ECU Interface
The BR_XETK-S1.0 is connected via connectors CON2 and CON4 to the ECU
with two adapter cables (refer to Fig. 4-2 on page 18). 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 4.4 on page 20)
• 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.
