This page / section pertains to **BrightAuthor Classic**, our legacy app. **BrightSign Author **is our latest app for managing content and players.

Development of BrightAuthor Classic has largely ceased and the app will eventually be deprecated and replaced with BrightSign Author.
:::

With BrightAuthor Classic, one or more players can easily be rebooted if they are on the same local network. This can be done by adding an **Event** **Handler** that responds to a UDP message in the presentation(s) scheduled on the player. This will allow the BrightSign iOS app or any app capable of sending UDP messages to reboot the player with the appropriate message string. This method can be adapted for other trigger mechanisms like **Serial** **Input** and **GPIO** **Input**, but the advantage of UDP is that it is a network-based communication that does not require additional wiring or cables.

# Reboot Using an Event Handler

::::WorkflowBlock
:::WorkflowBlockItem
Open your presentation and select the **Edit** tab.
:::

:::WorkflowBlockItem
Select **Add Zone** as shown:

:::

:::WorkflowBlockItem
Add an **Images** zone with a suitable name. It will contain the **Event** **Handler** that will listen for the reboot requests.
:::

:::WorkflowBlockItem
Return to the **Playlist** view and select the zone you just added by opening the drop down or selecting the thumbnail.
:::

:::WorkflowBlockItem
Select **Interactive** to make the playlist interactive and the **other** tab in the Media Library.
:::

:::WorkflowBlockItem
Drag the **Event** **Handler** into the playlist storyboard and select the **events** tab in the Media Library.
:::

:::WorkflowBlockItem
Scroll down to find the **UDP Input** event, then drag and drop it onto the **Event** **Handler** that you just added. The **UDP Input Event** settings will now appear, as shown in Image 2.

- Enter the message that you want to use to trigger the reboot in **Specify UDP input**. This must be unique so it won't be triggered by any random UDP traffic on your network, otherwise your player will randomly reboot. For this example, use the message Reboot\_Me**.**
- The **Label** will be used by the player to identify the command, and by other apps that query the player for available events.
- If you want the reboot to appear as a button in the BrightSign iOS App, tick the box.
:::

:::WorkflowBlockItem
Select the **Advanced** tab and select **(+) Add Command,** which adds a command in the list.

- Change the **Commands** drop down to **Other**
- Change the **Command** **Parameters** drop down to **Reboot**.
- Select **Ok**.
:::

:::WorkflowBlockItem
**Save**, **Upload** (if necessary), and **Publish** your presentation. When you send the UDP message Reboot\_Me to the player, it will now reboot. If you have multiple players on the same network subnet and they are all listening on the same UDP port, you can send a UDP message to the subnet's broadcast address (i.e., 192.168.1.255 for everything on 192.168.1.x) and all the players that are listening for that command will respond.

Since this command lives in the presentation, if you want the same command to apply to other presentations, you will need to perform the same steps to add the **Event Handler** and **UDP Input** **Event** to those presentations as well.
