The DV-9521 is a perfect solution for 4K HDMI, 1080p DVI/VGA with USB/IR/RS232 over Gigabit IP Ethernet. The system includes DV-9521T Transmitter (TX) and DV-9521R Receiver (RX). The TX connects to PC or Blu-ray player for the HDMI/DVI/VGA source, the RX connects to display, speaker, microphone, and USB devices. 

The solution is based on the standard IP technology, the TX converts input signals (HDMI/DVI/VGA, Audio, USB, …) to IP packets and Multicast/Unicast to Gigabit Ethernet switch. On the other end of RXs, receiving IP packets from Ethernet switch then converts back to HDMI/DVI/VGA, Audio, USB… and send to display, speaker, USB devices. The Encoder/Decoder engine built with Scaling function, multiple RXs are flexible to be configured as Video-Wall displays. Perfect for AV Broadcasting, KVM Matrix Control, Video-Wall applications like informational displays, entertainment, boardrooms, courtrooms, medical, military, and education digital signage.
