The Architecture of ControlThe H Series API utilizes standard communication methods, primarily operating over TCP/IP (typically via UDP port 6000) or RS232. This allows developers to send structured commands and receive JSON-formatted acknowledgments or data readouts.
Command Execution: When a control system sends a valid string, the H Series responds with a confirmation (e.g., "ack":"Ok").
API Management: Within the device's web console, users can manage "Open API Projects," where the system generates unique project IDs and secret keys to secure external control access.
Core Functionalities and Use CasesThe API provides deep access to the H Series’ modular features, enabling remote execution of several critical tasks:
Preset Management: Integrators can program external touch panels to instantly recall specific visual layouts or "presets".
Layer and Source Control: API commands allow for the real-time adjustment of layer positions, sizes, and input source switching across multiple 4K and 2K layers.
Status Monitoring: Developers can query the device for health metrics, including temperature, fan speed, and signal connection status, ensuring high reliability in 24/7 mission-critical environments.
Benefits to System IntegrationThe availability of a robust API simplifies the AV ecosystem in three major ways:
Reduced Complexity: By centralizing control into a single API-enabled unit, technicians can eliminate the need for multiple intermediate controllers.
Custom User Experiences: Programmers can design bespoke interfaces on mobile or desktop platforms that interact directly with the H Series hardware. Technical Paper: Control and Integration of NovaStar H
