3 Kvaser USBcan Light 4xHS hardware
In this section you can read more about the CAN channels, power supply and LED
indicators.
3.1 Hardware installation
For the Kvaser USBcan Light 4xHS to communicate with the host computer, the
correct version of the Kvaser driver and firmware must be installed.
After the driver has been installed on the host computer, the firmware may then be
downloaded and installed on the Kvaser USBcan Light 4xHS.
The latest version of the driver and firmware can be downloaded from
www.kvaser.com/download.
The driver is installed by running the file kvaser_drivers_setup.exe .
The Kvaser USBcan Light 4xHS 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 information on how to upgrade the firmware, see Section 4.5, Updating the
firmware, on Page 14.
3.2 USB connector
The Kvaser USBcan Light 4xHS has a standard USB type “A” connector.
Figure 2: A standard USB type “A” connector.
Kvaser AB, Mölndal, Sweden — www.kvaser.com

Kvaser USBcan Light 4xHS User’s Guide 8 (20)
Connect the device to your computer using any high quality USB 2.0 certified
cable. The maximum USB cable length is 5 m (∼16 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 an effective cable length of up to 25 m (∼82 ft).
As USB cables become longer they are more sensitive to EMI,
because they make a longer antenna that can pick up more
noise. These issues can be mitigated by using higher quality
cables with better shielding. Thicker cables tend to be better than
thin ones, and braided shielding tends to be more reliable than
only foil. Furthermore, longer cables may introduce signal
degradation and timing issues that, if necessary, can be mitigated
using shorter cable segments combined with hubs that amplify
the signal and handle delays on a per-cable basis.
3.3 CAN channels
The Kvaser USBcan Light 4xHS has four CAN Hi-Speed channels in a single
26-pin HD D-SUB CAN connector (see Figure 3). See Section 4.3, CAN
connectors, on Page 12 for pinout information.
Figure 3: CAN connector on Kvaser USBcan Light 4xHS
3.4 Power supply
The Kvaser USBcan Light 4xHS is powered from the USB port.
3.5 LED Indicators
The Kvaser USBcan Light 4xHS has one power LED and one traffic LED for each
CAN channel as shown in Figure 4 on Page 9. Their functions are described in
Section 4.1, Definitions of LED states and colors, on Page 10.
Kvaser AB, Mölndal, Sweden — www.kvaser.com

3.6 Troubleshooting
Use “Kvaser Device Guide” in the Control Panel to verify that the computer can
communicate with the Kvaser USBcan Light 4xHS. If the firmware version shown is
all zeros, there are communication problems. If the LEDs are not flashing or do not
light up at all, check the power supply.

4 Appendices
In this section you will find technical information about the Kvaser USBcan Light
4xHS and its connectors.
4.1 Definitions of LED states and colors
A Kvaser device has two basic types of LEDs; Power and Traffic. These are dual
colored as shown in Table 2. A device with multiple CAN channels has one Traffic
LED for each CAN channel. When the device has more than one channel a space
and digit is added on the label, CAN 1, CAN 2 etc. Low cost products, such as
Kvaser USBcan Light 4xHS, are not equipped with any red Traffic LEDs.
LED Label Color
Power PWR Green/Yellow
Traffic CAN Yellow
Table 2: The different type of LEDs.
The following definitions is used to describe the state of an LED:
Off The LED is off and no light is emitted.
Flash The LED is lit up for a very short time. A single flash may be hard to see
and a continuous set of flashes will look the same as On.
Slow Blink The LED is repeatedly turned On and Off. The On and Off phase is
equal in time.
Fast Blink The LED is repeatedly turned On and Off but with a higher frequency
than Slow Blink. The On and Off time is still equal.
On The LED is constantly emitting light.
Slow Waver This is a variant of Slow Blink but instead of being Off, a second color
is On. This is only possible with a dual colored LED.
Fast Waver The LED is alternating between two colors as in Slow Waver but
using a higher frequency.
Running This means that all LEDs are lit, one at the time, in sequence with every
color available i.e. “Power green->Power yellow->Traffic 1 yellow->Traffic 2
yellow->. . . ”
As an example, "Slow Waver (Green/Yellow)" means that the LED is slowly blinking
by alternating between green and yellow.
Kvaser AB, Mölndal, Sweden — www.kvaser.com

Kvaser USBcan Light 4xHS User’s Guide 11 (20)
4.1.1 Interface mode
The device is in Interface mode when connected to the PC via USB. If the Power
LED is showing a steady green light, the device is in Interface mode and working
correctly. When connected to the computer for the first time, the Power LED will
blink slowly in yellow until the driver is installed and the device has received a USB
configuration.
When in Interface mode, if the Power LED is yellow for an extended period,
something is wrong. Please see Table 3.
The power should never be removed when firmware update is in
progress.
Power LED Traffic LED Description
Slow Blink (Yellow) All off (-) Waiting for USB configuration
Slow Waver (Green/Yellow) Slow Blink(Yellow) Firmware configuration error1
Slow Waver (Green/Yellow) All Slow Blink (Yellow) Power problem2
Table 3: Yellow Power LED shows problems in Interface mode.
Traffic LED Description
Off (-) Idle, no CAN traffic
Flash (Yellow) CAN message received or sent
All Fast Blink (Yellow) Firmware update is in progress
Table 4: Traffic LED shows CAN bus status in Interface mode .
4.2 Technical data
In Table 5 on Page 12 you will find the Kvaser USBcan Light 4xHS’s technical

4.4 CAN bus termination
Every CAN bus must be terminated with a 120 Ohm resistor at each end of the
bus. The Kvaser USBcan Light 4xHS does not contain any CAN bus termination,
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.
To save yourself a lot of trouble, always terminate the CAN
bus properly.
4.5 Updating the firmware
For the Kvaser USBcan Light 4xHS to communicate with the host computer,
compatible versions of the Kvaser CANlib (including driver) and firmware must be
installed.
Kvaser AB, Mölndal, Sweden — www.kvaser.com

Kvaser USBcan Light 4xHS User’s Guide 15 (20)
The latest versions of firmware and drivers can be downloaded for free at
www.kvaser.com/download.
Connect the Kvaser USBcan Light 4xHS to your PC with the USB cable and start
the update.exe application. A window opens showing the Firmware Update
Instructions, read and follow those carefully.
To check the current firmware version, open “Kvaser Device Guide” which can be
found in the Control Panel. Select “Kvaser USBcan Light 4xHS” in the tree view to
the left, and click on the channel. The firmware revision information now appears in
the right half of the window.
