Step 2. Count the Short Flashes
The long flashes are followed by shorter flashes; each short flash lasts
about one-fifth of a second—that is, one-fifth of a second red, one-fifth of
a second off. These short flashes represent the digit in the ones column.
Again, there can be one to nine flashes, which represent the digits
1 through 9. For example, one short flash represents the digit 1 in the ones
column, and nine short flashes represent the digit 9 in the ones column.
Using this method, the
READY
LED flashes the following sequence to
represent status message 11:
<three seconds off> <one long red flash> <one short red flash>
<three seconds off>…
The
READY
LED flashes the following sequence to represent status
message 31:
<three seconds off> <three long red flashes> <one short red flash>
<three seconds off>…
Step 3. Record Your Status Code Number
When you have computed your error message number, write it down and
also note the ON/OFF state of the
ACT/LINK
LED. Have this information
available when calling National Instruments.
CFG RESET Switch
The Configuration Reset (
CFG RESET
) switch is a recessed switch
located beside the power connector on the rear panel.
You can use this switch at power on to reset the unit to its factory settings.
By pressing and holding the
CFG RESET
switch while you power on the
GPIB-ENET/1000, all settings revert to the factory settings as follows:
•
DHCP with Auto IP fallback.
•
Default hostname as printed on the baseplate label.
•
Administrator password is
pass
.
You must press and hold the switch until the
READY
LED flickers yellow.
If you release the switch prior to the
READY
LED flickering yellow, no
change occurs to the network configuration, and the GPIB-ENET/1000
continues to boot normally.
