# Install and configure the Flash Bridge

The Flash Bridge app must be installed on any computer running a centrally-managed app (Central Manager, Central Server, Central Client, centrally-managed Store Manager, centrally-managed POS, Central Loyalty Manager). The Flash Bridge app acts as a vault where packages are stored until they can be processed and synchronized between Central Client and Central Server. The Flash Bridge app is not required in single-store installations.

**To install the Flash Bridge app:**

1. Go to the location where you extracted the release package files.
2. Double-click **Setup.exe** to open the setup wizard.

**To configure the Flash Bridge app for Central Client and Central Server:**

   1. On the **Client Services** tab, select **Check this option to change this URL**.
   2. Enter the host name and port for the **RMH Store \[number] Input Gateway**.
   3. Click T**est address** to verify the address.
   4. 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.

**To check if the Flash Bridge app is connected:**

1. Open the system tray.
2. Double-click the **Flash Bridge** icon.

{% hint style="info" %}
If the Flash Bridge icon is not visible in the system tray, open **Settings**, click **Personalization** | **Taskbar**, and expand **Other system tray icons**. Beside **RMH.Central.FlashBridge.Application**, drag the slider to **On**. You will need to restart the computer for the icon to display in the system tray.
{% endhint %}

3. Check the connection status indicator in the bottom right corner of the **RMH Flash Bridge** window. If the indicator is green, the Flash Bridge is connected. If the indicator is red, the Flash Bridge is not connected and no packages are being processed and synchronized between Central Client and Central Server.

## 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/installation-flash-bridge.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.
