Field or control Description
Data Bits Set the number of bits that define a data packet for your RS232 bus.
Source Set the signal source from available analog or digital channels. Available when Data inputs is One.
Threshold Set the threshold level to define a logic high level. Available when Data inputs is One.
Tx Source, RX Source Set the transmitter and receiver signal source from available analog channels. Available when Data
inputs is T
wo.
Tx Threshold, Rx Threshold Set the transmitter and receiver threshold level to define a logic high level. Available when Data inputs
is Two.
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.
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 is 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.
Other bus types
Other serial bus types are available as purchasable options. Once purchased and installed, the new bus types are shown in the Bus
T
ype menu. The serial bus options also add corresponding bus trigger capabilities (when supported) to the Trigger menu. See the Bus
configuration menu on page 127 for links to all serial bus configuration menus.

CAN serial bus configuration menu
Use the CAN bus menu to set up and display a CAN (Controller Area Network) or CAN FD (CAN Flexible Datarate) serial bus waveform.
• To create a new CAN bus waveform:
1. Tap Math Ref Bus > Add New Bus on the Settings bar.
2. Double-tap the CAN badge to open the bus configuration menu.
3. Set the Bus Type to CAN.
• To change the settings on an existing CAN serial bus waveform, double-tap the CAN waveform badge on the Settings bar to open the
configuration menu.
