    Table 2. LED Indications
    LED Color LED State Controller Status
    POWER Green Solid The cDAQ controller is powered from the V1 input.
    Yellow Solid The cDAQ controller is powered from the V2 input.
    Off The controller is not powered.
    STATUS Yellow 2 flashes every few seconds The controller has detected an error in its software. This usually occurs when an attempt to upgrade the software is interrupted. Refer to the Measurement & Automation Explorer Help for information about installing software on the controller.
    3 flashes every few seconds The controller is in safe mode. Refer to the Measurement & Automation Explorer Help for information about safe mode.
    4 flashes every few seconds The software has crashed twice without rebooting or cycling power between crashes. This usually occurs when the controller runs out of memory. Review your RT VI and check the memory usage. Modify the VI as necessary to solve the memory usage issue.
    Continuously flashing The controller either booted into an unsupported operating system, was interrupted during the boot process, or detected an unrecoverable software error.
    Solid The controller is booting up.
    Red Continuously flashing An internal power supply has failed. Check front-panel I/O and C Series module connections for shorts. Remove any shorts and power cycle the controller. If the problem persists, contact National Instruments.
    Off Normal operation.
    USER1, USER2 Green/yellow USER LEDs are controlled directly from your application. You can define the USER1 and USER2 LEDs to meet the needs of your application. You can use the system hardware property node from the NI System Configuration API to write a state to the USER LEDs.

    (LabVIEW Real-Time Controllers) You can also define a USER LED in LabVIEW Real-Time by using the RT LEDs VI. For more information about the RT LEDs VI, refer to the LabVIEW Help.

    SD ACT Off There is no I/O activity on the SD card in the slot.
    Yellow Flashing The cDAQ controller is performing I/O on the SD card in the slot. Do not remove the SD card while this LED is flashing.
    SD IN USE Off There is no SD card present in the slot or the cDAQ controller has unmounted the SD card from the operating system. It is safe to remove the SD card from the slot.
    Green Solid The SD card in the slot is mounted in the operating system. Do not remove the SD card while this LED is lit.
