Device Registration

The following page describes the device registration process in an AEM Screens project.

Registering a Device

The device registration process is done on 2 separate machines:
  • The actual device to be registered, for example your Signage Display
  • The AEM server that is used to register your device
Once you download the latest Windows Player ( .exe ), from AEM 6.4 Player Downloads page, follow the steps on the player to complete the ad-hoc installation:
  1. Long-press on the top left corner to open the admin panel.
  2. Navigate to Configuration from the left action menu and enter the location address of the AEM instance in Server and click Save .
  3. Click on the Registration link from the left action menu and the steps below to complete the device registation process.
  1. On your device, start the AEM Screens Player. The registration UI is shown.
  2. In AEM, navigate to the Devices folder of your project.
    To get more information on creating a new project for Screens in the AEM dashboard, see Create and Manage Screens Project .
  3. Tap/click the Device Manager button in the action bar.
  4. Tap/click the Device Registration button on the top right.
  5. Select the required device (same as step 1) and tap/click Register Device .
  6. In AEM, wait for the device to send its registration code.
  7. In your device, check the Registration Code .
  8. If the Registration Code is the same on both machines, tap/click Validate button in AEM, as shown in the step (6).
  9. Set the desired name for the device, and click** Register**.
  10. Tap/click** Finish** to complete the registration process.
    The Register New allows you to register a new device.
    The Assign Display lets you directly add the device to a display.
    If you click Finish , you will need to assign the device to a display.
    To learn more about creating and managing a display for your Screens project, please refer to Creating and Managing Displays .

Assigning Device to a Display

If you have not assigned the device to a display, follow the steps below to assign your device to a display in your AEM Screens project:
  1. Select the device and click Assign Device from the action bar.
  2. Select the path of the display in Display/Device Config Path .
  3. Click Assign when you select the path.
  4. Click Finish once the device is assigned successfully, as shown in the figure below.
    Additionally, you can view the display dashboard on clicking Finish .

Limitations on Device Registration

System wide user password restrictions might cause failure in the device registration. The device registration uses a random generated password to create the device user.
If the password is restricted by the AuthorizableActionProvider configuration, creating the device user might fail.
The current generated random password is composed of 36 ASCII characters, ranging from 33 - 122 (includes almost all special characters).
