NAVDoctor NMEA Network Diagnostic Tool
NAVDoctor is the perfect NMEA 2000 diagnostic tool for dealers, installers, and boat builders. It turns any mobile device into an NMEA 2000 network analyzer, creating simple and clear web pages that show the health and status of your NMEA 2000 network.
NAVDoctor is a portable NMEA 2000 network diagnostic tool/tester. It allows you to quickly check and diagnose the NMEA 2000 network. It combines the functionality of existing NMEA 2000 display programs and test equipment into a single, cost-effective, simple plug ‘n play box.
It’s self-powered from the network and creates a local wifi point for a mobile phone, tablet, or PC to connect. Once connected, you simply access functions through a web browser so there’s no complicated software to install.
NMEA 2000 networks are based on a robust Canbus architecture, but one bad device, cable, or termination can have a detrimental effect on performance. Fault finding can be time-consuming and tricky, so having a NAVDoctor in your toolkit will save you time, money, and frustration.
NAVDoctor is an essential tool for every marine electronics technician or installer and also offers the capability of printing a network health check certificate to validate an installation and improve customer service.
Operation
You can configure the NavDoctor through its simple web interface, just open your web browser, enter the NavDoctor’s IP address and you can access the NavDoctor web interface. So no complicated programming software or app is required.
Through the web interface, you can analyze all the equipment connected to the NMEA 2000 network and get additional information about the equipment. You can also display all the NMEA 2000 data (PGN) being received.
The health section gives you an overview of the NMEA 2000 network (voltage, bus capacity, etc.). Finally, the test report section analyses all the NMEA 2000 network, equipment, and data and can generate a PDF.
