The Leaf Light v2 OBDII provides a simple way of connecting a PC with the on-board computer in any vehicle by means of its USB 2.0 connector and a 16-pin OBDII compliant CAN connector. Meanwhile, the Kvaser Leaf Light HS v2 J1939-13's USB 2.0 connector and 9-pin J1939-13 compliant CAN connector suits commercial vehicle diagnostic applications.
All Kvaser Leaf Light v2 interfaces support high speed USB and can send up to 8000 messages per second, each time-stamped with 100 microsecond accuracy. Galvanic isolation, previously a more expensive option on the company's original Leaf Light, now comes as standard, enhancing protection from power surges or electrical shocks.
Used with the vendor's CANlib library, which is free to download from Kvaser’s website ( www.kvaser.com), the Leaf Light v2 series provides application programmers with quick and easy access to the CAN network. The software enables hardware initialization, bus on/off, setting of bus parameters and buffers, as well as read/write commands.
