What Should I Do if the PXIe-7899 Cannot Communicate with XC Devices?

Confirm that the PXIe-7899 detects a connection to the QSFP+ module installed at PORT 0.

  1. In LabVIEW, right-click the block diagram and select NI 7899 User API » Diagnose QSFP.vi.
  2. Double click the Diagnose QSFP VI to view the front panel.
  3. In the resource name field, click the arrow button to browse target devices.
  4. In the Browse RIO Devices window, select the PXIe-7899 as it is identified in NI Measurement and Automation Explorer.
  5. In the LvFPGA bitfile path field, click the folder icon to browse for a compiled LabVIEW FPGA bitfile.
  6. Select a compiled LabVIEW FPGA bitfile from your machine.
    Note For detailed instructions on compiling LabVIEW FPGA bitfiles, refer to the LabVIEW FPGA Module Help available from the Start menu on your development machine or at ni.com/manuals.
  7. On the block diagram, click Run. If the QSFP module present indicator does not turn on, ensure the QSFP+ module is fully seated in PORT 0.
