network. Additional power may be supplied by using an
MX610JB junction box or through a Micro T-Joiner.

NMEA 2000 and SimNet devices
NMEA 2000 devices can be connected to the CAN bus providing they are NMEA 2000 certified, meet the CE, FCC regulations and do not exceed the load specification.
NMEA 2000 devices and SimNet devices with Micro-C connectors connects directly to the
CAN bus backbone using drop cables and Micro-C T-joiners.
¼
Note:
It is recommended to use a gateway when connecting non-Simrad units to the CAN bus backbone.
Devices with SimNet connectors only must be connected using a SimNet to Micro-C adapter cable.
SimNet System
IEC61162-1/2 (NMEA 0183) Devices
