In the UART Settings menu, 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 in the UART Bus Config menu, the
9th (alert) bit is displayed directly to the left of the ASCII
value (which is derived from the lower 8 bits).
7
Optional: Press the
Framing
softkey and select a value. In the
decode display, the chosen value will be displayed in light
blue. However, if a parity error occurs the data will be
displayed in red.
8
If the oscilloscope is stopped, press the
[Run/Stop]
key to
acquire and decode data.
You can use the horizontal
Zoom
window for easier navigation of the acquired data.

NOTE
If the setup does not produce a stable trigger, the UART/RS232 signals may be slow enough
that the oscilloscope is auto-triggering. Press the
[Trigger]
key, then press the
Mode
softkey
to set the trigger mode from
Auto
to
Normal
.
