The NovaStar H Series API is a specialized toolset designed for third-party developers to programmatically control NovaStar's flagship all-in-one video splicing processors. By leveraging the NovaStar H Series OpenAPI, integrators can automate complex video wall tasks such as preset switching, layer management, and device status monitoring. Core Integration Protocols

The H Series supports multiple communication methods to fit different system architectures:

UDP Protocol: Most control systems (like Crestron or Bitfocus Companion) use UDP port 6000 for high-speed command delivery. Commands are typically sent as JSON strings wrapped in square brackets (e.g., ["cmd": "..."]).

HTTP/JSON API: Modern web-based integrations often use the Open API connector, which provides a structured HTTP interface for cross-platform control via Windows, Mac, or mobile devices.

RS232 Serial: For legacy systems, the H Series retains support for serial communication, allowing direct wired control from specialized AV hardware. Key API Capabilities

The API allows for deep manipulation of the hardware's internal functions: H Series - Global leading LED display control solution

The NovaStar H Series API is a robust control interface designed for professional systems integrators who need to automate and manage high-end video wall processors. It primarily uses the HTTP/RESTful protocol, making it highly compatible with modern control systems like Crestron, AMX, and Q-SYS. Core Capabilities

The API allows for comprehensive remote management of the H Series (H2, H5, H9, H15) frames without requiring the physical front panel or the web-based GUI:

Preset Switching: The most common use case; trigger saved layouts and configurations instantly. Unlocking the Power of Novastar H Series API:

Input/Output Management: Query the status of cards, switch signal sources, and manage resolutions.

Layer Control: Dynamically adjust layer positioning, sizing, and priority (Z-order) on the video wall.

System Monitoring: Retrieve real-time data on hardware health, including temperature, power supply status, and card connectivity.

Brightness & Color: Adjust global or screen-specific visual parameters programmatically. Strengths

Standardized Integration: Because it utilizes standard HTTP commands (GET/POST), it is easy for developers to test using tools like Postman before deploying code.

Granular Control: Unlike simpler controllers, the H Series API provides deep access to the modular nature of the hardware, allowing for specific control over individual sub-cards.

Low Latency: Command execution is generally snappy, essential for live event environments where visual transitions must be precise. Considerations for Developers

Documentation Access: NovaStar typically provides the API documentation upon request or via their support portal. It is not always publicly "indexed" like open-source projects.

Security: Implementers should be mindful of network security, as the API allows for significant changes to the visual output; it is best kept on a dedicated, secured AV VLAN.

Version Dependency: Ensure your firmware version matches the API documentation version, as new features (like 16-bit support or specific HDR functions) often require updated command sets. Verdict

The NovaStar H Series API is an essential tool for enterprise-level AV deployments. While the web GUI is excellent for setup, the API is what transforms the H Series from a standalone processor into a fully integrated component of a smart building or broadcast studio.

Key Capabilities of the API

Input Source Switching: Change between HDMI, DP, SDI, or DVI inputs remotely.
Preset Recall: Load saved display configurations (e.g., "Presentation Mode" vs. "Bright Storefront Mode").
Brightness & Gamma Control: Adjust real-time visual parameters.
Sending Card Status: Monitor temperature, voltage, and signal health of connected sending cards.
EDID Management: Read or force EDID for connected sources.
Scale & Position: Adjust window cropping, position, and size without physical interaction.

The Architecture of the H Series API

At its core, the H Series API is a communication protocol that allows external software applications to communicate directly with NovaStar’s H Series receiving cards over a network (typically TCP/IP). Unlike traditional systems that rely solely on a dedicated controller or a PC-based application like SmartLCT, the API exposes a set of programmable endpoints. These endpoints allow developers to query status, adjust parameters, and execute diagnostic routines. Device Control : The API allows developers to

The H Series cards themselves are intelligent slave devices. Through the API, a master system (e.g., a show control PC, a building management system, or a Python script) can send structured commands—often in JSON or binary protocol format—to read temperature sensors, monitor voltage levels, adjust gamma curves, or apply coefficients for specific LED modules. The API operates at a low enough level to affect hardware states but is abstracted enough to prevent catastrophic damage (critical parameters like voltage thresholds are typically read-only or require authentication).

Part 7: Troubleshooting the H Series API

Even with perfect code, the physical network matters. Here are the three most common failures:

3.2 Get Device Info (Model, Firmware, S/N)

CMD: 0x10
Request: AA AA AA 02 10 12 BB BB BB
Response (example): AA AA AA 0C 90 48 32 5F 56 31 2E 33 2E 30 ... (ASCII "H2_V1.3.0")

3.3 Example TCP Session (Python)

import socket
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(("192.168.0.10", 5000))
sock.send(b"GIn\r\n")
resp = sock.recv(1024).decode()
print(f"Current input: resp")  # ACK 0 2
sock.send(b"SIn 1\r\n")
print(sock.recv(1024))  # ACK 0
sock.close()

4) Example command flows (generic)

Note: specific byte formats vary by firmware version. Consult your device’s protocol reference for exact packet formats.

Read device info (pseudo-UDP):
1. Send discovery broadcast packet to UDP port X.
2. Parse reply for device IP, model, firmware.
Set brightness (pseudo-TCP):
1. Connect to device at TCP port Y.
2. Send “set brightness” command with level 0–100 (or 0–255).
3. Wait for ACK; optionally poll current brightness to confirm.
Update network settings (HTTP or TCP):
1. Authenticate via web UI or use plain TCP command.
2. Submit static IP, mask, gateway.
3. Device may reboot — wait and re-discover.
Upload panel configuration (mapping):
1. Prepare mapping file (cabinet rows/cols, pixel order).
2. Send via TCP in chunks or use web UI “import”.
3. Validate with a test pattern and per-cabinet health checks.
Firmware upgrade:
1. Upload firmware file (HTTP POST or TCP transfer).
2. Trigger firmware flash command.
3. Monitor upgrade progress; do not power cycle until confirmed.
