Since the original work the use of CANbus has grown enormously, and is no longer confined to the automotive industry.

This has led to many chip manufacturers supporting CANbus with many advanced features in silicon (like message filtering) - good news for the user!

Where would you find CANbus?
In cars (J1939) , in boats (NMEA 2000), in factories (CANopen, DeviceNet, and SERVOnet) - and even in theatres!

So why use CANbus?
You can throw away the wiring loom - and replace it with two wires! Smart gauges and sensors can be directly connected to the CANbus, sensor and control modules can read/send data, display systems can read/log data. And because it is a network it doesn't matter where a component is physically located. CANbus also has the bandwidth to cope with real time control as well as data collection.

Start dreaming!
Think of a vehicle where modular sensors and controls connect to a network backbone. Information display panels then show the driver/operator what he needs to know. Logging of information feeds the service system. Secondary panels display information where it is needed (e.g. next to the valves on a tanker).

We have been using CANbus in marine applications for quite some time, and have built up the expertise to implement these ideas, today.

NETWORK STANDARD

The National Marine Electronics Association has introduced the long awaited NMEA 2000 interface standard.

The standard contains the requirements of a serial data communications network to inter-connect marine electronic equipment on vessels. It is multi-master and self configuring, and there is no central network controller. Equipment designed to this standard will have the ability to share data, including commands and status with other compatible equipment over a single channel.

NMEA 2000 represents the cumulative efforts of the BETA Testing Group, a committee of industry and government professionals who have contributed time and expertise to the development and completion of this product.

A complete discussion of NMEA 2000 is included as well as the names and affiliations of the BETA Test Group.

NMEA 0183 INTERFACE STANDARD

(document)

The Interface Standard is a COPYRIGHTED document.

The NMEA 0183 Standard for Interfacing Marine Electronics Devices is a voluntary industry standard, first released in March of 1983. The NMEA 0183 Standard defines electrical signal requirements, data transmission protocol, timing and specific sentence formats for up to 38.4K baud serial data bus.

The Standard has been updated from time to time and the latest release, July 2000, Version 3.01, is available from the NMEA national office by sending a check made payable to NMEA drawn on a U.S. bank in U.S. dollars. Please include a complete mailing address for the document to be shipped via the postal service priority or airmail delivery. You may also use VISA,  MASTERCARD or AMERICAN EXPRESS charge by faxing the card information (name on card, account number and expiration date) along with shipping instructions to 410-975-9450.
