    Specification sheet for the SECO-LARM ENFORCER MVE-AH1H1-42YQ 4K Enhanced HDMI Long-Range Extender, which sends HDMI video/audio plus RS-232 and bi-directional IR over a single Cat5e/6 cable up to 492ft (150m) for 1080p or 394ft (120m) for 4K2K/UHD.

    Overview

    This extender uses an active transmitter and receiver pair to send HDMI signals over a single Cat5e/6 cable. It can send 1080p signals up to 492ft (150m) between the two units with zero signal loss, and 4K2K/UHD HDMI signals up to 394ft (120m), using a single power supply on either end. The set ships complete and is plug-and-play.

    Overview — Connections

    Transmitter: Power input, HDBaseT Out, HDMI Loop-out, HDMI In, IR In, IR Out, RS-232, Link LED, Data LED.

    Receiver: Power input, HDBaseT In, HDMI Out, Audio Out, IR In, IR Out, RS-232, Link LED, Data LED.

    Sample Application

    A remote control at the AV source location controls devices via the transmitter's IR In, while a remote at the distant display location controls the source through the receiver. Only one power supply is needed — connect it at either the transmitter or the receiver, not both. Use IR IN on the transmitter with IR OUT on the receiver to control a distant HDMI display from the source side, or IR IN on the receiver with IR OUT on the transmitter to control the source from the display side.
