Installing the PCIe-5785
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.

the device when the module is powered down.
Notice Connections that exceed any of the maximum ratings of any connector on
the PCIe-5785 can damage the device and the chassis. NI is not liable for any
damage resulting from such connections.
Configuring the PCIe-5785 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 Support.
1. Launch MAX.
1MGTs are available only on devices with KU040 and KU060 FPGAs.
PCIe-5785 Getting Started Guide | © National Instruments | 7

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.
3. Record the identifier MAX assigns to the hardware. Use this identifier when
programming the PCIe-5785.
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.
FlexRIO Examples
FlexRIO includes several example applications for LabVIEW. These examples serve as
interactive tools, programming models, and as building blocks in your own applications.

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-5785 ships with socketed CLIP items that add module I/O to the LabVIEW project.
PCIe-5785 Getting Started Guide | © National Instruments | 11

Making a Measurement with LabVIEW
1. Launch LabVIEW.
2. Select Help»Find Example.
3. Open the example VI that you want to use by selecting Hardware Input and Output»
FlexRIO.
4. Follow any setup, configuration, and execution instructions in the VI.
Synchronization
You can use the compact synchronization interface cable (part number 769693-01) to share a
Reference Clock and triggers between the PCIe-5785 and another PCI Express FlexRIO
device. You also can use the compact synchronization interface to RTSI adapter (part number
147008A-01L) to synchronize the PCIe-5785 with a PCI Express device that supports
synchronization using RTSI.
