8. Deployment & Setup Tips of Nova H2 Processor
Here are some essential setup tips for deploying the NovaStar H2 processor:
① Network & Control Setup
Ensure the 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.
