How to use

Use a single Cat5e or Cat6 cable between the UTP ports of the transmitter and receiver; when distributing to multiple receivers, connect both units to an Ethernet switch according to the point-to-multipoint configuration. Plug in the supplied 5V/1A power adapters to both TX and RX units. Use the IR controllers for remote control pass-through and connect USB mouse/keyboard to the receiver USB ports for KVM control. Use the EDID button on the receiver to store display EDID when required.
Usage recommendations
For best performance, use high-quality Cat5e or Cat6 cable without excessive bends; avoid running cables near strong electromagnetic sources. When using multiple receivers through a switch, ensure the switch supports the required network bandwidth and is powered. Store receiver EDID only after connecting the intended display to prevent incorrect display settings.
