3 Kvaser U100P-X2 hardware
In this section you can read more about the CAN channels, power supply and LED
indicators.
3.1 Hardware installation
The Kvaser U100P-X2 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 U100P-X2 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 3.9, Updating the
firmware, on Page 14. 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 U100P-X2 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
U100P-X2.
3.2 USB connection
The USB connector for the Kvaser U100P-X2 is a standard USB type “A” connector
(see Figure 2).

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 U100P-X2 User’s Guide 8 (22)
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 host computer-to-bus interfaces connected to one host computer.
Since each host computer-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 U100P-X2 has one CAN channel.
The CAN connector for the Kvaser U100P-X2 is the 5-pole M12 plug (see Figure 5)
which has the pinning described in Table 2.

3.5 CAN bus termination
Every CAN bus must be terminated with a 120 Ohm resistor at each end of the
bus. The Kvaser U100P-X2 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 U100P-X2 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.
