4. Setup Instructions

Follow these steps to properly install and configure your HDBaseT HDMI ARC Extender.

4.1. Basic Connection

1. Connect your HDMI source device (e.g., Blu-ray player, game console) to the HDMI IN port of the Transmitter (TX) unit using an HDMI 2.0 cable.
2. Connect your display device (e.g., TV, projector) to the HDMI OUT port of the Receiver (RX) unit using an HDMI 2.0 cable.
3. Connect the HDBaseT OUT port of the Transmitter to the HDBaseT IN port of the Receiver using a single Cat5e/Cat6/Cat7 Ethernet cable. Ensure the cable is of good quality and properly terminated.
4. Connect the 24V DC power adapter to either the Transmitter or the Receiver unit. The device supports Power over Ethernet (PoE), so only one power adapter is required.
5. Power on all connected devices.

4.2. ARC (Audio Return Channel) Setup

The EX70H2 supports ARC for returning audio from your TV to an AV receiver. ARC supports 5.1ch audio only, not Atmos. Ensure your HDMI source, TV, and AV receiver support 5.1ch audio.

1. Ensure your TV's ARC function is enabled.
2. Connect the HDMI OUT port of the Receiver (RX) to your TV's HDMI ARC port.
3. Connect the HDMI OUT port of your TV (ARC port) to your AV receiver's ARC input port.
4. On the Receiver (RX) unit, set the ARC switch to the "TV" position.
5. The extender will pass through the audio from the TV's ARC port to the AV receiver.

4.3. SPDIF Audio Return Setup (if TV does not support ARC)

If your TV does not support ARC, you can use the SPDIF optical connection for audio return.

1. Connect an optical cable from your TV's SPDIF OUT port to the SPDIF IN port on the Receiver (RX) unit.
2. On the Receiver (RX) unit, set the ARC switch to the "SPDIF" position.
3. Connect an optical cable from the SPDIF OUT port on the Transmitter (TX) unit to your AV receiver's optical input.
4. The audio from your TV will be transmitted over the Ethernet cable and output via the Transmitter's SPDIF OUT port.

4.4. IR Control Setup

The extender supports bi-directional IR control, allowing you to control the source device from the display location or the display device from the source location.

1. Connect the IR Receiver cable to the IR IN port on the unit where you want to receive IR signals (e.g., Receiver unit near the TV to control the source).
2. Position the IR Receiver eye in a location where it can receive signals from your remote control.
3. Connect the IR Emitter cable to the IR OUT port on the other unit (e.g., Transmitter unit near the source).
4. Place the IR Emitter head directly over the IR sensor of the device you wish to control.

4.5. CEC Control

The EX70H2 supports CEC (Consumer Electronics Control). Ensure your TV and connected devices support CEC and that the function is enabled in their settings. Connect the HDMI cables to CEC/ARC compatible HDMI ports on your TV.

4.6. Scaler Function

The Transmitter unit features a SCALER switch. When set to "ON", it will down-scale a 4K input signal to 1080P output. This is useful if your display device only supports 1080P. If your display supports 4K, ensure the SCALER switch is set to "OFF" for optimal 4K picture quality. For 4K content, power on the 4K TV first, then connect the HDBaseT Extender TX and RX units.

5. Operating Instructions

Once all connections are made and devices are powered on, the extender will automatically detect the HDMI signal and transmit it. The LED indicators on both units will provide status information:

• POWER LED: Illuminates when power is supplied.
• WORK LED: Illuminates when the unit is operating correctly.
• LINK LED: Illuminates when a stable HDBaseT link is established between TX and RX.
• STATUS/SIGNAL LED: Illuminates when an HDMI signal is detected and being transmitted/received.

Ensure all LEDs indicate proper operation for optimal performance.

7. Troubleshooting

If you encounter issues, refer to the following common problems and solutions:

• No Video/Audio:
  • Ensure all HDMI and Ethernet cables are securely connected.
  • Verify that the power adapter is connected and the POWER LED is illuminated on at least one unit.
  • Check if the LINK and STATUS/SIGNAL LEDs are illuminated on both TX and RX units.
  • Test with shorter, certified HDMI cables directly connected to source and display to confirm they function independently.
  • Try a different Cat5e/6/7 cable.
  • If using 4K, ensure the SCALER switch on the TX unit is set to "OFF".
  • Power cycle all devices (source, extender, display).
• ARC/SPDIF Audio Not Working:
  • Ensure your TV's ARC function is enabled in its settings.
  • Verify the ARC switch on the RX unit is set to the correct mode ("TV" for HDMI ARC, "SPDIF" for optical).
  • Confirm that your AV receiver is set to the correct input for ARC or optical audio.
  • Ensure all audio cables (HDMI ARC, optical) are correctly connected.
  • Remember ARC supports 5.1ch audio only, not Atmos.
• IR Control Not Working:
  • Ensure the IR Emitter head is placed directly over the IR sensor of the device to be controlled.
  • Verify the IR Receiver eye is positioned to receive signals from your remote.
  • Check that the IR cables are securely plugged into the correct IR IN/OUT ports.
• Intermittent Signal/Poor Picture Quality:
  • Use high-quality Cat6 or Cat7 cable for longer distances.
  • Avoid running the Ethernet cable near strong electromagnetic interference sources.
  • Ensure the Ethernet cable is not excessively bent or damaged.
  • If transmitting 4K, ensure the SCALER switch is OFF.
