Novastar H Series Api -

What (preset recall, source switching, or layer resizing) are you trying to automate?

The H Series OpenAPI Instructions document outlines a comprehensive set of commands categorized by device function. A. Device Management

Every command must terminate with a specific delimiter (usually a semicolon ; or a carriage return \r\n ) to signal the H-Series processor to execute the instruction. Key Capabilities of the API

| Feature | H Series (Modern) | S Series (Legacy) | | :--- | :--- | :--- | | | Video Processor + Sending Card Integrated | Separate Sending Card (PCIe or Standalone) | | Primary Control | ViPlex / VNNOX / Web UI | NovaLCT (Desktop Software) | | API Access | Cloud-First (REST API) | Local-First (Binary SDK) | | Ease of Integration | High (Standard HTTP/JSON) | Medium/High (Requires TCP Socket handling) | | Real-time Latency | Low (Local TCP) / High (Cloud) | Very Low (PCIe Bus or Local TCP) |

The H-Series API functions primarily over standard network protocols, allowing developers to send commands from any network-connected device. 1. Communication Protocol novastar h series api

The "cmd":"W0605" string is the core instruction, while the deviceId , screenId , and presetId parameters allow for precise targeting of presets across multiple devices and screens. For example, a command for a different preset might look like: ["cmd":"W0605","deviceId":0,"screenId":0,"presetId":1] .

For developers and integrators, mastering these APIs unlocks the full potential of NovaStar H Series processors—enabling seamless automation, remote management, and real‑time responsiveness that meet the demands of today’s most critical display applications. As LED video walls continue to grow in scale and complexity, the ability to control them programmatically will become not just an advantage, but a necessity.

The is a network-based protocol designed for intelligent, automated control of NovaStar H-series splicers. Using a RESTful HTTP/HTTPS approach (commonly utilizing POST requests), it allows external control software (like Crestron, Q-SYS, or custom applications) to interact directly with the device. Key Benefits of the API:

Ensure the control computer and the NovaStar H Series processor are on the same local network subnet. What (preset recall, source switching, or layer resizing)

The H Series supports two primary methods for external programmatic control:

The blue glow of the server room was the only light in the arena as Elias sat huddled over his laptop. In six hours, the World Championship opening ceremony would begin, but the massive 360-degree LED wrap—the centerpiece of the show—was dark.

Update network settings (HTTP or TCP):

Switch physical input sources (e.g., HDMI, DVI, 3G-SDI, IP stream) to specific output channels. Modify input resolution and frame rate parameters. Device Management Every command must terminate with a
