can be transmitted within 1 second. Note that start bit, data bit, parity bit and sop bit are regarded as bit. Therefore, baud rate is not
directly equal to valid data transmission rate. Oscilloscope will sample the Bit value according to the set baud rate.
Press the BAUD RATE option key, and the baud rate selection list pops up. Press the BAUD RATE key again to switch between
different baud rates. The available baud rates are: 2400bps, 4800bps, 9600bps, 19200bps, 38400bps, 57600bps, 115200bps,
and customized. The customized baud rate can be provided from 1 to 5000000 (5 million). After selecting the customized baud
rate, the customized value can be adjusted using the Multipurpose knob.
Press the corresponding baud rate display button to
increase the baud rate digit being controlled in order to quickly set to the desired baud rate.
It is recommended to adjust the hardware and software settings of RS232 communication, the transmission condition should be a
distance of under 20m and with speed below 1Mbps. Outside of these ranges and the communication can be disturbed easily or
become unreliable.
If a more detailed communication analysis is needed, the UPO2000CS protocol decoding function can be used. Oscilloscopes
will capture the continuous communication data for you when using this function. The communication contents can be shown on
screen or by the method in the event list.
Bus Setting: Press the PRESS SETTING option key to enter the decoding bus setting.
Bus Status: Press the BUS STATUS option key, and the bus control selection list pops up. The decoding function can be open or closed.
The Multipurpose knob can also be used.
Display Format: Press the DISPL AY FORMAT option key, and four kinds of display methods can be used: hexadecimal, decimal, and binary,
and ASCII. The
Multipurpose knob can also be used.
Event List: Press the EVENT LIST option key, and the decoding events can be open or closed. The knob Multipurpose can also
be used.
Pseudo Square Wave: Press the PSEODO SQUARE WAVE option key, and the pseudo square wave function can be opened and
closed. The
Multipurpose knob can also be used. The pseudo square wave displays 0/1 collected by oscilloscope. The function can
display logic 0 and 1 on the screen under the condition that the input waveform is severely distorted.
Press the NEXT PAGE option key to enter the following settings:
Vertical Position: Press the VERTICAL POSITION option key and rotate the Multipurpose knob to adjust the position of decoding
data on the screen.
Event List Check: When the Oscilloscope is in the state of decoding, the RUN/STOP button is green. At this moment, press the
RUN/STOP and the Oscilloscope will stop refreshing waveform and the button will turn red. The collected data will be stored in the
Oscilloscope. The menu will display decoding data selection list, the button can display the captured times of transmission signals and the
number the selected data.
The selected decoding data will be highlighted green. The Multipurpose knob can select any collected data.
