The Maretron N2K Diagnostics Meter is obsolete and has been replaced by the PEAK-MiniDiag NMEA 2000!

Note: The PEAK-MiniDiag NMEA 2000 is  the same meter the NEMA organization is using for all their advanced trainings.  Click link here to see details:

Product Description:

The N2KMeter is a diagnostic tool for NMEA 2000® networks that allows users to validate NMEA 2000® network compatibility and operations during installation of a device or complete system, and diagnose possible network flaws or failures that occur on an operational network. N2KMeter provides the detailed technical information an NMEA 2000® troubleshooting expert needs, yet it simplifies and summarizes, allowing an NMEA 2000® novice to effectively identify and diagnose network problems. Battery-powered operation allows a novice user to save readings for experts to analyze later, off the boat.

The N2KMeter enables trained and untrained personnel to diagnose and troubleshoot network installations quickly and easily. Passive on the network, it analyzes both network-wide and device-specific traffic. Detects bus idle and 100% of individual CAN frames in real time. N2KMeter uses a patented integrated intelligence technique to summarize multiple NMEA 2000® network operational variables into a single health index.

To a service technician, it’s a “guru-in-a-box”, providing a detailed reading of network performance. It displays NMEA 2000® network health by displaying a happy face icon, indicating a healthy network; a sad face, indicating a serious problem; or a neutral face, indicating nominal performance (a good indication to repair things before they actually fail). N2KMeter then walks the user through each fault condition and its source, or it can record key operating parameters for offline review.
