A Universal Serial Bus (USB) connector (P5) provides the onboard debug and programming interface. The debug/programming MCU and associated circuitry are powered through the USB connector, which can also supply the rest of the motherboard by routing the USB Debug Adapter's power through J6. The USB Debug Adapter also provides a data communications interface that can be used when the debug adapter is not debugging or programming a C8051T62x/32x device. Verify that all of the jumper settings match those shown in the diagram. The configuration takes power from the wall adapter and provides the capability to use the UART of the MCU to communicate to the host via the VCP driver. Connect the power supply to the P3 barrel connector, a USB cable from the P5 connector, directly to the PC. The debugger is integrated on to the mother board so no other adapters are required.
