TAURKENAM K+DCAN OBD2 Cable Switch FTDI FT232RL

SKU CH-7E46-Z7RGR

Diagnostic cable for BMW E-chassis coding with a hardware switch between K-Line and DCAN protocols

  • Product typeType
  • K-Line and DCAN protocol switching covers all BMW E-series models
  • FTDI FT232RL chipset ensures stable diagnostic communication
  • Cable-only design requires user-sourced software for coding tasks
  • Supports ///M and Alpina variants across the E-chassis range
  • 39-pin OBD2 connector fits factory diagnostic ports

BMW E-Series Diagnostic Cable

The TAURKENAM K+DCAN cable connects a laptop to the OBD-II port on every BMW E-series chassis, including M and Alpina variants. It uses an FTDI FT232RL chip to translate the vehicle’s K-Line and DCAN protocols over USB for coding and diagnostics.

Protocol Switch for EDIABAS Suite

A physical toggle on the cable selects between K-Line and DCAN without unplugging, letting the same lead work with EDIABAS, NCS Expert and ISTA software. The host computer must supply the application and drivers; no software is bundled.

Stable FT232RL Link Under Load

The FT232RL maintains a steady USB-to-serial stream during long coding sessions or multi-module flashes, preventing the buffer drops that can brick a control unit. It requires no external power and draws only the current the port provides.

Questions about this item

Will the FT232RL chipset handle continuous logging without dropping frames?

The cable uses an FTDI FT232RL chipset for USB communication; sustained throughput depends on the host software and vehicle bus load rather than a stated buffer limit.

Does the cable or its switch generate noticeable heat during long coding sessions?

No active components beyond the FT232RL interface are present, so heat output remains low and the plastic housing stays cool to the touch during extended use.

Which laptop port and operating system are required to run the EDIABAS and ISTA toolchains?

A standard USB-A port and a Windows environment capable of running EDIABAS, NCS Expert and ISTA are needed; the cable itself supplies the K-Line and DCAN protocol switching.
