Reply to "Mixing Moving Fixtures with LED PARS"

Scott,

Please clarify your situation. What do you mean by "in line with the 4 moving heads?" They should be "in line" in the sense that you will want to run a DMX line from your controller to your first fixture, and then run a line from that fixture to the next and so on until all 8 of the fixtures are connected in a line of DMX cables.

But iff by "in line" you mean that you are running both a moving fixture and an LED Par can on the same DMX address, that is something you should not do.

You are obviously running the moving heads in 6 Channel mode. Even if the Par Cans happen to have a 6 channel mode, it is highly unlikely that the channels will line up correctly. For example, its unlikely that the channel for dimming happens to be the same channel for both fixtures. In short the signal that you want to send to the moving heads will be entirely different from the signal that you want to send to the LED Pars. If they are on the same address, one of them is going to get the wrong message.

Definitely run the LED Pars on different DMX addresses from the DMX addresses being used by the moving fixtures. If you want to be able to have have each LED Par do its own thing, then set each LED Par to a different DMX address and have those addresses outside the range of addresses being used by the moving heads (65 - 118).

Make sure that you know the number of channels each LED Par is using. Many LED pars have options with respect to the number of channels - the more channels used the more control you will have over the pars. And make sure that the DMX addresses don't overlap. For example, you are running your moving fixtures in 6 channel mode - so the DMX addresses are 6 numbers apart. The DMX address for your first par can could be 119. Unless you set all your LED Pars to 119 (and have them all do the same thing), you must set the DMX address for the next LED Par far enough above 119 so that there is no overlap. If you are going to run your LED Pars in 4 Channel mode, you would need to set the DMX address for the next LED Par at an address of 123 or higher. If you are going to run the cans in 7 channel mode, setting the DMX address at 123 wouldn't work because the signals would overlap.

Hope this helps.
