User’s Guide
When a take involving a machine control level is blocked on the control level, the display
displays the message “Control In Use.”
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.
This data routing option applies in both operating modes.
Semi-Automatic Data Routing
This data routing option applies only in X-Y 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.
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 NV9601 enters “salvo mode”
1
when you press a salvo button. Salvo mode is a temporary
mode, usually brief, where you are given an opportunity to select and consider the salvo you are
about to execute. The NV9601’s display gives you a list of all salvos, system and local. To execute
a salvo, select the salvo and press ‘Take’.
