Preparation of the USB to Serial converter cable

The Turbine station has a TTL level serial interface which we need to connect to during the upgrade process. For this purpose a USB to Serial converter cable can be used. Recommended cable is TTL-232R-3V3 from Farnell.

This cable needs to be slightly modified as per photo below:

• Pin 1 = Black (GND)
• Pin 2 = Orange (Turbine RX)
• Pin 3 = Yellow (Turbine TX)
