DMX, Pixlite4, adressing the second universe /ran out of ideas/ how to move on

Beginners

Hi guys,
My setup has 6 LED strips(each strip 50LEDs).
Here is an overview of my touchdesigner network:

When I send the pixel of the rectangeTOP from left to right, it moves as expected in universe0.
But when I plug the rectangleTOP in universe1 and start the test again, it starts at LED170 instead of LED151.

I know that a dmx universe has the capacity of 170rgb pixels max, so I think it has something to do with that. I only instanced 150 points per universe in the SOP section, so it should work out in my opinion. What do you think?

Another resource for the mistake could also be in the advatek assistant configuration, because in the advanced output settings, the “end channel” is greyed out and I cant change the parameters.

I add this information because my goal is to map 40 of those strips and sooner or later I have to change settings her.
I made a support ticket to advatek and they did not respond yet.
So I would be happy to recieve any kind of advice to this topic.

Kind regards,

Hi @Compilervisuals,

Because of the strips all on the same output, you need to fill the universes with the 170 leds before starting a new one.
It might be best to fetch all color values of all pixels (points) first, then “Sequence All Samples” using the Shuffle CHOP and finally “Split N Samples” with the N parameter of the Shuffle CHOP set to “510”…

cheers

you mean to set it up this way?

Strip 4 is still starting at LED171.
Do I need to use 170 points in the line sop? But this did not work either.

Hi @Compilervisuals

start with setting the Line SOP’s Number of Points parameter to the same number of LEDs - in your case 300. Now when converting this to a CHOP and shuffling it, you will get a channel with 900 samples. The next Shuffle with “Split N Samples” will split this into 2 universes that can then be send to the device.

Hope this works
cheers
