Version 1.01

1. Introduction
Congratulations on the purchase of your NAVDoctor Wireless NMEA 2000
Diagnostic and Test tool. In addition to this quick start guide, we recommend
watching this video https://www.youtube.com/watch?v=HfuUEdKeBX4
This product is designed for use by Technical Dealers and Installers with
knowledge/experience of NMEA 2000, Digital Yacht cannot provide
technical support or training on NMEA 2000 networking.
2. Before you start
To use your NAVDoctor you will need:
•A wireless device with web browser i.e. Smart Phone, Tablet or Laptop
•A spare “T-Piece” connection on a working/powered NMEA 2000 network.
3. Operation
The NAVDoctor is IP54 rated (water resistant) and care should be taken when
operating it, to ensure it is not submerged in water.
3.1 –Connecting to NMEA 2000 Network
•Connect the NAVDoctor cable, to a spare connector on the NMEA2000 network.
•NAVDoctor takes its power (LEN=2) from the NMEA2000 network so no
additional connections are necessary.
•If you are connecting NAVDoctor 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)
3.2 –Mounting
NAVDoctor is primarily designed to be portable, for use on different installations,
as part of a marine technician’s tool kit. However, on a larger vessel, NAVDoctor
could be permanently installed to a flat bulkhead using suitable fixings. NAVDoctor
can be installed in any orientation.

3.3 –Powering NAVDoctor

3.5 –Accessing the Web Interface
•The NAVDoctor has a built-in web interface, consisting of a series of pages
that provide key information on the status of the NMEA 2000 network.

a browser at http://192.168.1.1 or http://navdoctor.local which should
bring up the NAVDoctor home page as shown in Figure 1.

4. Settings
By default NAVDoctor creates its own wireless network but if you are going to be
using it in a workshop environment, where there is already a wireless network,
you can make NAVDoctor join this network rather than create its own.
From the Home page, click on the Settings icon/button and in the Network
Settings section at the top of the page select Station mode, see Figure 7.
Click the Scan button to scan for available wireless networks, select the network
you want to join from the drop-down list, enter the wireless password and click
the Update Settings button.
Figure 6

NAVDoctor will now display a window saying that the Wi-Fi settings have been
changed and the unit will now reboot. On rebooting it will try to join the selected
wireless network and if successful the Status LED will stop flashing a few seconds
after booting up and stay permanently ON.
If you have any problems connecting to another network, press and hold the Reset
button on the bottom edge of the unit for >10 seconds and NAVDoctor will reset to
factory defaults.
Also, on the Settings page are the details of the Gateway and Wireless firmware
versions and the free memory value. Updates to the wireless firmware can be done
via the web interface –contact support@digitalyacht.co.uk for more information.
