ATEN CE820 USB HDMI HDBaseT 2.0 KVM Extender

Overview

The ATEN CE820 is the receiver unit of the CE820 USB HDMI HDBaseT 2.0 KVM Extender system, designed to push 4K video and USB keyboard/mouse control up to 100 meters over a single Cat 6 or Cat 6a cable — eliminating the need to co-locate workstations with displays in server rooms, control suites, or broadcast environments. At 4K resolution (4096×2160 or 3840×2160 @ 60Hz in 4:2:0, or @ 30Hz in 4:4:4), the CE820 handles both high-refresh digital signage and precision color-critical workflows where chroma subsampling matters. Drop to 1080p and Cat 5e extends the same 100m run, giving installers flexibility on cabling infrastructure already in place. The onboard RJ-45 link port (unit-to-unit) carries the HDBaseT 2.0 signal; a dedicated wakeup button on the receiver lets operators power-on remote systems without returning to the transmitter end.

Compatibility

The CE820 functions as the remote (receiver) unit and pairs exclusively with its transmitter counterpart in the ATEN CE820 system. It is part of the broader ATEN KVM extender and switch line. Note the variant distinction: the CE820-AT supports Ethernet pass-through over the HDBaseT link; the CE820-ATA does not — confirm your SKU suffix before ordering if LAN extension is required. Cable selection directly affects performance: Cat 5e supports 4K up to 90m and 1080p up to 100m; Cat 6, Cat 6a, or ATEN's own 2L-2910 Cat 6 cable reaches full 100m at 4K. For installations where structured cabling already runs Cat 5e to the endpoint, plan for the 90m 4K ceiling. Pair with a compatible KVM switch upstream if multi-source switching is needed at the transmitter end. For longer runs or fiber-based infrastructure, review other models in the KVM extender category.

Installation Notes

Humidity tolerance is rated 0–80% RH non-condensing — suitable for conditioned server rooms and control rooms, but not unventilated outdoor enclosures or high-moisture plant floors. Firmware updates are applied via the onboard slide switch; no software tool is required for field upgrades. A structured cabling run using Cat 6 or Cat 6a is recommended to hit the 100m 4K ceiling and leave headroom for patch panel insertion losses. Terminate cabling to T568B standard and verify continuity before commissioning to avoid signal-quality issues at 4K bandwidth.
