# Set DMX in Layer Layouts

It is also possible to set a value of a single channel with **Set DMX** layer node.

In our case, we overwrite Channel 2 in Universe 1 with the Value 220. This value will be sent, along with other DMX Channel values to the final endpoints, or DMX nodes.

It is also possible to set multiple channel values with a single *Set Data* node. You can do this by clicking on the **Add channel** button in the *Node properties* of the selected *Set Data* node.

Similarly, to remove a channel from the node, click on the **Remove channel** button.

**Good to know**: there is a Stock Layer Template that does that already. It's called [Send DMX](/layers-and-layouts/stock-layer-templates/control-layer-templates/send-dmx.md).
