Atlona AT-OME-ST31A Three-Input Switcher for HDMI and USB-C

About: Atlona AT-OME-ST31A Three-Input Switcher for HDMI and USB-C

The Atlona AT-OME-ST31A is a 3×1 switcher and HDBaseT transmitter designed for remote powering, with HDMI and USB-C inputs. The OME-ST31A features two-channel audio de-embedding to an analog balanced audio output. Part of the Omega Series of integration products for modern AV communications and collaboration, the OME-ST31A features mirrored HDMI and HDBaseT outputs and is HDCP 2.2 compliant. The USB-C input is ideal for AV interfacing with newer Mac, Chromebook, and Windows PCs, as well as smartphones and tablets. Video signals up to 4K/60 4:2:0, plus embedded audio, control, and Ethernet can be transmitted over HDBaseT up to 330 feet (100 meters). All inputs and the local HDMI output support 4K HDR and 4K/60 4:4:4 at HDMI data rates up to 18 Gbps. Additionally, 4K downscaling to 1080p @ 60, 30, or 24 Hz is available for the HDMI output when connected to an HD sink. The OME-ST31A is designed for use with Omega Series receivers and switchers. See the Related Products tab for specific product compatibility.

All-in-One Switcher, Controller, and Extender

This switching transmitter can serve as an integral component of a fully automated AV system, with the convenience of automatic input selection and display control. It can be remotely powered by Atlona HDBaseT-equipped devices. With the optional AT-PS-245-D4 power supply, the OME-ST31A can charge laptops and mobile devices through the USB-C port. For additional integration convenience, the OME-ST31A features TCP/IP and RS-232 control, RS-232 insertion over HDBaseT, and remote management with Velocity Device Manager.

Automatic Display Control

The OME-ST31A provides control to a display through TCP/IP, RS-232, or CEC*, without the need for a separate control system. This simplifies system design and integration while reducing costs. With automatic display control, the OME-ST31A can trigger a display to power on automatically whenever a laptop or other device is connected. At the end of the presentation, when the presenter disconnects the laptop, the OME-ST31A forces the display to power off. Ease of presenter interaction with the system, and the savings incurred by automatic display shutdown provide a significant return on investment. The OME-ST31A display control capability can also be triggered by an external control system.

• * Consumer Electronics Control (CEC):  Atlona only supports those TVs that follow CEC command structure from HDMI 1.2a and support the “off” command when issued by a source. Can confirm proper operation with many current Samsung, Panasonic, Sony, and LG TVs.

Reliable Auto-Switching

The OME-ST31A automatically selects an input source based on detection of the 5 volt hot plug detect (HPD) signal, as well as active video. This ensures reliable auto-switching operation for all video sources, including DVRs, DisplayPort / Mini DisplayPort adapters, and other devices that always maintain the HPD line at the 5 volt “high” state but may not be delivering active video.

Applications

Complete system integration – The OME-ST31A and a compatible HDBaseT receiver provide a compact, yet comprehensive and cost-effective integration solution. When installed below a meeting table, the available Pocket 3H (AT-PKT-3H) provides convenient tabletop AV cable access for easy BYOD connectivity.

Larger system applications – The OME-ST31A is ideal for extending AV connectivity from a central equipment rack to a meeting table or lectern, where presenters can easily access the system.

Auditoriums and lecture halls – This switcher can be used for presenting 4K video content through the projector, while also optimizing for a 1080p confidence monitor.

Product compatibility

The AT-OME-ST31A is ideal for 4K/UHD extension to the AT-UHD-EX-100CE-RX-PSE receiver, and can also provide remote 4K/UHD input switching for Atlona HDBaseT-equipped switchers and matrix switchers. Additionally, the AT-OME-ST31A is compatible with the AT-HDVS-200-RX receiver and HD scaler, and the AT-HDVS-SC-RX receiver and 4K/UHD scaler.

The AT-OME-ST31A is available as the AT-OME-ST31A-KIT with the AT-UHD-EX-100CE-RX-PSE.
