User’s Guide
Chop When a chop function is supported by a router, the button is a toggle that
enables and disables rapid switching of the selected destination device between
the current source and the preset source. This chop function is used to test
system timing.
The button definition has no fields to configure. Its legend is arbitrary.
Clear Preset Erases preset entries, while leaving the panel in the same mode. We recommend
you use this button because it is a “safety” feature.
The clear preset button has the side effect of switching off ‘Save Preset’ mode.
The button definition has no fields to configure. Its legend is arbitrary.
Default State Returns the panel to its most recent power-up state. That is called the default
state.
The button definition has no fields to configure. Its legend is arbitrary.
Destination Selects a destination.
When you configure a destination button, a drop-down menu appears: ‘Destina-
tion Device’. Choose a device from the list. The ‘None’ entry is merely a
placeholder. Do not choose ‘None’.
The button definition section also presents a “level set filter” drop-down list in
which you can select a level set to reduce the number of sources through which
to browse.
The button legend is the source name, unless you check ‘Use Custom Button
Text’ and assign the button your own text.
Destination
Lock Sets or removes a “lock” on the current destination device. The lock can be
removed only by the user that originally set the lock, or by a panel that has
“Force Release” enabled.
The button definition has no fields to configure. Its legend cannot be changed.
Destination
Protect Sets or removes a “protect” on the current destination device. The protect can be
removed only by the user that originally set the protect, or by a panel that has
“Force Release” enabled.
Note: a protect prevents others from routing to a destination; a lock prevents
anyone
— even the user who issued the lock — from routing to the destination.
The button definition has no fields to configure. Its legend cannot be changed.
Free Source Defines a phantom device that can be used to release or “free” devices on the
data (control) level. A free source is also used with tielines to free the tieline for
others to use. The free source is configured in the Level Set Details page of
NV9000-SE Utilities.
The button definition has no fields to configure. Its legend is arbitrary.
