Is this statement in step #6 incorrect? "Both shunts should be moved to the top 2 pins for the RS232 Cable. If the shunts are moved to the bottom 2 pins, then the USB port is enabled." Shunts should be in the top two pins for USB, correct?

Bharath374 From the picture showed below "6. Attach the serial port cable" in this page, the statement about the shunts' position is wrong. I suppose saying that is referencing the PCB's view.

How are the shunts to be positioned for RS232 Cable instead of USB serial port?

For UART over USB: Short COM_SEL1.1 to COM_SEL1.3 and short COM_SEL1.2 to COM_SEL1.4.

For UART over RS-232: Short COM_SEL1.3 to COM_SEL1.5 and short COM_SEL1.4 to COM_SEL1.6.

Pin 1 is on the edge of the PCB. Pin numbers are assigned in zig-zag fashion, unlike IC's where they are typically counted along an edge.
