I just bought the Op. 192 and I haven't been able to program it. I only need for a pair of Color fusion fixtures from American Dj. As far as I understood from the manual those instructions are only for moving heads, right? Thanks for the help.

no not really those are general instructions. basically each fixture button controls a set of 16 dmx channels. so if your color fusions are say 6 channels each. And you have the first one addressed to 1 and the second one addressed to 7. then that means that if u have your fixture one button on (Green LED on) if you move faders 1-6 it will adjust the channels for your first light. now if u hit the channel bank button u will have access to the rest of your channels used on your second fixture.
however if you address the second adj fixture to 17 then u may as well just select between fixture one button and fixture 2 button. Hope this make sense. Let me know. Welcome to the forums.
Sincerely,

It will be much to ask if you could guide me step by step on how to program it?

Let me re-word that, I need help with addressing my fixtures, only one is responding. Help please. fix: 2 color fusion, 7 channel.

On your second fixture you need to have dipswitches 1 and 5 UP or on. That will give u access to the fixture from the 2nd fixture button. ok? Let me know if you still need help.
Sincerely,

Thanks for the response, I was not sure how Op. 192 worked. I used to use show designer 3 and I thought that I needed to patch each fixture. I am getting a hold of the op. 192 and I think it is going well so far. I will probably bug some other time if I get stuck on something else,
