CL2000 CAN BUS LOGGER with Real-time Clock (32 GB variant)


The CL1000 is a simple-to-use, configurable & powerful stand-alone CAN-bus analyzer. It is both a data logger with SD card and a CAN interface with real-time clock.



The CL2000 offers simple and user friendly logging of data from a CAN-bus without the use of a computer. Data are stored on a standard SD-card in a simple format such that it can be directly loaded into an analysis tool for further post processing. The logged data can be transferred to a PC using a standard mini-USB cable and requires no special software.

For advanced users, the device offers a wide range of configuration possibilities, such as message filtering, down-sampling, automatic bit-rate detection, cyclic-logging, heartbeat signal and runtime logging control. Further, recently added features include the ability to transmit up to 20 custom CAN messages (for use in e.g. OBD-II logging) and a new serial interface letting the logger act as a CAN interface for streaming real-time data (incl. integration with Wireshark via CANvas).
The ability to enable message filtering and configure which data fields to log combined with the huge available storage capacity makes the device suitable for long-term stand-alone data logging.
The device configuration can be done on a PC and requires no special software. To simplify the device configuration and to test the CAN-bus connection, the device supports real-time CAN-bus traffic to be displayed directly on a PC using the USB-connection.
The device uses a standard D-sub 9 connector to connect to the CAN-bus and a removable mini-USB cable to connect to a PC. Refer to the product manual for a connector pinout.
