How to trigger more GPIB devices via VISA Assert Trigger

Hello,

Im still beginner and Im looking for solution, which I couldn't find anywhere.

I want to synchronize two devices via GPIB but I have agilent 82357B USB to GPIB so Im using only VISA palette (cos GPIB is not working).

My question is if there is something like TriggerList in GPIB 488.2 ? Or could I trigger more than one device with VISA Assert Trigger?

 

Thanks a lot for your help.

There is no GET available via VISA since each VISA Session has a 1:1 correlation with a device.

 

Lets look into why the 488.2 functions aren't working.  Did you keep NI VISA ar the primary VISA when Agilent IO Library was installed?

Open MAX>>Tools>>VISA Options and find out

Next did you enable the tulip passport?

Hello,

at first I want to apologize for my late response.

You already answer my question but as you said my problem is other (little of topic) I will stay in this tread.

At first my old settings were like this:

VISA option.jpgtulip.jpg

So I change all Agilent to disable.

I was looking for some answer to agilent problem and I found I need to allow in "Agilent connection expert" other 488 programs to use card. So I try but everytime (with or without restart) I get thisAgilent.jpg

However, I try simple command like this with result:

labview_no_GPIB.jpgNI.jpgagi.jpg

And function from VISA palette are still working.

 

Did I miss something? or should I ask in different tread?

Thanks a lot

Clicking the "Allow other 488..." from Agilient CE overwrites the prefered VISA from MAX. 

 

Basically ACE and MAX are alternate hardware configuration tool sets.  use one or the other.  ACE doesn't play well with LabVIEW and NI VISA.  so just use MAX.

Im sorry, Im still little confuse.

How can I use only one? I disable ACE from starting with windows but labview still doesnt work. to disable all processes of agilent causes MAX couldnt load drivers so it cannot find any GPIB.

Do I need to reinstall something or uninstall? Because Im not sure if I can use Agilent card without ACE (where drivers are).
