DCI-KLine1 USB-to-K-Line Interface

Robust and compact USB-to-K-Line interface

The DCI-KLine1 (dSPACE calibration interface-KLine1), makes it possible to connect an ECU with implemented diagnostic protocol based on K-Line to your ControlDesk PC for ECU diagnostics and ECU flash programming purposes. The DCI-KLine1 forwards the messages and data from and to the host PC.  

  • Robust design for in-vehicle use
  • Integrated optoisolation
  • Supports 12 V and 24 V power supply networks in the vehicle

Application Areas

The DCI-KLine1 is used with ControlDesk to access electronic control units via KWP2000 on K-Line (ISO 14230). It supports ECUs providing single-wire K-Line communication and a fast initialization wake-up pattern (WuP). You can perform ECU diagnostics and ECU flash programming via the DCI-KLine1.

Key Benefits

The DCI-KLine1 comes in the same reliable, robust and compact casing as the DCI-CAN1. Plug & play capabilities via USB provide a quick connection to the host PC. The DCI-KLine1 can be used for ECU diagnostics in passenger cars and commercial vehicles with 12 V and 24 V power supply networks. The integrated optoisolation of the DCI-KLine1 avoids ground loops.
