Applications

Multiprotocol CAN Analyzer

Our CAN to USB adapter supports various protocols that are common in automotive applications such as UDS, J1939, OBD2, J2534, etc. Together with the PreciCAN-View tool, this low-cost CAN to USB adapter can capture and display the CAN frames at high-speed. Up to 1200 to 1400 CAN frames per second can be captured and logged in the local PC storage for further analysis. With built-in transmit and receive capabilities, users can not only monitor but also simulate CAN traffic for testing and validation. The PreciCAN-View tool allows easy filtering, decoding, and replay of captured frames, making debugging faster and more efficient. Engineers can also export logs in standard formats for deeper analysis using third-party software. The compact USB form factor ensures portability, while its plug-and-play nature reduces setup time. Designed for both bench testing and in-vehicle applications, this adapter offers a reliable and cost-effective solution for modern automotive development needs.
