Overview
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.
