Operation
Operating Concepts
Data Routing
There are 3 data routing options that affect sources and destinations that have a machine
control level (i.e., a data level). These options govern what happens when a source or destina-
tion device is to be used.
Automatic Data Routing
A take involving a machine control level occurs automatically, without intervention, regardless
of who is using a device.
This option applies in all operating modes.
Manual Data Routing
A take involving a machine control level occurs on all levels except the machine control level.
You must route the machine control level as a breakaway.
When a take involving a machine control level occurs, the status display shows the name of the
machine control level and the destination display shows “In Use.” That is a signal that you need
to take the machine control level as a breakaway.
This option applies only in limited X-Y mode.
Semi-Automatic Data Routing
A take involving a source or a destination having a machine control level might not occur imme-
diately if the source or destination device is in use.
This option applies in all operating modes.
If neither device is “in use” the take occurs immediately. Otherwise, you need to press the source
button again to complete the take.
If the source device is in use, the ‘Status’ display shows “Src Used” and the destination dis-
play shows “Retry?”
If the source device is in use, the ‘Status’ display shows “DestUsed” and the destination dis-
play shows “Retry?”
If the source device is in use, the ‘Status’ display shows “BothUsed” and the destination dis-
play shows “Retry?”
If you do not press the (same) source button again, the take is canceled. (It will time out.)
Follow these steps:
1 Press a destination button.
2 Press a source button.
3 Examine the display.
4 If the destination display shows “Retry,” press the source button again to complete the take.
The take will time out if you do not press the source button.
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.
