LEDs
When the USB-2416 is connected to a computer and in its normal idle state, both LEDs are lit solid green.
Power LED
The Power LED is the top LED on the right side of the USB-2416 housing.
The Power LED blinks when you plug the power supply into the USB-2416, and continues to blink while the
device is being initialized. If it continues blinking for more than ½ second, then there is a problem with the
USB-2416 and you should cycle the power.
If an application issues a blink LED command, then the power LED blinks a few times.
