4. Configuration
Button Definitions
Chop When a chop function is supported by the 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.
Clear Preset Erases preset entries, while leaving the panel in the same mode. This button is rec-
ommended as a “safety” feature.
The clear preset button has the side effect of switching off ‘Save Preset’ mode.
Default State Returns the panel to its most recent power-up state. That is called the default state .
Destination Selects a destination.
When you assign a destination button, a drop-down menu appears: ‘Destination
Device’. Choose a device from the list.
The ‘None’ entry is merely a placeholder. Do not choose ‘None’.
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.
In MD mode, an “L” appears next to the destination when it is locked.
In X-Y mode, an “L” appears next to selected levels when they are locked.
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 any-
one — even the user who issued the lock — from routing to the destination.
In MD mode, a “P” appears next to the destination when it is protected.
In X-Y mode, a “P” appears next to selected levels when they are protected.
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.
[Forward] The panel software can introduce a “forward” button if an automatically generated
list has more entries than can fit on a page.
A ‘Forward’ displays and activates the next button page in an automatically gener-
ated sequence.
There is no explicit ‘Forward’ button type; configurers cannot create forward but-
tons explicitly.
Global
Navigate A global navigation button is very much like a navigation button to the operator.
However, during configuration, it selects a previously defined “global navigation”
template. The template itself may have structure that ordinary button pages have. It
can include any button type except additional global navigate buttons. See
Global
Navigation on page 37.
Hold In multi-destination mode, Hold retains destination selections after a take. In X-Y
mode, Hold retains breakaway levels after a take. (There are other effects. See
Selection Buttons on page 34.)
