17 | Hardware Description
If no additional measurement data memory is available, the BR_XETK-S1.0 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.

ECU Interface
The BR_XETK-S1.0 is connected via connectors CON2 and CON4 to the ECU with
two adapter cables (refer to Fig. 3-2 on page 17). The pin definition depends on the
application and the microcontroller type. In general the ECU interface consists 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 3.4 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 BR_XETK-S1.0
and the microcontroller
- 2 ground lines for proper shielding of the ECU interface lines.
