Serial ETK Interface
The serial 100
Mbit/s ETK-S20.1 interface creates the link to the calibration and
development system. The interface utilizes a 100Base-TX transmission to
achieve a transmission performance of 100
Mbit/s.

Debug Interface
The ETK-S20.1 features a DAP debugging interface connector CON5 (Samtec
16 pin). This connector can be used to attach debug tools (e.g. Lauterbach or
PLS debugger for Infineon TC2D5ED and TC27x-ED).

Location of the Debugger Interface (ETK-S20.1)
By using the debug interface for serial ETK connection, it is not available for
debugging tools anymore. Arbitration mechanisms are required to simultane
-
ously work e.g. with measurement and calibration tools as well as with debug
-
ging tools. The ETK-S20.1 supports a hardware arbitration unit for the DAP
interface. This enables parallel use of tools for debugging and ETAS tools for
measurement and calibration.
NOTE
To ensure stable communication only 100
Mbit cables delivered by ETAS
shall be used.
