Kvaser's Memorator Light datalogger is designed for troubleshooting CAN-based automotive systems without configuration or software setup. Useful for monitoring intermittent fault conditions, it can be plugged into a vehicle's CAN network and left continuously connected until the fault condition occurs. The small-size device records all real-time CAN bus traffic while the vehicle is running, creating a separate log of what happens just before and after a fault. The gathered data can be easily accessed by connecting the device to a PC. Four externally visible LEDs provide simple indicators of device status, including Power, CAN and Error frame.
