4 Kvaser USBcan R hardware
In this section you can read more about the CAN bus channels, USB connector, and LED
indicators.
4.1 Hardware installation
The Kvaser USBcan R may be inserted in any unused USB socket on the host computer.
You do not need to switch the power off before inserting or removing the device. For the
Kvaser USBcan R to communicate with the host computer, the correct version of the Kvaser
driver and firmware must be installed. The firmware is downloaded and installed directly on
the Kvaser USBcan R and the driver is installed on the host computer.
The delivery package of Kvaser USBcan R contains:
Kvaser USBcan R
4.2 USB connector
The Kvaser USBcan R has a standard USB type ―A‖ plug. If you need a longer cable, you
can use USB hubs or USB extension cables with a built-in hub. By chaining up to 5 hubs, you
can achieve a cable length of up to 25 meters (approx. 83 ft.).
4.3 CAN channels
The standard Kvaser USBcan R has two independent CAN channels with a common ground.
The connectors for these channels are shown in Figure 2.

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.
