To configure your NI hardware, use Measurement & Automation Explorer (MAX). MAX informs other programs about the NI hardware products in the system and their hardware configuration. MAX is automatically installed with NI-DAQmx.

Note The cDAQ chassis and C Series module(s) are packaged separately.

Refer to the cDAQ-9183 while completing the following assembly steps.

  1. To add the chassis to your software configuration, open NI MAX on your Windows host computer. Expand Devices and Interfaces » Network Devices.
    • If the chassis is on your local subnet, the chassis automatically appears in the list of available devices. Right-click the cDAQ chassis and select Add Device.
    • If the chassis is not on your local subnet, right-click Network Devices and select Find Network NI-DAQmx Devices.
  2. In the Find Network NI-DAQmx Devices dialog box that opens, do one of the following:
    • Check the box that corresponds to your chassis in the Hostname column.
    • If you know the chassis IP address, such as 192.168.0.2, enter it into the Add Device Manually field of the Find Network NI-DAQmx Devices window, and click the + button.
    • Enter the hostname of the chassis. The default hostname is cDAQ918x- <serial number>, where the x represents the last digit of your cDAQ chassis model number.
  3. Click Add Selected Devices.

    The cDAQ chassis icon changes from white to blue/grey, indicating that it is recognized and present on the network.

    1. Discovered, but Not Added to the Network
    2. Recognized, Present, and Reserved on the Network
    3. Recognized, but Disconnected from the Network, Unreserved, or Reserved by Another Host

    If your chassis does not appear in Available Devices, click Refresh List. If the chassis still does not appear, try the following:

    • If you connected the cDAQ chassis directly to your computer, ensure your network card is configured to obtain an IP address automatically, then click Refresh List.
      Note If you connected the cDAQ chassis directly to your computer, the setup time may be longer. Wait 30 to 60 seconds after the STATUS LED turns off, then click Refresh List.
    • Contact your system administrator to confirm that the network is working and that a firewall is not interfering with discovery. For additional troubleshooting resources for the cDAQ chassis, refer to Troubleshooting Chassis Connectivity in MAX.
  4. If the cDAQ chassis is not reserved automatically, select the chassis and click the Reserve Chassis button. Refer to the Reserving the Chassis in MAX section for more information.
  5. Self-test your chassis in MAX by expanding Devices and Interfaces, right-clicking NI cDAQ-<model number>, and selecting Self-Test. Self-test performs a brief test to determine successful chassis installation. When the self-test finishes, a message indicates successful verification or if an error occurred. If an error occurs, refer to ni.com/support and search for the driver name.
  6. Run a Test Panel in MAX by expanding Devices and Interfaces » » NI cDAQ-<model number>, right-clicking your C Series module, and selecting Test Panels to open a test panel for the selected module. Click Start to verify measurement functionality.
    Figure 8. Running a Test Panel

    If the test panel displays an error message, refer to ni.com/support.

    Click Close to exit the test panel.

    Note When in use, the cDAQ chassis may become warm to the touch. This is normal. For instructions on networking to a real-time controller, refer to the Connecting to a Real-Time Controller section.

Reserving the Chassis in MAX

When the cDAQ chassis is connected to a network, multiple users can access the chassis. To perform any DAQ functionality on the C Series modules, including reset chassis and self-test, you must reserve the cDAQ chassis in MAX. The following figure depicts the chassis state icons in MAX: an unreserved chassis or chassis reserved by another host appear with an X and reserved chassis appear as blue/grey. Only one user at a time can reserve the cDAQ chassis.

  2. Recognized, Present, and Reserved on the Network
  3. Recognized, but Disconnected from the Network, Unreserved, or Reserved by Another Host

If the cDAQ chassis was not reserved automatically after it was added (Add Device), you can reserve the cDAQ chassis in MAX by expanding Devices and Interfaces » Network Devices, selecting the chassis, and clicking the Reserve Chassis button. The Override Reservation dialog box appears when you attempt to explicitly reserve a chassis. Agreeing to override the reservation forces the cDAQ chassis to be reserved by the current user.

Troubleshooting Chassis Connectivity in MAX

If your cDAQ chassis is not discovered or becomes disconnected from the network, try the following suggestions.

If the cDAQ-9183 is not listed under Device and Interfaces » Network Device, complete the following steps.
  1. Power off the system.
  2. Ensure that all hardware is correctly installed.
  3. Restart the system.

cDAQ-9183 Connected to a Network or a Remote System is Not Discovered in MAX

  • Verify your network has a DHCP server.
  • Verify the host computer firewall is disabled.
  • Verify the proxy server is disabled.
Note If you are unfamiliar with configuring network devices or are unable to access your cDAQ-9183, contact your network administrator.

cDAQ-9183 Connected Directly to Your Computer is Not Discovered in MAX

For the initial configuration, the host computer must be set to obtain an IP address automatically since the cDAQ-9183 relies on Link-Local addressing to communicate with the host computer. The procedure for configuring your computer to obtain an IP address automatically varies depending on your operating system. Refer to your operating system documentation for instructions.

cDAQ-9183 Connected to a Secondary Network Card on Your Computer is Not Discovered in MAX

  • Verify your secondary network card and Network DAQ device are configured with the correct static IP address and subnet.
  • Verify the host computer firewall is disabled.
  • Verify the proxy server is disabled.
Note If you are unfamiliar with configuring network devices or are unable to access your cDAQ-9183, contact your network administrator.

cDAQ-9183 is Moved to a New Network

  • After moving the chassis to a new network, NI-DAQmx may lose connection to the chassis. In this case, click Reconnect to provide NI-DAQmx with the new hostname or IP address.
  • The cDAQ chassis icon indicates whether it is recognized and present on the network. If a connected chassis appears as disconnected in the configuration tree in MAX, select Self-Test or Reset Chassis. If successful, the chassis icon changes to blue/grey.
