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.
2| ni.com | PCIe-6593 Getting Started Guide

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.

Recommended Cables (Not Included)
Choose from the following cables to make your high-speed serial connection.
• QSFP28 Active Optical Cable
– 10 m: NI part number 788257-10
• QSFP28 Passive Cable
– 0.5 m: NI part number 788256-0R5
– 1 m: NI part number 788256-01
– 2 m: NI part number 788256-02
Notice When the system is deployed at the upper environmental specification of
the PCIe-6593, standard rated QSFP28 active optical cables may exceed their
operating case temperature range. To ensure the cable case temperature remains
within its operating temperature range, monitor the built-in temperature sensor of the
cable throughout deployment.
Note To convert a QSFP28 signal to a Molex Nano-Pitch signal compatible with
other NI modules, use the SCB-12, NI part number 787419-01.
To purchase high-speed serial cables and the SCB-12, search the NI part number at ni.com.

Installing the Software
You must be an Administrator to install NI software on your computer.
1. Install an ADE, such as LabVIEW or LabWindows™/CVI™.
2. Download the driver software installer from ni.com/downloads.
NI Package Manager downloads with the driver software to handle the installation. Refer
to the NI Package Manager Manual for more information about installing, removing, and
upgrading NI software using NI Package Manager.
3. Follow the instructions in the installation prompts.
Note Windows users may see access and security messages during
installation. Accept the prompts to complete the installation.
4. When the installer completes, select Restart in the dialog box that prompts you to restart,
shut down, or restart later.
Installing the PCIe-6593 Module into PCIe
Chassis
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 module into the slot you selected. Gently rock the module into place without
forcing it.

6. Secure the PCI Express mounting bracket of the module to the computer chassis with two
bracket screws.
Note Because of the high mass of the PCI Express FlexRIO devices,
installing the bracket screws is recommended. Installing the bracket screws
increases mechanical stability and electrically connects the front panel to the
chassis, which can improve signal quality and electromagnetic performance.
7. Connect the 6-pin PCI Express power connector from the power supply to the PCI
Express FlexRIO device.
8. Reinstall any access panels on the computer case.
9. Power on your computer.
Configuring the PCIe-6593 in MAX
Use Measurement & Automation Explorer (MAX) to configure your NI hardware. MAX
informs other programs about which NI hardware products are in the system and how they are
configured. MAX is automatically installed with FlexRIO.
1. Launch MAX.
2. In the configuration tree, expand Devices and Interfaces to see the list of installed NI
hardware.
Note If you do not see your module listed, press <F5> to refresh the list of
installed modules. If the module is still not listed, power off the system, ensure
the module is correctly installed, and restart.
PCIe-6593 Getting Started Guide | © National Instruments Corporation | 5

3. Record the identifier MAX assigns to the hardware. Use this identifier when
programming the PCIe-6593.
4. Self-test the hardware by selecting the item in the configuration tree and clicking Self-
Test in the MAX toolbar.
The MAX self-test performs a basic verification of hardware resources.

Accessing FlexRIO with Integrated I/O
Examples
The FlexRIO driver includes several example applications for LabVIEW. These examples
serve as interactive tools, programming models, and as building blocks in your own
applications. To access all FlexRIO with Integrated I/O getting started examples, complete the
following steps.
1. In LabVIEW, click Help »Find Examples .
2. In the NI Example Finder window that opens, click Hardware Input and Output »
FlexRIO »Integrated IO »Getting Started .
3. Double click Getting Started with FlexRIO Integrated IO.vi.
The FlexRIO with Integrated IO Project Creator window opens.
4. Select the example that corresponds to the name of your FlexRIO module. The
Description window includes a short description of the getting started example for your
device. Rename the project, select a location for the project, and click OK.
The Project Explorer window for your new project opens.
Online examples are also available to demonstrate FlexRIO basics, such as using DRAM,
acquiring data, and performing high throughput streaming. To access these examples, search
FlexRIO examples in the Search the community field at ni.com/examples.

Common FlexRIO with Integrated I/O Examples
In addition to the examples within the FlexRIO with Integrated IO Project Creator, NI
provides several examples that apply to all FlexRIO with Integrated I/O modules to help you
perform common tasks.
The following examples can be found in the NI Example Finder:
•Show All FlexRIO with Integrated IO Hardware.vi queries and displays a
set of hardware properties from all FlexRIO with Integrated I/O devices in a chassis.
•Vivado Export Getting Started Ultrascale.lvproj demonstrates how to
export your LabVIEW FPGA project into Vivado in order to develop your FPGA design
in the Vivado ADE.
•Read-Write Calibration Data.vi demonstrates how to read and write calibration
data and metadata into the storage space of FlexRIO with Integrated I/O devices.
Component-Level Intellectual Property (CLIP)
The LabVIEW FPGA Module includes component-level intellectual property (CLIP) for HDL
IP integration. FlexRIO devices support two types of CLIP: user-defined and socketed.
•User-defined CLIP allows you to insert HDL IP into an FPGA target, enabling VHDL
code to communicate directly with an FPGA VI.
•Socketed CLIP provides the same IP integration of the user-defined CLIP, but it also
allows the CLIP to communicate directly with circuitry external to the FPGA. Adapter
module socketed CLIP allows your IP to communicate directly with both the FPGA VI
and the external adapter module connector interface.
The PCIe-6593 ships with socketed CLIP items that add module I/O to the LabVIEW project.
Synchronizing FlexRIO PCI Express Devices
Using Compact Synchronization and RTSI
(Real-Time System Integration)
You can synchronize the Reference Clocks and triggers of two or more FlexRIO PCI Express
devices and up to five other types of RTSI-supported PCI Express devices.
Sharing Reference Clocks and Triggers with Another
FlexRIO PCI Express Device
Note To synchronize the PCIe-6593 with another FlexRIO PCI Express device,
you need the Compact Synchronization Interface Cable, NI part number 787213-01.
1. Install the PCIe-6593 and another PCI Express FlexRIO device into one PCI Express
backplane.
12 | ni.com | PCIe-6593 Getting Started Guide

2. Insert one end of the Compact Synchronization Interface Cable into the synchronization
connector on each PCI Express FlexRIO device. Ensure the contacts on the cable are
facing the FlexRIO device.

Note To synchronize the PCIe-6593 with a RTSI-supported PCI Express device,
you need the Compact Synchronization Interface to RTSI Adapter, NI part number
787214-01, and a RTSI cable, NI part number 776249-02.
1. Affix the RTSI adapter to the top of the PCIe-6593 using the attached mounting screws.
2. Install the PCIe-6593 and up to five additional PCI Express devices in one PCI Express
backplane.
3. Insert one end of the compact synchronization interface cable into the synchronization
connector on the PCIe-6593. Ensure the contacts on the cable are facing the PCIe-6593.

4. Insert the other end of the compact synchronization interface cable into the closest
synchronization connector on the RTSI adapter.
5. Connect one RTSI female connector on the RTSI cable to the RTSI male connector on the
compact synchronization interface to RTSI adapter on the PCIe-6593. Connect the
remaining RTSI female connectors on the RTSI cable to the male RTSI connectors on the
other PCI Express devices.
