The CH-517RXHS is an HDBaseT Receiver Scaler designed to scale the incoming video signal first, before outputting to its HDMI port. There is an Optical port providing additional audio extraction feature. Besides video and audio from the Transmitter, it also takes in 2-way IR, RS-232 and bidirectional LAN serving, over a single run of CAT5e/6/7 cable at a distance up to 100 meters. Control is via on-panel buttons or IR remote control and there is an On-screen Display (OSD) providing selection and system information. The device provides a full range of output resolutions, up to 1080p and WUXGA (RB). The bidirectional Power over Ethernet (PoE) function provides greater flexibility in installations.
