USB-to-CAN interfaces Kvaser U100P (EAN: 73-30130-01174-8) robust, galvanically-reinforced and signal and power isolated, the Kvaser U100 range offers enhanced electrical protection, a vibration, shock and drop-proof housing and high-quality cabling that establishes a new reference in CAN interface design.

I. Major features of USB-to-CAN interfaces Kvaser U100P

  • USB CAN interface.
  • Powered through the USB connector.
  • Supports CAN FD, up to 8 Mbit/s (with correct physical layer implementation).
  • Supports both 11-bit (CAN 2.0A) and 29-bit (CAN 2.0B active) identifiers.
  • Supports silent mode for analysis tools – listen to the bus without interfering.
  • Lightweight robust housing made of glass fibre reinforced polyamide overmolded with TPE.
  • Intuitive LED UI.
  • Reinforced galvanic isolation, design validated with 5000 VAC rms applied for 60 s.
  • Industrial grade temperature range, −40 ◦C to +85 ◦C.
  • 20 000 msg/s, each timestamped with a resolution of 1 μs.
  • Kvaser MagiSync – automatic time synchronization
  • Fully compatible with applications written for other Kvaser CAN hardware with Kvaser CANlib.
  • Support for SocketCAN.
  • Fully compatible with J1939, CANopen, NMEA 2000R and DeviceNet.
  • IP67 rated housing.

II. Software

  • Documentation, Kvaser CANlib SDK and drivers can be downloaded for free at:
  • Kvaser CANlib SDK is a free resource that includes everything you need to develop soſtware for the Kvaser CAN interfaces. Includes full documentation and many program samples, written in C, C++, C#, Delphi, Visual Basic, Python and t programming language.
  • Kvaser CAN hardware is built around the same common soſtware API. Applications developed using one device type will run without modification on other device types.

III. Kvaser U100P hardware

Hardware installation:

  • The Kvaser U100P 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 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. The latest version of the driver and firmware can be downloaded from:
  • The firmware is downloaded and installed directly on the Kvaser U100P 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.

USB connection:

  • The USB connector for the Kvaser U100P is a standard USB type “A” connector.

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.
  • 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.
  • 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.

CAN connection:

  • The Kvaser U100P has one CAN channel.
  • The CAN connector for the Kvaser U100P is the 9-pin D-SUB connector.

CAN bus termination:

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

Power supply:

  • The Kvaser U100P 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.

LED indicators:

  • A Kvaser U100P 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.
  • Different colors are used for different types of information and different blink patterns define the current state.


Information type














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.


The indicator is constantly emitting light.


The indicator is moving and/or increasing/decreasing in size.
