Hi CWS,
Ther is one function in labview, that you can find all the visa resource and it is under "instrument I/O" under "VISA" under "Advance" and you can find "Visa find resource". That function will find all the VISA resource.
For your question, when you repeat step 3, did you see the same setting for your device mean did your setting are the same as the last time you did the configuration? Your divice is using serial, GPIB or others?
