Initiating a software update
from a remote PC
Willtek also offers a tool to update the 4400 software from a PC over the GPIB.
This requires a GPIB interface in the PC. The file to download and a Windows-
based program to perform the software download are available in the download
section on www.willtek.com.
A push on this softkey starts the update routine from floppy
disk. Please follow the instructions shown on the screen of
the 4400.
Notes:
– To return from the update routine without updating, close
the window on-screen with the external mouse and con-
firm the prompt with
Yes.
– NEVER close the window or switch off the 4400 while the
4400 is updating the system (i.e. after copying software
from floppy disk onto the internal hard disk and before the
EPLD update is completed). Otherwise the instrument will
not be usable anymore and needs to go back to the fac-
tory or to a Willtek service center.
This softkey can be used to change from the current software
version to a previously installed version.
First, select the software release to change to on the selection
field of this menu.
Changing to another softkey takes less than one minute on
most systems, but the software must be rebooted.
Before pushing this softkey, consider the consequences: Soft-
ware releases lower than 2.86, for instance, will allow no
return to the current release state.
Note: After installing version 5.10 version 5.00 must be
deleted as switching back to the old version can in this case
cause problems.
If five software versions are already installed on the 4400's
hard disk, it will prompt you to delete an older version first
when you try to install yet another version.
First, select the software release to be deleted on the selec-
tion field of this menu. Before pushing this softkey, consider
the consequences.
After a software release has been deleted, it must be installed
anew if you want to work with it again.
A currently used software version cannot be deleted. If you
want to delete the current version, change to another version
first.
NOTE
The download program requires a National Instruments GPIB card.
