What does a NMEA 2000 do?
CAN was originally used in the automotive industry, but now it is used in many industrial fields and produced by many manufacturers.
NMEA2000 protocol is an application protocol based on CAN bus, with a baud rate of 250 kbps. Multiple devices can be connected on a single bus. It has many advantages such as high capacity, low cost of laying lines, and can achieve data transmission between ship equipment. The speed is 26 times that of NMEA0183, and it is increasingly widely used in marine equipment.
Ships are generally equipped with a set of electronic equipment, including desktop and laptop computers, GPS, and magnetic disks with navigational instrument data. The NMEA 2000 protocol, which implements the communication function between these devices, is a plug and play communication standard. Use a simple cable network instead of the current interconnection of multiple cables. Even devices manufactured by different manufacturers can always communicate with each other on the same network without interfering with each other.
In NMEA 2000, in addition to some common PGNs such as network management and device management, different devices support different PGNs. Although the entire protocol is relatively complex, the function is relatively simple for specific devices.
NMEA 2000 can meet the requirements of marine equipment, generator sets, marine engines, navigation, rudder systems, fire alarm, and control. Both data and command transmissions share the same cable. NMEA2000 is self configuring and does not require settings or controllers. Devices can be added or removed without shutting down the network.
These applications appear on ocean going vessels, coastal vessels, fishing vessels, and cruise ships, but they all require standard data for communication to varying degrees.
Premier Cable designs and manufactures cable assembly and connectors that support open standard cables, cable assemblies, connectors, terminals, and power supplies for NMEA 2000 systems, such as: NMEA 2000 Drop Cable, NMEA T Connector, NMEA Wireable Connector, NEMA T-Cross, NMEA BackBone Cable, and NMEA 2000 Terminator Resistor. Leave us a message for more customized.
While there are many factors to consider when designing an overall system, terminal blocks are an optimal solution for complex electrical system connections. With a variety of color options and configurations, Premier Cable’ terminal blocks offer a range of options to meet your design challenges.
CAN-bus has been widely used in various automation control systems. For example, CAN-bus has incomparable advantages in various fields such as automotive electronics, automatic control, smart buildings, power systems, and security monitoring.
M12 encoding types are A encoding, B encoding, D encoding and X encoding. A-code, B-code and X-code are some of the earliest developed and longest-available M12 connectors. The latest M12 coding types currently under development are K coding for AC and L coding for PROFINET DC.
The three different sizes of NMEA 2000 certified DeviceNet standard cabling are "micro," "mid," and "mini."
The Premier Cable Starter Kits provide everything you need to get to create a basic NMEA 2000 network from scratch.
DeviceNet_network is a fieldbus network protocol based on Controller Area Network (CAN). In the DeviceNet network, the terminal resistor plays the role of compensation and protection for signal transmission. The function of the terminal resistor is to eliminate signal reflection and interference and ensure the signal transmission quality.
