During configuration, you can prescribe NV9649 behavior that depends on the tally inputs.
What you connect to the tally interface is, of course, up to you. Grass Valley provides a
breakout cable (WC0053) for the tally connector as a purchase option.
The NV9000-SE Utilities on-line help documentation calls the tally interface a GPIO
interface. On the rear of the panel, it is labeled a "GPI interface. "
See chapter 6, GPIO, on page 129, for complete detail.

Modes of Operation

The NV9649 has 3 operating modes (or behavioral models). The panel's 28 buttons and 4
displays are used in very different ways in the 3 modes.

'Panel Server' Mode

When the panel is in "server" mode, it operates in conjunction with a number of NV9648s.
The NV9649 is the "server" and the NV9648s are the "clients. " The NV9649 and the NV9648s
combine to form, in essence, a larger panel — actually a cluster of many small control units.
The NV9649, being the server, can change which sources and destinations the NV9648s can
use.
Each NV9648 has 3 identical sections and, in client mode, each section functions as a
complete and separate control unit, unrelated to any other NV9648 section. Each displays
shows a destination chosen by the operator of the NV9649. (The NV9649 can also assign
sources to the source buttons of individual NV9648 control units.)
The display in each of the clients' control units shows the control unit's current source when
the NV9649 is in source mode and show the control unit's destination when NV9649 is in
destination mode. See
Special
Modes, on page 10.
