NMEA 2000 Display App For iKonvert USB

Installation and Instruction Manual

Introduction

With more and more modern boats having an NMEA2000 network at the heart of their navigation system, it is really important that you have the tools to investigate the devices and data on the network should things not work as planned. There are some NMEA2000 tools available but they only run on Windows and do not support all of the latest PGNs plus they can be difficult to install.

The world's First Multi-Platform Browser-Based NMEA2000 Display App

Getting Started

Digital Yacht's NMEA2000 Display App takes a new approach and is the World's first multi-platform, browser based NMEA2000 Display App that will run on Windows, LINUX, Mac OSX and Raspbian. There is no installation and if you can save a file and find it again, then that is as complex as it gets with just a single HTML5 file to worry about (less than 0.5MB in size). You need to use an app with a browser that supports the Web Serial API, which currently includes Chrome, Chromium, MS Edge and Opera. We also plan to support Firefox going forward (with its WebSerial Extension) but this was not possible for the first release of the app.

Designed to work with our iKonvert USB Gateway, simply download the free App from our dedicated GitHub site: https://github.com/digitalyacht/NMEA2000-Display-App

Unzip the file and after plugging your iKonvert USB in to your computer, double click the HTML file. Your default browser will open the web App and display the welcome page.

A screenshot shows the welcome screen of the NMEA 2000 Display Program, prompting the user to connect to their device. It instructs the user to click the 'Connect' button and select the appropriate USB serial port, mentioning an 'Auto Detect and Connect' feature.

Click the CONNECT button and the app will search for the iKonvert USB and display all of the USB serial ports that it found.

A dialog box from the NMEA 2000 Display Program shows a prompt to select a serial port for connection, listing available USB serial ports.

Using the NMEA 2000 Display App

Viewing PGN Data

Select the serial port that has been allocated to your iKonvert USB and click the CONNECT button. The app will now start checking what baud rate the iKonvert USB is set to (takes less than 10 seconds) and as soon as it detects the baud rate, set the iKonvert USB to its RAW NMEA2000 Mode (230400 baud).

Now the app will start receiving PGNs and displaying them in a table.

A screenshot shows the NMEA 2000 Display Program interface displaying a table of received NMEA 2000 data, with various PGNs and their associated details.
