Configuring Inputs; Gpio Summary - GRASS VALLEY NV9649 User Manual

 Relay output expressions can be as rich (or complex) as you require.

Configuring Inputs

Clicking an input button (one of 8) displays the GPI input dialog:
An event is signalled when a transition occurs on the input from on to off or from off to on.
You can configure the NV9649 to recognize either occurrence on any of the 8 inputs, and
specify one of 4 behaviors for each event or both:
1 Execute a salvo.
If you choose this behavior, select a salvo ID in the salvo drop-down list.
Note: Although it is not evident in the GPIO input dialog (or anywhere else), a 'Previous
Source' command in a salvo chooses the most recent source that is different from the
current source (for a designated destination).
2 Route the "previous source" (that was switched by any control panel) to a destination,
even if it is the same as the current source.
If you choose this behavior, select a destination in the destination drop-down list.
3 Route the "previous source" switched by this panel to a destination, even if it is the
same as the current source.
If you choose this behavior, select a destination in the destination drop-down list.
4 Route a source to a destination.
If you choose this behavior, select a source and a destination in the two drop-down
lists.

GPIO Summary

The NV9649 has 4 relays that can switch on or off your external devices, based on (1)
NV9649 input transitions and (2) events in the router control system.
Its 8 inputs can be switched on or off by your external devices. When an input transitions on
or off, the NV9649 can respond with one of 4 actions, such as executing a salvo. (It is the
system that actually executes the salvo.)
