I am very interesting in reading the KnowledgeBase article mentioned above, however, I receive a message saying that I do not have permission to read it. Is there another way for me to get to this information? Error -1074130544 or 0xBFFA1190 When Running A Downloaded Instrument Driver.
Thanks in advance!
Don't know if this will help, but check the serial port settings...maybe one of them is off. Also, if it's a USB serial port, sometimes they get reassigned. If you can send it some commands with hyperterm, that might give you a clue.
The KnowledgeBase mentioned earlier in this thread is not currently live right now, that is why you are receiving an error when clicking the link. The relevant information from the article is copied below:
Problem: I have downloaded an IVI Instrument Driver for my instrument. After I install it, I get errors when I open and run the Application Example VI. I get error -1074130544 or 0xBFFE1190 saying that the session handle is not valid. Why am I getting this error?
Solution: In many of the Instrument Drivers, the Application Example VI does not include an Initialize VI. It assumes a valid VISA Session is wired to the VISA Session terminal. If you view the block diagram of the Application Example VI, you will notice that the session is not being initialized (or closed). To correct this problem, place the Initialize, or similar, VI prior to the Application Example VI (and the Close VI afterward) and wire the appropriate terminals. This method should allow you to run this example.
This error can also occur if you have more than one Initialize VI in your program. Only one session can be opened to your instrument at a time, so multiple Intialize VIs will produce this error. For example, if you use the Getting Started VI and then place an Initialize VI in your program, the additional session handle will be invalid.
