Operation
Operating Concepts
• Select a destination category and initiate device selection for that category.
• During the process of device selection, add a suffix to the pending device name.
A category button can provide any or all of these functions.
A typical NV9603A configuration has a “keypad” with which you can enter category mnemonics
and device suffixes. (The keypad buttons are category buttons.) Consult your administrator to
learn what functions your panel’s keypad buttons perform. We presume that your panel’s
button legends provide a good indication.
Category buttons are affected by source mode and destination mode. Only source categories
are available in source mode; only destination categories are available in destination mode. Use
a ‘Source Mode’, ‘Destination Mode’ or ‘Src/Dst Mode’ button to select the mode of your choice.
These are basic steps to perform category device selection:
1 Press one category button to select a category and initiate device selection. The category
mnemonic appears in the ‘Preset’ field of the display as the beginning of a device name.
2 Press one or more suffix buttons to complete the selection, within that category. For
instance, for device VTR_12, press a “VTR” category button and then press a “1” button and a
“2” category button.
The names of devices in categories are composed of the category name followed by one or
more suffixes. NV9000-SE Utilities allows configurers to designate a separator character which is
inserted between the parts of the device name. (Device names are limited to 8 characters,
however.)
 You cannot perform a name set change using a ‘Nameset Toggle’ button while a category
selection is in progress.
Chop
When a “chop” function is supported by a router, the button is a toggle that enables and
disables “chop.” Chop is a rapid switching of the current destination device between one source
and another source.
The chop function is used to test system timing and would
not be used during normal
operation.
The use of the chop function varies according to the operating mode. See Chop on page 38.
Clear
The ‘Clear’ button reverts the panel to the most recent preset. (It does not cause any changes to
the routers, control system, or its signals.)
You may think of this as a “backspace” or “cancel” key. During category/suffix device selection, it
erases the suffixes you entered in reverse order.
Destination
The button selects a destination. The destination name appears in the ‘Destination’ display. The
destination is the target of an upcoming take, which will route a source to that destination.
A destination button represents two destinations. The destination selected when you press the
button is affected by whether your panel has a ‘Destination Shift’ button and its state: whether it
is selected or not.
