Operation
Salvo Mode
If a control port for the source or destination is “in use,” a take involving a machine control level
occurs on all levels except the machine control level. Nevertheless, you are given the opportu-
nity to complete the take on the machine control level by pressing the ‘Take’ button a second
time.
If neither of the control ports for the source or destination are in use, the take occurs naturally
without any further action required. Note that the ports will become “in use” after the take you
are performing.
Follow these steps to take the data level as a breakaway:
1 Select a destination.
2 Select a source.
3 Examine the display and the take button.
4 If the display shows “Control in Use” and the Take button is still high-tally, press the ‘Take’
button again to complete the take.
You can cancel the control-level take by pressing a button other than ‘Take’.
Chop
The chop function is a diagnostic function for routers that support chop. It allows you to switch
rapidly between two sources at a particular destination. The chop interval is defined in the
NV9000 configuration. The default chop interval is 6 fields.
Follow these steps to use chop:
1 Select a destination. The ‘Destination’ field of the display shows the destination you chose.
2 Select a source. This is the first source.
3 Press the chop button.
4 Select another source. This is the second source. The chop is immediately activated on the
routers (of the default destination) that support chop.
To terminate the chop, (1) press the chop button again to turn it off, (2) select the destination
you had chosen for the chop, then (3) select any source.
Salvo Mode
The NV9654 enters a minor “salvo mode”
1
when you press a salvo button. Salvo mode is a
temporary mode, usually brief, where you are given an opportunity to reconsider the salvo you
are about to execute. The NV9654’s display tells you the name of the salvo and instructs you to
press the take button to execute the salvo. If you wish to cancel the salvo before it executes,
press the salvo button again.
After you press take or cancel the salvo, the panel returns to its previous mode.
See Salvo on page 68.
Menu Mode
The NV9654 enters menu mode when it has a menu button and you press it.
1. Other panels, such as the NV9601, have a more extensive “salvo mode.”
