Intrument I/O Assistant question

[caunchman]

I have a GPIB-USB-HS hooked up to my laptop and I am trying to use the Instrument I/O assistant to talk to a Aeroflex Spectrum Analyzer.  I pull the Instr I/O assistant out onto the block diagram, it gives me a status bar like it is going into the properties.  Then nothing happens.  I right click and try togo to properties and still nothing.  Am I missing something here? I haven't used the I/O assistant yet so I am unfimiliar with it.  I thought it was similiar to the DAQ wizard.  Oh I am using LabVIEW 7.1 and GPIB 488.2 Ver. 2.42.  Also are there any drivers for the Aeroflex 6825 series that work? The ones I have were for LabWindows, when I converted them over to labview they stopped working....

Thanks

Chris

You mention the 488 driver but what about NI-VISA? Is that installed?

I have the same question Chris ( NI GPIB-USB for LabView I/O Assistant ).

Did it work after installing NI-VISA ?

Thanks,

Peter.

You will definitely need NI-VISA to use the Instrument I/O Assistant.  The version you need depends on the version of LabVIEW you are using.  Here is the compatibility chart: http://digital.ni.com/public.nsf/allkb/CF4279A34F855AB186257B1F00003B82.

Thanks, thats clear enough.

But the link doesn't work, please review.

Just delete the period at the end.

Dennis,

Thanks.

It works now.

The link works or the assistant?

Instead of the assistant, I would suggest you look for an existing driver (Help> Find instrument Drivers) or consider using the VISA functions directly. The assistant adds a lot of overhead and drivers are not that difficult to write. Help is at http://www.ni.com/downloads/instrument-drivers/

The link works, not as yet a GPIB-USD converter.

IO Ass works perfectly - be it not too fast -  with all of my ( 9 ) GPIB gear thru a NI PCI 488 GPIB  card.

Not yet with a GPIB-USB converter since I still have to buy one, thats why I enquired about it on this forum.

I'll try again your advice about  drivers ( but most of the needed ones are unavailable )  and/or try directly using VISA which I didn't dare to do seriously before ( my scarce trials  before failed ).

Thanks again.

Peter.

Dennis,

I made a typo, not 9 but 19 NI HPIB equipment run under my NI488 PCI card + NI 120-A ( + few more GPIB / IEC 625Tektronix, Schomandl en Wavetek ).

All of them run flawlessly under IO Ass.

Now, if I change ( as I understand for speed's sake ? ) to directly using VISA functions, should I write for every of all of my gear VISA separate drivers ?

Or would one " template  " do the job for all of the gear ?

Thanks,

Peter.
