USB-CAN Interface 1 channel - computer connection to CAN bus network
The Kvaser Leaf Light HS v2 represents one of the easiest and lowest-cost methods of connecting a computer to a CAN bus network. With its USB 2.0 compliant connector and 9-pin D-SUB connector, the Leaf Light HS v2's sleek, ergonomically designed housing is both robust enough for everyday use and small and flexible enough to be used in space-constrained applications. The Kvaser U100 is a robust, single-channel CAN/CAN FD to USB interface with reinforced galvanic isolation that squarely addresses the needs of the evolving automotive development market. Fully compatible with J1939, CANopen, NMEA 2000® and DeviceNet, this is the first in a new range of interfaces that is also suited to rugged applications in marine, industrial, heavy duty vehicle and heavy industries.
Key Benefits of CAN
Distributed Control Systems
The CAN protocol is a good basis when designing Distributed Control Systems. The CAN arbitration method ensures that each CAN node just has to deal with messages that are relevant for that node. A Distributed Control System can be described as a system where the processor capacity is distributed among all nodes in a system. The opposite can be described as a system with a central processor and local I/O-units.
Hardware Implementation
The CAN protocol is implemented in silicon. This makes it possible to combine the error handling and fault confinement facilities of CAN with a high transmission speed. The method used for distributing messages to the right receivers contributes to gaining a good use of the available band width.
Simple Transmission Medium
A common transmission medium is a twisted pair of wires. A CAN system can also work with just one wire. In some applications different kinds of links, optical links or radio links, are better suited. Though there is a transmission hardware standard (twisted pair), it is not uncommon to use different transmission solutions depending on system requirements.
Excellent Error Handling
The error handling of CAN is one of the really strong advantages of the protocol. The error detection mechanisms are extensive, and the fault confinement algorithms are well developed. The error handling and retransmission of the messages is done automatically by the CAN hardware.
Impressive Fault Confinement
A faulty node within a system can ruin the transmission of a whole system, e.g. by occupying all the available band width. The CAN protocol has a built-in feature that prevents a faulty node from blocking the system. A faulty node is eventually excluded from further sending on the CAN bus.
Mature Standard
The CAN protocol has been around for almost 30 years (since 1986). There are now a lot of CAN products and tools available on the open market.
