SECTION 3 - INSTALLATIONpickeringSOFTWARE INSTALLATIONFirst install the appropriate Pickering PXI switch card drivers by running the installer program Setup.exe, either fromthe CD-ROM supplied, or by downloading the latest version from our website http://www.pickeringtest.com - therecommended method. There are different versions of the Setup program to suit different Windows versions andsoftware environments. Setup is accompanied by a ReadMe file containing additional installation information. Asingle installation covers all cards in the System 40, System 45 and System 50 ranges.When installation completes, the installed drivers’ ReadMe file is offered for display. It can also be displayed laterusing a shortcut on the Programs>>Pickering menu.If you are not a LabVIEW user you should choose the “full” version, and once that has been installed run theLabVIEW Runtime Engine installer via the shortcut on the Programs>>Pickering menu. In the absence of LabVIEWthe Runtime Engine is required to support the Pickering Test Panels application.Page 3.2HIGH DENSITY 2A VERSATILE RELAY MODULE 40-138
pickeringSECTION 4 - PROGRAMMING GUIDESECTION 4 - PROGRAMMING GUIDEPROGRAMMING OPTIONS FOR PICKERING INTERFACES PXI CARDSSoftware drivers are supplied for Microsoft Windows XP/Vista/7 operating systems, with specific support for thefollowing development environments:●●●●●●●●Microsoft Visual Studio (VB, C++, C#)Borland C++National Instruments LabWindows/CVINational Instruments LabVIEW and LabVIEW RTWindows drivers are supplied in the form of Dynamic Link Libraries, which should also be usable in any otherdevelopment environment that supports them.Some recent drivers developed for the LXI platform are capable of addressing both PXI and LXI domains. Suchduality may be of help to users considering future migration from PXI based systems to LXI based systems, orindeed systems containing both PXI and LXI components.Programming for PXIA number of different Windows drivers are available to meet particular system requirements, and should none ofthese be suitable there is also the option of register-level programming. Drivers are generally ‘universal’, handling allmodels in the System 40, 45 and 50 ranges; however some models that are not compliant with the Ivi Swtch classcannot be used with the pi40iv IVI driver. The pipx40 and Pilpxi drivers are also applicable to certain models in theSystem 41 (PXI Instruments) range - see these drivers’ System 41 support list.Please note that this documentation is available in its most up-to-date form as HTML help files, fully hyperlinked foreasy access - both pipx40 and Pilpxi documents are included in the Pipx40vpp software installation.IVI Driver for Windows - pi40ivThe pi40iv IVI (Interchangeable Virtual Instrument) driver supports all Pickering Interfaces PXI switch cards thatare consistent with the Iviswtch class model - as are the great majority of cards in the System 40/45/50 ranges. Itintegrates well with LabWindows/CVI and LabVIEW, and is fully compatible with Switch Executive. It is also usablein general-purpose programming environments such as Visual C++ and Visual Basic.Prior installation of the VISA and IviEngine from National Instruments are required for the correct installation andoperation of this driver.VISA Driver for Windows - pipx40The pipx40 driver conforms to the VISA (Virtual Instrument Software Architecture) standard for programmableinstrumentation. Instrument control environments such as LabVIEW and LabWindows/CVI are based on VISA, andpipx40 support libraries are provided for them.Prior installation of VISA from National Instruments is required for the operation of this driver.Where VISA is available, pipx40 can also be used in general-purpose programming environments such as VisualC++ and Visual Basic. When IVI is not a system requirement this driver will often yield faster operation than thepi40iv driver.Direct I/ODriver for Windows - PilpxiThe Pilpxi driver accesses cards directly, without using the VISA software layer, while offering similar overallfunctionality to pipx40. It is most commonly used in general-purpose programming environments such as VisualC++ and Visual Basic. Operating speed of the VISA and Direct I/O drivers is generally comparable.HIGH DENSITY 2A VERSATILE RELAY MODULE 40-138Page 4.1
