sink device status. The two video inputs can be controlled by the front panel or an external controller.
The HDC-RH221UHD/HDC-RH421UHD also features Daisy chain for extending and distributing video,
audio, and control signals. In addition, digital audio signals can be de-embedded onto the analog output
signals. It supports bidirectional RS-232C and LAN communication.
