Chapter 4 Secure the Terminal
Resetting the Terminal
After a terminal is reset, the application:
• displays the startup screen whether the last displayed screen was secured
or unsecured.
• enables security if it was previously disabled.
• retains changed passwords.
• The current user tag and current user rights tag is cleared when the
terminal resets.
Starting the Terminal in Safe Mode
If the terminal is started in safe mode, security is disabled. When the terminal
is restarted, security is enabled for the application.
Protected Mode Protected mode is a feature that enhances the security of a PanelView 800
terminal, and is available from firmware revision 3.011 onwards.
Protected mode restricts certain operations from being performed on the
terminal while it is running. This reduces the risk that the terminal may be
accessed by unauthorized persons, and disrupt the normal operations of the
terminal and other associated devices or processes.
When the terminal is in Protected mode, the following operations are blocked:
• ControlFLASH™ – Users cannot update the firmware of the terminal.
• Remote configuration change – Users cannot change the network
configuration of the terminal remotely.
• Remote reset – Users cannot reset the terminal remotely.
• Enable/disable ports – Users cannot enable or disable the
communication ports.
Protected mode is automatically disabled when an application is unloaded
successfully. When Protected mode is disabled, the operations listed above can
be then performed as normal.
The terminal automatically enters and exits Protected mode when certain
operations are performed, users do not need to configure any settings.
IMPORTANT
When a ControlFLASH operation is in progress, issuing a reset command
will not reset the terminal until after the firmware update has
completed.
