Installation and Wiring

Installation

Warnings:

• Before wiring, disconnect the power from the device.
• During wiring, connect and disconnect the cables gently.

Steps to install the device:

1. Attach the installation bracket to the enclosure using the screws provided in the package separately.
2. The bracket is attached to the enclosure as shown.
3. Repeat the steps from 1 to 2 for the other side of the unit.
4. Attach the brackets to the surface you want to hold the unit against using the screws (provided by others).
5. Repeat the steps from 1 to 4 to install the receiver.

Wiring

Warnings:

1. Before wiring, disconnect the power from all devices.
2. During wiring, connect and disconnect the cables gently.

Note: Ensure the connected display support eARC/ARC function and its CEC function should be set to enable.
The extender supports two channels to output eARC/ARC audio from the connected display.

1. Set the DIP switch of transmitter to eARC/ARC or S/PDIF channel (See “DIP Switch Settings” section).
2. Connect the receiver’s HDMI IN port to an AV Receiver’s eARC/ARC HDMI output port. Or connect the receiver’s S/PDIF OUT port to an AV Receiver’s Toslink input port.
3. Connect the transmitter’s HDMI OUT port to a display’s eARC/ARC input port. Or connect the transmitter’s S/PDIF IN port to a display’s Toslink output port.
4. Connect UTP OUT port of the transmitter to UTP IN port of the receiver.
5. Using the provided Micro USB to USB Type-A cables to connect the transmitter and receiver to 5V power sources.
6. Power on all attached devices. The return audio signal from HDMI OUT port will be transmitted to HDMI IN port, or the return audio signal from S/PDIF IN port will be transmitted to S/PDIF OUT port (according to the selection in step 1).

For additional wiring:

• Bi-directional IR pass-through: Connect the provided IR receiver to IR IN port of the transmitter/receiver, and connect the provided IR emitter to IR OUT port of the receiver/transmitter. You can control the display at receiver side or control the AV receiver at transmitter side.
• Bi-directional RS232 pass-through: Connect RS232 enabled devices such as PC to RS232 ports of the transmitter and receiver. (See “RS232 Pass-Through” section)
