5. Setup Instructions
Follow these steps to set up your ZHIXIN Wireless HDMI Extender:
- Identify Transmitter (TX) and Receiver (RX): The transmitter is labeled 'TX Source' and the receiver is labeled 'RX Display'.
- Connect Transmitter (TX) to Source Device: Plug the HDMI end of the transmitter into the HDMI output port of your source device (e.g., PC, laptop, TV box, camera). If your source device uses USB-C, Mini HDMI, or Micro HDMI, use the appropriate adapter (Max 4K support for adapters).
- Connect Receiver (RX) to Display Device: Plug the HDMI end of the receiver into the HDMI input port of your display device (e.g., projector, monitor, TV, portable display).
- Power On Both Units: Connect the provided USB to USB-C power cables to both the transmitter and receiver, and then plug them into a 5V power source (e.g., USB port on your device, USB wall adapter). Ensure both units receive power.
- Automatic Connection: The transmitter and receiver should automatically connect. Observe the indicator lights for connection status.
6. Operating Instructions
6.1. Indicator Lights
The transmitter and receiver units feature LED indicators to provide status information:
- 1. Pairing Button: Used to initiate or reset the pairing process.
- 2. Power Indicator: Indicates if the unit is powered on.
- 3. Pairing Indicator Light:
- Slow flash: Not connected
- Fast flash: Pairing in progress
- Always on: Connected
- 4. HDMI Status Indicator:
- Always on: HDMI connected
- Always off: HDMI not connected
- 5. Signal Strength Indicator: Displays the strength of the wireless signal. (No specific instruction for 'Always off' or 'No signal' provided for this indicator in the image text, but it is present on the device.)
6.2. Pairing
The units are designed to pair automatically upon power-up. If they do not connect, or if you need to re-pair them:
- Ensure both the transmitter and receiver are powered on.
- Press the Pairing Button (1) on both the transmitter and receiver.
- Observe the Pairing Indicator Light (3). It should fast flash during pairing and then become solid when connected.
6.3. Display Modes
The system supports two primary display modes:
- Copy Mode (Mirroring): The display device shows the exact same content as your source device's screen.
- Extended Mode: The display device acts as an extension of your source device's screen, allowing you to display different content or extend your desktop workspace.
7. Troubleshooting
- No Signal/Poor Signal:
- Ensure both TX and RX units are powered on and their indicator lights show a connected status.
- Check that the HDMI cables (if used with adapters) are securely connected to both the source and display devices.
- Verify that the display device is set to the correct HDMI input.
- Environmental Factors: Transmission distance can be affected by the environment. Walls, brick, or glass will shorten the signal range or cause significant signal loss. Try to minimize obstructions between the transmitter and receiver.
- Try re-pairing the units as described in Section 6.2.
- Image/Audio Issues (Stuttering, Flickering):
- This may indicate a weak signal. Reduce the distance between the TX and RX units or remove obstructions.
- Ensure both units are receiving stable 5V power.
- Units Not Powering On:
- Check the USB to USB-C power cables and ensure they are properly connected to a working 5V power source.
- Try a different USB power adapter or USB port.
8. User Tips
- For optimal performance and to maintain the 60-meter range, ensure a clear line of sight between the transmitter and receiver.
- The LED digital display is a useful tool for quickly checking the connection status and signal strength, which can help in diagnosing issues.
- When using the extender in different rooms or through walls, expect a reduction in the effective transmission range.
- Always ensure both the transmitter and receiver are adequately powered to prevent performance issues.
9. Maintenance
To ensure the longevity and optimal performance of your ZHIXIN Wireless HDMI Extender:
- Keep the devices clean by wiping them with a soft, dry cloth. Avoid using liquid cleaners or solvents.
- Store the units in a cool, dry place away from direct sunlight and extreme temperatures.
