VP−428H2 is an HDBaseT 4K transmitter/scaler with HDMI, DP and VGA inputs. VP−428H2 supports HDBaseT tunneling of Ethernet, bidirectional RS−232 and IR signals, as well as PoE to provide power to the HDBaseT receiver. It receives the selected AV signal, up−scales, down scales or bypasses the video, according to the settings selected by the user, and converts it for sending via HDBaseT, together with the tunneled data and PoE.
