To start receiving Mo-Sys information insert a **MoSys Receiver** device.

On the right side, under the *Stream*, configurable properties for specific devices will be shown. After you configure them, check **Listen** checkbox inside the device node.

{% hint style="warning" %}
Please note, Mo-Sys doesn't allow using 127.0.0.1 (localhost).
{% endhint %}

### Read MoSys in Layer Layouts

To use the information read by **MoSys Receiver** node in LightAct, you need to create a **Read MoSys** node in the layouts.

Choose **MoSys** **Receiver** device in a **Device** dropdown menu, or connect **Device reference** node to this input, and you are ready to go.
