You've got a control room, a monitoring station, or a patient-facing display that needs to sit well away from the source. Running separate HDMI, USB, audio and Ethernet cables across a floor is messy, unreliable, and a maintenance headache when something drops.
The ATEN CE840 kills that problem with one Cat 6A cable. Local unit here, remote unit there, up to 100 metres apart, and you get uncompressed True 4K video (3840×2160 @ 60 Hz 4:4:4 or 4096×2160 @ 60 Hz 4:4:4), full audio, RS232 serial, Ethernet and USB all on that single run. No compression. No latency. HDR 10+ included.
Need to reach the keyboard and mouse from both ends? Two USB ports handle dual console operation. Push a button, switch control between local and remote, done. Front-panel LEDs tell you which end is active at a glance. Each unit also has its own HDMI out for local monitoring plus two USB 2.0 ports for peripherals.
Audio pass-through covers LPCM 7.1CH, Dolby TrueHD, Dolby Digital Plus and DTS-HD Master Audio, so whatever the source is pushing, the remote end hears it clean.
Built for data centres, factory floors, warehouses, healthcare imaging suites – anywhere precise signal integrity matters more than a cheap adapter on a shelf.
In the box: local unit, remote unit, 1.8 m HDMI cable, 1.8 m mic cable, 1.8 m speaker cable, 1.8 m USB-A to USB-B cable, two mounting kits, eight foot pads, two power adapters with cords, and the user guide. ATEN recommends their 2L-29330 Cat 6A cable for the run.
