EDID Management
The matrix switch supports EDID (Extended Display Identification Data) management to ensure optimal compatibility between sources and displays. This feature allows you to select the best EDID settings for your connected devices, preventing resolution or audio issues.
- EDID settings can typically be configured via the Web GUI or RS-232 commands.
- Options may include copying EDID from a specific output, using a default EDID, or custom EDID settings.
Scene Management
The device includes a built-in pre-plan management system that allows you to save and recall up to 32 different input/output configurations (scenes). This is useful for quickly switching between complex setups.
- Saving a Scene: Configure your desired input-to-output routing, then use the control interface (Web GUI, RS-232, or local buttons) to save this configuration as a scene.
- Recalling a Scene: Select the desired scene number from the control interface to instantly apply the saved configuration.
Video Switching Modes
The matrix switch supports various display configurations:
- Independent Switching: Each display can show a different input source.
- Shared Input: Multiple displays can share the same input source.
- Partial Sharing: Some displays show independent sources, while others share a common source.
