CAT-Linx 3 Plus

Overview

For installation ease and convenience, CAT-Linx 3 Plus extenders have integrated power to supply endpoints over the same CATx 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 the transmitter to power both devices. The TX transmitter powers the RX receiver.

CAT-Linx 3 Plus extenders support HDCP 2.2, HDR, and multi-channel audio. In addition to built-in KVM control of remote devices, the signal extenders can control display devices using IR pass-through and bidirectional RS-232 signal transmission.

In summary, CAT-Linx 3 Plus extenders are a high-performance, feature-rich, and cost-effective solution for 4K 60Hz signal distribution with integrated KVM control of remote devices.
