A note for system managers
You can set the system so that other users must log in and cannot turn off the login
feature. This lets you control who uses the software and which configurations
are used. See “How to set up a controlled system” for details. ▲
If you start OMNIC with the log-in feature turned off, the software loads the
default configuration file. If the file has a password, a prompt asks for the
password. If you enter the correct password, the OMNIC features contained in the
configuration become available for use. If you do not enter the correct password
(you are allowed three attempts), only the Open Configuration and Exit commands
in the File menu become available. Open Configuration lets you use a different
configuration file (see “Opening a configuration” in the “File” chapter for details).
You can then begin working with the software.
Note
You can specify which configuration file is loaded when OMNIC starts by using
Save Configuration As in the File menu. See “Saving a configuration” in the
“File” chapter for details. ▲
When you enter the correct password, it becomes the current password. If you
then open or save a configuration file which uses that password, you are not asked
to enter it. If you will be away from the computer for long, exit OMNIC to prevent
other users from being able to change and save configuration files without
entering the password.
Note
If you accidentally delete all the configuration files from the hard disk, reinstall
OMNIC to establish a default configuration file. ▲
After you install OMNIC, the initial configuration (DEFAULT.CON located in the
Param directory within the OMNIC directory) does not have a password. To give it a
password, use the Password button in the Save Configuration As dialog box.
If you no longer want a configuration file to have a password, use Windows file
management features to overwrite the file with another configuration file that does
not have a password. (You cannot use the Save Configuration As command for this,
as it will not remove a password; it overwrites only the configuration information.)
You can also delete a configuration file by using Delete Files in the File menu. Be
careful not to delete all of your configuration files; OMNIC requires a configuration
file in order to start. See your Windows documentation for more information.
Important
Whenever you assign a password to a configuration, be sure to write down the
password and keep it in a secure location. If you forget the password and do not
have it written down, you will not be able to use that configuration. ▲
Data security
If you have the DS option, special data security features are available in your
OMNIC software. These features provide security for files that contain spectra
(.SPA and .JDX files), experiments (.EXP), macros (.MAC), configurations (.CON)
or options (.OPT) through the use of digital signatures. The visible portion of a
portion of a digital signature consists of a user name, a date and a stated reason
for signing. A digital signature also contains encrypted information that
guarantees that the file has not changed since it was signed and that the file can be
changed only by a user who enters the correct name and password. The data
security features are briefly described below.
