GETTING STARTED GUIDE
NI PCIe-7856
R Series Digital I/O Module for PCI Express, 8 AI, 8 AO, 48 DIO,
1 MS/s AI, Kintex-7 160T FPGA
This document describes how to begin using the PCIe-7856.
Safety Guidelines
Caution Observe all instructions and cautions in the user documentation. Using
the model in a manner not specified can damage the model and compromise the
built-in safety protection. Return damaged models to NI for repair.
EMC Guidelines
This product was tested and complies with the regulatory requirements and limits for
electromagnetic compatibility (EMC) stated in the product specifications. These requirements
and limits provide reasonable protection against harmful interference when the product is
operated in the intended operational electromagnetic environment.

This product is intended for use in industrial locations. However, harmful interference may
occur in some installations, when the product is connected to a peripheral device or test object,
or if the product is used in residential or commercial areas. To minimize interference with
radio and television reception and prevent unacceptable performance degradation, install and
use this product in strict accordance with the instructions in the product documentation.
Furthermore, any changes or modifications to the product not expressly approved by NI could
void your authority to operate it under your local regulatory rules.
Notice Operate this product only with shielded cables and accessories.
Notice The length of all I/O cables must be no longer than 3 m (10 ft).
Preparing the Environment
Ensure that the environment in which you are using the NI PCIe-7856 meets the following
specifications.
Note Refer to the device specifications on ni.com/manuals for complete
specifications.
Storage Environment
Temperature
Operating10 °C to 55 °C
Storage -20 °C to 70 °C
Humidity
Operating 10% RH to 90% RH, noncondensing
Storage 5% RH to 95% RH, noncondensing
Pollution Degree 2
Maximum altitude 2,000 m (at 25 °C ambient temperature)
1For PCI Express adapter cards without integrated air movers, NI defines the local operational
ambient environment to be 25 mm (1 in.) upstream of the leading edge of the card with system
airflow of at least 0.4 m/s (80 LFM) for half length cards and 0.6 m/s (120 LFM) for three-quarter
length cards. For more information about the local operational ambient environment definition for
PCI Express adapter cards, visit ni.com/info and enter the Info Code pcielocalambient.

Unpacking the Kit
Notice 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.
Notice 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.
Verifying the Kit Contents
Verify that the following items are included in the PCIe-7856 kit.

information.
Installing the PCIe-7856
1. Power off and unplug the computer.
2. Access the computer system expansion slots. This step might require you to remove one
or more access panels on the computer case.
3. Locate a compatible slot and remove the corresponding slot cover on the computer back
panel.
4. Touch any metal part of the computer to discharge any static electricity.
5. Insert the PCIe-7856 into the applicable PCI Express system slot. Gently rock the
PCIe-7856 into place. Do not force the device into place.
You cannot install PCI Express devices in PCI slots. PCI Express devices support up-
plugging into a PCI Express slot of higher lane width. For more information, refer to
ni.com/pciexpress.

Verifying Hardware Installation
You can verify that the system recognizes the PCIe-7856 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.
