This USB adapter in combination with the four jumper cables is used to connect e.g. your PiKoder/SSC wRX to a pc for programming the wlan module and the PiKoder's application specific parameters. Please note that this is a standard adapter which is also available on e.g. ebay.
This adapter replaces the obsolete USB cable. The image on the right provides the reference for the connection between the cable and the adapter.
