The USB-CAN Plus ISO is an adapter from USB 2.0 to CAN bus, with galvanically isolation. It connects a PC via the USB interface to the CAN bus, while protecting the PC from high voltage problems on CAN bus signals. The CAN port is isolated for 2.5kV. The CAN port and USB are ESD protected, compliant to IEC 61000-4-2 (8kV contact/16kV air discharges).
Since current computers all have several USB ports, the installation is simple. Even the previous standard of USB 1.1 with 12 Mbit/s max. speed is sufficient to connect the USB-CAN+ ISO to a computer.
CAN bus is widely used in industrial applications as well as in automotive monitoring and control. The USB-CAN+ ISO can be used to monitor the data traffic in such installations, as well as sending control information. The performance of USB-CAN+ ISO is among the best available in the market of CAN-on-USB products.
Since hardware-based automatic flow control is implemented at the interface between the CAN controller and the PC, the data reliability is very high.
• The ASCII conversion protocol is useful in developing and testing any configuration. Users just open the serial port via a Terminal Program, and have a simple way to talk to the CAN controller. The same way they can also transmit and receive CAN frames.
• Applications programmed by users load the library (DLL), which transparently handles the ASCII conversion. Programmers handle only the CAN frames and status, they do not have to care about the ASCII conversion in their applications. This API is supported in C/C++, C#, VB.NET, Delphi and LabVIEW.
• In Linux SocketCAN can be used as alternative to vs_can_api library. VScom CAN devices support standard Serial Line CAN (slcan) driver (see this FAQ).
• USB-CAN+ ISO also supports CANFestival, an Open Source CANopen Framework. CANopen is a CAN-based higher layer protocol that is used in various application fields, such as medical equipment, offroad vehicles, maritime electronics, railway applications or building automation. CANopen unburdens the developer from dealing with CAN-specific details such as bit-timing and implementation-specific functions. It provides standardized communication objects for real-time data, configuration data as well as network management data.
• CANHacker, a tool for analyzing and transmitting frames on the CAN BUS, is included in the product package.
• A set of Mapper DLLs simulates CAN hardware from other manufacturers. Users configure their system for those products or the USB-CAN+ ISO adapter as a replacement. So existing software will use the USB-CAN+ ISO without replacing the application or modifying it.
The USB-CAN Plus ISO succeeds the VScom USB-CAN ISO adapter.
