| **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 **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 **Command 0xD811 - Start Send File to Device (Secured)**.
