RS232
In RS232 serial protocol, a character is transmitted as a frame of data. The frame
consists of 1 start bit, 5-8 data bits, 0-1 check bit, and 1-2 stop bits. Its format
diagram is as shown in the figure below. RS232 uses "Negative Logic", i.g. high level
is logic "0" and low level is logic "1".
When the Shift key is illuminated, press Home/Menu → Advanced → "RS232"
to open the RS232 waveform parameter setting interface.
1.
Baud Rate: sets the output baud rate of RS232 waveform.
2.
Ampl/HighL: sets the output amplitude/high level of RS232 waveform.
3.
Offset/LowL: sets the output offset/low level of RS232 waveform.
4.
Data Bits: sets the data bits of RS232 waveform to 5, 6, 7, or 8.
5.
Stop Bits: sets the stop bits of RS232 waveform to "1", "1.5", or "2".
6.
Parity Bit: sets the check bit of RS232 waveform to "Odd", "Even", or "None".
7.
Data: sets the data of RS232 waveform. The available value is from 0 to 255.
Please refer to "To Output Basic Waveform" to configure the parameters and
output for the channel.
