I have a LAbview 8.6, and i can´t open a file from a Labview 5.1.1

[carlosmayer]

             Hi,

             When i try to open a file(a driver to an OSA from Agilent) appears a error message, saying that the source´s version is too old(5.1.1), when my labview is 8.6.

             Anybody knows something about it?

             Thanks a lot.

Hi. 

I managed to see old vi's made in version 4 with 8.5

First opened with Labview 8.20, saved for previous versions 8.0

Then opened with Labview 8.5..voila

I have Labview 4,  8.20,  8.5,  on different computers.

Hi Carlos,

as told before (and in numerous other threads too) LV8.6 can only open vi from LV6 and up... So you need an older LV version to convert (very) old vis.

I attached the LV8.0 version. There's a missing dll - I hope you have it on your harddisc.

When you look for device drivers it is always a good idea to check the NI website for them...

              Thank you very much, it will be very useful. 

               It worked perfectly.

              Thanks a lot!!!

              and the .dll file was already in my computer.

oh and thanks for the clues about drivers also,

i have done a simple interface for a multimeter, and now the goal is to do one for the OSA,that must be much more difficult....rs

Then mark Gerd's message (#3) as the solution to your question and not your reply #4 where you are thanking him.  You didn't solve your own problem!  Unmark #4 as the solution and mark #3.

                         Hello again.

                        Sorry for marking the wrong post, but i don´t know how to change it.

                        By the way, I am with the same problem again. If anybody has time and a version of Labview able to do this, I would be very grateful. The link is below.

                        Thanks, Carlos Mayer

The manufacturer's web site has a newer version of the driver for that instrument. It's not written all that well, but at least it uses VISA, unlike the VI you uploaded, which uses old GPIB functions. The library the manufacturer provides is in 5.1, which unfortunately you still cannot open in 8.6. Attached is the library in 8.2. For what it's worth, the VI you uploaded in 8.2 is also attached.

                               Hello,

                               Thank you for the help.

                               Yes, I agree with you, these VI´s are a little bit old.

                               But the library,like the other VI, are written to GPÌB connection, and I am trying USB connection.

                               So, by the way, if you have some experience on it, and could give some tip, I would be very grateful.

                               Thanks for updating again,

                                Carlos Mayer.
