TXD , RDX ,  RTS   :    invert signal          RTS ( signal Reset GA144   active low)


          
            1)    Install FT_Prog     (FTDI :     http://www.ftdichip.com/Support/Utilities.htm#FT_Prog ) 
            2)    Plug  USB serial FT232
          






             3)    Run  FT_Prog






        4)      Scan devices :





         The original configuration :     (Save the original configuration before reprogramming FT232)

  



        5)   Open the GA144_configuration   :        C:\Program Files\GreenArrays\EVB001\FTDI\EVB001-A-std-110831.xml








  You can see in Hardware Specific :   Invert RS232 Signals  TXD, RXD, RTS








    6) Program the device :






     7)    !!!   Cycle Port (Force the device to use the new EEPROM contents)











            8)    Configuration USB Serial Port Properties








9)    Unplug and plug again the USB FT232 :


Led Rx and Led Tx  are ON ,   and  RTS  signal is  high.







You can see :         (  arrayforth    :     9 selftest     reset )
RESET    active Low





RX TX Signal   :
