Press Endian to select “LSB” or “MSB” and the default is “LSB”.
6. Data Packet Setting
As mentioned before, in RS232, you need to set the start bit, data bits, check bit
(optional) and stop bit of each frame of data. “Start Bit” is specified by the
“Polarity Setting”. The setting methods of other parameters are as follows.
Press Data to set the data width of each frame. It can be set to 5, 6, 7, 8 or
(optional) and stop bit of each frame of data. “Start Bit” is specified by the
“Polarity Setting”. The setting methods of other parameters are as follows.
Press Data to set the data width of each frame. It can be set to 5, 6, 7, 8 or
9 and the default is 8.
Press Stop to set the stop bit after each frame of data. It can be set to 1 bit,
1.5 bits or 2 bits.
Press Parity to set the even-odd check mode of the data transmission. It
can be set to None, Odd or Even.
7. Analog Channel Threshold Setting
To judge logic “1” and logic “0” of the buses, you need to set a threshold for
each analog channel (CH1-CH4). When the signal amplitude is greater than the
preset value, it is considered as “1”; otherwise “0”.

Press MATH Decode Options Auto Thre. to turn the auto threshold on
or off.
When the auto threshold is turned on, the instrument will calculate the center
point according to the current waveform trace automatically as the threshold of
each channel before decording.
When the auto threshold is turned off, you can press Thre.Set to turn the auto
setting menu. Press CH1, CH2, CH3, CH4 and use to set the threshold of
each channel. Press 50% to set the current threshold to 50% of the current
waveform trace.
