How FlexLogger Connects to Your Hardware

FlexLogger automatically discovers any installed hardware and displays it in the Channel Specification.

If you do not have hardware that is installed, refer to What if I do not have hardware? to learn how to simulate a device.

After creating a project, you can view your hardware in the Channel Specification to begin configuring and managing the signals in your system, such as in the following example system:

Available device channels are beneath the module information. Data acquisition modules show the model name and number along with the slot the modules are installed in. Automotive devices (CAN and LIN) display all available ports, and channels you add are listed beneath the device port information.

After FlexLogger discovers your hardware, you can see the hardware in your project and configure device channels.

What if my hardware does not appear?

If your hardware does not automatically appear in the Channel Specification, try one of the following options.
  • Ensure you are using supported hardware.
  • Confirm your devices are properly connected and powered.
  • Open the Hardware Configuration Utility and confirm your device is listed. If your device is not listed, refer to the Related information to learn how to manage system hardware in the Hardware Configuration Utility. After adding your device in the Hardware Configuration Utility, click Refresh network hardware in FlexLogger to see your reserved device.

What if my hardware appears grayed out?

If your hardware appears as undetected, try one of the following options:
  • Click Reassign to transfer the module project settings to another compatible module in your system.
    Note You cannot undo this operation.
  • Click Delete to remove the hardware from the project.

What if I do not have hardware?

Simulate a USB DAQ from FlexLogger. In the Channel Specification document, click Simulate a USB DAQ. FlexLogger creates a simulated USB-6421 and adds it to your Channel Specification.

You can simulate other NI-DAQmx devices from the Hardware Configuration Utility. For more information, refer to the Related information.
