RS232 serial bus menu fields and controls.
Field or control Description
Display Turns on or off displaying the bus on the Waveform view.
Label Enter a label for the bus. The default label is the selected bus type.
To enter label text, double-tap the field and enter label using the virtual keyboard, or tap the
field and enter text from an attached keyboard.
Position Sets the vertical position of the bus waveform. The default position is vertically centered in a
slice (in Stacked mode), or center screen in Overlay mode. The unit of position is screen
divisions.
Set to 0 Sets the vertical position to 0 divisions (centered vertically in a slice or on the screen.
Bus Type Set to RS232.
Bit Rate Sets the data bit rate.
To enter a custom bit rate, tap Custom and enter the custom bit rate in the Custom Rate input
box.
Source Set the signal source from available analog or digital channels.
Threshold Set the threshold level to define a logic high level.
Polarity Select the polarity to match the RS232 bus being acquired. Use Normal polarity for
RS-232 signals, and Inverted polarity for RS-422, RS-485, and UART buses.
Data Bits Set the number of bits that define a data packet for your RS232 bus.
Parity Set the parity to match the RS232 bus being acquired.
Packet View Set to On to show decoded packet level information on the bus waveform.
End of packet select the appropriate end of packet value to match the RS232 bus being acquired.
Available when Packet View = On.
Display Format Sets the waveform view to show just the decoded bus information, or the decoded bus plus the
source signal waveforms.
Decode Format Sets the decode format used to display the bus information. Formats are Hex, Binary, and
ASCII.
