slash codes and string inversion

[nash14]

Ok I know I am missing something here but , I need to invert data being sent out of the serial port. The data is normally viewed in HEX and inverting it seems easy enough if viewed in HEX format but the data is incorrect when I check it wit an oscilliscope. It seems related to the slash codes but cannot get my head round how to get the inverted string to be correct ie \55\55\55\55 in the attached vi.

Hi Nash,

you didn't include any default data in your VI…

A slash code of "\55" is the same as an ASCII "U". When I input "AAAA" in your HEX display input I get the correct answer "UU" in the slash code output.

What else do you expect?

Please provide examples (for input and expected output), if you think your VI doesn't work correctly!

knew i was missing something. Labview is converting the HEX to ASCII when valid to display and cause I'm thinking in HEX I missed it.scope probably the stop/start bits.
