LEDs
When the OMB-DAQ-2416-4AO is connected to a computer, 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 OMB-DAQ-2416-4AO housing.
The Power LED blinks when you plug the power supply into the OMB-DAQ-2416-4AO, and continues to blink while the device initializes the hardware. If it continues blinking for more than ½ second, then there is a problem with the OMB-DAQ-2416-4AO and you should cycle the power.
If an application issues a "blink LED" command, then the power LED blinks a few times.
Activity LED
The (USB) Activity LED is the bottom LED on the right side of the OMB-DAQ-2416-4AO housing. It blinks rapidly when both the USB cable and external power cables are plugged in. It continues blinking rapidly while the device is connecting to the computer, and then turns solid.
Whenever the device receives a USB command, the Activity LED blinks off and then returns to solid green. When an analog in or analog out scan is running, the Activity LED blinks continuously.
