A Controller Area Network (CAN) is a serial communication system based on the CAN protocol that enables efficient distributed real-time control with high level security. The CAN protocol is especially suited for structuring "intelligent" device networks, as well as for building automatic control environments that contain sensors and actuators within a system or sub-system. The PISO-CM200U is a very powerful and economic solution for an active CAN board, it features two CAN channels and can be applied to a wide range of CAN applications. The 32-bit on-board microcontroller allows the filtering, pre-processing, storage of CAN messages (with a timestamp), and real-time transmission of CAN messages, as well as many other functions.
