Binary 540 Series Slim 4K Ultra HD HDBaseT Extender B-540-EXT-70-SLIM with Bi-Directional IR and RS-232
4K behind any display.
A slim 4K Ultra HD HDBaseT extender set that sends HDMI video and audio over a single category cable, with IR and RS-232 control passing both ways between the source rack and the display.

Tight spaces make long AV runs hard.
Getting a 4K source from an equipment rack to a remote display often means fitting hardware behind a wall-mounted TV, where there is little room and no easy way to control the source.
Built for tight AV installs
The 540 Series Slim pairs 4K video distribution with control pass-through in a housing made to fit behind displays.
Reliable 4K video
Sends 4K@60Hz 4:2:0 video over HDBaseT on a single category cable.

Housing height
Slim enough to fit behind wall-mounted displays.
Ultra-slim housing
A thin 0.61" high body fits behind displays and in other tight locations.
Power over cable
Power can be sent over the cable, reducing the number of power supplies needed at the far end.
IR and RS-232 control
Bi-directional IR and RS-232 pass-through lets a source rack control the display end and the other way around.
