CAN bus data logging device

The CAN bus data logging device serves for logging of communication over the CAN data bus. Each received data packet is given a specific time mark, which shows the precise arrival time of data. The actual time mark is obtained from the internal real time clock (RTC), therefore it is independent of the global system time. Data logging on a common SD card allows further analysis and system monitoring on a PC.

Internal parameters of the CAN bus data logging device itself, such as internal time or data file management, can be controlled through the CAN bus by special commands. The module is typically powered from a monitored system DC bus or any auxiliary power source.

Basic features

• Maximum storage capacity up to 2GB
• Protocol independent
• Standard SD card, FAT filesystem
• Robust chasis
• Battery powered internal real time clock (RTC)
• Wide temperature range
• SW for further data analysis available
• Optional customer design

Typical application

The unit finds its use in all industrial, automotive or aerospace applications where there is a need, for safety and reliability reasons, to store all communication on the system CAN data bus for possible further analysis.

Typical applications:

• Aerospace applications (aircraft, UAV)
• Remote off-line measurement
• Monitoring of mobile devices
• Production line monitoring
• Data logging
• Prototype evaluation
