The NovaStar H Series (H2, H5, H9) are high-performance all-in-one LED display controllers widely used in live events, command centers, and fixed installations. This paper details the API capabilities of the H Series, covering TCP/IP-based command protocols, HTTP REST endpoints for third-party control, and integration with show control systems (Crestron, Extron, Q-SYS). Practical examples include input switching, layer management, preset recall, and device monitoring. novastar h series api
