SWEDISH CAN HARDWARE PROVIDER Kvaser has announced two additions to its Kvaser Leaf CAN to USB interface series, the Leaf Pro HS v2 and Leaf Pro HS v2 OBDII. This Versions of the Leaf family brings programmability to user’s fingertips, as well as CAN FD functionality.

According to the company, the Leaf Pro is perhaps the easiest way to connect a computer to a CAN network by means of the standard USB interface and 9-pin D-SUB connector. The interfaces provide tools for connecting any CAN network to a PC or mobile computer in application areas such as automotive, mining, marine, military, oil and gas exploration, industrial, and heavy machinery.

The Pro versions boast a high transmit capability that meets the needs of CAN FD frames. The Leaf Pro HS v2 transmits the 64 data bytes of a CAN FD frame at bit rates up to 8 Mbit/s, in addition to Classical CAN frames of 8 bytes. With a maximum message rate of 20000 messages per second, each time-stamped with a one microsecond accuracy, this is a highly advanced, portable real-time CAN to USB interface that can be customized using Kvaser’s t programming language. For example, users can run a t program to speed up file transfer protocols or to emulate ECUs and other devices by generating traffic and handling protocols.

Commenting on the announcement, Lars-Berno Fredriksson, president of Kvaser, said: “Our best-selling interface just got better. CAN FD-capability and programmability make the Kvaser Leaf Pro HS v2 and Kvaser Leaf Pro HS v2 OBDII our most capable Leafs yet!” Galvanic isolation is a regular feature of the interfaces. With a 107 cm long USB lead, and either a standard 9-pin DSUB or a 16-pin OBDII connector, both products suit a range of environments, from ECU development and test to in-the-field service situations.
