Compared with our DMX 500x250mm 12x6 LEDs DMX panel,they wanna more smaller pixel pitch: 
Panel size 400x200mm & 20x10=200LEDs, pixel pitch at 20mm.It will be more bright.

For this panel, each one has a DMX IC chip, 3 DMX channels. with standard DMX512 signal.You can 

use any standard DMX controller or console to control it.

But pls notice, for this panel, you need set DMX address for each panel first via a DMX address writer. 

of course this opereation very easy. 

For more questions or any new idea, pls kindly let us know.
