Ophir LabVIEW VIs FAQ

Note: The Ophir VIs require the VISA library of LabVIEW.

LabVIEW support for USBI

	1. Download Ophir Instrument (516 KB) for LabVIEW support for USBI and run it. 2. This will run the WinZip Self-Extractor and default to unzip the Nova VI's to "C:Program FilesNational InstrumentsLabVIEW 7.0instr.lib". To select a different target folder, press the "Browse" button. 3. Press the "Unzip" button to complete the self-extraction process. 4. Press "Close" to close the session.

To configure windows to operate with Ophir LabView VIs:
At Ophir, we developed USB drivers for use with our USBI PC application. National Instruments USB drivers work in a different manner. Ophir drivers are not compatible with NI VISA communication. NI drivers are not compatible with Ophir's USBI PC application.

The SwapINF utility configures Windows to associate the Ophir device with NIVISA’s usb driver (NIVIUSBK.sys) when LabVIEW is selected. It configures Windows to associate the Ophir device with the appropriate Ophir usb drivers (windrvr.sys) when USBI is selected.

REMINDER: To work with LabVIEW, NI-VISA 3.01 or higher (from National Instruments) must also be installed.

Download and run SwapINF . Follow the on-screen instructions to configure the USB speaking device (USBI, Vega or Nova-II) for LabVIEW or USBI PC work as desired.

Ophir LabVIEW VIs FAQ

• Question: You specify LabView 7.0 or higher. Any issue with LabView 8.2 regarding compatibility with your VI’s?
  Answer: We’ve recently done some in-house tests with LabVIEW 8.2 and the USBI VI’s seem to be compatible.
  We’ve also had other customers working with our VI’s in LabVIEW 8, so far with no clear issue that we know.
  In fact, LabVIEW usually offers/suggests that it will automatically update the VI’s when opened with a newer version of LabVIEW.

• Question: I've followed all of the instructions and receive the error "1301" etc.
  Answer: Device responses take the form 1.234 (a period distinguishes between the integer and fractional part of a real number). This may not match the settings of the computer upon which the VI is running. For example, many European countries use a comma (",") in place of a period (1,234). This causes the LabVIEW VI to not "understand" the devices's response.
