Digital Yacht NAVDoctor NMEA 2000 Diagnostic Tool

The Digital Yacht NAVDoctor NMEA 2000 Diagnostic Tool gives installers and boat owners a portable way to inspect the health of an onboard NMEA 2000 network. It is self-powered from the network and creates a local wireless connection for a phone, tablet, or computer. Once connected, the built-in web interface displays devices, transmitted PGNs, and key network information without requiring a separate application. That makes it useful for commissioning a new backbone, documenting an installation, or tracking intermittent network problems.

The health page provides a quick view of network conditions such as bus voltage and capacity, while the device and data pages let the technician drill into what each connected product is sending. NAVDoctor can log network traffic to a text file when a longer capture is needed for deeper analysis. Because all of those functions run through a browser, the same tool can move easily between workshop laptops and mobile devices on the boat. It can also generate a network health report that can be printed or saved as a PDF for customer records or service documentation.

• NMEA 2000 wireless diagnostic and test tool
• Self-powered from the NMEA 2000 bus
• Logs network data for detailed troubleshooting
• Lists connected devices and transmitted PGNs
• Generates printable or PDF network health reports

The tool is supplied with the network connection hardware needed to put it on an NMEA 2000 backbone and begin testing. For the best diagnostic result, connect it to a correctly terminated network and compare the reported voltage, device list, and PGN traffic with the system design. It is especially useful after adding or replacing electronics because it provides a repeatable way to verify network health before the boat leaves the dock.
