Installing the PCIe Device Driver

NOTE: Your screen may not match exactly with the screen representations shown in this article, depending on your system configuration and the version of driver software being installed.

Before You Begin

Follow the instructions here to insure these prerequisites are met before proceeding with the driver installation:

  • DAQ board must be physically connected to the host PC via PCIe interface.

  • DAQ board must be powered-on and fully booted prior to starting up the PC.

    • (This is to insure that the DAQ enumerates on the PCIe bus during PC startup.)

  • The OCT Host application must be installed on the host PC and a USB connection must be successfully established to the DAQ board.

    • (This is to create the Windows Device Manager "Axsun OCT Devices" category into which the PCIe device driver will also be installed.)

  • The Image Capture Tool application must be installed on the host PC.

Device Driver Installation

  • Wait for Windows OS to launch.

  • Login as a user with administrator privileges.

  • Open Windows Device Manager and confirm the presence of a new unknown device labeled “PCI Memory Controller” in the “Other devices” category:

The DAQ appears as a "PCI Memory Controller" prior to device driver installation.
  • Download the PCIe Device Driver from www.axsun.com/downloads

  • Extract the downloaded .zip archive and confirm the contents of the ..\AxsunPCIeDAQsetup\ directory match that shown here (possibly with a different version suffix):

Contents of the downloaded PCIe device driver archive.
  • Run the batch file installAxsunPCIeDAQwd____.bat to execute the installer script and wait momentarily for installation to occur in the background. The Device Manager tree will refresh several times during the install process, and you will notice a new category “Jungo” with a device titled “WinDriver____” (where ____ is the version number).

  • If Windows Security warning prompts appear, indicate that you trust the software publishers and proceed with the installation.

  • When the driver installation is complete, the Device Manager tree will refresh again and success will be indicated by the “WinDriver____” device listed in the “Jungo” category and “Axsun OCT PCIe DAQ (v____)” device listed in the “Axsun OCT Devices” category:

The PCIe DAQ appears in the Axsun OCT Devices category following device driver installation. The "Axsun OCT Engine" also listed is from the active USB connection.

NOTE: Refer to the DAQ Troubleshooting page if problems occur during installation of the PCIe Device Driver on your system.

  • Confirm that the install script successfully copied wdapi____.dll into the C:\Windows\System32\ directory:

  • Launch the Image Capture Tool and select “PCIe” when prompted to select an interface:

Select the PCIe interface after launching the Image Capture Tool.
  • Unless error message pop-ups indicate otherwise, the PCIe installation was successful and the DAQ board, kernel drivers, user libraries, and GUI Tool are ready for streaming and capturing images. The interface indicator in the Image Capture Tool GUI should show PCIe mode:

Image Capture Tool indicates successful PCIe interface established.
  • Verify the ability to read DAQ FPGA registers via the PCIe interface by pressing the two register READ buttons on the “PCIe” tab of the Image Capture Tool. The register lists should populate with meaningful (i.e. non-zero) values:

Congratulations! You have completed the steps to install the PCIe Device Driver for the Axsun Ethernet/PCIe DAQ board.
