This unit is an HDMI over IP Transmitter that allows you to extend HDMI signals using the TCP/IP protocol over regular Cat.5e network cable. This extender supports the transmission of High-Definition signals (up to 1080p@60Hz) with audio up to 100m on a single cable. The transmission distance can be further extended (up to 100m per segment) by using Gigabit Ethernet network switches, allowing the user to cascade the system without signal loss or introducing delay. This Transmitter also features bi-directional IR and RS-232 pass-through.

It is also possible to for this Transmitter to operate in multicast mode, allowing you to send a single AV signal to a large number of Receivers within the same local network with no additional bandwidth cost. Additionally, that same multicast signal can be used to create large multi-display video walls with amazing simplicity.

This Video over IP system is perfect for both residential and commercial installation environments. Configuration information is provided via the On-Screen Display (OSD) on connected (but unlinked) Receivers and control is via WebGUI, Telnet, or the AV over IP Master Controller.
