--Press Data and rotate the knob
value vary with the setting in Data Bits. The data value ranges from 0 to 31 if
Data Bits is selected to be "5 bit"; the data value ranges from 0 to 63 if Data
Bits is selected to be "6 bit"; the data value ranges from 0 to 127 if Data Bits is
selected to be "7 bit"; and the data value ranges from 0 to 255 if Data Bits is
selected to be "8 bit".
--Press the Stop Bit softkey to select "1 bit" or "2 bit";
--Press the Even-Odd softkey to select "None", "Odd", or "Even".

Baud Rate:
Press Baud to select the baud rate (equal to specifying a clock frequency) of the
data transmission. The rates available include 2400 bps, 4800 bps, 9600 bps
(default), 19200 bps, 38400 bps, 57600 bps, 115200 bps, 230400 bps, 460800 bps,

or the inner layer of the navigation knob
step (1 bps), or use the outer layer of the navigation knob
baud rate within a relatively larger range. (The greater the rotation amplitude of the
outer layer, the faster the varitations in the values.) The settable range is from 110
bps to 20 Mbps.
Trigger Mode:
