GPIO Summary
The NV9680 has 4 relays that can switch on or off your external devices, based on (1)
NV9680 input transitions and (2) events configured in the GV - Orbit or GV Convergent. Its 8
inputs can be switched on or off by your external devices. When an input transitions on or
off, the NV9680 can respond with one of 4 actions, such as executing a salvo. It is GV - Orbit
that actually executes the salvo. See GPIO Configurator Tasks in the GV Orbit Control User
Guide
or
GV Convergent User’s Manual
. See Related Documentation , on page 2.
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
NV9680 — in GV - Orbit. The router control system can trigger events that — through the
relays in the NV9680 — switch your tally devices.
The DB25 connector, labeled “GPI Interface” at the rear of the NV9680 presents the tally
signals. There are 8 input signals and 4 pairs of output signals.
