# Modify the Central Client settings
{% hint style="info" %}
Refer to [**Use the Consistency Checker**](/installation/install-central-manager-multi-store/manage-services/consistency-checker.md) for information about how to use the options on the Consistency Checker tab.
{% endhint %}
1. Double-click the **Central Client** icon on the desktop.
2. Click **Settings**.
3. On the **Database Connection** tab, modify the **Store SQL Server Instance**, **Database Name**, **User ID**, and **Password** as required.
{% hint style="info" %}
If you change the database, select **Check this option to recreate config file**. Central Client reads the config file for store database information. The config file is usually found under **C:\ProgramData\RetailHero\RMH Central Flash Client**.
{% endhint %}
4. On the **Client Services** tab, modify the **RMH Store \[number] Input Gateway** host name and port as required. The **RMH Store \[number] Input Gateway URL** is automatically set after a successful connection to Central Server. To change it:
1. Select **Check this option to change this URL** and enter the host name and port for the computer where Central Client is installed.
2. Click **Test Address** to verify the address.
3. Click **Save**. The host name and port are saved to the Store Manager database. The Flash Bridge app will use this host name and port to send data packages/jobs to the Central Client to synchronize to Central Server and Central Manager.
{% hint style="info" %}
Enter a unique port number for each service.
{% endhint %}
5. On the **Server Connection** tab:
* Check the **RMH Central Input Gateway** host name and port.
* (Optional) Enter the **Store Key** that you are using to authenticate the store to Central Manager.
{% hint style="warning" %}
If you choose to use Store Key for store authentication, you must first add the Store Key in Central Manager and then restart the Central Server services. Refer to [Add the store to Central Manager](/installation/install-central-manager-multi-store/installation-cm-configure-store.md) for more information. After you have confirmed that the Central Server services are running, you must add the Store Key in Central Client (this procedure) and restart Central Client services.
{% endhint %}
6. On the **Setting Mode** tab, modify the following as required:
* **Log init sync result:** Select to log the results of the initial synchronization between the store's database and the Central database.
* **Delete the logs after:** Records are only kept in the log for the number of days indicated. After that, records are deleted from the log. The default number of days to keep records in the log is 7 days. The minimum number of days is 7 and the maximum is 90.
* **Retry attempts before declaring failure:** The maximum number of attempts that will be made to process a job before the system identifies a job as failed.
* **Retry interval between each attempt:** The time between retry attempts.
* **Delete failed jobs after failure:** Failed jobs are only kept for the number of days indicated. After that, failed jobs are deleted.
7. Click **Save**.

## 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.rmhpos.com/installation/install-central-manager-multi-store/manage-services/modify-settings/central-client-settings.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.
