Tally Menu
The Tally menu (Figure 2-24) allows you to test and observe the switcherÕs
tally outputs to determine whether your connections to external devices
are working. This menu also includes an
AUX TLY BACK
(Aux Bus Tally
Back)
ON/OFF
selection. When ON, this feature allows use of a GPI to tally
Aux Bus 1 whenever the effects send Þll crosspoint is tallied and Aux Bus
2 whenever the effects send source crosspoint is tallied. This provides tally
back for an external DPM without requiring a tally back input from the
DPM. To use this feature, it must be enabled in the Tally menu and assigned
as an event to a GPI input in the GPI Inputs menu.
The Tally menu displays a table listing the 16 physical inputs along with
the signal name for each input. If a physical input is currently being high-
tallied, that physical input will be highlighted in the table.
To test a tally output, select the desired input on the PGM bus and watch
the Tally menu display to see that the selected input highlights. To test all
of the tally outputs, set the
[TALLY TEST]
soft button to the
ON
position; this
cycles each output on for about 1/2 second. When finished testing, set the
[TALLY TEST]
button to
OFF
.
