8-N-1, ASCII, with “CR” for Send and Receive EOL.
3.
Create your presentation. Note that any built-in serial or GPIO port is treated as a serial device, following the
applicable MediaHub serial protocol.
4.
Export your presentation to a USB or microSD card and insert it into the MediaHub Content port.
