Here are some essential setup tips for deploying the NovaStar H2 processor:

（1）Network & Control Setup

Ensure the NovaStar H2 and your control PC are on the same subnet (default IP: H2 is 192.168.0.10; PC should be 192.168.0.x). Connect via Ethernet—either directly or through a switch—for both control and multiviewer monitoring.

（2）Screen Layout & EDID Configuration

In the Web UI:

• Go to Settings→ EDID Management to set both input and output resolutions (standard or custom).
• For fiber output cards, configure the connector mode first on the Device page, then set EDID.

（3）Screen Mapping

Use the Configuration → New Screen function to define rows and columns based on your physical wall. Drag and drop output ports to map them correctly, then Save.

（4）Nova LCT Sync (Optional)

Use Nova LCT to coordinate configurations across units. Enable Advanced Synchronous System, log in, and push settings to all H2 devices.

（5）Enable Genlock / Frame Sync

If deploying multi-unit walls, enable Genlock in/loop under Settings, for smooth visuals with no tearing.

（6）Use Presets & MultiViewer

Create presets (backgrounds, OSD, layers) for fast layout switching. Enable Multiviewer to monitor inputs/outputs in real time via front panel or browser.

（7）Firmware, Backup & Roles

Regularly update firmware via the Web UI or USB. Export your system configuration to a USB for quick recovery or duplication. Add user roles with specific permissions via Permission Management for secure multi-user environments.
