Interface CAN or CAN FD to USB single-channel robust Kvaser U100 with reinforced galvanic isolation

Interface CAN or CAN FD to USB Kvaser U100 (EAN: 73-30130-01173-1) 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.

I. Major features of Interface CAN or CAN FD to USB Kvaser U100

• 20 000 msg/s, each timestamped with a resolution of 100 μs.
• Fully compatible with applications written for other Kvaser CAN hardware with Kvaser CANlib.
• Support for SocketCAN.
• Fully compatible with J1939, CANopen, NMEA 2000® and DeviceNet.
• IP67 rated housing.

II. Sofware

• Documentation, Kvaser CANlib SDK and drivers can be downloaded for free at. www.kvaser.com/downloads.
• 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. Hardware of Interface CAN or CAN FD to USB single-channel robust Kvaser U100

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. 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.

USB connection:

• The USB connector for the Kvaser U100 is 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).

CAN connection:

• The Kvaser U100 has one CAN channel.
• The CAN connector for the Kvaser U100 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 galvanically-reinforced single-channel CAN/CAN FD to USB interface Kvaser U100 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 U100 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 U100 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.

Interface mode:

• The device is in interface mode when connected to a computer via USB. If the status area is presenting a steady white light, the device is in interface mode, working correctly and ready to be used. When connected to a computer for the first time, the status area will Fast Blink with blue light until the Kvaser Drivers are installed and the device has automatically received a USB configuration. The status area will change from white to green when going bus on.

• 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.
• 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.
• The combined area lit by the TX LED bar and the RX LED bar is proportional to the current bus load.
