Real-time CAN to Ethernet interface for remote network access Kvaser Ethercan HS supports REST API and t programming

Real-time CAN to Ethernet interface for remote network access Kvaser Ethercan HS makes it easy to implement the "Internet of Things" (IoT) concept by enabling data from any CAN product or system to be sent over a corporate network or WAN, using the standard Kvaser CANlib API. Users of the Kvaser Ethercan HS can also choose to connect to the device using the built-in REST API for web-enabled devices, such as smartphones.

As a programmable interface, the Kvaser Ethercan HS interface is suited to advanced applications, such as ECU reflashing. For example, a t program could be created to process CAN messages locally in the device, removing the latency of WiFi and/or Ethernet.

I. Major features of Real-time CAN to Ethernet interface Kvaser Ethercan HS

• Networked CAN interface with Kvaser t programmability.
• Supports ISO 11898-1 with both 11-bit and 29-bit CAN identifiers.
• Compatible with applications written for other Kvaser CAN hardware using Kvaser CANlib.
• One high-speed CAN connection (compliant with ISO 11898-2), 40 kbit/s up to 1 Mbit/s.
• Fully compatible with J1939, CANopen, NMEA 2000 and DeviceNet.
• Supports Kvaser REST API.
• Ethernet connection with auto-MDIX using a standard shielded RJ45 socket.
• Built-in Power over Ethernet (PoE), allows the device to receive both data and power over a single Ethernet cable.
• Small and lightweight plastic housing.

II. The t programming language

• The Kvaser t programming language is event oriented and modelled after C. It can be used to customize the behavior of the Kvaser Ethercan HS and other Kvaser t capable devices.
• A t program is invoked via hooks, which are entry points that are executed at the occurrence of certain events. These events can be, for example, the arrival of specific CAN messages or a timer expiration.
• Like any Kvaser CAN interface, the Kvaser Ethercan HS can be used via CANlib on a host computer. The addition of t programs running directly on the Kvaser Ethercan HS makes it possible to react much quicker to CAN bus events (for example to speed up file transfer protocols or to simulate missing hardware).

III. Additional software and documentation cho Real-time CAN to Ethernet interface

• The Kvaser CANlib SDK includes everything you need in order to develop software applications interacting with Kvaser CAN and LIN hardware. The SDK contains full documentation and many sample programs, written in C, C++, C#, Delphi, Python and Visual Basic. Kvaser CAN and LIN hardware is built around the same common software API. Applications developed using one device type will run without modification on other device types.

IV. Kvaser Ethercan HS hardware

Hardware installation:

• The Kvaser Ethercan HS may be inserted into any free Ethernet socket. If the Ethernet socket does not support Power over Ethernet, power must be supplied on the CAN connector. For the Kvaser Ethercan HS to communicate with the host computer, a compatible version of the Kvaser driver and firmware must be installed. After the driver has been installed on the host computer, the firmware may then be downloaded and installed on the Kvaser Ethercan HS.

Network connector:

• The Kvaser Ethercan HS has a standard shielded RJ45 socket (STP) ethernet connector. Connect the Kvaser Ethercan HS to your network or directly to your host computer for first time configuration.

Ethercan Factory Reset Device:

• The Ethercan Factory Reset Device is used to reset the Kvaser Ethercan HS configuration.

CAN channels:

• The Kvaser Ethercan HS has one CAN Hi-Speed channel with a 9-pin D-SUB connector.

Power supply:

• The Kvaser Ethercan HS is powered either from the Ethernet connector using PoE or from the CAN connector. The Kvaser Ethercan HS is compliant with PoE IEEE 802.3af supporting both Mode A (endspan) and Mode B (midspan).

LED indicators:

The Kvaser Ethercan HS has four LEDs

The ERROR LED indicator can give more information about the cause of failure
