1. Introduction
The Ubiquiti UC-CAST-US Display Cast is a compact device designed to transform any HDMI-compatible television display into a managed digital signage unit. It allows for the presentation of multimedia playlists created within the UniFi Connect ecosystem, offering a streamlined solution for digital content delivery.
2. Setup
Follow these steps to set up your Ubiquiti UC-CAST-US Display Cast:
- Connect to Display: Plug the UC-CAST-US device into an available HDMI port on your television or display.
- Power the Device: The device can be powered in two ways:
- Power over Ethernet (PoE): Connect an Ethernet cable from a PoE-enabled switch or injector to the "PoE IN" RJ45 port on the UC-CAST-US.
- USB-C Adapter: Alternatively, connect a 5V DC, 1A USB-C power adapter (not always included, check package contents) to the USB-C port.
- Network Connection: Ensure the device has network connectivity. If using PoE, network is provided via the Ethernet cable. If using USB-C power, ensure the device is connected to a Wi-Fi network (configuration via UniFi Connect).
- UniFi Connect Integration: Access your UniFi Connect application to discover and manage the newly connected Display Cast device. Follow the on-screen instructions within UniFi Connect to complete the setup and assign content playlists.
