Stage DMX lighting system haunted?
Hi. I'm having issues with my school's lighting system in our "theatre". I am new to the school here in Viet Nam and no one here has a clue how to use this lighting system. It is a 20 LED par can light system, 3 pin DMX throughout, a board that looks like a Chauvet Obey 40 but seems to be some kind of no-name DMX 512 desk. The lights look to have been daisy chained. In the past, they have been used as just a plain red wash or green wash or flashing mode. It was working ok but the stage looked like hell. I WANT to be able to control them individually. They were all initially set up with their dip switches set for 1 and 10 only.
I have tried setting them to separate channels (i.e. changing the dip switches to 1 then 1,5 etc.) but once I did that, they started randomly flashing. I tried switching them back to 1,10 but they are still doing their own thing. I tried setting them all to the proper address with 10 switched on too. Still no response. Now, I can't even get them back to going all red.
I'm fairly new to DMX systems. Can anyone offer suggestions as to what the heck I have done wrong?
I also have a couple of other questions.
Since I have 20 par cans but only 12 fixture buttons, can I assign 2 lights to one address?
Could the polarity switch on the back of the board do this?
Help, please, anybody.
