Step 2. Count the Short Flashes
The long flashes are followed by shorter flashes; each lasting about
one-fifth of a second. These short flashes represent the digit in the ones
column. Again, there can be one to ten flashes which represent the digits
0 through 9. For example, one short flash represents the digit 0 in the
ones column, two short flashes represent the digit 1 in the ones column,
and ten short flashes represent a 9 in the ones column.
Using this method, the READY LED flashes the following sequence to
represent status message 11.
<three seconds OFF> <two long flashes> <two short flashes> <three
seconds OFF>...
The READY LED flashes the following sequence to represent status
message 30.
<three seconds OFF> <four long flashes> <one short flash> <three
seconds OFF>...
Step 3. Record Your Status Code Number
When you have computed your status code number, record it on the
forms in Appendix C, Customer Communication, before calling
National Instruments.
Table 4-1 lists some examples of the long and short flashes and the
status codes they report.
