DCI-CAN1 USB-to-CAN Converter

Robust and compact USB-to-CAN gateway

The DCI-CAN1 (dSPACE calibration interface-CAN1) is an interface that makes it possible to establish a connection from your host PC to the CAN data streams in the vehicle. The DCI-CAN1 transfers CAN messages between the CAN-based devices and the host PC via a universal serial bus (USB).

Application Areas

  • Measuring ECU-internal variables, ECU calibration, diagnostics and ECU flash programming via CCP1), XCP2) on CAN, KWP20003) or UDS4) on CAN, for example.
  • Measuring physical quantities like temperature, pressure, and voltages via CAN-based I/O modules
  • Monitoring the data stream on the CAN bus in ControlDesk® Next Generation
  • Transmitting messages via the CAN bus

Key Benefits

The Controller Area Network (CAN) is an established standard in the automotive industry for exchanging data between electronic control units. The DCI-CAN1 provides a robust, compact interface to the CAN bus via a plug & play USB connection, and features integrated optoisolation and a high-speed transceiver. The DCI-CAN1 is powered directly via USB, so no additional components are necessary to connect to the CAN bus.
