CAN Bus Logger

CAN Bus Protocol Independent Logger

The Diagonal Systems "CAN Bus Logger" has been developed to work as a standalone device, without the need to connect to a PC or smartphone. It has the ability to work reliably and easily. The device is fully configurable and logs the CAN Bus data to a micro SD card (up to 32GB), which is easily accessible.

Our CAN Bus Logger has a real-time clock and is compatible with all CAN Bus networks. It can be configured to accept specific CAN Bus messages (filter configuration) and has some other unique features. The device is the most cost-effective solution available in the market.
