Figure 15.4 Schematic Diagram of RS232 Serial Bus
In RS232, baud rate is used to represent the transmission rate (namely bits per
second) of the data. You need to set the start bit, data bits, check bit (optional), and
stop bits for each frame of data.
• Start Bit: indicates when to output data.
• Data Bit: indicates the number of data bits actually contained in each frame of
data.
• Check Bit: used to check whether the data are properly transmitted.
• Stop Bit: indicates when to stop outputting data.
In the
Decode menu, click or tap the drop-down button of Bus Type to select RS232,
then configure the parameters for RS232 decoding.
