3-43 CrossPoint 450 Plus and MAV Plus Switchers • Operation
Setting the front panel locks (Executive modes)
N In a system with multiple front panel controllers, Extron recommends locking
(setting Lock mode 1) the front panel of BMEs other than BME 0 to prevent
confusion.
The front panel security lockout limits the operation of the switcher system from
the front panel controller. When the switcher is locked, all of the front panel
functions are disabled except for the View-Only mode functions (see "Viewing a
configuration" on page 3-20). Other than in View-Only mode, if the user pushes a
front panel button when the switcher is locked, the RGBHV (CrossPoint 450 Plus)
or Video (MAV Plus) button and the Audio button flash twice and return to their
previous state.
• Lock mode 0 — The front panel is completely unlocked. All front panel
functions are available.
• Lock mode 1 — All changes are locked from the front panel (except for
setting Lock mode 2). Some functions can be viewed.
• Lock mode 2 — Basic functions are unlocked. Advanced features are locked
and can be viewed only.
