# Configuring parameters for single device
Configure device parameters with role-based access control in VHQ, managing basic and advanced parameter templates through the Device Profile with specific user rights and privileges.
{% hint style="info" %}
**Use this when** you need to view or edit application parameters for one specific device.
{% endhint %}
## Configure application parameters for a single device
{% stepper %}
{% step %}
### Find the device
Go to the *Device Search* screen and search for the device.
{% endstep %}
{% step %}
### Open the device profile
Click the serial number in the *Serial#* column to view the *Device Profile*.
{% endstep %}
{% step %}
### Open the Parameter tab
On *Device Profile*, click **Device Details** > **Parameter**.
{% endstep %}
{% endstepper %}
This screen shows all applications assigned to the device. You can configure an application's parameters by editing values and assigning parameter templates. Based on the form view file, basic and advanced parameter editing is controlled by access levels: *Advanced*, *Basic*, *View*, and *None*. Access control applies at both the container and parameter level, with container-level access always taking precedence.
## Access and rights reference

VHQ provides separate rights and privileges for editing parameters, distinct from device rights.
{% hint style="info" %}
Currently, a user with basic or advanced parameter rights can edit the parameters of a single device from the device profile.
{% endhint %}
## Import and activation rights
Alongside basic and advanced parameter rights, VHQ adds:
* **Import parameter right**: Lets a user import devices and hierarchy in VHQ. VHQ checks device rights during import, based on the operations specified in the XML.
* **Activation parameter right**: Lets a user activate parameters. The user must also have the device modify right — with only the device right, they can update parameters in the UI but not send them to the device. Sending or activating parameters requires the activation parameter right.
## Global operation rights
VHQ restricts global operations — those involving more than one device — in the *Device Search* screen based on a separate global rights layer, on top of existing per-operation rights.
Keywords
Also called: single device parameters, device profile parameters. Search terms: basic parameters, advanced parameters, import right, activation right, global rights.

## 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://docs.verifone.com/support-us/verifone-hq/vhq-parameter-management/configuring-parameter-templates/configuring-parameters-for-single-device.md?ask=&goal=
```
`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.
