Atlona 4K/UHD HDMI over HDBaseT Transmitter - Ethernet, Control, & PoE - AT-UHD-EX-100CE-TX

Product Overview

The Atlona AT-UHD-EX-100CE-TX is a 4K/UHD HDBaseT transmitter designed to extend HDMI signals up to 330 feet (100 meters) over a single category cable in commercial AV installations. It is the ideal solution for long-distance 4K HDMI extension over HDBaseT in boardrooms, conference rooms, and training facilities that require full AV, Ethernet, and control signal distribution from a central equipment rack to remote displays and projectors. This HDBaseT Class A certified transmitter supports HDCP 2.2 and delivers video up to 4K/UHD at 60 Hz alongside RS-232 and IR control pass-through, making it a complete signal extension solution for integrators.

Product Description

The Atlona AT-UHD-EX-100CE-TX transmits 4K/UHD video at up to 60 Hz with embedded multi-channel audio over category cable, reaching distances of up to 330 feet (100 meters) with CAT6a or CAT7 cable and up to 230 feet (70 meters) with CAT5e/6. It is HDCP 2.2 compliant and supports 4K HDR10 at 24 Hz, making it compatible with Ultra HD Blu-ray players and high-end media sources. The transmitter extends 100Base-T Ethernet, bidirectional RS-232, and 12-volt IR control signals alongside the video and audio, eliminating the need for separate control cable runs from the AV rack to the display location. As a Power Sourcing Equipment (PSE) device, the AT-UHD-EX-100CE-TX provides Power over Ethernet to compatible receiving devices such as the AT-UHD-EX-100CE-RX, eliminating the need for a local power outlet at the display end. The quarter rack-width metal enclosure is designed for installer convenience, with rear panel I/O connectors for clean wire management and mounting brackets that allow four transmitters to share a single 1U rack tray. A front-panel USB port enables easy firmware updates without disassembly. The unit includes power chaining capability, allowing multiple transmitters in a system to be powered from a single power supply, further reducing rack infrastructure costs. The AT-UHD-EX-100CE-TX is certified by the HDBaseT Alliance and is compatible with Atlona switchers and matrix switchers featuring HDBaseT inputs, including the AT-UHD-CLSO-824 and AT-UHD-SW-5000ED. Available from Creation Networks, this transmitter is well suited for any installation requiring reliable, long-distance 4K AV and control signal distribution.

Key Features

• 4K/UHD at 60 Hz over HDBaseT — Transmits video up to 3840×2160 or 4096×2160 at 60 Hz (4:2:0) over a single category cable, supporting the highest-resolution displays in commercial AV environments.
• 330-foot (100-meter) transmission distance — Reaches up to 100 meters over CAT6a/7 at 4K, and up to 100 meters over CAT5e/6 at 1080p, providing flexibility for large-venue installations.
• Power over Ethernet (PoE) sourcing — Supplies 48V PoE to the paired receiver, eliminating the need for a local AC outlet at the display end and reducing total installation cost.
• HDCP 2.2 compliance — Adheres to the latest content protection specification, ensuring compatibility with 4K Ultra HD sources and protected content streams.
• Ethernet, RS-232, and IR pass-through — Extends 100Base-T Ethernet, bidirectional RS-232, and 12V IR control commands alongside AV, removing the need for separate control cable infrastructure.
• 4K HDR10 support — Extends 4K HDR10 at 24 Hz with 4:2:0 chroma subsampling and 10-bit color depth for compatibility with Ultra HD Blu-ray and HDR content sources.
• Multi-channel audio support — Passes PCM 2.0, LPCM 5.1/7.1, Dolby Atmos, DTS:X, Dolby TrueHD, and DTS-HD Master Audio without compression or downmixing.
• Quarter rack-width enclosure — Low-profile, 25 mm-high form factor allows four units to share a single 1U rack tray, maximizing rack efficiency in head-end equipment rooms.
• Rear-panel I/O connectors — All signal connections located on the rear panel simplify cable management and reduce visible clutter in rack installations.
• HDBaseT Alliance certified — Verified interoperability with HDBaseT-equipped displays, projectors, and compatible Atlona switchers and matrix switchers.

Frequently Asked Questions

Q: What category cable is recommended for 4K transmission at full 100-meter distance?

CAT6a or CAT7 shielded twisted pair cable is required to achieve the maximum 100-meter (328-foot) transmission distance at 4K/UHD resolution. CAT5e or CAT6 cable supports 4K up to 70 meters (230 feet) and 1080p up to 100 meters.

Q: Does the AT-UHD-EX-100CE-TX require a power outlet at the display end?

No. The AT-UHD-EX-100CE-TX is the Power Sourcing Equipment (PSE) in the pair. It provides 48V Power over Ethernet to the AT-UHD-EX-100CE-RX receiver over the HDBaseT cable, so no local AC outlet is needed at the display or projector end.

Q: Which Atlona switchers are compatible with this transmitter?

The AT-UHD-EX-100CE-TX is compatible with Atlona switchers and matrix switchers that feature HDBaseT inputs, including the AT-UHD-SW-5000ED and the AT-UHD-CLSO-824 series. It is also ideal for extending AV directly to displays with built-in HDBaseT inputs.

Q: Does this transmitter support 4K HDR content?

Yes, the AT-UHD-EX-100CE-TX supports 4K HDR10 at 24 Hz with 4:2:0 chroma subsampling and 10-bit color depth. HDR10 at 60 Hz is not supported. The source signal is typically delivered from an Ultra HD Blu-ray player at 4K/24 Hz.

Q: Can IR control be passed through to control a display at the far end?

Yes. The transmitter includes a 4-pin captive screw IR connector that passes 12-volt IR signals to the receiver end, allowing IR commands from a control system or local IR receiver to control the remote display or projector.

Q: Is this transmitter part of a complete extension kit?

The AT-UHD-EX-100CE-TX is the transmitter unit only and pairs with the AT-UHD-EX-100CE-RX receiver. Both units are available individually from Creation Networks for installations that require a transmitter-only or receiver-only replacement.

Q: How many transmitters can fit in a standard 1U rack space?

Four AT-UHD-EX-100CE-TX transmitters can be mounted in a single 1U rack tray using the included mounting brackets and the optional AT-RACK-1RU-ME multi-extender shelf, keeping rack space usage efficient in head-end equipment rooms.
