Leaf Light HS v2 - CAN Bus USB Interface for Vehicle Electronics

VCI for simple communication tasks with CAN FD und Classic CAN

CAN communication interfaces are an inexpensive alternative to diagnostic interfaces. The Leaf Light HS from KVASER is a powerful hardware interface to be used for simple communication tasks. With the new product variant Leaf Pro HS it is possible to communicate with CAN FD as well as with Classic CAN.

 

Areas of Application

  • Simple communication tasks
  • Communication with Classic CAN or CAN FD
  • Applications in the After-Sales Service environment
 

Advantages

  • Active interface with its own microcontroller
  • Easy to use
  • Lightweight and smart housing
  • Inexpensive solution

CAN API

The programming interface from KVASER-Interfaces provides powerful communication mechanisms for CAN applications. Local buffering and preprocessing on the VCI result in high performance and a reduction of timecritical tasks for the PC.

D-PDU API

The standardized programming interface provides applications with powerful multi-channel communication mechanisms with vehicle protocols, such as Diagnostics on CAN (ISO 15765) and UDS (ISO 14229). It also allows integration into diagnostic systems in accordance with ISO 22900 (MVCI). D-PDU API is available as an option.

Scalability

If your application requires more than one CAN bus at any time, the number of communication channels available at the PC can quickly be extended. This is simple to organize by combining the existing CAN interface with further CAN or EDIC® interfaces from Softing

Flexibility

Combining Leaf Light HS v2 with appropriate API software enables compact solutions for all kinds of communication applications. The KVASER programming interface thus supports reliable CAN communication on Layer2 in a simple way. The optional D-PDU API software makes communication channels with higher diagnostic protocols available to applications via the standardized API and thus relieves the application of standard tasks.
