You've got a control room, a warehouse floor, or an extended workstation that needs a live 4K feed, USB peripherals and a serial RS-232 link — but running three separate cables across 80 metres is a nightmare nobody signed up for. The ATEN CE820R-ATA receiver solves that with one Cat6 cable. Plug it in, lock the mounting kit to your rack or desk, and you're looking at full 4K video, stereo audio, USB and RS-232 arriving clean over HDBaseT 2.0. Full HD 1080P stretches to 150 m if your source doesn't need the full 4K headroom. Heads-up: this is the ATA variant — it carries RS-232 but does not pass Ethernet. If you need that extra gigabit link, look at the AT model instead. Ships with a power adapter, mounting kit and four foot pads so it's ready to bolt down the moment it lands on your bench
