The Leaf Pro is perhaps the easiest way to connect a computer to a CAN bus network by means of the standard USB interface and 9-pin D-SUB connector. Having made its name as the work-horse of USB to CAN interfaces, Kvaser’s Leaf interface family provide reliable, low cost tools for connecting any CAN network to a PC or mobile computer in applications as wide ranging as automotive, mining, marine, military, oil and gas exploration, industrial and heavy machinery.
Kvaser’s Pro versions boast a high transmit capability that meets the needs of CAN FD frames. The Kvaser 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 standard 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 customised 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, Kvaser AB, 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 standard feature of this sleek, ergonomically designed interface. With a 107cm long USB lead, and either a standard 9-pin DSUB or a 16-pin OBDII connector, the Kvaser Leaf Pro HS v2 and Kvaser Leaf Pro HS v2 OBDII suit a wide range of environments, from ECU development and test to in-the-field service situations.
