3 Introduction
This section will describe the functions and features of the Kvaser USBcan Professional.
3.1 Welcome to Kvaser USBcan Professional
Figure 1. Kvaser USBcan Professional.
Kvaser USBcan Professional is a powerful two channel real time CAN to USB interface.
The Kvaser USBcan Professional supports Kvaser's MagiSync™ technology to synchronize
time stamps across multiple units without extra wires providing flexibility for multi-channel
applications. With quick reaction times and high data throughput, the Kvaser USBcan
Professional is perfect for rapid ECU re-flashing, advanced bus analyzers, and efficient
development work.
This guide is applicable to the Kvaser USBcan Professional devices listed in Table 1.

and external triggers.
4.1 Hardware installation
The Kvaser USBcan Professional may be inserted in any free 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 Professional 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 Professional and the driver is installed on the host
computer. For additional information on how to upgrade the firmware, read section 6.5,
Updating the firmware.
The delivery package of Kvaser USBcan Professional contains:
Kvaser USBcan Professional.
Software and Driver CD, containing drivers for Windows; Kvaser CANKing, an easy to
use CAN bus monitor; Drivers for RP1210A, LabView and DIAdem; and Kvaser
CANlib Software Development Kit.
Kvaser USBcan Professional User's Guide (also on the CD.)
A USB cable.
For driver installation information, see the driver and hardware installation guide which can be
found at http://www.kvaser.com.
4.2 USB connector
The Kvaser USBcan Professional has a standard USB type ―B‖ receptacle connector.
Connect it to your PC using any high quality, USB 2.0 certified cable. The maximum USB
cable length is 5 meters (approx. 16.5 ft.). 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 Professional has two independent CAN channels that are seen
in Figure 2. The first CAN channel is marked on the housing with the symbol ‗1‘, where as the
second channel (number 2) is not marked. See Figure 3. The CAN connectors are also
labeled for easy identification.

5 How to use the Kvaser USBcan Professional
To use the Kvaser USBcan Professional 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 lamp will be illuminated and the yellow
lamps 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 Professional. Read out the firmware version. If
it‘s all zeroes, there are communication problems.
If the LEDs are flashing or glowing, compare the pattern with the specified LED
indicators in Table 2 and Table 3.
If the LEDs are not flashing or glowing at all, check the power supply.

6.5 Updating the firmware
Connect the Kvaser USBcan Professional to your PC with the USB cable. Double-click on the
file ―update.exe‖. A small application opens where you should see the device listed if correctly
connected to your PC (see Figure 7). Select the device to program and click the Next button.
Figure 7: Firmware update, select device.
Click on the Start Upgrade button to start programming (see Figure 8). The programming
takes approximately 20 seconds. The progress is printed on the screen, and typically looks
like this:

Kvaser USBcan Professional User's Guide 18(23)
Kvaser AB, Mölndal, Sweden —www.kvaser.com
Figure 8: Firmware update, start upgrade.
No error messages should appear. If you see error messages, try to disconnect
and reconnect the device, and then perform the operation again.
To verify that the firmware is updated,
Double-click on ―Kvaser Hardware‖ in the Control Panel. Select ―Kvaser USBcan
Professional‖ in the tree view to the left, and click on either channel. The firmware
revision information appears in the right half of the window.
6.6 Required driver version
You need at least driver (CANLIB) version 3.9 to use your Kvaser USBcan Professional.
6.7 CAN bus termination
Every CAN bus must be terminated with a 120 Ohm resistor at each end of the bus. The
Kvaser USBcan Professional does not contain any CAN bus terminators, because their
inclusion could cause severe disturbance in a system which is already correctly terminated.
For laboratory or testing use, the exact value of the termination resistors is not always critical.
Sometimes a single terminator is sufficient. For production, proper termination is essential. If
you see error frames on the bus, you should check the termination.

Kvaser USBcan Professional User's Guide 19(23)
Kvaser AB, Mölndal, Sweden —www.kvaser.com
To save yourself a lot of trouble, always terminate the CAN bus properly.

7 Frequently Asked Questions
Q: I want to read the messages sent on the CAN bus without interfering with the
system, how can I do that?
A: You should put the Kvaser USBcan Professional in Silent mode; that is, it doesn't send
anything, not even ACK bits, on the bus. Reception works as usual.
Q: I am trying to send CAN messages but I can’t se any messages on the bus.
A: Make sure the CAN channel isn‘t in Silent mode.
Q: Could I use several Kvaser USBcan Professional?
A: Yes, no problem. For MagiSyncTM to work make sure you connect them to the same root
hub.
Q: If I reboot my computer, will the Kvaser USBcan Professional and other products
have the same channel numbers as before?
A: Yes, they will try to reuse the old channel numbers.
Q: How can I identify which Kvaser USBcan Professional has a certain channel
number?
A: Use ―Kvaser Hardware‖ to flash the LEDs on the Kvaser USBcan Professional.
Q: How do I know which Kvaser USBcan Professionals are synchronized?
A: Use ―Kvaser Hardware‖ to flash the LEDs on an entire MagiSyncTM group.
Q: Do I have to use an external hub to keep the USBcan Professionals synchronized?
A: No, you don‘t. Just make sure they are on the same root hub.
