Software

  • Measurement & Automation Explorer (MAX)

Driver

  • PXI Platform Services

Issue Details

When I expand Devices and Interfaces in Measurement and Automation Explorer (MAX), my PXI(e) peripheral modules are not listed or detected in their slot, are not recognized or missing, or appear with a red x.

Solution

Follow the troubleshooting steps below to resolve this issue.
  1. Install PXI Platform Services. If it is already installed, make sure it is a compatible version by cross-referencing the hardware model and operating system compatibility using the following documents: NI PXI Platform Services Hardware Support and NI PXI Platform Services Operating System Support. The version installed can be identified using NI MAX. If the installed version is not compatible:
    • Power down the computer, then the PXI(e) chassis.
    • Power on the computer and install the compatible version of PXI Platform Services.
  2.  Make sure that the compatible device drivers for all peripheral modules are installed by:  
    • Checking the Readme for the peripheral module to identify what drivers are required. Confirm the peripheral module model and operating system are supported.
    • Download the device driver from the NI Driver Downloads Page.
    • For third-party hardware, confirm that the driver supports NI-VISA. If the driver does not, the device will not appear in MAX.
  3. Make sure the peripheral module is inserted in a compatible slot.
  4. If your PXI(e) system uses a controller with the Phar Lap Real-Time OS, make sure you are not booting on safe mode. This OS doesn't load the drivers when it boots on safe mode, and therefore, the devices are not recognized. This configuration is on the BIOS utility of your controller. To know more about this utility and where to find this setting, please go to the user manual of your controller. 
  5. Isolate the issue to the module or slot by:  
    • Testing the non-working peripheral module on another slot of the same type in the PXI(e) chassis.
    • Testing the non-working peripheral module on a new PXI(e) chassis of the same model number. Place the module In the same slot number as the original non-working slot.
    • Testing with another peripheral module of the same module number in the non-working slot.
    • Switching the non-working peripheral module for another module that is already recognized in another slot of the same type.
    • Checking the pins on the module to ensure there are no bent or broken pins.
    • If it is confirmed to be a module issue, follow the steps outlined in DAQ Device or Module Does Not Appear in LabVIEW And/Or MAX.
    • If it is confirmed to be a slot issue:
  6.  If the issue persists after these steps, contact NI support.
