This section will describe the functions and features of the Kvaser U100-X1.
Figure 1: Kvaser U100-X1
Kvaser U100-X1 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-X1 devices using at least firmware and driver
versions listed in Table 1. For minimum compatible firmware and driver versions of
Kvaser U100-X1 see Table 6 on Page 13.

2.2 Major features of Kvaser U100-X1

Kvaser U100-X1 User’s Guide 7 (21)
In this section you can read more about the CAN channels, power supply and LED
indicators.
The Kvaser U100-X1 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-X1 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 . For
instructions on how to update the firmware, see Section 3.8, Updating the
firmware, on Page 13. 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-X1 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-X1.
The USB connector for the Kvaser U100-X1 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 total USB cable length is 5 m ( 16 ft).

Kvaser U100-X1 User’s Guide 8 (21)
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.
The Kvaser U100-X1 has one CAN channel.
The CAN connector for the Kvaser U100-X1 is the 9-pin J1939-13 Type II
connector (see Figure 3) which has the pinning described in Table 2 on Page 9.

Table 2: J1939-13 Type II pin configuration.
Every CAN bus must be terminated with a 120 Ohm resistor at each end of the
bus. The Kvaser U100-X1 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.
The Kvaser U100-X1 is powered through the USB connector. Make sure the USB
power source can supply enough current (500 mA). If using a USB hub, choose an
externally powered one to be safe.

A Kvaser U100-X1 device has two traffic LED bars where part of each LED bar is
also used as 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 5.
Figure 5: The TX and RX LED bars on the Kvaser U100-X1 include status areas.
Different colors are used for different types of information and different blink
patterns define the current state, see Table 3 and Table 4 on Page 11.
