* If you plan to route the cable out the back of the device, route the cable through the cable management clip to change its direction. Even if you are not routing out the back, you may use the cable clip for strain relief, to help stabilize the mechanical connection when cardholders or operators move the device or the cable.
* Route the cable in the desired direction (e.g., out the back, left, right, or down into the countertop).
* Connect the other end of the USB cable to the host’s USB port.
* As soon as the device starts receiving power through USB, it automatically powers on.
* Launch the DynaFlex Utility and select DynaFlex device in the Device Type list, then press the connect button.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developer.magtek.com/hardware/card-readers/mms-dyna-devices/dynaflex-ii-go/documentation/user-manuals/google-wallet-smart-tap-integration/how-to-connect-to-devices-using-dynaflex-utility.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
