ATV520 recovery via rs232

[teleast]

It seems that my 520 will not boot through sd/usb no matter what, so wanted to try flashing thru usb -> ttl rs232 cable, I have all the files and programs to hand but cannot find a layout of the pins. Ive attached a photo in the hope that someone can guide me. The cable is a prolific 2303HX usb cable.
