13. Operating Panels
Performing Level Selection
These examples show the difference between two orderings of level buttons. Figure 13-4 shows
level buttons in the order AV, AES, TC, SD:
Figure 13-4. Spatial Ordering AV, AES, TC, SD
Level AV is on the left and has the lowest button number. All levels are selected. Therefore, sources
and destinations that include level AV are enabled and other sources and destinations are disabled.
Figure 13-5 shows level buttons in the reverse order (SD, TC, AES, AV):
Figure 13-5. Spatial Ordering SD, TC, AES, AV
Level SD is now on the left and has the lowest button number. Again, all levels are selected.
Sources and destinations that include level SD are now enabled and other sources and destinations
are disabled.
Thus, with one level button ordering, AV sources are enabled. With the other, SD sources are
enabled.
If a panel’s level buttons are scattered across the panel, one should remember the ordering method:
(1) buttons in any row have higher precedence than buttons in lower rows and (2) within a row, but-
tons to the left have higher precedence than any to the right.
Temporal Ordering
Rule 2: when not all levels are selected, the sources and destinations that are enabled are those that
include the level that you select last. If no levels are selected, no sources and destinations are
enabled.
Figure 13-6 shows level buttons again in the order AV, A12, TC, SD, but this time with level AV
unselected:
Figure 13-6. Temporal Ordering AES, TC, SD
Although it is not visually apparent, when the A12 button is pressed last, the sources and destina-
tions that include A12 are enabled.
Figure 13-7 shows the same selected level buttons, but this time level SD was pressed last:
Figure 13-7. Temporal Ordering AES, TC, SD
The same level buttons were pressed here as in Figure 13-6, but in different order with a very dif-
ferent result. Sources and destinations having level SD are enabled.
