#Gpi and Par
5 messages in this thread
Im beginning to do animations that are long enough to require frame accurate
laying off to tape of par segments. I recall that some forum folk were using
the GPI trigger to control the par. Any details on how this is accomplished
would be appreciated.

Edward- It's pretty staight forward if you have an editor with GPI trigger.
The connection to the Par is the RCA jack on the multipin breakout cable. It is
simply a contact closure (to my knowledge). The RCA jack on the Par is
connected to one of the triggers on our Sony editor. To execute it, we simply
tell the editor what timecode to fire the trigger, set the animation to the
first frame, arm the trigger in the Par S/W, and make the edit. Hope that
helps. -Mark
Thanks for the information
Im having a cable made so I can trigger it from a Vlan controller. I needed
to know that it triggers on a closure.

I believe it triggers on a +5vdc pulse. This usually what the GPI interface
generates on send. At least this is what I see on the scope. The other thing
you might need to calibrate is the GPI timing delay in the PAR. This is setup
in the submenu and is very accurate. We have ours set for 5.00 seconds which
is the delay for the preroll. Our controller does a 5 second preroll after
sending the GPI pulse. In other installations you may need no delay.
Thanks Don
