CL3000 CAN BUS LOGGER with Real-time Clock and WiFi (16 GB)


The CL3000 is a simple-to-use, configurable & powerful stand-alone CAN-bus analyzer. It is both a WiFi data logger with SD card and a wired CAN interface with a real-time clock.



The WiFi CL3000 allows you to access log files remotely across two modes: Access Point mode and Station mode. Further, the CL3000 has a built-in real-time clock with battery backup.

The CL3000 offers simple and user friendly logging of data from a CAN-bus without the use of a computer. Data are stored on a 16 GB SD-card in a simple format so that it can be directly loaded into an analysis tool for post processing. The logged data can be transferred rapidly via WiFi at up to 70 Mbps (9 MB/s) – or via USB.
With Station mode, the CL3000 is able to connect to a WiFi hotspot – e.g. a router, smartphone hotspot or mobile truck hotspot. This makes it ideal for logging CAN bus, J1939 or OBD2 data at scale in e.g. vehicle fleet applications. Simply access each logger while on the network to download the log files – or use our pull scripts to automatize the process.
The device also 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 wired 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 – or via our free CANvas 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.
