 ###Flashing binary file:  
-If you want to flash a pre-compiled binary file (like the Release .bin files) you need specialized software and the FTDI cable.  
+If you want to flash a pre-compiled binary file (like the Release .bin files) you need specialized software and the same FTDI cable setup already posted [here](https://github.com/pascallanger/DIY-Multiprotocol-TX-Module/blob/master/docs/Compiling_STM32.md#option-1-flashing-with-tx-powerhighly-recommended).

+1. Connect your 3.3V FTDI cable (USB - TTL serial) to  Multiprotocol serial port (RX,TX,GND pins when flashing with TX power).
+1. Insert first FTDI serial to USB port.Start TX (only if using flashing with TX power method)
