“Using the Kvaser 2x CAN/LIN device, find and example program to send LIN
commands through python so i can test the interface. Do you have any example for it or at least a program that i might use to test the commands cause I only seen python CAN commands in your site”

If you have CANlib SDK installed on your PC, you can find a tutorial for using LIN at the linlib.html in the following CANlib SDK install directory:
C:\Program Files (x86)\Kvaser\Canlib\Samples\Python\pycanlib.zip\pycanlib\docs\tutorials\

Don’t forget that when using a channel as a LIN interface, you must provide power V+ on pin 9 of the channel connector and GND on pin 3.
