NMEA2000 Option For CANalyzer

Download Datasheet

NMEA 2000 is a communication protocol of the National Marine Electronics Association (NMEA) based on J1939 for data exchange between control units in a marine application.

Features and Advantages

In addition to CANalyzer's high-performance functionality the .NMEA2000 Option gives the user a tool that can be used for initial development to production of a NMEA2000 project. The NMEA2000-specific extension allows the user to concentrate on the actual tasks of data analysis without requiring detailed knowledge of the NMEA2000 protocol. This significantly increases the efficiency of data analysis. Misinterpretations of CAN frames are avoided.

Functions

The .NMEA2000 Option for CANalyzer expands the standard functionality of the CANalyzer with:

Support for the BAM, CMDT, and Fast Packet transport protocols
Protocol-specific representation in the Trace Window
GNSS/GPS display and simulation
Graphic display of the network nodes (scanner)
Expanded database
Diagnostic Trouble Code Monitor (DTC Monitor)
Diagnostic Memory Dialog (DiagMem)

Application Areas

The NMEA2000 Option for CANalyzer can be used everywhere NMEA2000 networks are developed, diagnosed, and tested. Networks can also be stimulated to a limited extent.

Hardware Interfaces

All interface cards supported by CANalyzer can be used. For compatibility, however, the use of ISO11898 (ISO High speed) compatible bus drivers (for example CANcab 251 or CANcab 251opto) is recommended.

Transport Protocols

There is a display of signals that are transmitted using parameter groups. When the "Fast Packet Transport Protocol" is used, the NMEA2000 Option for CANalyzer can reassemble the individual CAN messages transmitted. Since the interpretation of the NMEA2000 protocol can be restricted to the CAN channels selected by the user, gateway solutions with various protocols can be monitored.

Protocol-specific Display

Signals selected by the user are displayed in the Data Window. A wide range of display options are available to the user for this purpose, including bar diagrams, hexadecimal, decimal, and binary display. The NMEA2000-specific coding of the signal values "Error" and "Not Available" is realized with the help of a status display. Signals can be displayed and evaluated as a function with respect to time in the Graphics Window.

The NMEA2000 Option for CANalyzer allows the user to monitor communication symbolically. Communication is displayed in the Trace Window that displays the parameter groups transmitted. All relevant information is output in individual columns such as parameter group number, priority, and source and target address.

GNSS/GPS Display and Simulation

Display of the current position data (GNSS/GPS) occurs in a special window. Here the saved path is mapped and displayed graphically. In addition to the position, the current speed and height information are output. With the GNSS simulator, a path can be defined and followed virtually. This enables the easy simulation of corresponding devices. Playback of previously-recorded paths is also possible.

Scanner

The scanner monitors communication and makes available a clear display of all network nodes. Information about the functionality and manufacturer is output for every node displayed. If necessary, a central and clear reconfiguration of the node addresses can occur.

Database

NMEA2000 parameter groups and signals are described in a database. This database is already filled with all standard objects. This makes it possible to define application-specific parameter groups, for example. Parameter groups and signals defined thus can be selected symbolically in the entire program.
