VCONN signal from one cable plug goes to the VCONN1 pin of the CCG2 at that end and also to the VCONN2 pin of the
CCG2 at the other end of the cable. The same applies to the VCONN signal coming from the other end of the cable. Both
CCG2 devices will get powered: one through VCONN1 and the other through VCONN2. For more details on this
application, refer to

3.6 How to Test CY4502 board
Follow these steps to test the CY4502 board.
1. Connect CY4502 board between a Type-C enabled host (e.g. Laptop, PC) and a Type-C enabled device with a
Type-C receptacle (e.g. Monitor, USB hard disk). One or two LEDs glow, as listed in Table 3-2 , to indicate that the
CCG2 controller(s) and the CY4502 board are powered.
