Forum Post: GUI connection to HVPSFB hardware

Hi,

I downloaded the schematics of the controller and main power boards of the HVPSFB kit.

My question is about the GUI.  

I know that in order to connect the hardware to the GUI a 4 pin SCI to Serial port connection is needed. But looking at the HVPSFB schematics it seems  to me that no 4-pin connector is implemented on to the boards, there is just the USB connector. Moreover, no indication is given in the HVPSFB Kit Overview (QSG-HVPSB-Rev1.1.pdf document) and in SPRABR1 reference document.

How and where the hardware can be connected to the GUI?

Thank you very much
