1. Power Off Devices: Ensure all HDMI source devices and display devices are powered off before making any connections.
2. Connect HDMI Source to Transmitter: Use a high-quality HDMI cable to connect your HDMI source (e.g., PC, laptop, TV Box) to the HDMI Input port on the Transmitter unit.
3. Connect Local Display (Optional): If you wish to monitor the source signal locally, connect an HDMI display to the Loopout HDMI Output port on the Transmitter unit using an HDMI cable.
4. Connect Receivers to Displays: For each of the four remote displays, connect an HDMI cable from the HDMI Output port on a Receiver unit to the HDMI input of your display device (e.g., TV, projector).
5. Connect Transmitter to Receivers via CAT6: Use high-quality CAT6 network cables (up to 100 meters/328 feet) to connect the CAT6 Outputs (1-4) on the Transmitter unit to the RJ45 Input (CAT6) on each of the four Receiver units.
6. Power On Transmitter: Connect the 12V power adapter to the DC 12V Power Input on the Transmitter unit and plug it into a power outlet. The PWR LED should illuminate.
7. Power On Receivers: Connect the 5V power adapters to the DC 5V Power Input on each Receiver unit and plug them into power outlets.
8. Power On Devices: Power on your HDMI source device and all connected display devices.
9. EDID Copy (If Needed): If you experience display compatibility issues, you may need to use the EDID Copy function. Connect the desired display directly to the transmitter's HDMI input (or loopout) and press the EDID Button. Refer to Section 5.2 for detailed EDID instructions.

5. Operating Instructions

Once the system is set up, operation is straightforward. The extender splitter works automatically to transmit the HDMI signal.

5.1 Indicator Lights

• Transmitter PWR LED: Solid green indicates the transmitter is powered on.
• Transmitter STA LED: Solid green indicates a stable HDMI input signal.
• Transmitter RUN LEDs (1-4): Solid green indicates an active and stable CAT6 connection to the corresponding receiver.
• Receiver STA LED: Solid green indicates a stable CAT6 signal received from the transmitter.

5.2 EDID Copy Function

The EDID (Extended Display Identification Data) copy function helps ensure optimal compatibility between your HDMI source and display devices, especially when using multiple displays with varying capabilities.

1. Connect Source and Target Display: Ensure your HDMI source is connected to the Transmitter's HDMI Input. Connect the display whose EDID you want to copy to the Transmitter's Loopout HDMI Output.
2. Initiate EDID Copy: With both devices powered on and connected, press and hold the EDID Button on the Transmitter for approximately 3-5 seconds until the STA LED flashes. This indicates the EDID has been successfully copied.
3. Verify: The transmitter will now use the copied EDID information for all connected displays, which can resolve resolution or audio compatibility issues.
