NAVLINK2 WIRELESS
NMEA2000 SERVER
Version 1.00

1. Introduction
Congratulations on the purchase of your Wireless NMEA 2000 Server.
This product replaces our original NavLink product and features a smart
web interface that can be displayed and configured using the web
browser on your mobile device.
It is recommended that your product is installed by a professional
installer, particularly when it comes to interfacing with other equipment.
Before installing and operating this unit you should consult
the user manual of the navigation equipment that you are
connecting this unit to.
2. Before you start
You will need the following items and tools to complete the installation:
•The Wireless NMEA 2000 Server (supplied)
•Spare/suitable connection to the NMEA2000 network
•M3 or M4 screws or other fixings appropriate to the mounting
location (not supplied).
To receive/display wireless data from the NavLink2 you will need:
•Suitable navigation software running on a PC, iPhone/iPad, Mac or
other wireless device.
•A fully working and powered NMEA 2000 network.


3. Installation
The NavLink2 is IP54 rated (water resistant) and should be installed
below deck in a dry location. When locating the unit you should consider:
•Routing of the NMEA 2000 cable to the network.
•Sufficient space around the unit for cable connections.
•Maintaining the compass safe distance of 0.5m.
•Best location for Wi-Fi reception i.e. not inside a metal enclosure
Installation Step 1 –Connecting to NMEA 2000 Network
•Connect the NavLink2 NMEA 2000 cable, to a spare connector on
the NMEA 2000 network.
•NavLink2 takes its power (LEN=2) from the NMEA 2000 network so
no additional connections are necessary.
•If you are creating a new NMEA2000 network, then you may wish
to consider Digital Yacht’s NMEA2000 Starter Kit, that provides all
of the cables, connectors and terminators required for a basic
NMEA2000 network.
•If you are connecting NavLink2 to a non-standard NMEA2000
network, then a suitable adaptor cable will need to be sourced
from the relevant manufacturer;
>SeaTalkNG (Raymarine P/No A06045)
>Simnet (Simrad P/No 24006199)
Installation Step 2 –Mounting
•Using suitable fixings, attach the NavLink2 unit to a flat surface.
•Unit may be installed in any orientation.
•The dimensions of the NavLink2 are provided on the next page.

Installation Step 3 –Powering NavLink2
•Apply power to the NMEA 2000 network and the NavLink2 the LEDs
should start to illuminate or flash, as per the following table…

Installation Step 4 –Wireless Interfacing
•By default, the NavLink2’s 802.11 b/g/n wireless adaptor, creates a
wireless Access Point (hotspot) on-board your boat. The Name
(SSID) of the Access Point will be “DY-WiFi-xxxx” where xxxx is the
unique four digit code of your device.
•To connect to the NavLink2 you will need scan for wireless
networks, select it and then enter the default WPA2 password,
which is “PASS-xxxx”, where xxxx is the same, unique four digit
code in the hotspot name.
•The NavLink2 can transmit wireless NMEA data using two different
network modes; either TCP (single device connection) which is the
default mode or UDP (multiple device connection).
•UDP mode can be selected in the smart web interface.
•Once your mobile device is wirelessly connected to the NavLink2,
open the navigation application that accepts NMEA data over a TCP
or UDP connection and setup the connection.
•Consult the help documentation for your App to see how wireless
data connections should be configured.
•The IP address and port that the NavLink2 transmits data on are;
IP Address - 192.168.1.1
Port - 2000
•Note that some UDP connections do not ask you to enter the IP
address just the port number.
4. Normal Operation
The NavLink2 consumes around 0.1 Amp and can be left on whenever
the boat is sailing. Every time NMEA 2000 data is received, the yellow
“DATA IN”LED will flash. In some systems with lots of NMEA data, it is
not unusual for the yellow LED to be constantly flickering.

Should you have a problem connecting wirelessly to the NavLink2, press
and hold the Reset button for 1-2 seconds and try connecting again. In
busy marinas with high levels of wireless activity, getting a reliable
connection to the NavLink2 may be difficult, but once underway (at sea)
a strong and reliable connection will be achieved.
If you have other wireless devices on board that create their own
wireless networks, use the Wi-Fi Channel selection option in the Smart
Web Interface to use a different Wi-Fi Channel to the other devices.
Alternatively, if the boat already has a Wireless Router onboard, you can
make the NavLink2 connect to that network, rather than create its own.
Select “Station” mode in the Smart Web Interface.
Using the NavLink2’s Web Interface
Any device, wirelessly connected to the NavLink2, can access its web
interface by typing http://192.168.1.1 in to its browser’s address bar.

From the Web Interface you can configure all of the NavLink2s features.
1. Networking Mode
•In Access Point mode, the NavLink2 creates its own wireless network with the
name, password, IP address, Port and Wi-Fi channel you select. If you leave the
Password box blank, it will create an “Open” unprotected network.
•In Station mode, the NavLink2 will try to join another wireless network
whenever it powers up. The network can be selected from a drop down list and
if it is password protected, enter the correct password in the password box.
2. Communication Settings
•The Baud rate on the NavLink2 is pre-set to 230400 and cannot be changed
•Set the communication protocol to UDP or TCP
3. Firmware Update
•The firmware of the NavLink2 can be updated using web interface, simply click
the “Choose file” button to browse your device for the firmware update file and
then once selected, click the “Upload Firmware” button
After changing any of the settings on the Web Interface, click the “Update Settings”
button to save and apply your changes. If the changes affect the networking then
the NavLink2 will reboot and you will need to reconnect wirelessly to it.
If you make a mistake with a setting or forget a password, reset the NavLink2 to
factory defaults by pressing and holding the Reset button for 10 secs or more.
For diagnostic
purposes, you can
view the received
NMEA0183 data by
clicking the “View
Data” button which
opens a new
browser tab
displaying the raw
NMEA0183 data
received.
