The Leaf SemiPro from Kvaser is a single-channel USB-CAN interface offering galvanic isolation from the CANbus. The time-stamping of CAN messages is synchronized through Kvaser's patented MagiSync™. Multiple devices of the same or different CAN transceiver type can be operated on the same computer for maximized flexibility and scalability. Besides this High-Speed CAN version the Leaf SemiPro is also available as Low-Speed (part# KV-00260-9) and Single-Wire (part# KV-00263-0) CAN product version.
- Automatic and accurate clock synchronization between several Kvaser Leaf SemiPro interfaces through Kvaser MagiSync™. The technical solution is unique and patented by Kvaser.
