UART/RS232 Serial Decode
To set up the oscilloscope to capture UART/RS232 signals, see "Setup for
UART/RS232 Signals" on page 407.
To set up UART/RS232 serial decode:
1 Press [Serial] to display the Serial Decode Menu.
2 Press Settings.
3 In the UART/RS232 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.
If the setup does not produce a stable trigger, the UART/RS232 signals may be slow
enough that the oscilloscope is AutoTriggering. Press the [Mode/Coupling] key, then
press the Mode softkey to set the trigger mode from Auto to Normal.
To display UART/RS232 serial decode, see "UART/RS232 Serial Decode" on page 411.
For UART/RS232 triggering setup see "UART/RS232 Triggering" on page 409.
