Front Panel Security Lockout (Executive Modes)
To prevent accidental changes to settings, the System 5 IP with FPC features three
types of front panel security lockout (executive) modes for limiting users’ access to
front panel controls. When a front panel lockout mode is active, functions and
adjustments can still be made through Ethernet or RS-232 control or via an SCP or
hardwired IR control. For details, see chapters four and five.
Modes 2 and 3 can be enabled only via the software or SIS commands via RS-232,
Telnet, or Web browser control. They cannot be enabled via the front panel. All
three modes can be disabled by pressing the Menu and Next buttons
simultaneously for about three seconds.
Disable Menus (executive mode 1) prevents front panel menu access and
configuration via the front panel. The other buttons (Projector, Function/Room,
Input) and volume adjustments are not affected by this setting. This is equivalent
to the 1X SIS command (see page 5-12). This mode can also be enabled or disabled
by pressing the front panel Menu and Next buttons simultaneously for about three
seconds.
Disable all keys (executive mode 2 ) disables all the front panel buttons and front
panel menu access, but volume can still be adjusted. It is equivalent to the 2X SIS
command.
Disable volume (executive mode 3) disables the buttons and the volume knob and
also prevents front panel menu access. The 3X command corresponds to this mode.
