    Kvaser Leaf User Guide 5 (65) Introduction The Kvaser Leaf family currently consists of three basic products: Kvaser Leaf Light, Kvaser Leaf SemiPro and Kvaser Leaf Professional. Kvaser Leaf SemiPro and Kvaser Leaf Professional use the patented Kvaser MagiSync that you can read more about in Section 1.1 Kvaser MagiSync...

    2.0 is backwards compatible with 1.X. Kvaser Leafs will work on your computer with all standards, but if you do not have USB 2.0, the Kvaser Leafs will use full-speed at max. 12 Mbit/s. GMGA MEASURING - Hanoi, Vietnam — https://gmga.vn/...

  • Page 10: Power

    Power All Kvaser Leaf devices are powered through the USB connector. The host must supply 5 V DC, as per the USB specification. Some device types also need a reference voltage on the CAN or LIN connector. This is described in detail in Section 2.6.2, Reference Power (pin 9), on Page 13.
  • Page 11: Leds

    USB connector The Kvaser Leaf device may be connected to any free USB socket on the host computer. Power does not have to be turned off before inserting or removing the device. It is good practice, though, to exit all applications using the CAN hardware before removing a Kvaser Leaf device.
  • Page 12: D-Sub Connector

    In high speed mode an external load resistor of 180 is required. Pin 4 has an 180 resistance connected through a switch to ground (pin 3). When the Kvaser Leaf is configured to "high speed" mode by software, this switch closes. To acquire the needed pull-down resistor, the user needs only connect pin 4 to pin 7;...

  • Page 14 This value is chosen as to load the system as little as possible. You will probably need to add extra pull-up and pull-down resistors to the CAN bus unless the system you connect the Kvaser Leaf to already has a proper resistor configuration. GMGA MEASURING - Hanoi, Vietnam — https://gmga.vn/...
  • Page 15: Obdii Connector

    When running the SWC bus in its high-speed mode, a Ω load resistance of 180 from CAN_H to ground is required. The Kvaser Leaf hardware Ω supports high-speed as a master and has an internal 180 which is automatically switched in when required, as seen in Figure 8 on Page 13.
