Atlona 4K HDR Transmitter w/IR, RS-232, Ethernet, and PoE.

The Atlona AT-HDR-EX-100CEA-TX is an HDBaseT™ transmitter designed to extend 4K and high dynamic range content alongside audio, Ethernet, control, and power. It supports 4K/UHD video at 60 Hz with 4:4:4 chroma sampling and HDR data. These signals can travel up to 330 ft (100 m) over Category 6/6A cable, giving system designers a defined long-distance transmission option for installations requiring more separation between connected equipment.

Ideal Use Cases

This model is suited to systems that must carry 4K/UHD 60 Hz video over distances beyond a conventional local equipment connection. Its 330 ft (100 m) transmission range supports layouts in which source equipment and the receiving location cannot be positioned together.

It is also appropriate when video is only one part of the required signal path. The transmitter supports multi-channel audio, Ethernet, IR, RS-232 control signals, and power in addition to HDR video. This combination addresses installations that need media, network communication, device control, and power carried over Category 6/6A cabling.

Why Choose This Model

The AT-HDR-EX-100CEA-TX combines extended transmission distance with detailed 4K image support. Its ability to handle 4K/UHD at 60 Hz with 4:4:4 chroma sampling is especially relevant when preserving full color information is part of the system requirement. HDR data is carried with the video signal, supporting high dynamic range content without separating it from the extended video path.

Integrated transport for multi-channel audio and Ethernet expands the transmitter beyond video-only extension. IR and RS-232 provide two control options, while PoE adds power support. Bringing these capabilities together can reduce the need to plan separate transmission paths for every supported signal type.

Installation and Integration

The specified transmission medium is Category 6 or Category 6A cable, with a supported extension distance of up to 330 ft (100 m). Installers can use this stated cable and distance information when planning the route between the transmitter and the rest of the HDBaseT system. The total link length should remain within the documented maximum.

The model supports Ethernet, IR, and RS-232 alongside video and audio, allowing those functions to be considered within the same integration plan. PoE support also makes power part of the available HDBaseT feature set. No additional connector counts, power direction details, or compatibility specifications are provided in the source data, so those requirements should be confirmed for the complete system before installation.

Performance Highlights

• Extends 4K/UHD video at 60 Hz.
• Supports 4:4:4 chroma sampling.
• Carries HDR data with the video signal.
• Transports multi-channel audio.
• Supports Ethernet, IR, and RS-232 control.
• Includes PoE support.
• Reaches up to 330 ft (100 m) over Category 6/6A cable.

The stated video capabilities center on detailed 4K/UHD transmission at 60 Hz. The combination of 4:4:4 chroma sampling and HDR data support provides a clearly defined performance profile without relying on unspecified video formats, HDR standards, or audio codecs.

What Makes It Different

The primary distinction of the AT-HDR-EX-100CEA-TX is the breadth of signals it supports over its Category 6/6A transmission path. Instead of addressing only 4K video extension, it combines HDR data, multi-channel audio, Ethernet, IR, RS-232, and power within one transmitter platform.

Its 330 ft (100 m) reach is paired with a specific high-resolution signal capability: 4K/UHD at 60 Hz with 4:4:4 chroma sampling. This makes the model identifiable by both its transmission distance and its supported video detail, rather than distance alone.

Final Assessment

The Atlona AT-HDR-EX-100CEA-TX is a focused choice for HDBaseT systems requiring long-distance 4K HDR transmission and integrated supporting signals. It extends 4K/UHD 60 Hz 4:4:4 video, HDR data, multi-channel audio, Ethernet, control, and power up to 330 ft over Category 6/6A cable. Its combined IR, RS-232, Ethernet, and PoE capabilities make it particularly relevant when these functions must be incorporated into the same planned extension path.
