The HDR-80/90 Control Protocol enables external control of Datavideo HDR-80 and HDR-90 recorders via RS-422, RS-232, or Ethernet (DVIP). It supports remote functions like playback, recording, and media control with a structured command format for reliability. With a 38400 bps transmission rate and TCP-based network control, it ensures seamless integration into professional AV workflows.
RS-232 is a widely used serial communication protocol for connecting devices like computers, cameras, and AV equipment. It enables reliable point-to-point data exchange over short distances (up to 15 meters) using a standard voltage-based signaling method. Though older, it remains popular for its simplicity and compatibility, making it ideal for integrating hardware in industrial and professional AV environments.
