I deleted them! ) 1: in my version [arnettodmx.ino](https://drive.google.com/file/d/1lax6UhxuM3iJGGEudI6olhnZNc2TO1VL/view?usp=sharing)(link to the modified file) I disabled all lines for LEDs, 2 : I added the selection of 16 universes with 4 dipswitches (see page [Address)](https://phebusco-led.blogspot.com/p/blog-page_7.html) connect to pins A0 to A3. If you keep the original ino file, the choice of the universe does this to the programming, modify the line byte UniverseID = {0}; In case of special reason you can change the number of Dmx channels as well as the position of the 1st channel const int number_of_channels = 512; *//512 for 512 channels* const int start_address = 0; * 0 if you want to read from channel 1* [![](https://1.bp.blogspot.com/-c7kBwbuRlp8/YJfG0KWCgBI/AAAAAAAARmc/9fuoTl220OY1-PCRcZ3YHvrieSJQiwFXwCLcBGAsYHQ/w400-h333/uno%252Bw5100.jpg)](https://1.bp.blogspot.com/-c7kBwbuRlp8/YJfG0KWCgBI/AAAAAAAARmc/9fuoTl220OY1-PCRcZ3YHvrieSJQiwFXwCLcBGAsYHQ/s1280/uno%252Bw5100.jpg) **DOCUMENTS** Code ArtGateOne-DMX[![](https://oldmaker.wiznet.io/wp-content/themes/onepress/assets/images/icon-link.png)](https://github.com/ArtGateOne/ArtGateOne-DMX) Artnet_to_DMX[![](https://oldmaker.wiznet.io/wp-content/themes/onepress/assets/images/icon-link.png)](https://github.com/scrime-u-bordeaux/Artnet_to_DMX) --- Source: https://maker.wiznet.io/WIZnet/projects/dmx-by-ethernet-with-wiznet-w5100/
