Operation & Pairing

A standard wireless HDMI extender kit includes one transmitter and one receiver, which are typically paired before shipment. If you purchase additional receivers, follow the pairing instructions below:

Pairing Procedure

1. Power on the transmitter.
2. Power on the receiver until it displays the main menu.
3. Press and hold the receiver's reset button for 5 seconds until the LED flashes rapidly.
4. Wait approximately 30 seconds for the transmitter and receiver to pair automatically.

Connecting the Transmitter

Place the transmitter near your HDMI source (e.g., set-top box, Blu-ray player, Media Center PC/laptop) to send the HD video signal wirelessly to the receiver in another room.

• 1. Connect the power adapter to the connector marked "5V" and plug it into the wall socket.
• 2. Use an HDMI cable to connect the HDMI source to the port marked "HDMI IN" on the transmitter (TX).
• 3. Optional: To watch TV in the current room, connect a TV to the port marked "HDMI OUT" using an HDMI cable (not supplied).

Transmitter LED Guide:

• Red: System is booting up.
• Blue: Connected.
• Purple: No video input.

Connecting the Receiver

• 1. Connect the power adapter to the connector marked "5V" and plug it into the wall socket.
• 2. Place the receiver in the desired room (e.g., bedroom, study) for the second TV or projector.
• 3. Use an HDMI cable to connect your TV or projector to the port marked "HDMI OUT" on the receiver.

Receiver LED Guide:

• Flashing blue: Waiting for connection.
• Static blue: Connected.

Streaming Modes

The system supports both one-to-one (One TX to one RX) and one-to-many (One TX to multiple RX) streaming modes. The transmitter can support up to 4 receivers simultaneously. When a new receiver is powered on, the transmitter typically recognizes and streams video to it automatically. If automatic pairing fails, follow the "Operation & Pairing" procedure.

Connecting Infra-Red Return

The system features an "infrared return" function, enabling remote operation of the HDMI source from another room. Connect the IR cable to the transmitter's "IR" port. Attach the IR LED precisely over the HDMI source's infrared sensor. The correct position can be identified by shining a light on the front panel to locate the IR sensor window. Experiment with placement before final attachment, as the adhesive strip may cause discoloration or leave residue.

Testing the IR return function

Aim your remote control towards the IR receiver on the front of the receiver unit and send a command. The command is transferred from the receiver to the transmitter, which then forwards it to the HDMI source. The HDMI source should execute the command.

Connecting the USB Extension

The system includes a USB extension function, allowing operation of connected HDMI sources (like a Media Center PC or laptop) from another room using a mouse and/or keyboard.

• 1. To the HD transmitter: Connect your PC or laptop to the "USB" socket on the transmitter using the included Micro USB cable.
• 2. To the HD receiver: Connect your mouse and/or keyboard to the "USB" connectors on the receiver.

Testing the USB extension

Use the connected mouse/keyboard. The receiver sends the function to the transmitter, which forwards it to the PC/laptop, executing the command.

Troubleshooting

Q1. No (or poor) image and sound on TV or projector

To test, move the transmitter and receiver closer together. Ensure:

• Power is properly connected to both units.
• HDMI cables are securely connected or replaced.
• The HDMI source is ON and the correct HDMI input is selected on the TV.
• The HDMI source is set to a correct video resolution (consult source manual if needed).
• Reboot the system by disconnecting and reconnecting power adapters.
• If connection issues persist, re-pair the transmitter and receiver using the "Operation & Pairing" procedure.

Q2. No or bad connection between the HD transmitter and HD receiver

• Move the units away from nearby Wi-Fi equipment or HDMI sources that might cause interference.
• Slightly adjust the position of the transmitter and/or receiver.
• Reduce the distance between the transmitter and receiver or remove obstacles.
• Reboot the system by disconnecting and reconnecting power adapters.

Q3. I do have picture, but no (or bad) sound

The Wireless HD supports up to 2CH PCM stereo. Check the audio settings on the connected HDMI source and manually set it to 2CH PCM stereo if automatic settings fail.

Q4. The IR blaster doesn't work

• Ensure you are using the original remote control for the video source.
• Position the IR emitter probe precisely on the IR window of the source device. Refer to the source device's manual if unsure of the correct position.
• Point the remote control towards the IR receiver probe within 5 meters.
• The IR extender cable supports most IR remote signal protocols (20KHz-60KHz). Special standard or old remotes may not be supported.
