10.1 User Groups
The SC-COM distinguishes between the "user" and "installer" user groups. The distinction is made via different passwords.
If the password is the same for both user groups, you will be logged in automatically as installer.
To prevent two users from making changes at the same time, only one user can ever be logged into the SC-COM at a
time.
10.2 XML File custom.xml
10.2.1 Structure of the XML File custom.xml
You can upload your own system and network settings via the XML file custom.xml. The SC-COM checks the file for
validity and accuracy of the entered values and takes over the settings when you reset the SC-COM.
