Note For complete specifications, refer to the specifications document for
your device at ni.com/manuals.
Installing the Application Soware and Driver
Before installing your hardware, you must install the application soware and
instrument driver. Visit NI FlexRIO Driver Supported Versions for FlexRIO Adapters
and Modules to determine which minimum soware versions you need for your
device. Install the soware in the following order:
1. Install LabVIEW.
Refer to the LabVIEW Installation Guide for installation instructions for
LabVIEW and system requirements for the LabVIEW soware. Refer to the
LabVIEW Upgrade Notes for additional information about upgrading to the
most recent version of LabVIEW for Windows. Documentation for LabVIEW is
available at ni.com/manuals and by selecting Start » All Programs » National
Instruments » LabVIEW » LabVIEW Manuals.
2. Install the LabVIEW FPGA Module.

Refer to the LabVIEW FPGA Module Release and Upgrade Notes for
installation instructions and information about getting started with the
LabVIEW FPGA Module. Documentation for the LabVIEW FPGA Module is
available at ni.com/manuals and by selecting Start » All Programs » National
Instruments » LabVIEW » LabVIEW Manuals.
3. Install FlexRIO Support.
Refer to the FlexRIO Readme on the FlexRIO installation media for system
requirements and installation instructions for FlexRIO Support.
Documentation for FlexRIO Support is available at ni.com/manuals and by
selecting Start » All Programs » National Instruments » NI FlexRIO.
Installing the PXIe-7911/7912/7915
Notice To prevent damage to the PXIe-7911/7912/7915 caused by ESD or
contamination, handle the module using the edges or the metal bracket.
1. Ensure the AC power source is connected to the chassis before installing the
module.
The AC power cord grounds the chassis and protects it from electrical damage
while you install the module.
2. Power o the chassis.
3. Inspect the slot pins on the chassis backplane for any bends or damage prior
to installation. Do not install a module if the backplane is damaged.
4. Remove the black plastic covers from all the captive screws on the module
front panel.
5. Identify a supported slot in the chassis. The following figure shows the
symbols that indicate the slot types.

6. Touch any metal part of the chassis to discharge static electricity.
7. Ensure that the ejector handle is in the downward (unlatched) position.
8. Place the module edges into the module guides at the top and bottom of the
chassis. Slide the module into the slot until it is fully inserted.
9. Latch the module in place by pulling up on the ejector handle.
10. Secure the module front panel to the chassis using the front-panel mounting
screws.
Note Tightening the top and bottom mounting screws increases
mechanical stability and also electrically connects the front panel to
the chassis, which can improve the signal quality and
electromagnetic performance.
11. Cover all empty slots using either filler panels (standard or EMC) or slot
blockers with filler panels, depending on your application.
Note For more information about installing slot blockers and filler
panels, go to ni.com/r/pxiblocker.
12. Power on the chassis.
