GPIB-ENET for MacOS
not on the actual Internet or you want to update the firmware yourself,
you can execute
Update
locally. In either case, pay close attention to
the GPIB-ENET READY LED, which reports important status codes.
Although you should update your firmware as needed, the number of
times you can do so is limited. Therefore, you should update the
firmware only when necessary. Also, notice that there is a time period
of about two seconds when the GPIB-ENET runs exclusively in volatile
RAM memory with the EEPROMs erased. If the box loses power during
this time, it is no longer usable and must be returned to National
Instruments for repair. If you are not comfortable with this procedure,
call National Instruments for assistance.
Caution:
Because of the potential loss of EEPROM information, do not attempt to
update the firmware when your electrical power is in danger; that is,
during a weather storm or similar situation. Once you have started the
update process, do not switch off power to your GPIB-ENET until you see
and record the flashing READY LED pattern.
The following procedures describe how to update the firmware.
1.
Power off the GPIB-ENET and set DIP switch 7 to the ON position.
2.
Power on the GPIB-ENET and wait for the READY LED light to
remain steady without flashing.
3.
Execute the
Update
application, which is located in the
Ethernet
folder.
a.
Enter the IP address of the GPIB-ENET in the space provided,
and click on the Done button to continue.
b.
Select a GPIB-ENET EEPROM file to use as the firmware
image.
After the GPIB-ENET receives the firmware image, the
Update
utility reports the status of the download. At that point,
the network connection is closed. Therefore, the utility does
not report the success or failure of the actual EEPROM
programming, but only of the transfer of the firmware image.
c.
After the connection terminates, the GPIB-ENET attempts to
program its EEPROMs. Wait for the READY LED to begin
flashing, which signals that the procedure is complete. Do not
power off your GPIB-ENET before you see and record the
flashing READY LED pattern.
If the programming is successful, the READY LED signals a
status code of 00, signified by one long flash and one short
!
