In this article you will learn to create, manage or duplicate devices. In addition, you will learn how to assign a device to a mini-PC. You will also learn how to assign a layout to a device and view it using the preview feature in your browser.
The device overview shows you all active devices assigned to the project.
Each device is represented here by its own tile and represents exactly one Mini-PC. This contains basic information about the system state of the respective Mini-PC. The system state is transmitted to the management system, provided that the so-called RCT software has been installed on the Mini-PC and the MAC address of the Mini-PC has been linked to the device.
Notice:
The RCT software is automatically pre-installed on our devices. If you use your own Mini-PC, contact our support via e-mail.
This basic information includes a picture of the current screen display, Internet connection quality, system load information, and the time of the last contact with the management system.
Notice:
You can enlarge the preview image for a device by left-clicking on it.
By clicking on DETAILS you can change the properties, social media configuration or layout of a device.
Press on the tile to jump directly to the social media configuration or layout of a device. In addition, you can also delete the device here.
Notice:
Deleting a device will not delete an assigned configuration or layout.
By clicking on PREVIEW you can jump to the display of the respective device and view it in your browser with the configured layout and the set social media configuration.
More details can be found in the KB article Preview layout.
An overview of all devices (including deactivated devices) can be found in the menu under the menu item: devices.
# Create devices
To create a new device switch to the overview of all devices (menu item: devices).
You can add a new device by clicking on the + button in the bottom right corner. Then a new dialog will open:
For each device you have to assign a name (e.g. device 1), a location (e.g. Input South), the manufacturer and the model of the used Mini-PC (e.g. Minix Neo Z83-4).
You must also set the time period during which the device is to be active. Set the width and height of the device to match the screen resolution (in pixels) of the display intended for the mini-PC. You will also need to select a layout and social media configuration.
Notice:
When you create a new device, a blank social media configuration and a new layout are automatically created.
You can adjust the following two properties according to your circumstances. Make sure you select them wisely.
Notice:
- Update rate:
- Time interval (in milliseconds) after which a device queries our server system for new social media content.
- Queue size:
- Defines how much social media content to hold for display on this device.
- The total queue size for social media content is the sum of highlight and regular content. It represents the total number of different social media content matching the selected social media configuration,
The button STORE adds the device to your project. The button will only become active once all the required information has been entered.
