How to use

Connect the HDMI source to the transmitter’s HDMI-IN and power both units with the supplied 5 V adapters. Run a Cat5e or Cat6 cable from the transmitter’s Ethernet port to the receiver’s Ethernet port; for multiple receivers use an Ethernet switch in between. Connect the receiver’s HDMI-OUT to the display. If KVM control is required, attach the USB port on the transmitter to the source PC and connect keyboard/mouse to the receiver USB ports. Use the IR controllers for remote control passthrough if needed.

Usage recommendations

For best performance use good quality Cat5e or Cat6 cable and keep cable runs within the specified 200 m maximum. Avoid running Ethernet cable alongside high-voltage power lines to minimize interference. Ensure proper ventilation for the transmitter and receiver and operate within the stated temperature and humidity ranges.
