See the UART/RS232 triggering section on page
for detailed instructions.
3 Press the Return to previous menu (up arrow) softkey.
Changing the Bus Configuration settings in the Serial Decode setup also
changes them in the Trigger setup.
4 Press the Bus Config softkey.
a #Bits: Set the number of bits in the UART/RS232 words to
match your target system (selectable from 5-9 bits).
b Parity: Choose odd, even, or none, based on your target
system.
c Baud: Select the baud rate to match the signal in your
target system.
d Polarity: Select idle low or idle high to match your target
system's state when at idle. For RS232 select idle low.
e Bit Order: Select whether the most significant bit (MSB) or
the least significant bit (LSB) is presented after the start
bit in the signal from your target system. For RS232 select
LSB.
In the decode display the most significant bit is always displayed on the
left regardless of how Bit Order is set.
5 Press the Return to previous menu (up arrow) softkey.
6 Press the Base softkey to select the base (hex, binary, or
ASCII) in which decoded words are displayed.
• When displaying words in ASCII, the 7-bit ASCII format is
used. Valid ASCII characters are between 0x00 and 0x7F.
To display in ASCII you must select at least 7 bits in the
Bus Configuration. If ASCII is selected and the data
exceeds 0x7F, the data is displayed in hex.
When #Bits is set to 9, the 9th (alert) bit is displayed
•
directly to the left of the ASCII value (which is derived
from the lower 8 bits).
