how to install KanexPro Video Extender Transmitter/Receiver

Begin by planning a clean, fiber-friendly route that minimizes bending and avoids sources of EMI. Verify that your fiber infrastructure is prepared for the chosen fiber type (two single‑mode fibers or two OM3/OM4 multimode fibers) and that the running lengths align with the 300 m (984 ft) maximum for reliable signal integrity. Position the transmitter and receiver units in their intended locations, ensuring access to HDMI sources and displays as well as space for cable management and ventilation.

Step 1: Connect the HDMI source to the transmitter’s HDMI input using a high‑quality HDMI cable. Ensure the source is powered on and configured for the desired resolution and HDR settings.

Step 2: Connect the HDMI display to the receiver’s HDMI output with another HDMI cable. Verify that the display is set to the correct input and that HDR and color settings are compatible with your source content.

Step 3: Run two fiber cables between the transmitter and receiver. Depending on your installation, use either two single‑mode fibers or two OM3/OM4 multimode fibers. Ensure connectors are clean and fully seated to prevent signal loss.

Step 4: Provide power to both units with the appropriate power adapters. Confirm that all power indicators are active and that there are no fault indicators on the housings.

Step 5: Power up the system and perform a basic handshake test. Play back content at the highest supported resolution (4K@60Hz) to confirm 4:4:4 chroma and HDR are preserved across the link. If you encounter any HDCP handshake issues, verify cable integrity, fiber terminations, and source/display HDCP settings.

Step 6: If your installation includes multiple displays or a video wall, configure the EDID and output settings on the source to ensure consistent color, frame rate, and aspect ratio across all displays. In controlled environments, you may need to adjust color management and reference levels to match display capabilities.

Step 7: Perform post‑installation testing for latency, lip‑sync, and picture quality under real‑world conditions. Validate that signal integrity remains stable during prolonged playback and that fiber routes remain free of stress or movement that could degrade the connection.

Step 8: Create installation documentation for future maintenance, including fiber path diagrams, connector types, and any site‑specific configuration notes. This ensures quick troubleshooting and scalable upgrades as your AV network evolves.
