Introduction
Tally Interface
At the rear of the panel is a DB25 connector that provides 8 tally inputs and 4 tally outputs. (The
outputs are solid state relay outputs.) Both inputs and outputs are optically isolated.
During configuration, you can construct Boolean logic that switches the outputs on or off. The
terms of the logic expressions are states of the source and destination devices, etc., controlled
by the NV9000 control system.
During configuration, you can prescribe NV9606 behavior that depends on the tally inputs.
What you connect to the tally interface is, of course, up to you. Miranda provides a breakout
cable (WC0053) that can be used with the tally connector, as a purchase option.
The tally interface is also called a GPIO interface. On the rear of the panel, it is labelled a “GPI
interface.”
Modes of Operation
By itself, the NV9606 operates in a very limited X-Y mode.
As an NV9607 extension, the NV9606 can operate in any of the modes configured for the
NV9607.
• Limited X-Y Mode .
• Single-Destination Mode .
• Single-Destination Mode with Breakaway .
• Multi-Destination Mode .
The panel’s set of button functions varies with the mode.
The modes (or behavioral models) are determined at configuration for both the NV9606 and the
NV9607. The operator cannot switch between different modes.
Limited X-Y Mode
In limited X-Y mode, takes occur from a single source to a single destination (selectable).
Pressing a source button completes a take unless the corresponding NV9607 has a ‘Source
Preview’ button and it is active (high-tally).
Breakaway is possible in this mode if the panel has level buttons. Level buttons selected the
levels on which the take is to occur. Takes occur on all levels when either no levels are selected
or when all levels are selected.
Single-Destination Mode
In single destination mode, the panel’s destination is configured as the default destination and
there are no destination buttons.
Pressing a source button completes a take unless the corresponding NV9607 has a ‘Source
Preview’ button and it is active (high-tally).
Takes are all-level.
1. The NV9606V (virtual panel) has automatically generated button legends. For instance, a source but-
ton’s legend is the source name. Depending on the operating mode, the source button might have up
to 3 lines of text: a source from page 1, a source from page 2, and a destination.
