ETK-S6.0 Architecture
The microcontroller can communicate with the memories or peripheral compo-
nents of the development ECU.
The ETK-S6.0 is connected to the serial debug and test interface of the microcon-
troller (AUD-II or H-UDI). It converts these interface to the 100 MBit/s serial ETK
interface and extends in this way the length of the connection line.
While the microcontroller accesses the data out of the data emulation memory,
the content of the data emulation memory can simultaneously be modified by
the calibration and development system through the serial ETK-interface. This
process enables adjustments of parameters, characteristic lines and maps
through the calibration and development system. Using an additional measure-
ment data memory area, the ECU microcontroller can send data to the calibra-
tion and development system which receives, buffers and processes this
measured data (DISTAB13).
The 100 Mbit/s serial interface provides communication with the calibration and
development system.
The power supply for the ETK-S6.0 is provided by a switch mode power supply,
to minimize power dissipation.

ETK-S6.0 Subtypes
The ETK-S6.0 contains two independently working subtypes ETK-S6.0A and ETK-
S6.0B. The ETK subtypes are selectable by configuration.
