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-422 is a serial communication standard that provides reliable, high-speed, and long-distance data transmission over twisted-pair cables. It supports differential signaling, which reduces noise and interference, making it ideal for broadcast, automation, and industrial control applications. Compared to RS-232, RS-422 allows for multi-device connectivity and longer cable runs, ensuring stable and efficient remote control of professional video equipment like switchers and cameras.
