so i have another thread about chasing lights and how to do them. this is what i have built so far. 4x8 Hollywood flat with a design in the middle with light surrounding it. i have the light going left to right in a 123 order with the wiring. what i was planing on doing was either putting all the one, two, three on 3 stage pin plugs then creating and effect on the board to make them chase. (we a innovator). but what i dont like about that is i would need to find 3 free or soon to be free ports and run extenders to them. (we dont have extenders). so i found a dimmer pack online for like $60 and thought it might be easier to run it to the dimmer pack. but i never used one before. correct me if im wrong but they plug iinto a dmx port and get programed into the board. the way our board is set up is: Port A is for conventional lighting, Port B is too but i dont think there is anything on it because there is no DMX cable coming from the back of the board to the wall on port b, and Port C for our movers. we are not using the movers for the show and the dimmer pack would be right next to Port C where the Movers are plugged into. if i unplug the mover and plug the dimmer pack in would it be hard to program the pack and can i just load the boards old config when i plug the movers back in after the show. one last thing is that if i cant use Port C we have a box off stage with Port A,B,C, and hhr. would it be better if i plug in on Port B and run a cord from the board to Port B in the booth. OH and thanks you for the help in the lights chasing thread.
