4. Setup Guide

Follow these steps to set up your PeakDo Wireless HDMI system:

1. Identify Units: The system consists of a Transmitter (TX) and a Receiver (RX). The TX unit is typically connected to your source device, and the RX unit to your display.
2. Connect Transmitter (TX):
   • Connect the HDMI output of your source device (e.g., laptop, PC, gaming console, camera) to the HDMI input port on the PeakDo TX unit.
   • Connect a power adapter to the USB-C PD port on the TX unit. Ensure it provides sufficient power, especially if using the 100W PD fast charging feature for your source device.
3. Connect Receiver (RX):
   • Connect the HDMI output port of the PeakDo RX unit to an HDMI input port on your display device (e.g., TV, monitor, projector).
   • Connect a power adapter to the USB-C PD port on the RX unit.
4. Power On: Ensure both the TX and RX units are powered on. The devices will automatically establish a wireless connection. No Wi-Fi, app, or Bluetooth pairing is required.
5. Verify Connection: Once connected, the video and audio from your source device should appear on your display.

5. Operating Instructions

The PeakDo Wireless HDMI system is designed for plug-and-play operation. Once set up, it functions as a wireless extension of your HDMI cable.

• Automatic Connection: The TX and RX units will automatically connect when powered on and within range.
• Extended Connectivity: Utilize the additional USB-C 3.1 and USB-A 3.0 ports on both units to connect peripherals such as a mouse, keyboard, or USB storage devices. This is particularly useful for controlling presentations or navigating media from a distance.
• Applications:
  • Gaming: Experience zero-latency gaming on a large screen without the clutter of cables.
  • Streaming: Wirelessly stream 4K video content from your device to any compatible display.
  • Meetings/Presentations: Easily share content from your laptop to a projector or large monitor in conference rooms.

6. Maintenance

To ensure the longevity and optimal performance of your PeakDo Wireless HDMI system, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the exterior of the units. Avoid using liquid cleaners or abrasive materials.
• Storage: Store the devices in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
• Handling: Handle the units with care to prevent physical damage. Avoid dropping or subjecting them to strong impacts.
• Ventilation: Ensure the ventilation openings on the units are not blocked to prevent overheating.

7. Troubleshooting

If you encounter issues with your PeakDo Wireless HDMI system, refer to the following troubleshooting tips:

• No Signal on Display:
  • Ensure both TX and RX units are properly powered on and their indicator lights are active.
  • Check all HDMI cable connections between the source, TX, RX, and display.
  • Verify that the display is set to the correct HDMI input source.
  • Ensure the TX and RX units are within the specified transmission range (up to 30m/100ft) and have a clear line of sight. Obstructions can interfere with the 60GHz signal.
  • Try restarting both the source device and the display.
• Poor Video/Audio Quality or Intermittent Signal:
  • Reduce the distance between the TX and RX units.
  • Remove any obstacles (walls, furniture, etc.) that might be blocking the signal path.
  • Ensure there are no other 60GHz wireless devices operating nearby that could cause interference.
  • Check if the source device's resolution and refresh rate are supported by the system and your display.
• High Latency During Gaming/Live Streaming:
  • The system is designed for zero latency (≤2.5ms). If you experience noticeable lag, ensure the units have a clear line of sight and are not too far apart.
  • Verify that your source device and display are capable of handling the desired resolution and refresh rate without introducing their own latency.
• USB Ports Not Functioning:
  • Ensure the TX and RX units are receiving adequate power, especially if connecting power-hungry USB devices.
  • Try connecting the USB device directly to your source or display to confirm it's functional.

8. User Tips

• Optimal Placement: For best performance, place the transmitter and receiver units in a way that minimizes physical obstructions between them. A direct line of sight is ideal for maintaining a stable, low-latency connection.
• Power Supply: Always use the provided power adapters or equivalent high-quality power sources to ensure stable operation, especially when utilizing the 100W PD feature.
• Cable Quality: While the wireless connection is key, using high-quality HDMI cables for the short connections between your devices and the TX/RX units can prevent signal degradation.
• Firmware Updates: Check the manufacturer's official website periodically for any available firmware updates that might improve performance or add new features.
