KVM extender ATEN CE820L-ATA-G Wired 100m 4096x2160

The ATEN CE820L-ATA-G KVM extender uses HDBaseT 2.0 technology to transmit HDMI video, stereo audio, USB, Ethernet and RS-232 signals over a single Cat6 cable up to 100 meters. It supports a maximum digital resolution of 4096 x 2160 (4K) and offers a compact form factor with a USB Type-B port for connecting host devices. The unit is designed for wired installations that require remote access to a computer or KVM system while preserving high-resolution video and multiple signal types.

Advantages

The CE820L-ATA-G integrates HDBaseT 2.0 for stable long-distance transmission and supports 4K video at reduced frame rates, alongside stereo audio, USB and RS-232 communication. Its compact size and single‑cable setup simplify installation and reduce cabling complexity while Ethernet passthrough enables networked peripheral use.

Suitable for

• Control rooms and transportation monitoring centers
• Medical and healthcare facilities requiring centralized workstations
• Industrial environments and warehouses for remote equipment access
• Extended workstations where keyboard, video, mouse and USB devices must be accessed remotely

When it may not be suitable

This wired KVM extender requires Cat6 cabling and is limited by the specified maximum distances; environments that cannot accommodate structured cabling or require wireless extension are not suited to this product. Also, while it supports 4096 x 2160 resolution, the achievable frame rate may be lower at the highest resolutions, so applications demanding full-frame-rate 4K video may need a different solution.

Key specifications

• Maximum resolution: 4096 x 2160 pixels
• Transmission technology: HDBaseT 2.0 over single Cat6 cable
• Maximum wired distance: up to 100 meters (HDBaseT 2.0); HD 1080p signals may reach longer distances per HDBaseT capability
• Signal types: HDMI video, stereo audio, USB Type-B host connection, Ethernet passthrough, RS-232
• Form factor: compact, rack/desk-friendly unit

How to use

Connect the transmitter to the host computer using the USB Type-B port and HDMI output, then connect the receiver to the remote monitor, keyboard, mouse and USB peripherals. Run a single Cat6 cable between transmitter and receiver up to the supported distance, and provide power to both units. Configure RS-232 or Ethernet passthrough if serial control or networked peripherals are required. Verify display settings on the host to match the desired resolution.

What to consider before purchase

• Availability of Cat6 cabling and structured cabling pathways for runs up to 100 m
• Required display resolution and acceptable frame rate at 4096 x 2160
• Need for RS-232 or Ethernet passthrough and USB peripheral support
• Physical space for placing compact transmitter and receiver units

Recommendations

For stable performance, use high-quality Cat6 cable and test the display resolution on the host system after installation. In installations requiring maximum video frame rate, consider verifying whether lower resolutions or alternative extenders are more appropriate.
