How to use

Connect the transmitter (Tx) to the HDMI source and the receiver (Rx) to the display, then link the two units with Cat5e/Cat6 cable. Connect the provided PSU to the designated unit; two-way POC allows power to be shared between Tx and Rx when supported. Configure IR or RS-232 connections for remote control and device management as required, and verify CEC settings on connected devices for control over HDMI.

Recommendations

For optimal performance use high-quality Cat6 cable for longer runs and keep cables away from strong electromagnetic sources. Test the setup at the intended resolution and refresh rate before final installation and ensure both source and display devices support the selected 4K@60Hz 4:4:4 settings if required.
