NV9575-VF
The NV575-VF is a tally interface:
This 1RU device (also called a tally expander) is not a router control panel although you can con-
figure it in SE. It has no controls on its front panel. What it does have are 64 relay outputs and 32
optically isolated inputs, typically used for tally functions.
The NV9575-VF has 6 DB25 connectors on its rear panel — J1 through J6. J1, J2, J4, and J5 pro-
vide connections for the 64 relay outputs, 16 per connector, with 8 pins common. J3 and J6 provide
connections for the 32 inputs, also 16 per connector with 8 pins common.
Each relay can be configured to switch on a number of conditions:
• One or more routes occurring on specific levels.
• Conditions involving output ports (destination, level).
• A transition on one or more of the NV9575-VF inputs.
Each input (also called a GPI) can be configured to trigger a salvo on a transition from off to on and
to trigger another salvo on a transition from on to off.
See NV9575-VF on page 329 for information regarding the ‘NV9575-VF’ configuration page.
