ETAS Hardware Description
XETK-S31.0 - User Guide 17
If no additional measurement data memory is available, the XETK-S31.0 can
alternatively read the data to be measured directly from the microcontroller’s
memory. This process is Triggered Direct Measurement (TDM) with DISTAB13
or DISTAB17.
The 100 Mbit/s XETK Ethernet interface provides communication with the PC.
4.2 ECU Interface
The XETK-S31.0 is connected via connectors CON2 and CON4 to the ECU with
two adapter cables (refer to Fig.
4 - 2 on page 17). The pin definition depends on
the application and the microcontroller type. In general the ECU interface con -
sists of
• 1 ECU voltage line, which is not used for XETK power supply, but only for
detection of the ECU status, therefore the power consumption on this
line is negligible (refer to chapter
4.4 on page 19)
• 1 Reset line which allows the XETK to control the system reset of the
ECU
• 1 Reset line which allows the XETK to monitor the system reset of the
ECU
• 5 Debug line interfaces for the communication between the XETK-S31.0
and the microcontroller
• 2 ground lines for proper shielding of the ECU interface lines.
