Keyboard Lock/Unlock Menu
Utilizing the Keyboard Lock/Unlock feature
allows the user to lock or unlock the front
panel controls for security reasons. While in
the default menu cycle, depressing the cursor
keys
and simultaneously for 2
seconds will either lock or unlock the front
panel controls, depending on the original front
panel lock/unlock status.
____ Once the keyboard is locked it will remain locked even
when power to the RGB 302/304 is removed. To alert
the user upon power up if the keyboard has been
locked, the unit will show the locked message.
Digital Display Sync Processing
Digital Display Sync Processing (DDSP) is a DIP
switch option for all three sync output choices and is
normally set Off. This means that the incoming sync
will be processed, shifted, and then sent to the
presentation display.
If DIP Switch 1 is set On, the sync will pass directly to
the presentation display without being processed and
the horizontal and vertical shift controls will have no
effect on the sync output (the
“Shift Disabled”
message will be displayed).
