The 100 Mbit/s XETK Ethernet interface provides communication with the PC.
4.2
ECU Interface
The BR_XETK-S3.0 is connected via connector CON2 to the ECU with an
adapter cable (refer to Fig.
19). 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
21)
• 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-
S3.0 and the microcontroller
• 5 ground lines for proper shielding of the ECU interface lines.
