A)   Furuno Navnet 3D SYSTEM:

Q1-SYS – How many Furuno Navnet 3D Processors are allowed in one Furuno Navnet 3D network?

A1-SYS –
Any combination of up to 10 MFD Processors are allowed in a Furuno Navnet 3D Network. However, the actual number of displays in the system may be higher if MFDBBs are installed using “Clone” or “Extended” Display Mode. More information about the Clone and Extended Modes for the MFDBB can be found in this document.

Q2-SYS – How many Digital Radar Sensors (DRS) can be installed in one network?


A2-SYS –
Up to two DRS can be installed and controlled in one Furuno Navnet 3D network.

Q3-SYS – How many Fish Finders can be installed in one network?


A3-SYS –
Up to two Network Fish Finders can be installed and controlled in one Furuno Navnet 3D network. For example, both a DFF1 and BBFF3 (or DFF3) may installed on one vessel and the operator may select which one to be enabled as the echo sounder source. This allows the vessel to change geographic regions and instantly select the optimal echo sounder source for a particular fishery.

Q4-SYS – Can I connect multiple position, depth and other data sensors to the system?


A4-SYS –
Multiple sensors of the same or different kinds (i.e. two GPS Sensors) may be connected to any Furuno Navnet 3D network for backup purposes. When multiple sensors providing independent but redundant data are connected, the installer will have to define the primary sensor at the Master MFD during installation. Primary sensor selections are global settings, as they will be used and displayed by all Furuno Navnet 3D MFDs in a network. All other sensors providing the redundant information will be used as “Back-Up” sensors. Furuno Navnet 3D will automatically “Switch” and utilize these back-up sensors in the event that a failure occurs with the primary sensor.

Q5-SYS – What is the Furuno Navnet 3D memory capacity?


A5-SYS –
All Furuno Navnet 3D MFDs and Black Box systems have a ruggedized, shock resistant internal Hard Disk Drive (HDD) with 40 Gigabytes of memory storage capacity.

Q6-SYS – Does the MFD have the capability to convert NMEA2000<-->NMEA0183?

A6-SYS –
The NMEA0183 sentences and NMEA2000 PGNs that are used and accepted in the system can be converted and output with either/both NMEA0183/NMEA2000 format (except forth engine data that is input only). Note that only one type of data can be output at a time (one position, one depth, one heading…). In case of multiple GPS, the position which is output is the one currently used by the display.

Q7-SYS – Can engine data be displayed on the MFD?


A7-SYS –
Yes, certain engine data (up to three engines) in NMEA2000 format is compatible and may be displayed on any Furuno Navnet 3D MFD in the Network. The currently accepted engine data is as follows:

- Engine Parameters (PGN 127488)
Engine Speed

Engine Boost Pressure


- Engine Parameters (PGN 127489)
Engine Oil Pressure

Engine Temp

Engine Temperature Status

Engine Warning Status


Q8-SYS – What is the purpose of Audio In/Out?

A8-SYS –
An analog speaker can be connected to any MFD (for Alarm Output and MP3 Stereo Output). Audio Input is provided for future applications.

Q9-SYS – What is shared on the network?


A9-SYS –
The Furuno Navnet 3D was designed as a network system. Radar, Sounder, IP Camera, Points, Routes, Tracks, Navigation Data, and System Settings are all shared via Ethernet on the Furuno Navnet 3D network.



B)  Furuno Navnet 3D CONNECTIONS:


Q1-CON – Can I connect a mouse to Furuno Navnet 3D?


A1-CON –
A generic USB mouse may be connected to any Furuno Navnet 3D MFD. At this time, some functions such as accessing the menu, changing display modes and scrolling require use of the Furuno Navnet 3D keyboard. Full mouse-based control of Furuno Navnet 3D should be available in summer 2008.

Virtually any "off the shelf" USB mouse (wired or RF wireless but NOT Bluetooth) will work with Power 12/24VDC DVI port, DVI-D/D S-LINK 5/10m Network port, RJ45 19S1181 2/5/10m

Furuno Navnet 3D. However, in order to utilize full RotoKey functionality, you will need a mouse that has a scroll wheel that is also "clickable" with a middle click, which will emulate selection and confirmation of a desired RotoKey function. No loading of additional mouse software is permitted. However, the standard Mouse HID drivers will load automatically, allowing most mice and wireless mice to work fine.


Q2-CON – What is Power Synchronization?

A2-CON –
A Furuno Navnet 3D network is a system in which all components share information (navigation data, settings, points, routes, etc) with each other. To allow proper network synchronization and functionality, the MFDs have a special “sleep mode” that allows each MFD to process data while consuming low power. Furuno Navnet 3D MFDs can be in 3 states:

- ON:
This is the regular mode of operation. The screen is ON and the user can interact with the device. The unit can process and share information on the network.

- OFF:
The MFD is completely OFF and doesn’t process information. No power is consumed in this state.

- Sleep Mode:
The screen is off and no user interaction is possible (except turning the unit ON with the Power Key). Even though the MFD seems to be turned off, it will still process and share information with other MFDs on the network. The MFD consumes lower current in this state. Any sensors attached to the MFD data ports will still function normally. Sleep Mode Functional Description: When the first MFD is powered ON (using the power key), all the other networked MFD(s) automatically start in sleep mode. Using the Power key on an MFD in sleep mode will turn it ON. Using the power key on an MFD that is turned ON will put it in Sleep Mode. Using the Power key on the last MFD turned “ON” on the network (all the others are already in Sleep mode) will turn the system (all the MFDs) completely OFF.

IMPORTANT!!:
Sleep Mode functionality requires the use of Furuno proprietary Hubs. The Internal MFDBB Hub and the optional Furuno HUB101 both provide Furuno Navnet 3D Sleep Mode functionality. Use of other generic Ethernet Hubs/Switches, while allowed, will not work with Furuno Navnet 3D Sleep Mode! Caution must also be used in that only “Two Pair” Ethernet cables may be utilized with generic hubs/switches so that the Sleep Mode signals are not short circuited by “Four Pair” Ethernet cables.

Q3-CON – Can I connect non-Furuno devices to the HUB101 (PC, Sensor…)?

A3-CON –
The Furuno HUB101 has a switch for each Ethernet port that can enable/disable the Power Synchronization function. When connected to an MFD, the switch must be setup to allow the Power Synchronization. When connected to any other device (PC, old generation sensors…) the switch MUST be setup to disable the Power Synchronization to protect other devices (such as PC) from the Power Synchronization signal. Here is a list of all devices that support Power Synchronization: - All Furuno Navnet 3D Displays: MFD8, MFD12, MFDBB and DCU12 - All Furuno Navnet 3D Radar Power Supplies: PSU012 and PSU013 - Sounders: DFF1 and DFF3 - AIS: FA30 and FA50

Q4-CON – Can a generic Ethernet 10/100 Switch be used for Furuno Navnet 3D?


A4-CON –
Yes, a 100Mbps Switch can be used. In this case, “2-pair” Ethernet cables must be used between each MFD and the generic Ethernet Switch so that the Furuno Power Synchronization signal does not interfere with or harm the Ethernet Switch. Failure to do so could damage the switch and any other components connected to it. Note that when a regular switch is used, the Power Synchronization and Sleep Mode will network. The use of the Furuno HUB101 is strongly advised. It will allow power synchronization on the network and protect your equipment such as PC when regular CAT6 (4 pair Ethernet) cable is used.

Q5-CON – How is the BB Keyboard Control Unit (MCU001) connected to the BB
Processor?


A5-CON –
The BB Keyboard is an Ethernet Network Device that is powered directly from the MFDBB via the Ethernet Cable. This is NOT true Power-Over-Ethernet (POE). Standard POE Devices may NOT be directly connected or powered by the internal hub in the MFDBB. Direct connection of the BB Keyboard to the MFDBB allows an easy single standard Ethernet cable connection to the MFDBB Keyboard. The MFDBB Processor Unit (MPU001) contains 4 Ethernet ports. Two of these ports provide special power and are dedicated ONLY for MFDBB Keyboard connections. MFDBB Keyboards must be directly connected to one of the dedicated Ethernet ports on the MFDBB (the Keyboard cannot be connected to a Switch). Note that the supplied Ethernet cable is 5M but other lengths are available.

Q6-CON – Is it possible to connect dual monitors and dual control heads to an MFDBB?

A6-CON –
Yes, the following MFDBB installation configurations are possible. [Single] [Dual station–Clone Mode] [Single station–Extended Mode] When Extended Mode is used (with only one keyboard), the two screens need to be located in close proximity to each other. Dual keyboard installation from one processor requires use of the Monitor “Clone” mode.

Q7-CON – If two monitors with different sizes and different native resolutions are
connected to the MFDBB, what will happen?

A7-CON –
The BB can only output the same resolution to both of its DVI-I ports. Some DVI Monitors have a video scaling feature that allows higher than native resolutions to be displayed. In other cases, it may be necessary to lower the BB resolution so that both monitors will function properly. Each MFDBB System can be selected for either 800x600, 1024x768 or 1280x1024 resolution in DVI and/or VGA Video Output formats. Utilizing the provided VGA signals from each of the two DVI-I Ports on the MFDBB will require a simple DVI-VGA plug adapter or cables. Note: While DVI-I ports, containing both DVI and VGA signals, are available on the MFDBB, the MFD8 and MFD12 only provide a DVI-D video repeater port. This means that a true DVI display must be used if a customer wishes to repeat video from either the MFD8 or MFD12.

Q8-CON – How are NMEA2000 sensors connected?

A8-CON –
Furuno Navnet 3D MFD units have one NMEA2000 connector (Device Net Micro style connector). All DRS radar sensors have one NMEA2000 port (Terminal Block connector). You can directly connect Furuno NMEA2000 sensors to the DRS radar sensor, without having to run another NMEA2000 cable up the mast.

NOTE:
You may ONLY connect one MFD or DRS to the same NMEA2000 Network. Some Furuno Navnet 3D vessels may contain several smaller NMEA2000 Networks where their data is linked via the High-Bandwidth Furuno Navnet 3D Ethernet Network. In these cases, each separate NMEA2000 network will be “Bridged” together via the Furuno Navnet 3D Ethernet Network. Furuno Navnet 3D MFD and DRS NMEA2000 ports shall not be connected together. In the case where NMEA2000 engine data, or other ship’s data, is introduced to the Furuno Navnet 3D Network, the connection is made to only one MFD, and this MFD will bridge the data to other MFDs in the network.

Q9-CON – Is it possible to terminate an NMEA2000 bus in the DRS?

A9-CON –
A termination resistor is provided with each DRS. In most cases, this resistor will be required when connecting one or two Furuno NMEA2000 Devices to the DRS. It must be inserted into the appropriate NMEA2000 terminals inside the DRS while installing the system.

Q10-CON – How many Furuno NMEA2000 sensors can be connected directly to a DRS?


A10-CON –
The total number of Furuno NMEA2000 sensors that can be connected is dependent upon on the sum of their power consumption. The DRS can supply a maximum of one ampere to the connected NMEA2000 Sensors.

Q11-CON – Is the NMEA2000 port on the DRS a standard NMEA2000 Port?


A11-CON –
Technically the answer is NO, only Furuno, or Furuno approved, NMEA2000 products may be connected to the NMEA2000 Port on a DRS. Memory limitations do not allow the DRS to support every NMEA2000 PGN, especially proprietary PGNs that may be required to program and configure other manufacturer’s sensors. The DRS NMEA2000 Port will be directly compatible with various Furuno NMEA2000 sensor products like GPS, Satellite Compass, and weather stations.

Q12-CON – Does the DRS need to be turned “ON” for the NMEA2000 data port to be active?


A12-CON –
Power needs to be supplied to the DRS in order for the NMEA2000 information to be processed. This will occur if any MFD supplying power to the DRS is either in “Sleep Mode” or in the normal power “ON” state as described earlier. Of course, the DRS may be in either Transmit or Standby modes of operation.

Q13-CON – How many NMEA0183 ports are provided on every Furuno Navnet 3D MFD?

A13-CON –
Each Furuno Navnet 3D MFD has three full NMEA0183 I/O ports. One is located in a dedicated MJ7 connector. This is identical to the NavNet 1/vx2 “DATA1” port and allows direct connection of a Furuno BBWGPS or 0183 Smart Depth sensor. The others are located in a single 18 pin connector. A 2 meter “Pig-Tail” cable is supplied as standard with each MFD. Each 0183 I/O port can accept baud rates from 4800 up to 38.4Kbps and output strings are independently programmable for each port.

Q14-CON – What type of heading inputs are supported by Furuno Navnet 3D?
A14-CON –
Only NMEA heading (NMEA0183 or MEA2000) can be connected to a Furuno Navnet 3D MFD or DRS. Furuno proprietary AD10 (4-wire Clock and Data) protocol is no longer supported. Heading input to Furuno Navnet 3D will allow functions such as Radar Overlay, North Up in Radar and heading stabilization to work correctly. The NMEA0183 heading refresh rate needs to be 100ms (or faster) in order for the DRS ARPA to function! If the DRS ARPA feature is not required, a refresh rate of heading information can be 200ms (5 times per second). Furuno Navnet 3D will reject 0183 Heading Information if refresh rate is limited to only once or twice per second. NMEA0183 heading can be accepted on any NMEA port at a baud rate up to 38.4kbps. Heading coming from NMEA2000 sensors will always be at the correct speed for ARPA function. Example of connection with PG500 and NavPilot:


C)  Furuno Navnet 3D COMPATIBILITY:


Q1-COMP – Are NavNet 1/vx2 systems compatible with Furuno Navnet 3D?


A1-COMP –
Furuno Navnet 3D has limited compatibility with certain Furuno NMEA0183 and Ethernet sensors that may be part of an existing NavNet 1/vx2 System. Some of these are the BBGPS, BBWGPS, BBFF1, BBFF3, BBWX1, FAX30 and most existing transducers. However, because Furuno Navnet 3D is based on new technology, there is no network compatibility between NavNet 1/vx2 processors/radars and Furuno Navnet 3D MFDs. Further, Furuno Navnet 3D and NavNet 1/vx2 displays (processors) cannot exist on the same Ethernet Network. Only NavNet 1/vx2 NMEA0183 serial outputs may be used to interconnect NavNet 1/vx2 to Furuno Navnet 3D MFDs.

Q2-COMP – Is the FAX30 compatible with Furuno Navnet 3D?


A2-COMP –
Yes, it is compatible with Furuno Navnet 3D.

Q3-COMP – Is the FA30 compatible with Furuno Navnet 3D?


A3-COMP –
Yes, it is compatible with Furuno Navnet 3D.

Q4-COMP – Is the FA150 compatible with Furuno Navnet 3D?


A4-COMP –
Yes, a serial NMEA0183 connection at 38.4kb should be used.

Q5-COMP – Can an AIS receiver other than Furuno be used for Furuno Navnet 3D?

A5-COMP –
Yes, any AIS receiver that outputs VDM strings (NMEA0183) at a data rate of 38.4kbps can be connected using one of the 3 NMEA inputs on a Furuno Navnet 3D MFD.

Q6-COMP – Can vx2 network cable be used for Furuno Navnet 3D?

A6-COMP –
No, only RJ45 style connector cables are used for Furuno Navnet 3D instead of the old NavNet 1/vx2 6-pin round connector cable.

Q7-COMP – How can I use weather data from MaxSea on a Furuno Navnet 3D MFD?

A7-COMP –
NavNet 3D products cannot be connected directly to the Internet. Worldwide weather will be available in late 2008, using a separate PC that will download the weather data (GRIB file).

Q8-COMP – Is the BBWX1 Sirius Satellite Weather Module compatible with Furuno Navnet 3D?


A8-COMP –
Yes, the BBWX1 receiver currently offered is compatible with Furuno Navnet 3D.

Q9-COMP – Can an FAR2xx7 radar be connected to Furuno Navnet 3D?


A9-COMP –
FAR2xx7 connectivity is foreseen in a future software release of Furuno Navnet 3D. No firm schedule is available at this time.

Q10-COMP – Can a Furuno Navnet 3D DRS be used by an FAR2xx7 IMO radar processor?


A10-COMP –
No, FAR2xx7 processors cannot display the radar echo from a Furuno Navnet 3D DRS sensor. However, FAR2xx7 Radar control and display capability is planned for Furuno Navnet 3D. D. CHARTS



D)   Furuno Charts

Q1-CHART – Are current NavNet vx2 CMAP or Navionics Charts compatible with Furuno Navnet 3D?


A1-CHART –
No, however, Furuno Navnet 3D is preloaded with the entire U.S. NOAA Raster (RNC), Vector (S57-ENC), and Bathymetric Database. Free high resolution satellite photos will be available for the USA coastline as well. Note that it is not possible to preload all satellite photos, due to their large file sizes. The dealer or end user will have to install specific satellite photo areas on the internal Hard-Drive. For areas outside of the U.S., a worldwide portfolio of MapMedia Charts will be available for purchase with Furuno Navnet 3D Systems. These MapMedia charts (MM3D) will be available in Raster and/or Vector Formats. Most Vector Format MapMedia charts will be based on Navionics Database information. It is very important to note that this Navionics vector data will be converted into MapMedia “MM3D” format for use with Furuno Navnet 3D. Therefore, Navionics Chart products such as Platinum, Silver, and Classic are NOT compatible with Furuno Navnet 3D. In summary, all Furuno Navnet 3D Chart Data must originate from MapMedia in the “MM3D” format.

Q2-CHART – Which charts come preloaded in Furuno Navnet 3D systems supplied in North America?

A2-CHART –
All Furuno Navnet 3D MFDs come pre-loaded with Raster charts, Vector charts and Bathymetric Data (3D), covering the USA coastline, including Alaska and Hawaii. The Raster charts come from the official NOAA raster chart library that has been converted to the TimeZero compatible format. The Vector chart data comes from the official NOAA S57 chart library that has been converted to the TimeZero compatible format. The Satellite Photo areas do not come preloaded; however, they will be available at no cost (other than shipping, handling and storage media – i.e. SD Card or CD). Users will be able to install several Satellite Photo Areas on the Furuno Navnet 3D hard drive.

Q3-CHART – What is the chart coverage in the USA?

A3-CHART –
The Raster Chart coverage is complete (equivalent to more than 1000 paper charts), including Alaska and Hawaii. Vector Charts Coverage (S57) currently includes most of U.S. Areas (NOAA advises that they have converted approx. 80% of all their detailed raster charts) NOAA adds and updates Vector and Raster charts daily! Users will be able to update their Furuno Navnet 3D charts on www.navnet.com as often as desired. See below for the Satellite Photo coverage.

Q4-CHART – Can I directly load NOAA charts from the NOAA www site?

A4-CHART –
No, not directly. Furuno Navnet 3D can only display MapMedia charts in MM3D format. For the USA, the MapMedia chart data comes from the NOAA BSB raster chart and S57 vector chart library. Customers will be able to update their Furuno Navnet 3D charts online at the www.navnet.com site, using an SD Card and a PC connected to Internet. The stored Furuno Navnet 3D charts can be updated as frequently as the customer desires. A new Chart Update service will be provided free of charge during the first year of ownership. This service is only available for the Raster and Vector charts in the USA.

Q5-CHART – Can I update charts outside the USA?

A5-CHART –
At this time, online updates from www.navnet.com are not planned for regions outside the USA. Customers will be able to update their charts by purchasing a new SD Card through a Furuno dealer, at a discounted price.

Q6-CHART – What is the chart coverage outside the USA?

A6-CHART –
Vector chart data outside the U.S. will primarily be derived from the Navionics Gold (“XL3”) database and thus will have the same coverage. Raster chart data outside the U.S. will be derived from MapMedia MM2 database and thus will have the same coverage. The MapMedia Catalog is available at: http://comen.maxsea.fr/MaxSea/Charts/MapMedia/MapMediaCatalog/default.aspx

A complete MM3D chart catalog will be available on
www.navnet.com when Furuno Navnet 3D is released.

Q7-CHART – How are the charts installed in Furuno Navnet 3D?

A7-CHART –
Charts outside the USA will be installed on the system using SD-Cards. The Charts will be copied (transferred from the SD-Card to the internal memory) allowing the user to install multiple areas at the same time. When the installation is done, the SD-Cards can be removed and stored safely for backup. When a chart is installed, an unlock code is required to view the chart.


E)  Furuno Navnet 3D PLOTTER

Q1-PLOT – What is the “Ghost Cursor”?

A1-PLOT –
The cursor movement is synchronized between radar and plotter screens when displaying both radar and plotter screens. Heading data is required to enable this function.

Q2-PLOT – What is the Minimum/Maximum Zoom Scale?


A2-PLOT –
20 feet to 3,000 nm, horizontally across the full MFD display.

Q3-PLOT – How many points (waypoints/marks) can be stored in a Furuno Navnet 3D MFD?

A3-PLOT –
Up to 2,000 points at a time. An end-user can use files on SD cards to store an unlimited amount of additional points.

Q4-PLOT – How many points for ship's tracks?

A4-PLOT –
Memory for ship's track is fixed to 12,000 points. Once the points reach the maximum, the oldest data will be replaced by the new data (Circular Buffer). The ship's track displayed can be saved in Furuno Navnet 3D memory and/or on SD cards to store or backup an unlimited amount of additional track points.

Q5-PLOT – How many routes can be stored?


A5-PLOT –
Up to 200 routes with up to 100 points per route. Furuno Navnet 3D Internal Memory Route Storage is limited to 2,000 points. An end-user can use files on SD cards to store an unlimited amount of additional routes and points.

Q6-PLOT – Is Heading used in the Furuno Navnet 3D Plotter Modes?


A6-PLOT –
Yes, unlike NavNet 1/vx2, which only uses GPS COG for vessel alignment, if provided, Furuno Navnet 3D will use Heading information to orient the boat icon. Additionally, a useful heading line can be enabled in the plotter mode as well.

Q7-PLOT – Is PBG (Personal Bathymetric Generator) available on Furuno Navnet 3D?

A7-PLOT –
At this time, the PBG feature is not planned for Furuno Navnet 3D MFDs. To use this function, the user will have to connect a PC loaded with MaxSea Marine Software to the Furuno Navnet 3D network.


F)  RADAR – Digital Radar Sensors (DRS)

Q1-RADAR – Do all Furuno Navnet 3D DRS products have High Speed antenna capability?

Q1-RADAR –
Yes, all DRS antennas, Domes and Open Arrays, automatically increase in speed from 24 to 36 to 48 rpm as range is decreased, and depending on the radar range 14 selected. When the Radar is used in Dual Range, the antenna rotation is fixed at 24RPM. The antenna rotation speed can also be fixed at 24rpm for all modes/ranges if desired.

Q2-RADAR – What are the changes in the DRS AUTO performance?


Q2-RADAR –
The AUTO clutter controls for Gain, Rain and Sea are dramatically improved; for normal operation, it should no longer be necessary to manually adjust the DRS Radar Image setting from the default AUTO modes in most conditions.

Q3-RADAR – Is the ARPA function an option, as it was with older NavNet Systems?


A3-RADAR –
NO, every DRS radar sensor includes a “Built-In” 30 Target ARPA! ARPA functionality does still require input of stabilized heading data.

Q4-RADAR – Is GPS COG information allowed for Heading and ARPA capability?


A4-RADAR –
No, while some competitor’s radar systems allow GPS COG for Heading and
ARPA functionality, Furuno believes that this capability is dangerous and not reliable, especially for ARPA calculations. Furuno Navnet 3D systems require actual Heading information at appropriate data rates for these functions.


Q5-RADAR – Do Furuno Navnet 3D DRS products all have Dual Range antenna capability?

A5-RADAR –
All DRS antennas, Dome and Open Arrays have “True” Dual Range radar capability which provides “simultaneous” transmission of both short and long pulse. This allows complete independent control of range, gain, sea clutter and rain clutter for two separate ranges on each MFD. This is a very useful and powerful feature.

Q6-RADAR – What is “TimeZero Radar”?

A6-RADAR –
On the MFDBB, the radar picture is displayed using “TimeZero” technology. This allows seamless zooming and offset. Additionally, the radar picture is stabilized with a new process, thus completely removing all smearing effect.

Q7-RADAR – How does Radar Overlay function?

A7-RADAR –
The radar overlay is no longer a dedicated mode. Overlay is part of the Plotter and thus can be used with Raster Charts, Vector Charts, Weather and Satellite Pictures in 2D as well as in 3D. Radar overlay requires a Heading Sensor such as SC30 or PG500.


G)  Furuno Navnet 3D Fishfinders

Q1-SOUNDER – What is the new Airmar Transducer ID function available with Furuno Navnet 3D and the DFF1 and DFF3?


A1-SOUNDER –
This feature enables compatible transducers to transmit important data to the DFF1 or DFF3 (coming mid-2008), including transducer model, functions, frequency, power rating, beam pattern, impedance, ceramic element configuration and acoustic window material. Through this Transducer ID feature, the DFF1 and DFF3 Sounder Modules will automatically know the connected transducer’s precise frequency, operating power and impedance, so it can “tune” its operation to automatically adjust and optimize echo sounder performance.

Q2-SOUNDER – What do I need to utilize the new Heaving Compensation feature, and what does it provide?

A2-SOUNDER –
Echo Sounder Heaving Compensation is a revolutionary new feature available in Furuno Navnet 3D! Heaving Compensation automatically removes vessel motion from the echo sounder display in rough seas. This is usually seen as a “Saw Tooth” distortion of the bottom image due to vertical vessel motion even though the bottom is actually flat. It greatly enhances bottom fishing and bottom trend analysis without sacrificing critical details as can occur when using a traditional Bottom Lock Echo Sounder Mode. In order to utilize this new Heaving Compensation feature with Furuno Navnet 3D, you need to use the DFF1 or DFF3 with a Furuno SC30, SC50 or SC110 satellite compass. Only these satellite compass products can provide vertical vessel motion information to remove this distortion.


H)  Furuno Navnet 3D Camera and Video  Interface

Q1-CAM – What types of IP Cameras can be connected to Furuno Navnet 3D systems?

A1-CAM –
Only AXIS IP Cameras (www.psicompany.com/axis-communications/) that support MPEG4 Video are compatible with Furuno Navnet 3D, as a networkable video source. Certain Axis PTZ (Pan-Tilt-Zoom) IP Cameras may also be controlled with Furuno Navnet 3D Systems for features such as pan, tilt, and zooming. Furuno recommends utilizing AXIS POE (Power Over Ethernet) compatible IP Cameras with a separate POE Ethernet Switch to provide power and Ethernet to each AXIS IP Camera with a single cable. Then, utilize a non-POE port on this switch to link the IP Cameras to a HUB101 in a Furuno Navnet 3D Network. Examples: Fixed Indoor IP Camera: AXIS 207 (approx. $300) Pan/Tilt/Zoom Indoor POE IP Camera: AXIS 212 PTZ (approx. $700) Note: The AXIS 206 is NOT compatible with Furuno Navnet 3D systems.

Q2-CAM – How many IP Camera and analog video inputs are available?


A2-CAM –
Up to four IP Cameras can be networked. Two composite inputs for MFD8/MFD12 (RCA connector) and four for MFDBB (BNC connector) are also available. Furuno Navnet 3D supports PAL and NTSC composite video signals and automatically adjusts for either input. 16

Q3-CAM – Can the analog video input be distributed in a network?


A3-CAM –
No. Unlike video from an IP camera, analog video can be seen only on the MFD that receives the composite video signal. When network IP Cameras (AXIS) are used, any MFD connected to the network can view the picture.

Q4-CAM – What is the video output of the MFDs?


A4-CAM –
The MFD8 has a 640x480 DVI-D output. The MFD12 has an 800x600 DVI-D output. The MFDBB has DVI-I output (800x600 up to 1280x1024).
