Active USB interface

2 x CAN FD / CAN, 1 x LIN

The USB-to-CAN FD has – depending on the device variant – up to two channels, which support three switchable operation modes: ISO CAN FD, non ISO CAN FD and CAN High-Speed. The automotive variant provides also one LIN channel.


Features and benefits

  • CAN, CAN FD and LIN in one device
  • Cost-effective and extremely versatile 
  • Common driver interface for easy exchange of the PC interface type
  • For industrial and automotive applications
  • Galvanic isolation


The USB-to-CAN FD is available in different variants – compact, automotive and embedded. The compact variant has one switchable CAN / CAN FD channel with a D-SUB 9 plug. The automotive variant has two switchable CAN / CAN FD channels with RJ45 connectors. Adapter cables to D-SUB 9 plugs are included in the scope of delivery. The USB-to-CAN FD embedded is designed without a housing, it comes with a slot bracket and a USB cable for installation into a computer.


LIN (automotive variant)

LIN communications are supported in either LIN master or LIN slave mode. As LIN slave, the interface responds automatically to master requests it receives. The response data is updated through the PC API using a buffer. In master mode, the master calls are processed by the PC application. Incoming LIN messages are forwarded to the application with a timestamp, master request, response, and status information.

Comparison of the different USB-CAN interfaces

HMS offers under the Ixxat brand different USB interfaces for CAN. Besides a one or two channel version and the support of CAN FD and LIN, also an embedded variant for implementation into customer devices is offered. An overview and comparison of the available USB interfaces can be found on the following page:

High performance

By using powerful hardware and connecting over USB 2.0 Hi-Speed (480 MBit/sec), the USB-to-CAN FD interfaces achieve very high data throughput with minimum latency and low power consumption. This allows them to provide the reliable, loss-free transmission and receipt of messages in CAN FD and CAN networks at high transmission rates and bus load. The messages are also timestamped and can be filtered and buffered directly in the USB-to-CAN FD.

Due to its extremely interesting price and compact size, the USB-to-CAN FD interface is ideal for use in series products and in combination with the canAnalyser for development, service, and maintenance tasks.

Its newly developed, rugged housing permits easy customer-specific adaptation (custom design / brand labeling).
