# Stagehand Pro 4: Showstopper Emergency Stop Input

![](https://3040525219-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MhFI6SSKpm8M7EkrYqp%2Fuploads%2Fgit-blob-4026ad6cd94708523565c9243554e3f09c9b2720%2Fe-stop%20input.png?alt=media)

The Stagehand requires a 24VDC Emergency Stop signal from a Showstopper in order to allow power to flow to the motor and brakes.

Internally, the Stagehand Pro has a redundant, self-monitoring circuit to ensure that power will be removed from the motor and brakes instantly if the 24VDC Emergency Stop signal is interrupted.

Before you can move any motor, you must connect the Stagehand to a [Showstopper](/docs/showstopper/showstopper-base.md) with a 5-pin XLR cable. The 5-pin XLR cable is not a DMX signal, but rather it was chosen as a convenient cable that is prevalent in many venues so you should always be able to find a spare cable when needed.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.creativeconners.com/docs/stagehand/stagehand-pro-ac/stagehand-pro-4-making-the-connections/stagehand-pro-4-showstopper-emergency-stop-input.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
