ETAS
Hardware Description
Configuration Subtype ETK-S6.0A
If the ETK is configured in subtype ETK-S6.0A the ETK uses the AUD-II interface
and the debugger the H-UDI interface. In this configuration ETK and debugger
can work in parallel.
Configuration Subtype ETK-S6.0B
If the ETK is configured in subtype ETK-S6.0B the ETK or the debugger uses the
H-UDI interface. In this configuration ETK and debugger can
not
work in parallel.
If the debugger is connected to the ETK the H-UDI interface is used by the
debugger only. The ETK is automatically disabled.
4.3
ECU Interface
The debug interface lines for the communication between the ETK-S6.0 and the
ECU microcontroller can be configured to use this lines either as an AUD-II inter-
face (ETK-S6.0 configuration type A) or as an H-UDI interface (ETK-S6.0 configu-
ration type B). The configuration is supported by the "ETK Configuration Tool".

Location of the ECU Interface (left: Rev. A, right: Rev. B)
The ECU interface can be flexibly configured for several applications. For a HDC
update, it is not necessary to unmount or disconnect the ETK-S6.0 from the ECU.
The ETK-S6.0 is connected to the ECU via an adapter cable with 26 pins, where
the pin definition depends on the application and the microcontroller type.
For currently supported microcontrollers refer to chapter 7.1.2 on page 38.
4.3.1
AUD-II Interface
In general the ECU interface configured for AUD-II operation (ETK-S6.0 configu-
ration subtype A, see chapter 6.3 on page 33) consists of
• 8 AUD-II lines for the communication between the ETK-S6.0 and the ECU
microcontroller
• 5 JTAG interface lines which are fed to a separate connector for connec-
tion of an external debugger
• 1 reset line which allows the ETK to control the system reset of the ECU
• Voltage and ground lines
Note
Both mechanical versions can be configured to use the ECU interface either as
an AUD-II interface or as an H-UDI interface. The used microcontroller deter-
mines additionally which interface is supported by the ETK-S6.0.
