Installing the PCIe-5785 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.

   • a. Module
   • b. System Expansion Slot
   • c. PC

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.

Digital I/O Pinout
The following figure shows the Digital I/O (DIO) connector pinout.

The following table lists the available pins on the DIO connector.

Notice The maximum input signal levels are valid only when the module is powered on. To avoid permanent damage to the PCIe-5785, do not apply a signal to 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 system. 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.

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 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.

Accessing FlexRIO Examples

• FlexRIO examples are available in LabVIEW’s NI Example Finder. Complete the following steps to access the examples by task.

  1. In LabVIEW, click Help » Find Examples.
  2. In the NI Example Finder window that appears, click Hardware Input and Output » FlexRIO.
     Click on an example and refer to the Information window for a description of the example. Refer the Requirements window for a list of hardware that can run the example.
     You can also click the Search tab to search all installed examples by keyword. For example, search for FlexRIO to locate all FlexRIO examples.

• Online examples are also available to demonstrate FlexRIO basics, such as using DRAM, acquiring data from adapter modules, and performing high throughput streaming. To access these examples, search FlexRIO examples in the Search the community field at ni.com/examples.

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.

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.
