488

[b_lee]

So here is my problem... I am working with an old device that is only capable of using 488 and not 488.2 so I was wondering how I can ensure that my NI PCMCIA-GPIB card and LabView are only sending 488 commands? I also have the problem of Labview not being able to see my device when I try to use VISA sessions. Without being able to see the device I am somewhat lost since I have never encountered this problem.

You can use the 488 commands (i.e. GPIB Write and GPIB Read) but I don't understand your comment about LabVIEW not being able to see your instrument. LabVIEW with the VISA Resource Name control 'sees' whatever MAX has detected. Are you saying that the VISA Resource Name does not list your instrument or are you having a different problem?

[b_lee]

Yes. It doesnt list my instrument so it is not possible for me to send it the read and write commands.

[Dennis_Knutson]

That's a big problem since the instrument detection in MAX uses some pretty low level GPIB functions (not VISA at all) and if you can't detect it in MAX, I doubt that you would be able to use the non-VISA functions either. There are some property settings for the GPIB controller that can be modifed such as bus timing so you could check those.
