4. Navigate to the folder where the reference design is copied:

cd <dir>\kcu105_control_plane

5. Run the batch script 

quickstart_win7.bat

:

quickstart_win7.bat

6. The screen in 

Figure 3-11

 shows the TRD Setup screen of the GUI. Click 

Proceed

 to test 

the reference design. This step takes you to the Control and Monitoring GUI as shown in
