Labview 8 SE, Mac OS X, Fluke 187

[Russ_Harper]

Hi, I'm new to Labview but not to programming and instrumentation.

I've got a G4 Powerbook with 1Gb and Mac OS 10.4. I've installed Labview 8 SE and it appears to run correctly.

I also have a Fluke 187 DMM which has a USB connection to a computer. I'm trying to use the 187 with Labview.

I found an IVI for the 187 (Fluke 18x series) on the NI Driver board, and have copied the files to the instr.lib directory. This leads
me to believe that Labview can communicate and control the 187.

When I run the 187 example, I am unable to connect to 187 because the Visa resource pick list does not contain any USB entries, only serial entries.

After searching around, I downloaded the NI-DAQmx base package and installed it, hoping it would fix the apparant USB problem.

When I run the NI-VISA configuration utility, it shows 3 Serial resources and 4 USB0 resources.

Any ideas on why NI-VISA doesn't recognize USB?

Thanks,

Russ Harper

I forgot to mention in the initial post that the Driver Wizard shows only PXI/PCI as a bus choice. Both USB and Firewire are greyed out.

Hi Russ,

What version of VISA are you using?  If you aren't using the current version, you should install the latest version.  You need to setup the USB device first before it will show up correctly.  The USB Instrument Control Tutorial discusses this.  If you aren't using the latest version of VISA, updating it could also fix it so that USB is not greyed out on the Driver Development Wizard.

Hope this helps!
