4K HDMI IR Extender 70m

The Black Box Innovations VX-HDMI-TP-70M extends HDMI signals up to 70 metres over a single CATx cable. It supports 4K UHD resolution at 30 Hz and Full HD 1080p up to the maximum distance. The transmitter and receiver set includes IR emitter and receiver accessories for remote source control. It suits installers needing long-distance video distribution for digital signage or home theatre.

HDBaseT Lite with RS-232 and CEC

The extender uses HDBaseT Lite technology to carry video, audio, IR and serial RS-232 control over twisted pair cabling. Two RJ-45 ports connect the transmitter and receiver via Category 6 cable. HDMI input and output ports link the source and display directly. EDID copy function and HDCP compliance maintain signal integrity, while CEC passthrough simplifies device control.

Replaces short HDMI runs and active cables

This kit replaces standard HDMI cables limited to short runs and removes the need for separate IR repeater systems. It upgrades installations where 4K sources sit beyond typical cable reach, such as projector mounts or distributed audio-visual setups. The jump is worth it when cable length exceeds passive limits and bidirectional IR control is required.

Questions about this item

What HDBaseT Lite distance caps apply for 4K versus 1080p signals?

The extender delivers 4K UHD at 3840 x 2160 up to 40 m and full 1080p video plus audio, IR and RS-232 up to 70 m over a single CAT6 cable.

What cable type and HDMI port count are required for the transmitter and receiver units?

Each unit provides one HDMI input or output and one RJ-45 port; the link requires a single Category 6 twisted-pair cable between them.

How do I enable the IR control path and what common step is missed?

Connect the supplied IR emitter to the transmitter and the IR receiver to the receiver, then ensure the HDBaseT link is active; the IR path will not pass until the CAT6 link carries a valid video signal.
