Hi Hoyo,

only one property inside VISASerialPortConfig isn't supported.

Look inside this function and copy its content to a new VI. Then remove the 2nd last property:

Most probably that "Flow control" isn't supported…

One more comment/suggestion:

Enable the display mode indicator for your string constant. Set it to "\-display". Then append "\n" as it's most likely the TermChar expected by your device…

Actually it says in the error message arg2 so that would be either the baudrate or the Data Bits (not sure atm if that numbering is zero based or not). Thanks to posting a picture where the text is basically to fuzzy to really see much I don't know what constants are used for either of these two values.
