Atlona HDBaseT Wall Plate Transmitter for HDMI and USB Type-C with USB Hub - AT-OME-SW21-TX-WPC

Product Overview

The Atlona AT-OME-SW21-TX-WPC is a 2x1 wallplate HDBaseT transmitter with USB-C and HDMI inputs, designed for conference rooms, huddle rooms, and training rooms where presenters need single-cable connectivity from a table box, lectern, or wall plate to a centrally located AV system. As part of the Omega Series, it transmits 4K/UHD video up to 4K/60 4:2:0, embedded audio, USB 2.0 data, and control signals over a single CAT6/6a/7 cable run up to 330 feet (100 meters) to a compatible HDBaseT receiver or switcher. The AT-OME-SW21-TX-WPC HDBaseT wall plate transmitter is HDCP 2.2 compliant and includes an integrated USB hub for connecting a peripheral device such as a speakerphone, microphone, or keyboard, making it ideal for Zoom, Microsoft Teams, Cisco Webex, and other software video conferencing platforms. The unit is remotely powered over HDBaseT from a compatible Omega Series receiver, removing the need for a local power outlet at the installation point.

Product Description

The AT-OME-SW21-TX-WPC occupies a standard US one-gang wallplate form factor and ships with interchangeable black and white wallplates and faceplates for integration into any room finish. It can be flush-mounted into a table box, desk, lectern, or floor box, or installed as a wall plate. The USB-C input supports DisplayPort Alternate Mode for AV output plus USB 2.0 data, providing a single-cable connection to MacBook, Chromebook, Windows, and compatible mobile devices for simultaneous AV presentation and video conferencing peripheral access. The HDMI input accommodates legacy laptops and other HDMI sources. Automatic input switching selects the active source using hot plug detect and video detection. The integrated USB hub includes a USB Type-B port and a USB-C port for host PC connection, plus a USB Type-A port for a single peripheral device such as a speakerphone or microphone. USB 2.0 extension over HDBaseT supports data rates up to 120 Mbps and is compatible with USB 2.0, USB 3.0 devices operating in USB 2.0 mode, and legacy USB 1.x peripherals. Video transmission supports 4K/UHD at 60 Hz with 4:2:0 chroma subsampling and 4K/30 with 4:4:4 over HDBaseT, with compatibility for sources up to 10 Gbps data rates including Ultra HD Blu-ray players and media players. HDCP 2.2 compliance supports the full chain of protected content delivery. The AT-OME-SW21-TX-WPC is remotely powered via IEEE 802.3af PoE supplied by a compatible Omega Series receiver or switcher over the HDBaseT cable, requiring no local AC power. Display control is passed through to the connected receiver via TCP/IP, RS-232, or CEC, enabling automatic display power management from the receiver end. Integrated HDBaseT link status monitoring allows field verification or troubleshooting of the twisted pair cable run through PC software, providing detailed test reporting without specialized test equipment. A 2-meter (6.5 ft) USB-C male-to-male cable (USB 3.1 Gen 1) is included. The unit is not compatible with the Atlona HDVS-300 system for USB extension.
