I'll go about downloading a manual for the Mighy Scans, but I fail to see why there would be a need to use addresses specifically to "support" the DMX Operator, as it is merely a 192 channel DMX controller.
The DMX Operator DOES NOT support anything being synchronized. Never has, never will. It operates the chases based on sound active or timing. Timing is sketchy at best.
As far as the Scans doing 1&3 left/2&4 Right... well, it's entirely possible. First, if you're uisng individual addressing(or addressing in pairs), you can easily do this. Simply program 1 pair to do one thing and the other pair to do the other thing. Another option is if you had an X-invert on the Mightly Scans, you could invert X on 2 of them(say, 2&4), but then, realize that that's going to keep those fixtures reversed to 1&3 no matter what. Not saying that's necessarily a bad thing, it is an option to consider. Me, personally, I want control, so I wouldn't do that.
Sorry, I don't have time on the phone to help for the next 3 weeks and I don't have easy access to my DMX Operator, but I can get to my DMX Operator easier than I can have phone time.
(I'm in preparation for a show and it's very time consuming and highly detailed oriented)
After reading the manual, I see nothing to lead me to thing there is some special mode for working with the DMX Operator. This is a 6-channel DMX fixture, and you have 4 of them requiring 24 addresses if you want individual control.
If it was me, this is how I'd program them:
Scanner 1 would be assigned DMX starting address of 1.
Scanner 2 would be assigned to DMX Starting Address 9
Scanner 3 would go to DMX Addres 17
Scanner 4 would go to DMX Address 25
Yes, we are skipping addresses and leaving them purposely unused. Or at least not utilizing them for something else.
Now, when you hit Scanner Button 1, you have access to Scanner 1 via the faders. Hit the Shift button and those faders allow you to control Scanner 2.
Hitting Scanner Button 2 gives you access to scanners 2 & 4 via the same way you accessed the first 2 scanners.
If you hit Scanner buttons 1&2, you can directly control Mighty Scans 1&3 at the same time, then SHIFT and control Might Scans 2&4.
The bottom line is that what you want to do is entirely possible. You're just not thinking right yet.
DIP switch programming: using the DMX address DIP switch:
Mighty Scan 1: 1 on
Mighty Scan 2: 1,4 on
Mighty Scan 3: 1,6 on
Mighty Scan 4:1,4,6 on.
If you always use 1&3 as a pair and 2&4 as a pair, then give 1&3 the same address, and set 2&4 to their own addresses.
You can't do this all at once, you need to program 1&3 and 2&4 to do their own things on the same scene. So, if you're having 1&3 go left while 2&4 go right, you're going to have to program the lights to do just that. I say this assuming you're not using an X-invert setting, which I don't see as a supported option or feature on this item.
