描述
The Novastar TB2-4G is an asynchronous multimedia player designed for full-colour LED displays. Unlike a synchronous sending card that needs a computer running next to the screen, the TB2 stores and plays your content on its own — it can be updated over the network or over 4G, so a screen in a shop window, a lobby or a remote site can be managed without anyone on site.
Interfaces
| Wi-Fi | Dual antennas for wireless network connection. |
| ETHERNET | Ethernet port for wired network or local control. |
| SIM CARD | Slot for a 4G SIM card for remote content updates. |
| HDMI IN | HDMI input for an external video source. |
| USB | USB port for local content and media playback. |
| SWITCH | Function / reset switch. |
| PWR / CLOUD / SYS / RUN | Status indicators for power, cloud connection, system and running state. |
Typical applications
- Indoor advertising screens and shop-window displays
- Front-desk and reception LED signboards
- Remote or unmanned LED installations updated over 4G
- Retrofitting an existing LED screen that has no on-site PC
Supplied as a single unit. For cabinet, module and control-system bundles, or for help choosing between the TB series and a synchronous solution, contact us.
