| **Properties are stored in flash memory, which inherently has a limited number of read- write cycles before it begins to wear. For this reason, MagTek recommends setting properties as few times as possible over the lifecycle of the device.** |

The host uses this command to set device configuration / settings securely. Properties that require security should specify that they do in their documentation. This command can also be used for properties that do not require security.

The details, request data and response data of this command are identical to what is documented in [<mark style="color:red;">**Command 0xD111 - Set Property (Unsecured)**</mark>](https://developer.magtek.com/api-and-command-reference/dynafamily-programmers-manual/commands/0xd1nn-settings-and-information/0xd111-set-property-unsecured#request-data-for-command-0xd111-set-property-unsecured)**,** however, the command must be structured and sent according to what is documented in sequence of events 1-5 of [<mark style="color:red;">**Command 0xD811 - Start Send File to Device (Secured)**</mark>](https://developer.magtek.com/api-and-command-reference/dynafamily-programmers-manual/commands/0xd8nn-file-operations/0xd811-start-send-file-to-device-secured#response-data-for-command-0xd811-start-send-file-to-device-secured).

# 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 by asking a question.

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

```
GET https://developer.magtek.com/api-and-command-reference/dynafamily-programmers-manual/commands/0xd1nn-settings-and-information/0xd112-set-property-secured.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.
