Operation
Operating Concepts
Automatic Data Routing
A take involving a machine control level occurs naturally on all selected levels, including the
machine control level, regardless of whether an affected machine control port is in use. The
system breaks any existing control connections involved with the source and destination and
makes a new control connection for the source and destination.
This data routing option applies in both operating modes.
Manual Data Routing
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. You must break either the source’s control
connection, the destination’s control connection, or both of those existing connections before
you can take the source to the destination on the machine control level. To break a connection,
route a device (as a source) to itself (as a destination) on the machine control level. When the
connection is broken, the status column of the display reads “FREE” for the machine control
level (in X-Y mode). If your panel is in multi-destination mode, you might switch to X-Y mode
momentarily to see this.
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
