CAN bus data loggers and instrumentation

Data loggers record CAN, CAN FD and LIN networks to their own storage. K-Series modules put thermocouples, voltages and digital signals on the CAN bus, so any logger records them on the same timebase as the vehicle data. K-TC also logs on its own. Each family has its own configuration software.

Start with the job. REXGEN 1 records one classic CAN bus. REXGEN 2 adds CAN FD, LIN and sensor inputs, with an IMU GNSS version. REXGEN Air uploads fleet data over LTE. REBEL LT and REBEL CT run diagnostics on the logger. REXGEN Pro adds edge compute. Answer two questions and the finder recommends one.

A logger sits on the vehicle network and records every frame it sees, with a timestamp, to its own storage. It runs without a PC, wakes on CAN traffic and sleeps when the bus goes quiet. Depending on the model, you collect the data over USB, from an SD card or over LTE.

On the bench, REXGEN 1 and REXGEN 2 work as a J2534 pass-through interface over USB, streaming CAN to your PC tools in real time. In the field, REXGEN Air and REXGEN Pro record to eMMC first, then upload over LTE at a sync rate you set, with configuration and firmware updated over the air.

Every logger records CAN. Depending on the model, it also records CAN FD, LIN, K-Line, analogue and digital inputs, GNSS position and motion, all on one timebase. Every logger decodes SAE J1939. REBEL LT and REBEL CT also run UDS, XCP, CCP and OBD requests. Add K-Series modules for thermocouples, voltages, currents and digital signals.

Every logger records raw frames. A DBC file gives them signal names, scaling and units. Load it into REXDESK for REXGEN or DIALOG for REBEL, and raw frames become named signals; REXDESK exports CSV with the decoding applied. K-CAL generates the DBC for K-Series modules. REXGEN Air can decode each upload with your DBC on arrival.

Engineering teams use our loggers and modules for powertrain calibration and ECU validation, EV battery management and motor control, durability and road load testing, fleet telematics, black-box evidence on haul trucks and cold climate temperature mapping. They work across automotive, electric vehicles, commercial vehicles, agriculture, mining and rail.

Yes. REXDESK configures REXGEN loggers and K-CAL sets up K-Series modules, both free with no licence. DIALOG configures REBEL loggers, with two free versions and two licensed ones. For your own code there is an open XML configuration API and REXLIBRARY, our open source toolkit on GitHub, for file conversion in your applications and cloud functions.

No. Our hardware is open and the firmware is not locked to our software, so it fits the toolchain you already have. K-Series modules transmit standard CAN with a DBC file any tool can decode, and customers already use our hardware with Vector tools, SavvyCAN, MATLAB and Grafana.

Orders ship from our Bedfordshire headquarters, normally within 5 working days, and delivery options are shown at checkout. Influx Technology products are also available through specialist distributors across Europe, Africa, Asia and North America. Orders over 5 units are quoted individually, so ask us for volume pricing.

Every piece of Influx Technology hardware carries a 12 month warranty from the date of delivery. Our engineers help with setup, configuration and data by phone or email. Manuals, pinout guides, drivers and firmware for every product are on docs.influxtechnology.com.
