Section 1 - Explanation of the NavNet Concept
NavNet (Furuno Navigation Network) products are the first Furuno products that utilize
TCP/IP protocol over standard 10BASE-T Ethernet to share radar/chart/sounder images
and other navigation information from devices connected within a networked system. In
any single NavNet, a combination of up to five Furuno NavNet Network Components may
be connected to each other(Up to Four Displays and One Network Sounder). All NavNet
Network Components have one integrated 10BASE-T Ethernet port. Each NavNet
Network Component utilizes a Furuno 6-pin waterproof plug for its Ethernet connection.
Defining NavNet Network Components
NavNet Network Components Non-NavNet Network Components
-Any NavNet Display -GPS Sensors
-Network Sounder (BBFF1) -Heading Sensors
-Smart Temp/Depth Sensors
-RD30 Displays
Any NavNet Radar/Plotter or Plotter may be used independently as a stand-alone
product! Additionally, it may be connected to any other NavNet Display or Network
Sounder to form a sophisticated navigation system. If only two NavNet Network
Components are connected together, a single bi-directional cable can be inserted
between them to establish full network communication via their Ethernet ports. However,
if three, four, or five NavNet Network Components are networked together, an Ethernet
Hub must be utilized.
-Up to 5 NavNet Network Components Per Network Is Permitted!
-The Network Sounder (BBFF1) Must Be Used With at Least One NavNet Display!

Section 2 - The Three NavNet Cabling Options &
CAT5/RJ45 Installation Notes
•Option #1 – “Point-to-Point” With Two NavNet Components
Network Sounder (BBFF1)
When two NavNet Ethernet components are connected together, a single cable may
connect the Network Components. Refer to the list below for the appropriate length
cable. Utilizing any of the Furuno “6 Pin-to-6 Pin” Network Cables listed below is the
simplest way to network any two NavNet Network components.
Please note that the Network Sounder is supplied with a standard 5 Meter Network
Cable (000-144-4 ).

•Option #2 – Furuno Network Cables With Ethernet Hubs
Example of NavNet Installation Using Furuno 6-Pin Female-to-Female Cables and
Furuno Hub Adapter Cables 6-Pin Male to RJ45 Male)
This cabling option allows Furuno NavNet Cables to be utilized for any NavNet when an
Ethernet 10BASE-T Hub is required for a multi-component NavNet system.
Use the same cables as listed in Table 3.1 for connection to each NavNet Component.
This option might be beneficial for certain installations because it provides a waterproof
Furuno cable up to the Ethernet RJ45 Hub connection.
Furuno Cable Selection Steps:
A. Select a proper length cable from Table 3.1(Page 3) for EACH NavNet Display or
Network Sounder.
Each cable must be routed to a suitable location where the Ethernet Hub will be
mounted.
Note: The Ethernet Hub Connection will not be completely weatherproof unless the hub
is installed in a weatherproof box. Please pay careful attention to the mounting location
and installation of the hub.
B. Utilize one “Furuno Hub Adapter Cable” for each NavNet Component. A Hub
Adapter Cable is a 0.5 Meter Cable that will convert the 6 pin Furuno Plug to a Male RJ45
connector. This RJ45 connector will then plug directly into any 10BASE-T Hub.

•Option #3 – Utilizing CAT5 Cable for NavNet Installations
Example of NavNet Installation Using CAT5 Cables and
Furuno 6-Pin Female-to- RJ45 Male Display Adapter Cables
This type of installation requires the use of Furuno Display Adapter Cables. It is possible
to create a NavNet that only uses display adapter cables if the hub is mounted very close
to the NavNet Displays and Network Sounder. It is also possible to “Mix” cabling Options
# and #3 to create a NavNet.
When longer cable runs are required, it will be necessary to utilize CAT5 Network Cable
for NavNet Installations. Utilizing CAT5 Cabling provides flexible installations and allows
a vessel to be pre-wired during construction or in preparation for a future NavNet
installation.
-Waterproof integrity of dealer supplied CAT5 Cabling and/or connections is NOT
guaranteed by Furuno and must be performed by the installer.
-Exact CAT5 Network Installation Methods and Practices are MANDATORY! Please
see our “CAT5/RJ45 Installation Notes” below for help on this subject
All CAT5 Cables must be wired as “Straight” cables, because the connection will always
be made directly to the Ethernet Hub. “Straight” CAT5 wiring information will be provided
in the “CAT5 Cable Installation Notes”. Detailed information may also be found by using
our references in the Internet Resources section on page 8.

NavNet CAT5 Cable Installation Steps:
A. Pre-Wire the NavNet Installation with CAT5 or CAT5e Cable. Crimp Male R 45
Connectors to each end of the CAT5 Cable in a “Straight” Wiring Configuration.
Run CAT5 from each Display or Network Sounder in the NavNet to the location where
the hub will be mounted.
B. Attach a Female-to-Female R 45 Inline Coupler to the Display or Sounder CAT5
Cable End.
This RJ45 “Straight” Inline Coupler can be purchased at CompUSA or at other
vendors. The Belkin Part Number for this coupler is R6G089-F.
Do NOT use a “Cross-Over” Coupler.
R 45 Inline Coupler Female/Female Manufacturer – Belkin Part #R6G089-F
CompUSA SKU #612313
C. Attach One Furuno “Display Adapter Cable” to Each NavNet Display and Network
Sounder. Connect the Adapter Cables to the R 45 Couplers.
The Furuno Display Adapter Cable is a 0.5m cable with a female 6 pin connector on
one end and a male RJ45 connector on the opposite end.

NOTE: Creating a Watertight connection for the RJ45 coupler junctions is the
responsibility of the installer.
•CAT5 Cable and RJ45 Connector Information
While a complete explanation on installing CAT5 Network Cabling is beyond the scope
of this bulletin, some important information and excellent Internet resource material is
provided below to glean further knowledge about installing network cabling. These
guidelines must be followed when installing any Furuno NavNet Network Cabling.
CAT5 Cable Installation Notes:
A. Avoid Cable Stretching – The maximum pulling tension for CAT5 Cabling is 5lbs!
Exceeding this limit may cause permanent damage to the cable. CAT5 Cables utilize
exact twisted pairs for shielding protection. Distortion of the twists in the pairs
caused by excessive pulling could introduce noise problems. Use plenty of “Cable
Lube” when running cables in tight areas.
B. Avoid Tight Bend Radii and NEVER “KINK” CAT5 Cable During Installation – Over
bending CAT5 cable during installations will damage the cable. Avoid right angles
and do NOT tighten cable ties very tightly. Loose cable ties should be used to secure
CAT5 cabling. Tight cable ties will “Kink” CAT5 Cables. If a “Kink” is made in a CAT5
Cable, it should be replaced.

.
Page 7 11/16/01
C. Stranded or Solid Core CAT5 Cable is OK – For Cable lengths of up to 50 meters,
Stranded Core CAT5 Cable is OK and might be more suitable for high vibration
installations on smaller vessels. Solid Core CAT5 is also OK and should be used
on cable runs longer than 50 meters from a NavNet Display or Network Sounder to
an Ethernet Hub. Never exceed 80 Meters on a CAT5 cable run.
D. CAT5e Provides Better Interference Protection than Standard CAT5 – Enhanced
CAT5 (CAT5e) cabling is better to use than standard CAT5 Cable and is preferred for
NavNet installations. It costs only a few cents more per foot.
E. CAT5 Cabling Should NOT be Installed in Parallel with Power Cables – Try to run
CAT5 cabling independently from large power cable bundles, neon lights, or other
sources of EMI. Even a small separation from power cables provides enough
separation to reduce interference.
F. CAT5 Cabling Should Only Be Terminated With an R 45 Connector – NEVER use
any other kind of connector or normal terminal strip for CAT5 cables. The network
will simply not function if this is done. “110” Punch Down Blocks are acceptable.
Check our web resources on page 8 for more information.
R 45 Connector Installation Notes:
A. NEVER untwist CAT5 Cable for more than 0.5 Inches When Installing R 45
Connectors – The twist in the wire pairs is critical for CAT5 Networks.
B. Use Quality R 45 Crimping Tools and Thoroughly Inspect All R 45 Crimps –
Follow the Crimping Procedures listed in our www resources for more information.
C. Only “Straight Through” Cable Sections Are Required – When using Furuno
“Display Adapter Cables” in a multi-component NavNet System, only
“Straight Through” RJ45 terminations are utilized. Hubs use straight connections.
D. Follow only TIA/EIA-586 Wiring Standards – This means that wire colors and pin
assignments for the RJ45 connector must be consistent throughout the network.
Follow the CAT5 Wire Pair Color and Pin Assignments listed below. Even though
only two pairs are utilized, all four pairs MUST be crimped!!

SECTION 3 – Ethernet Hubs and Hub Power
A. General Ethernet 10BASE-T Hub Information
Furuno NavNet Network Components utilize standard IEEE 80 .3 Ethernet 10BASE-T
Ports. This simply means that any Ethernet 10BASE-T Hub can be utilized for NavNet
Products. Every Ethernet 10BASE-T Hub has multiple connection ports for individual
network connections. When NavNet Products use a Network Hub, we say that the
configuration of the network is a “Star”, where the Hub is the central location. Furuno
recommends using 4, 5, or 6 port 10BASE-T hubs because they consume low amounts
of power, are widely available throughout the world, and are physically small in size to
simplify mounting. The hubs that Furuno will specify all consume less than 0. 5
Amps@1 VDC. By definition, every 10BASE-T Hub has ports that utilize RJ45 modular
connectors.
Hubs are robust products that protect the integrity of the network. Both hardware and data
protection is provided by the hub. The Hub will automatically disable a network port that has
a shorted cable while the remainder of the network will still function. Hubs will also protect
the network from a Network Component that is placing bad data on the network or has
timing problems. Hubs also provide excellent feedback for technicians because they have
LCD Indicators for each individual port. Port activity and functionality can be determined by a
simple visual check of the hub itself! No other type of common high speed Network provides
this kind of “Network Watchdog” capability. This is the reason that about 95% of all new
Networks installed throughout the world are Ethernet based.
B. Powering The Ethernet Hub
In general, there are two methods to supply DC hub power in a NavNet System. These
methods are listed below:
•Hub Power Method #1 – Power the Hub directly from a NavNet Display
-Each NavNet Display has two 1 VDC Power Outputs that can EACH safely supply a
maximum continuous current output of 50mA or 0. 5 Amps.
-One 1 VDC Output is located on Port 1 of every NavNet Display. This output is usually
reserved for powering a GPS or DGPS Position Sensor, such as the BBGPS or GP36.
-The other 1 VDC Output can be used to supply power to the Hub and is found at DATA3 or
DATA4 of a NavNet Display.
STEP #1 – Cut Power Cable and Separate From AC Adapter
Cut the cable!

Page 10 11/16/01
STEP #2 – Use a terminal strip to connect the Hub Power Cable to the NavNet 12VDC
Output Cable. Choose a “Primary NavNet” Display to use for Hub Power. This display will
have to be turned on for the Hub to work!
Use the “DATA3” or “DATA4” 7-Pin (NMEA In, RS 3 I/O, 1 VDC Out, Buzzer) data port on the
rear panel of the NavNet Display to power the hub. The proper cable for these ports is the
000-144-418 Cable:
000-144-418 NMEA In/RS232C Out/Buz. Out/12VDC Out Cable
The “DATA3” and “DATA4” 7-Pin data port PIN ASSIGNMENTS are listed below and the wire
colors for this cable are also listed.
(WARNING! - The “DATA1” Port Pin Assignment is NOT THE SAME as the “DATA3” or
“DATA4” Port Pin Assignments. Be Careful!)
000-144-418 Cable Color Code
PIN #1 – TD WHITE RS232C “+” to PC or NMEA Output
PIN #2 – RD BLUE RS232C “-“ to PC
PIN #3 – NMEA In “+” YELLOW NMEA Input (SMART DEPTH SENSOR or OTHER)
PIN #4 – NMEA In “-“ GREEN NMEA Input (SMART DEPTH SENSOR or OTHER)
PIN #5 – “+”12VDC RED 12VDC OUTPUT (250mA Maximum Current Out)
PIN #6 – Buzzer Out BLACK Buzzer Output to Relay or Other
PIN #7 – GROUND SHIELD USE BARE SHIELD FOR +12VDC & RS232C GND
•Hub Power Method #2 – Power the Hub from Ship’s 12VDC through a Fuse or Breaker
The Ethernet 10BASE-T Hubs we suggest will have no problems when powered from
1 VDC Power through a breaker. If you have a larger 4VDC vessel, use a 4VDC-1 VDC
Voltage Converter or power the hub directly from the ship’s stable AC source using the
supplied 110VAC Adapter.
