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 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.

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.
