5. Operating Instructions

5.1 EDID Management

The EDID (Extended Display Identification Data) switches on the transmitter unit allow you to manage the communication between your source and displays, ensuring optimal compatibility and picture quality. Incorrect EDID settings can lead to display issues or no signal. Refer to the EDID table in your user manual to select the appropriate settings for your setup.

5.2 EQ (Equalization) Adjustment

The EQ switches on each receiver unit are used to compensate for signal degradation over long CAT cable runs. Adjust these switches based on the actual length of the CAT cable connecting the receiver to the transmitter. Proper EQ adjustment is crucial for maintaining signal integrity and preventing flickering or signal loss. Consult the EQ settings table in your user manual for guidance.

5.3 IR Remote Control

The IR pass-back feature allows you to control your HDMI source device from any of the remote display locations. Simply point your source device's remote control at the IR Receiver connected to the display's receiver unit. The signal will be transmitted back to the IR Blaster connected to the transmitter unit, which then relays the command to your source device.
