Hi! I am upgrading existing system with video-sync input. Existing are 1x PRO and 2x INTRO QM200 cards. Is enough to connect video-sync to one card and is signal then distributed through software to other cards OR is needed to connect the same sync signal to all cards (DB-15)? How about different sync for every QM card? P.S. How is with dmx? When enabled, all cards output the same signal or are different dmx frames routed thru Zones to different cards? Thank you. Aljaz.
