Note For complete specifications, refer to the specifications document for

your device at ni.com/manuals.

Installing the Application Soware and Driver

Before installing your hardware, you must install the application soware and

instrument driver. Visit NI FlexRIO Driver Supported Versions for FlexRIO Adapters

and Modules to determine which minimum soware versions you need for your

device. Install the soware in the following order:

1. Install LabVIEW.

Refer to the LabVIEW Installation Guide for installation instructions for

LabVIEW and system requirements for the LabVIEW soware. 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.

ni.com

PXIe-7911/7912/7915 Getting Started

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.

4. PXI Express System Timing Slot

5. PXI Express Peripheral Slot

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.
