 On the board are two chips; one is the main USB chip and one is some MAX233/SP231 or similar variant which brings the 5v of the USB logic to the required RS232 voltages. We're now after the 5 FTDI wires:
-|| serial || FTDI colour || DB9 pin ||

-| RTS | green | DB9 - 7 |
+## green
-| RxD | yellow | DB9 - 2 |

-| GND | black | DB9 - 5 |

 Use a multimeter to find the pin on the SP213EH to which the corresponding DB9 pin is wired. Note this on the diagram of the SP231EH chip:
