How to use

Insert the module into a compatible keystone opening on a wall plate or patch panel until it snaps into place. Connect an HDMI cable from the source device to the rear of the module and a second HDMI cable from the front of the module to the display or receiver. Ensure cables are fully seated in the connector to maintain a stable signal path; avoid sharp bends near the connection to reduce stress on the cable and module.

Recommendations

For reliable performance, use high-quality HDMI cables rated for the required resolution and refresh rate. When installing in structured cabling systems, verify that the wall plate and mounting frame provide adequate support and clearance for the flat module. Periodically inspect connectors for dust or debris and clean with compressed air if necessary.
