NovaStar TB2-4G LED Multimedia Player — Legacy Reference
The NovaStar TB2-4G is a Taurus-series player that combines stored-content playback and LED sending for screens up to 650,000 pixels. It also accepts a live HDMI source for synchronous operation. Its front Ethernet port handles the network connection; the rear LEDOUT port sends display data. Match the correct port to each cable when checking an existing system.
EagerLED lists this model as no longer in production and recommends the NovaStar TB20 Plus for replacement consideration. Confirm the live-source requirement and complete screen configuration before choosing an alternative. The replacement name alone does not guarantee identical connections or operating modes.
TB2-4G Specifications and Configuration Differences
This reference follows TB2-4G & TB2-4G (Optional 4G) Specifications V1.4.1, document NS120100612.
| LED loading | Up to 650,000 pixels; width up to 1920 or height up to 1080 pixels within that total |
|---|---|
| Playback modes | Internal content in asynchronous mode; HDMI input in synchronous mode; manual switching and HDMI priority |
| HDMI | HDMI 1.3 input; automatic full-screen scaling subject to source and screen width conditions |
| Processing and memory | Quad-core 1.2 GHz; 1 GB operating memory; 8 GB storage with 4 GB available to users |
| Video decoding | 1080p hardware decoding; separate from the LED loading limit |
| Network connections | Front Fast Ethernet network port and Wi-Fi AP; rear LEDOUT display output |
| USB and audio | Front USB 2.0 for drive import; rear Type-B for PC connection; stereo audio output |
| Cellular configuration | V1.4.1 distinguishes a supplied 4G module from the Optional 4G version without a module by default |
| Power reference | Table states 5 V DC, maximum 15 W, with a 5 V / 3 A adapter; confirm the physical unit label |
| Size and environment | 196.0 × 115.5 × 34.0 mm; IP20; −20°C to +60°C, 0–80% RH non-condensing |
Maximum width and height are independent limits. A full 1920 × 1080 canvas exceeds 650,000 pixels. Calculate the actual screen load and supply the receiving-card model, cabinet wiring and module parameters for review.
HDMI, USB and Content Publishing
For synchronous full-screen scaling, V1.4.1 specifies source width from 64 to 2048 pixels, with screen width at least 64 pixels and no wider than the original source. Confirm the complete source timing and screen layout. A supported decoder resolution does not establish support for every HDMI timing.
The rear USB Type-B connection is documented for PC screen configuration and publishing through NovaLCT and ViPlex Express on Windows. ViPlex Handy supports mobile operation. Cloud publishing and monitoring are also described for connected installations. These are historical software references: verify firmware and current software compatibility before changing a working system.
For cellular access, identify whether the installed unit includes its modem, then check regional bands, antenna and operator/SIM requirements. The product selector has separate standard and “with 4G module” options. Wired networking takes priority over 4G when both paths are available.

TB2-4G Replacement Questions
Is the 4G module included with every configuration?
No. The source distinguishes supplied-modem and Optional 4G versions, and this listing has separate configuration options. Check the exact hardware label and supplied accessories rather than relying on the shared TB2-4G name.
What power supply should an installed unit use?
The table specifies 5 V DC, while the rear-panel illustration shows a 5–12 V marking. Confirm the hardware label and matching approved adapter for that unit before connecting power. Do not choose a voltage from the illustration alone.
What should I check before replacing it with TB20 Plus?
Provide the old label, screen pixel map, receiving-card setup and network requirements. State whether the installation uses a live HDMI source or stored content, and whether PC USB publishing is required. Compare these functions explicitly with the proposed replacement.
