That's right, now that you mention it....

But there is not much to adjust.
Assignment of the channels, the respective thresholds, baudrate, LSB/MSB, parity, stopbit.
For the demoboard signal it must be set as follows:
9600 baud, LSB first, 8 databits, 1 stopbit, no parity.
I am actually sure that I have set this on the scope, but I can check again on Monday.
