GROUND SUPPORT UNIT (GSU)

OPERATION

All  important  settings  are  transmitted  from  the  GSU  to  the  ECU.  The  following  diagram  shows  a  menu
overview.

The input is done by four buttons UP( ), DOWN( ), ESC( ) and Enter( ).

The GSU can be connected during operation to change or show adjustments.

With

-button the menu is scrolled up and down or adjustments are in/ decreased.

With –button inputs can be escaped, without saving adjustments.

With

-button adjustments are saved.
