-===== Pinout ​of Service-connector "​X800" ​ =====+[[mainboard_service_connectors|Look here for the pinout ​of this plug]].
  
-  * Type: 16-pos, Micromatch +===== Connect an Segger J-Link probe =====
-  * Color: Orange +
-  * Manufacturer:​ "​GARRY"​ +
-  * Partnumber: "MPE 374-1-016"​+
  
-{{artikel:​nav_fx:​mainboard_serviceport_pinout.jpg?​direct|}}+You could use simple Dupond-Wires (Male/​Female) to connect the Segger with the board, but i suggest making a custom cable with the plugs applied. Keep cable length as short as possible to prevent glichtes and chatter.
