CAT-Linx 3 Signal Extender

Compact 4K Ultra HD Endpoints

CAT-Linx 3 extenders transmit signals up to 4K Ultra HD at 60Hz using conventional CAT 5e/6 cable. CAT-Linx 3 units can transmit HD signals up to 100 meters and 4K Ultra HD signals up to 70 meters. Transmit (TX) and Receive (RX) endpoints are compatible with all RGB Spectrum wall processors, multiviewers, switchers, and AV devices from other manufacturers.

For installation ease and convenience, CAT-Linx 3 extenders have integrated power-over-CATx to supply endpoints over the same CAT5e/6 cable that carries the video and data signals. This eliminates the need for external power connections. A CAT-Linx 3 pair needs only one power supply connected to either the transmitter or the receiver end to power both devices. Compact, space-saving size allows attaching receivers directly to the back of displays.

CAT-Linx 3 extenders offer a bevy of advanced features, including HDCP 2.2, Dolby and DTS HD audio support, and serial and IR control of display devices. The signal extenders provide a cost-effective way to control signal sources and displays. You can control a source from the display location or control the display from the signal source location via the CAT-Linx 3’s IR pass-through function. Bi-directional RS-232 signal transmission between endpoints is also available for serial control of display devices.

A mounting rack which holds 10 RX or TX units is available. CAT-Linx 3 extenders are a high performance, feature-rich, and cost effective solution for signal distribution, for both small-scale and large-scale installations.
