Atlona Omega 4K HDMI/USB Wall Plate Transmitter (330') - AT-OME-EX-TX-WP

Product Overview

The Atlona AT-OME-EX-TX-WP is a 4K HDBaseT wall plate transmitter designed for commercial video conferencing, lecture hall AV extension, and collaborative meeting spaces requiring discreet HDMI signal distribution over structured cabling. Part of the Omega Series, this HDBaseT HDMI wall plate transmitter supports 4K/UHD video at 60 Hz with 4:2:0 chroma subsampling and extends AV, USB 2.0, RS-232 control, and power up to 330 feet (100 meters) over CAT6/6a/7 cable. The integrated USB hub makes it a purpose-built solution for Zoom, Microsoft Teams, Cisco Webex, and other UC platform deployments where a PC host and USB peripherals must share a single wall plate connection point. HDCP 2.2 compliance ensures protected content passes through authenticated devices without signal interruption.

Product Description

The AT-OME-EX-TX-WP occupies a standard US one-gang wallplate opening and ships with interchangeable black and white trim kits, allowing integrators to match the finish to any installation environment — whether a conference room table box, a lectern, a wall outlet, or a floor box. The device transmits HDMI video, embedded audio, USB 2.0 data, RS-232 control, and power over a single category cable to any compatible Omega Series receiver or HDBaseT-input switcher. At 4K/UHD resolution, the transmitter achieves 330 feet (100 meters) over CAT6/6a/7 and 295 feet (90 meters) over CAT5e, making it practical for large conference rooms, training rooms, and auditorium applications. The USB hub provides one USB Type-B port for connection to a host PC and one USB Type-A port for a peripheral device such as a speakerphone, microphone, or keyboard. Remote powering via IEEE 802.3af PoE from the downstream receiver or switcher eliminates the need for a local AC power supply at the transmitter location, significantly reducing installation complexity. RS-232 pass-through from baud rates of 2400 to 115200 allows a control system to communicate with a sink device over the same HDBaseT link. The OME-EX-TX-WP is compatible with the AT-OME-EX-RX receiver, AT-OME-SR21 switcher/receiver, and AT-OME-PS62 matrix presentation switcher. Field-updatable firmware via the USB port ensures long-term supportability in enterprise AV environments. Front panel LEDs indicate power status and HDBaseT link status at a glance, simplifying commissioning and ongoing troubleshooting.

Frequently Asked Questions

Q: What receiver or switcher is the AT-OME-EX-TX-WP compatible with?

The AT-OME-EX-TX-WP is designed for use with Atlona Omega Series HDBaseT receivers and switchers, including the AT-OME-EX-RX, AT-OME-SR21, AT-OME-RX11, AT-OME-RX21, AT-OME-RX31, and AT-OME-PS62. It is not compatible with the Atlona HDVS-300 system for USB extension. The receiver or switcher must also be HDCP 2.2 compliant to pass protected content.

Q: Does the AT-OME-EX-TX-WP require a local power supply?

No. The transmitter is powered remotely by the connected Omega Series receiver or switcher over the HDBaseT cable link using IEEE 802.3af PoE. This eliminates the need for a local AC outlet at the wall plate, table box, or floor box installation location.

Q: What USB devices are supported at the wall plate transmitter?

The transmitter provides one USB Type-B port for a host PC connection and one USB Type-A port for a single peripheral device such as a speakerphone, microphone, or keyboard and mouse. USB 2.0 devices, USB 3.0 devices operating in USB 2.0 mode, and legacy USB 1.x peripherals are supported. Maximum data rate over HDBaseT is 120 Mbps.

Q: What category cable is recommended for maximum extension distance?

CAT6, CAT6a, or CAT7 cable is recommended for the full 330-foot (100-meter) 4K/UHD extension range. CAT5e supports up to 295 feet (90 meters) at 4K/UHD. Proper RJ-45 termination and cable quality directly affect HDBaseT link reliability.

Q: Is the AT-OME-EX-TX-WP compatible with UC platforms like Zoom and Microsoft Teams?

Yes. The integrated USB 2.0 hub extension makes this transmitter well-suited for soft codec and web-based conferencing platforms including Zoom, Microsoft Teams, Cisco Webex, Skype for Business, and GoToMeeting when paired with a compatible Omega Series receiver.
