relatively smaller step or turn the outer knob of the navigation knob to
adjust the baud rate at a relatively larger step. The adjustable range is from
110 bps to 20000000 bps (20 Mbps).
Note: The larger the rotation amplitude of the outer knob of the navigation
knob is, the faster the variation of the value will be. When you need to
adjust the baud rate within a relatively larger range, this function can help
you quickly finish the setting.
Press Polarity to set the polarity of data decoding to "Normal" or "Invert" and
the default is "Normal".
Normal: use negative logic; namely, high level is logic "0" and low level is

logic "1".
Invert: use positive logic; namely, high level is logic "1" and low level is logic

"0".
Press Endian to select "LSB" or "MSB" and the default is "LSB".
LSB: Least Significant Bit; namely the less significant bit of the data are

transmitted first.
MSB: Most Significant Bit; namely the more significant bit of the data are

transmitted first.
LSB
The start bit is used to denote when the system starts to transmit data. It is
