The READY LED blinks red slowly in a distinct pattern to alert you of

READY LED flashes, and then contact National Instruments.
READY LED signaling can report up to 81 different errors. The errors are
numbered from 11 to 99 and are reported through sequences of READY
LED flashes.

Step 1. Count the Long Flashes

A three-second interval, during which the READY LED is off, separates
each repetition of the sequence. The sequence begins with a series of long
one-second flashes—that is, one second red, one second off. These long
flashes represent the digit in the tens column. There can be one to nine long
flashes, which represent digits 1 through 9. For example, one long flash
represents the digit 1 in the tens column, and nine long flashes represent the
digit 9 in the tens column.
