The Interface
The tally interface includes 8 optically isolated inputs and 4 solid-state relay outputs (also optically
isolated). Tally devices you connect to inputs can trigger events
—
through the NV9607
—
in the
router control system. The router control system can trigger events that
—
through the relays in the
NV9607
—
switch your tally devices.
The DB25 connector, labeled “GPI Interface” at the rear of the NV9607 presents the tally signals.
There are 8 input signals and 4 pairs of output signals.
Figure 6-1. GPI Interface
Input
The tally inputs expect contact closure to ground, through the ground pins on the connector, to trig-
ger a GPI input event.
Figure 6-2. GPI Input
When the input transitions off or transitions on, the NV9607 notifies the router control system,
which carries out the task defined for the input (if a task has been configured).
