2 Introduction
This section will describe the functions and features of the Kvaser U100.
2.1 Welcome to Kvaser U100
Figure 1: Kvaser U100 with D-SUB CAN connector
Kvaser U100 is a small, yet powerful, CAN to USB interface. It provides real-time
transmission and reception of standard and extended CAN messages on the bus
with a high timestamp precision, and is compatible with applications that use
Kvaser’s CANlib.
This guide applies to Kvaser U100 devices listed in Table 1.
Device Product Number
Kvaser U100 73-30130-01173-1

2.4 Additional software and documentation
The Kvaser CANlib SDK includes everything you need in order to develop software
applications interacting with Kvaser CAN hardware. The SDK contains full
documentation and many sample programs, written in C, C++, C#, Delphi, Python
and Visual Basic. Kvaser CAN hardware is built around the same common
software API. Applications developed using one device type will run without
modification on other device types.
The latest versions of documentation, software and drivers can be downloaded for
free at www.kvaser.com/download.

3 Kvaser U100 hardware
In this section you can read more about the CAN channels, power supply and LED
indicators.
3.1 Hardware installation
The Kvaser U100 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 U100 to communicate with the host computer, a compatible version
of the Kvaser driver and firmware must be installed.
The driver is installed by running the file kvaser_drivers_setup.exe . For
instructions on how to update the firmware, see Section 4.8, Updating the
firmware, on Page 15. The latest version of the driver and firmware can be
downloaded from www.kvaser.com/download.
The firmware is downloaded and installed directly on the Kvaser U100 and the
driver is installed on the host computer. After the driver has been installed on the
host computer, the firmware may then be downloaded and installed on the Kvaser
U100.
Device Firmware Windows driver Linux driver
Kvaser U100 v3.22.578 v5.34 (kcany) v5.34 (mhydra)
Table 2: Kvaser U100 devices and requirements on minimal version of firmware and
drivers.
3.2 USB connection
The Kvaser U100 is connected to a PC using USB. See Section 4.5, USB
connector options, on Page 13 for more information.
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.

Kvaser U100 User’s Guide 8 (22)
3.3 CAN channels
The Kvaser U100 has one CAN Hi-Speed channel. See Section 4.6, CAN
connector options, on Page 14 for more information.
3.4 Power supply
The Kvaser U100 is powered through the USB connector.
3.5 LED Indicators
The Kvaser U100 has one Tx LED Bar and one Rx LED Bar as shown in Figure 2
on Page 9, Figure 3 on Page 10. Their functions are described in Section 4.2,
Definitions of Information types and States, on Page 11.
3.6 Troubleshooting
Use “Kvaser Device Guide” in the Control Panel to verify that the computer can
communicate with the Kvaser U100. If the firmware version shown is all zeros,
there are communication problems. If the LED Bar or the status indication is not
flashing or does not light up at all, check the power supply.

4 Appendices
In this section you will find technical information about the Kvaser U100 and its
connectors.
4.1 Definitions of LED states and colors
The Kvaser U100 has one Tx LED Bar and one Rx LED Bar. Each LED Bar has a
status area, the Tx LED Bar has a status area towards the USB end of the bar, and
the Rx LED bar has a status area towards the CAN end of the bar. This is shown in
Figure 2.
Figure 2: The Tx and Rx LED bars on the Kvaser U100 includes status areas.
The Tx LED bar lit area grows from the USB end of the LED bar towards the CAN
end of the bar as CAN Tx traffic is increased. Likewise, the Rx LED bar lit area
grows from the CAN end of the LED bar towards the USB end of the bar as the
message rate of the received traffic is increased, see Figure 3 on Page 10. In this
example the unit is transmitting data, which shows a yellow Tx status area. No
CAN traffic is received and as such the Rx status area is green.
The total size of the LED bars are indicating the current bus load, e.g. Figure 3 on
Page 10 shows only receiving CAN messages at 50% bus load. Figure 4 on
Page 10 shows two different bus load conditions. The image on the left shows the
unit transmitting and receiving data corresponding to 50% bus load in each
direction for a total of 100% bus load. The image on the right shows the unit
transmitting data corresponding to 100% bus load.
Kvaser AB, Mölndal, Sweden — www.kvaser.com

Kvaser U100 User’s Guide 10 (22)
Figure 3: The Tx LED bar lights up from the USB side to the CAN side of the unit,
while the Rx LED bar lights up from the CAN side to the USB side of the unit.
Figure 4: The total size of the LED Bars is proportional to the bus load. Both
images indicate a bus load of 100%.

4.2 Definitions of Information types and States
A Kvaser U100 device has two traffic LED bars where part of each LED bar is also
used as a status area. Different colors are used for different types of information
and different blink patterns define the current state, see Table 3 and Table 4.
Color Information type
Yellow Traffic
Green Power
Red Error
White Alert
Blue System
Table 3: Different types of information.
State Definition
Off The indicator is off and no light is emitted.
Slow Blink The indicator is repeatedly turned on and off. The on and off phases are equal in
time.
Fast Blink The indicator is repeatedly turned on and off but with a higher frequency than Slow
Blink. The on and off times are still equal.
On The indicator is constantly emitting light.
Dynamic The indicator is moving and/or increasing/decreasing in size.
Table 4: Definitions of the indicator states.
4.3 Interface mode
The device is in interface mode when connected to the PC via USB. If the status
area is presenting a steady green light, the device is in interface mode and is
working correctly. When connected to the computer for the first time, the status
area will Fast Blink with blue light until the Kvaser Driver is installed and the device
has automatically received a USB configuration. Table 5 summarises the
information shown in interface mode.

4.7 CAN bus termination
Every CAN bus must be terminated with a 120 Ohm resistor at each end of the
bus. The Kvaser U100 does not contain any CAN bus termination, because their
Kvaser AB, Mölndal, Sweden — www.kvaser.com

Kvaser U100 User’s Guide 15 (22)
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.
4.8 Updating the firmware
For the Kvaser U100 to communicate with the host computer, compatible versions
of the Kvaser CANlib (including driver) and firmware must be installed.
The latest versions of firmware and drivers can be downloaded for free at
www.kvaser.com/download.
Connect the Kvaser U100 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 U100” 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.
