5. Setup Instructions
Follow these steps to set up your PWAY HT129H extender:
- Connect HDMI Source to Transmitter: Use an HDMI cable to connect your HDMI source device (e.g., computer, media player) to the HDMI IN port on the Transmitter (TX) unit.
- Connect Local Display (Optional): If you wish to have a local display near your source, connect an HDMI cable from the HDMI OUT (Loop) port on the TX unit to your local monitor.
- Connect USB to Source: Connect the provided USB cable from the USB port on the TX unit to a USB port on your HDMI source device. This enables KVM functionality.
- Connect Remote Display to Receiver: Use an HDMI cable to connect your remote HDMI display (e.g., TV, monitor) to the HDMI OUT port on the Receiver (RX) unit.
- Connect Keyboard and Mouse: Connect your USB keyboard and mouse to the USB (K/M) ports on the RX unit.
- Connect Cat Cable: Connect a single Cat5e, Cat6, or Cat7 Ethernet cable between the RJ45 (LAN) port on the TX unit and the RJ45 (LAN) port on the RX unit. Ensure the cable is properly terminated (standard IEEE-T568B recommended) and does not exceed 328 feet (100 meters).
- Connect IR Cables (Optional):
- Connect the IR Blaster cable to the IR OUT port on the TX unit and place the IR emitter near the IR sensor of your source device.
- Connect the IR Receiver cable to the IR IN port on the RX unit and place the IR receiver in a location where it can receive signals from your remote control.
- Apply Power: Connect the two provided 12V DC power adapters to the DC 12V input ports on both the TX and RX units, then plug them into power outlets. The Power LED indicators on both units should illuminate.
- Verify Connection: Once powered, the Link LED on both units should illuminate, indicating a successful connection over the Cat cable. The Status LED will indicate data transmission.
6. Operating Instructions
After successful setup, the PWAY HT129H extender operates automatically.
6.1 Video and Audio Transmission
The extender will transmit the HDMI video and audio signal from your source device to the remote display. If a local display is connected to the TX unit's loop-out, it will also display the same content.

6.3 IR Remote Control
If the IR cables are connected, you can use your source device's original remote control at the remote display location. Point the remote at the IR Receiver connected to the RX unit, and the signal will be transmitted back to the IR Blaster at the TX unit to control your source device.

7. Maintenance
To ensure optimal performance and longevity of your PWAY HT129H extender, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the units. Do not use liquid or aerosol cleaners.
- Ventilation: Ensure the units are placed in a well-ventilated area to prevent overheating. Do not block ventilation openings.
- Power: Use only the provided power adapters. Disconnect power during electrical storms or when unused for long periods.
- Environment: Avoid exposing the units to extreme temperatures, humidity, or direct sunlight.
8. Troubleshooting
If you encounter issues with your PWAY HT129H extender, refer to the following troubleshooting steps:
- No Video/Audio Output:
- Check all HDMI cable connections between source, TX, RX, and displays.
- Ensure the Cat5e/6/7 cable is securely connected to both TX and RX units and is not damaged. Verify the Link LED is illuminated.
- Confirm both TX and RX units are powered on and their Power LEDs are illuminated.
- Try a different HDMI source or display to rule out compatibility issues.
- Ensure the resolution of your source device is supported (up to 4K@60Hz).
- KVM (Keyboard/Mouse) Not Working:
- Verify the USB cable is connected from the TX unit to the source device.
- Ensure the keyboard and mouse are connected to the correct USB ports on the RX unit.
- Test the keyboard and mouse directly with the source device to confirm they are functional.
- Note: This extender may be finicky with certain USB devices. USB hubs or wireless gamepad adapters may not be supported. It is primarily designed for standard USB keyboards and mice.
- IR Remote Control Not Working:
- Check that the IR Blaster and IR Receiver cables are correctly connected to the TX and RX units, respectively.
- Ensure the IR Blaster's emitter head is directly over the IR sensor of your source device.
- Confirm the IR Receiver is positioned to receive signals from your remote control.
- Verify the remote control has working batteries.
- Intermittent Signal/Flickering:
- Check the quality and length of your Cat5e/6/7 cable. A higher quality (e.g., Cat6 or Cat7) cable is recommended for longer distances and higher resolutions.
- Ensure the cable is not run near sources of strong electromagnetic interference.
- Note: This extender does not support HDR or Variable Refresh Rate (VRR/G-Sync). Attempting to use these features may result in black screens or flickering.
