What Does My DAQ LED Color Mean?

The DAQ includes an LED indicator that displays the current status of the device. If the LED color is unexpected, use the following guide to identify the issue.

• Green LED: A green LED indicates a secure connection. The DAQ is operating normally and no action is required.
• Yellow LED: A yellow LED indicates an unstable USB connection. Verify that the USB cable is securely connected and reconnect it if necessary.
• Magenta LED: A magenta LED indicates that communication between the software and firmware has been lost. Restart the software first. If the issue persists, power-cycle the hardware and software components.

These indicators should help you quickly identify the status of your DAQ and troubleshoot common communication issues.
