Most folks buy a USB cable made for Nokia phones. I think they are super cheap on Ebay.

I followed the diagram GND’TX’RX’3.3V and want it to come out as a rs232 format I would rather just buy the chip but need to know what chip thanks also note i do not want to hook up to pc the router will be connected to a external device that uses rs232 protacol

The WL-520gU does not operate at RS-232 voltages. I'm pretty sure this is mentioned in the tutorials.

You need a chip (MAX232, etc.) or adapter cable to interface RS-232 signals with the TTL levels used by the router.
