Unpacking the Kit
Caution To prevent electrostatic discharge (ESD) from damaging the device,
ground yourself using a grounding strap or by holding a grounded object, such as
your computer chassis.
1. Touch the antistatic package to a metal part of the computer chassis.
2. Remove the device from the package and inspect the device for loose components or any
other sign of damage.
Caution Never touch the exposed pins of connectors.
Note Do not install a device if it appears damaged in any way.
3. Unpack any other items and documentation from the kit.
Store the device in the antistatic package when the device is not in use.

Installing Software on the Host Computer
Before using the NI PXIe-7868R, you must install the following application software and
device drivers on the host computer.
1. LabVIEW 2017 or later
2. LabVIEW Real-Time Module 2017 or later1
3. LabVIEW FPGA Module 2017 or later
4. NI R Series Multifunction RIO Device Drivers July 2017 or later
Visit ni.com/info and enter the Info Code softwareversion for minimum software support
information.
Installing the NI PXIe-7868R
Caution To prevent damage to the NI PXIe-7868R 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 off 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
NI PXIe-7868R modules can be placed in PXI Express peripheral slots, PXI Express
hybrid peripheral slots, or PXI Express system timing slots.
6. Touch any metal part of the chassis to discharge static electricity.
1LabVIEW Real Time Module is only required when the R Series board is used in a chassis where
the PXIe Controller is running a real-time operating system.

8. 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.
9. Cover all empty slots using EMC filler panels or fill using slot blockers to maximize
cooling air flow, depending on your application.
10. Power on the chassis.
Verifying Hardware Installation for Host Targets
You can verify that the system recognizes the NI PXIe-7868R by using Measurement &
Automation Explorer (MAX).
1. Launch MAX by navigating to Start»All Programs»National Instruments»MAX or by
clicking the MAX desktop icon.
2. Expand Devices and Interfaces.
3. Verify that the device appears under Devices and Interfaces.
If the device does not appear, press <F5> to refresh the view in MAX. If the device does
not appear after refreshing the view, visit ni.com/support for troubleshooting information.

Verifying Hardware Installation for Remote
Targets
You can verify that the system recognizes the NI PXIe-7868R by using Measurement &
Automation Explorer (MAX).
1. Launch MAX on the host computer.
2. Expand Remote Targets in the configuration tree and locate your system.
3. Install LabVIEW Real-Time Module 2017 and NI RIO Device Drivers July 2017 or later
on your Remote Target.
a) Refer to the Installing Software on the Host Computer section for information about
installing software on the host.
b) Refer to the PXI Express Controllers User Manual at ni.com/manuals for
information on installing software on the target.
4. Under Remote Targets, find and expand Devices and Interfaces.
If the device does not appear, press <F5> to refresh the view in MAX. If the device does
not appear after refreshing the view, visit ni.com/support for troubleshooting information.
