Target Connector Type
Target Connector Placement
The adaption uses one 40 pin Samtec connector.
We recommend to place the even numbered pins at the PCB border side (flex cable won't be twisted).
Pinout
 Debug Signals
The pinout of the 40 pin Samtec connector optionally includes the debug signals.
The Preprocessor has a 20-pin connector to plug in the Debug Cable.
For better signal quality this converter split of the debug signals from the 40 pin SAMTEC HSSTP connector on target
to the 20-pin standard debug header.
