Commissioning Workflow
Hardware Cabling ───> Front-Panel Quick Setup ───> NovaLCT Screen Mapping ───> Layer & Preset Saving
`
1. Hardware Interconnection and Signal Cabling:
· Mount the VX400 Pro into an equipment rack or AV flight case using standard 1U brackets.
· Connect live video sources: plug your primary presentation computer into HDMI, your live camera feed into 3G-SDI, and your media server into DVI.
· Connect Cat5e or Cat6 shielded cables from Gigabit Ethernet Output Ports 1 through 4 to the corresponding cabinet runs.
· If driving a remote stage over fiber optic lines, insert 10G SFP optical modules into OPT 1 and connect a single-mode or multi-mode optical cable to a NovaStar CVT10 converter at the stage.
2. Fast Front-Panel Rotary Knob Screen Configuration (No PC Required):
· Power on the unit. On the front-panel OLED display, press the rotary knob to enter the main menu.
· Select Screen Settings -> Quick Configuration.
· Set Cabinet Row Quantity and Cabinet Column Quantity to match your physical LED wall structure.
· Specify the exact Cabinet Width and Cabinet Height in pixels.
· Select the Port Offset and cable connection flow (such as top-left to bottom-right). Press the knob to send parameters; the LED screen lights up instantly.
3. Advanced Screen Mapping via NovaLCT (PC Method):
· Connect a USB Type-B cable from the rear USB port to your laptop running NovaLCT.
· Log in as Advanced Synchronous System User (default password admin).
· In Screen Configuration -> Screen Connection, visually drag and assign Ethernet ports 1 through 4 across the cabinet grid.
· Click Send to Hardware to verify the live display, then click Save to solidify configuration into non-volatile memory.
4. Configuring Multi-Layer Picture-in-Picture (PIP):
· On the front panel or within NovaLCT, navigate to Layer Settings.
· Enable Layer 1 for your primary stage background feed (such as HDMI graphic loop).
· Enable Layer 2 (PIP), select the 3G-SDI camera input as the source, and position the camera window in the top-right corner with custom scaling and border thickness.
5. Preset Saving and Instant Live Switching:
· Save custom multi-source layouts as scene presets (such as Keynote Speech, Video Playback, Camera Live Feed, and Podium Dual View).
· Use the illuminated front-panel preset buttons for instant, seamless cut or fade transitions during live events.

4. Professional Review: Strengths and Engineering Considerations
Key Advantages:
· True 2-in-1 Architecture: Combines a professional video processor, video scaler, and 4-port LED sending card into a single lightweight 1U box, eliminating extra processing gear and reducing rental truck weight.
· Dual 10G Optical SFP Ports: Built-in OPT ports replicate Ethernet outputs directly, enabling noise-immune long-distance transmission up to several kilometers without buying separate optical transmitters.
· Computer-Free Quick Setup: The front-panel rotary knob and OLED screen allow rental technicians to re-configure cabinet layouts in under two minutes directly at the stage.
· Broadcast Genlock Synchronization: Frame-accurate Genlock locking ensures multi-controller spliced screens remain perfectly synchronized with zero frame tearing during high-motion camera pans.
Important Engineering Considerations:
· Port Pixel Budget Management: Each Gigabit Ethernet port handles up to 650,000 pixels at 60 Hz; distribute cabinet runs evenly across all four ports to maintain balanced frame rates.
· Fiber Transceiver Compatibility: When utilizing the OPT ports, ensure matched SFP transceiver modules (single-mode or multi-mode) are installed on both the VX400 Pro and the receiving CVT10 unit.
