Operation
Operating Concepts
Panel Lock
A panel lock button prevents changes to the panel settings, especially router crosspoints. When
the panel is locked, the button array becomes blank except for the ‘Panel Lock’ button which
becomes high-tally red.
The button is a toggle: press the ‘Panel Lock’ button to lock the panel. Press it again to unlock
the panel.
The button text is either “Panel Lock” or “Panel Unlock.”
Preset Release
This button removes locks and protects from preset source devices. (If source locks and protects
are not used in your system, this button is not needed.)
If you select a source and someone else has locked or protected the source, your panel will illu-
minate the ‘Preset Release’ button and tell you who locked or protected the source. You can
release it if your panel has “forced release” enabled. (Note that you cannot lock or protect
sources with the NV9642.)
Press the ‘Preset Release’ button to release the source.
The default button text is “Preset Release” but the button can have any legend.
Previous Source
This button presets the previously selected source for the current destination. This function is
useful when you make a route in error.
To recover the previous source, press ‘Previous Source’. When you do, the ‘Take’ button goes
high-tally. Then press ‘Take’ to recover the source.
The default button text is “Previous Source” but the button can have any legend.
Quick Source
A quick source button selects a source and performs an immediate take.
Quick source and source buttons are similar, except that the quick source performs a take. Be
aware of which buttons are quick sources so you do not perform an accidental take.
Normally, the button text is the source’s mnemonic, but the configurer can assign any text to the
button.
Salvo
This button executes a system salvo. A salvo is a pre-defined set of NV9000 commands.
The button text is the salvo’s mnemonic.
Pressing the salvo button puts the panel in “salvo” mode. To confirm that you want to execute
the salvo, press a ‘Take’ button. (You might have to navigate to a ‘Take’ button.) When you press
the take button, the salvo begins executing immediately. Salvos are typically short in duration.
If you want to cancel the salvo before it executes, press the salvo button again.
If you press an ‘Information’ button while the panel is in salvo mode, the panel presents the
salvo commands on the display. You may scroll the display to view the entire salvo.
System salvos are defined in NV9000-SE Utilities. You can review the defined salvos in NV9000-
SE Utilities or communicate with the panel’s configurer regarding the function of any salvos in
your panel configuration.
