Settings > GPI set up
The NVP-20 can be controlled externally via a GPI (General Purpose Interface)
switch.
This could be a push button, foot switch, switcher or any relay or circuit that is
able to provide a simple contact closure. Contact closure between the Outer
and Inner contacts on the jack plug will trigger a user selected event.
The GPI interface is a 3.5mm Jack Socket which is situated on the rear panel
of the NVP-20.
Please Note:
Power is supplied by the NVP-20 and is less than 5V DC.
SAFETY FIRST
The cabling required needs to be designed specifically to connect the NVP-20
to the chosen GPI source as they are not all the same. The cabling required
can be made by yourself or a competent technician. Please speak with your
Dealer or local Datavideo office to get further help and advice.
The NVP-20 supports two GPI trigger modes selectable via the web interface.
Level Trigger
Contact closure between the Outer and Inner contacts on the jack plug will
trigger the PLAY button to be pressed once, if the contacts are released
during clip playback the PAUSE button will be pressed once.
Pulse Trigger
Momentary contact closure.
Contact closure between the Outer and Inner
contacts on the jack plug will trigger the PLAY button to be pressed once, if
GPI is triggered during clip playback the PAUSE/RESUME button will be
pressed.
