LED Behavior on my USB DAQ

Updated Dec 28, 2023

Reported In

Driver

  • NI-DAQmx

Issue Details

  • Why does the green LED blink or not blink on my USB-6008/6009/6501/621x?
  • What does the LED in my device indicate?

Solution

The LED states and their meanings are stated in your device's User Manual:
 

M Series [62xx]

All variants of M Series USB devices have LEDs labeled ACTIVE and READY. The ACTIVE LED indicates activity over the bus. The READY LED indicates whether or not the device is configured. 
 

X Series [63xx]

USB X Series devices have LEDs labeled ACTIVE and READY. The ACTIVE LED indicates activity over the bus. The READY LED indicates whether or not the device is configured.
 

NI Digital I/O (DIO) [65xx]

 

Dynamic Signal Acquisition (DSA) devices [44xx]

  • Each device states the LED information in its own user guide and pinout information. For example: USB-4431 Pinout

Additional Information

The blinking green LED on the USB-6008/6009/6501 indicates that the device is connected to a USB port, that it is receiving power from that connection, and that the device is initialized. It does not indicate the device is malfunctioning in some way. 
 
Likewise, if the green LED on the USB-6008/6009/6501/621x is not blinking, it does not necessarily mean the device is malfunctioning; it may mean that the device is simply not initialized. This could be because the device is connected to a computer that does not have NI-DAQmx installed.
