5 How to use the Kvaser USBcan R
To use the Kvaser USBcan R as a CAN interface; connect the unit to a free USB socket on
your PC or USB hub.
When used as a CAN interface, the green LED will be illuminated, and the yellow
LEDs will emit short flashes when CAN messages are transmitted and received.
5.1 Troubleshooting
Use ―Kvaser Hardware‖ in the Control Panel to verify that the computer really
can talk to the Kvaser USBcan R. Read out the firmware version. If the
firmware version is all zeroes, there are communication problems.
If the LEDs are flashing or glowing, compare the pattern with the specified LED
indicators in Table 1 and Table 2.
If the LEDs are not flashing or glowing at all, check the power supplied through
the USB connection.
