The Atlona AT-OME-ST31 is a 3×1 switcher and HDBaseT transmitter with HDMI and USB-C inputs. Part of the Omega™ Series of integration products for modern AV communications and collaboration, the OME-ST31 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 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 1080 @ 60, 30, or 24 Hz is available for the HDMI output when connected to an HD sink. The OME-ST31 is designed for use with Omega Series receivers and switchers, select HDVS Series receivers such as the AT-HDVS-SC-RX scaler, the AT-UHD-EX-100CE-RX receiver, and other Atlona switchers with HDBaseT inputs.
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 through Power over Ethernet (PoE). With the optional power supply, the OME-ST31 can provide PoE powering to a compatible receiver, and also charge laptops and mobile devices through the USB-C port. For additional integration convenience, the OME-ST31 features analog audio embedding (to replace the HDMI or USB-C input audio), control via TCP/IP and RS-232, RS-232 insertion over HDBaseT, and remote management with Atlona Management System (AMS).
Automatic Display Control
The OME-ST31 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-ST31 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-ST31 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-ST31 display control capability can also be triggered by an external control system.
* Consumer Electronics Control (CEC): Atlona does not guarantee the function of CEC with all televisions. We can confirm proper operation with many current Samsung, Panasonic, Sony, and LG TVs. Many manufacturers do not support the CEC “off” command when sent from a source and older TVs use proprietary commands. Atlona only supports those TVs that follow CEC command structure from HDMI 1.2a and support the “off” command when issued by a source. We encourage any dealer to get evaluation product from Atlona prior to designing a system around this control technology or be prepared to use other methods to control their displays if Atlona CEC is not compatible with the installed displays.
The OME-ST31 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.
- Complete system integration – The OME-ST31 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-ST31 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.
The AT-OME-ST31 is ideal for 4K/UHD extension to the AT-UHD-EX-100CE-RX-PSE or AT-UHD-EX-100CE-RX receiver, and can also provide remote 4K/UHD input switching for Atlona HDBaseT-equipped switchers and matrix switchers. Additionally, the AT-OME-ST31 is compatible with the AT-HDVS-200-RX receiver and HD scaler, and the AT-HDVS-SC-RX receiver and 4K/UHD scaler.
