2 Introduction
This section will describe the functions and features of the Kvaser U100S.
2.1 Welcome to Kvaser U100S

Kvaser U100S 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 U100S devices using at least firmware and driver
versions listed in Table 1. For minimum compatible firmware and driver versions of
Kvaser U100S see Table 7 on Page 16.

3 Kvaser U100S hardware
In this section you can read more about the CAN channels, power supply and LED
indicators.
3.1 Hardware installation
The Kvaser U100S 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 U100S 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 3.11, Updating the
firmware, on Page 16. 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 U100S 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
U100S.
3.2 USB connection
The USB connector for the Kvaser U100S is a standard USB type “A” connector
(see Figure 2).
Figure 2: A standard USB type “A” connector.
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,
Kvaser AB, Mölndal, Sweden — www.kvaser.com
Kvaser U100S User’s Guide 8 (24)
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 Kvaser MagiSync
Time synchronization is needed to achieve accurate and precise time stamping
between several PC-to-bus interfaces connected to one PC. Since each PC-to-bus
interface uses its on-board clock to set the time stamps.
Kvaser MagiSync is an innovative way to synchronize several different Kvaser USB
interfaces. You do not need external cables - you get instant synchronisation when
you connect the MagiSync enabled Kvaser USB device.
Figure 3: An example setup where all devices are synchronized via MagiSync.
For this to work the Kvaser USB interfaces must reside on the same USB root hub.
If they do not they will not be synchronized, see Figure 3 and Figure 4 on Page 9.
Usually, a computer has a USB controller with one root hub in a computer. If you
use that one, you do not need an external USB hub to get your Kvaser Devices
synchronized. The easiest way to verify the setup is to view Synchronized

Hardware in the Device Tree of “Kvaser Device Guide” in your computer’s control
panel. If all your hardware is placed in one Kvaser MagiSync Group, then you are
ready to go.
When connected correctly, all units are synchronized achieving a high precision
virtual clock accurate to the microsecond.
3.4 CAN connection
The Kvaser U100S has one CAN channel.
The CAN connector for the Kvaser U100S is the 9-pin D-SUB connector (see
Figure 5) which has the pinout described in Table 2 on Page 10.

3.5 CAN bus termination
Every CAN bus must be terminated with a 120 Ohm resistor at each end of the
bus. The Kvaser U100S 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.
3.6 Power supply
The Kvaser U100S is powered through the USB connector.
