Updating Your Firmware
This appendix describes how to update your firmware for your
GPIB-1284CT.
You can use the
ctupdate
utility to update your firmware (
*.mcs
).
As parallel port standards evolve or as the hardware and/or software is
enhanced, National Instruments provides updates of the software and the
firmware.
Caution
Do not update your firmware when your electrical power is unstable, such as
during a weather storm. After you start
ctupdate
, do not power off your GPIB-1284CT
until the update is complete.
To run the
ctupdate
utility, complete the following steps:
1.
At a DOS prompt, type
ctupdate
, an
imagefile.mcs
name, and the
parallel port number, as shown in the following example:
ctupdate 702314b.mcs 1
The utility transfers the imagefile into the EEPROM of your
GPIB-1284CT. The utility then reads back the contents of the
EEPROM to verify that the transfer was successful.
Caution
Do not power off your GPIB-1284CT until the update is complete.
2.
If
ctupdate
reports an error, do not power off your GPIB-1284CT.
Make sure that your GPIB-1284CT is connected to the parallel port
that you typed, and run
ctupdate
again. If errors persist, leave the box
powered on, make a note of the error message, and contact National
Instruments.
3.
After
ctupdate
completes, power off your GPIB-1284CT and then
back on to load the new EEPROM contents.
