Part of the Omega™ Series of integration products for modern AV communications and collaboration, the OME-EX-TX is HDCP 2.2 compliant and transmits IR, RS-232, and IP control signals. With a matching HDBaseT receiver, the integrated USB extension addresses the challenge of connecting between USB devices at remote locations, and is ideal for software video conferencing and touch or interactive displays. The OME-EX-TX includes a USB 2.0 host interface for a PC, plus two peripheral devices such as a speakerphone, microphone, or keyboard and mouse. This transmitter is ideal for use with Omega Series receivers as well as switchers with HDBaseT inputs. Also available is the OME-EX-KIT which includes the OME-EX-TX and OME-EX-RX.

The OME-EX-TX incorporates many popular integration convenience features, while delivering excellent performance and value for 4K presentation and video conferencing applications. The OME-EX-TX can be remotely powered through Power over Ethernet (PoE) by the OME-EX-RX, OME-SR21, OME-PS62, or other Omega Series receiver or switcher. The Ethernet port on the OME-EX-TX is for IP pass-through with the receiver.


  • Complete system integration - The OME-EX-TX and OME-SR21 together provide a compact, yet comprehensive and cost-effective integration solution, with 4K scaling, display control, HDBaseT link testing, and audio system interfacing provided by the receiver.
  • Larger system applications - This transmitter is ideal for extending AV connectivity from an OME-PS62 in a central equipment rack to a meeting table or lectern, where presenters can easily access the system.
