# UDP Messenger

The UDP Messenger, formerly the Stagehand Messenger, allows communication to outside control systems via a simple UDP text string. This feature was introduced to communicate with a proprietary AV controller in a permanent installation.

Set your Target Address to the [IP Address](https://docs.creativeconners.com/docs/spikemark/ip-address-and-network-connection) and the Port of the device that is listening for UDP messages in the Stagehand Properties Panel

In the Cue Workspace, add a “movement” by dragging and dropping the Messenger into a Cue and add your UDP String into the message to send box and Click Update.

In this example we are executing a manual entry to move the Submaster Fader 1 on our Lighting Console to 75%

The UDP Messenger sends out whatever text string is in the movement window when the cue is executed. In the above example, Spikemark is triggering a submaster change, though the text string can be anything you like. The important part is that the device listening for it understands it.
