1 General

1.1 Introduction

Congratulations on your purchase of the Maretron N2KMeter. The N2KMeter is a diagnostic tool
®
for NMEA 2000 networks that allows users to validate NMEA 2000
operations during installation of a device or complete system, and diagnose possible network
flaws or failures that occur on an operational network.
Please read carefully and follow these instructions for usage of the Maretron N2KMeter in order
to ensure optimal performance and accurate measurements.

1.2 Features

The 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 summarizes 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). The N2KMeter then walks the user
through each fault condition and its source, or it can record key operating parameters for offline
review.
Faults that can be detected by the N2KMeter include
 Opens and Shorts
 Incorrect Topology
 Bad Nodes
 Bad Termination
 Improper Shield Connection
 Intermittent Problems
 Excessive Scan Rate
 Common Mode Voltage
