FTDI RX TX lights are reversed

I bought an XBee USB Adaptor (looks exactly this one but I bought from eBay) with an FTDI chip for USB to Serial comms and I noticed that the RX & TX lights are reversed. Don’t worry it can be fixed 🙂

  1. Download the “FT_Prog” program from here.
  2. Extract and install it
  3. Connect your FTDI board to your PC
  4. Run FT_Prog
  5. From the FT_Pro window, click on “Devices” and then “Scan and Parse”
  6. Go this:
  7. Notice C0 & C1 has RXLED#  & TXLED# (your setup might be the other way), swap them around.
  8. Click on “Devices” and then “Program”. This will bring up a new window.
  9. Click the “Program” button. It only takes a few seconds. It will provide a success message at the bottom of the window. Don’t ask me what to do if it shows an error message (sorry!).
  10. Press “Close” and close FT_Prog.
  11. Unplug the board from your PC and plug it back in.
  12. Voila! 🙂

NOTE: Each time you flash the FTDI, the port number changes and the serial number.
