Connection instruction
- Connect the source device to the HDMI in port of the transmitter with an HDMI cable, and connect the HDMI out port of the receiver to the display device with another HDMI cable.
- Connect the CAT out port of the transmitter and the CAT in port of the receiver via a network cable (CAT6/CAT6A/CAT7).
- If using HDMI loop out, connect the display device to the HDMI OUT port of the transmitter.
- Plug the power supply into the device to get started.
NOTE: It is recommended to use a length range within 2-00m network cable. If the cable is too short, there may be no display output because the signal is too strong. If the cable is too long, the output may be with poor quality.
IR User Guide
- IR blaster extension cable should plug in the IR OUT port of the transmitter or receiver, IR receiver extension cable should plug in the IR IN port of the transmitter or receiver.
- The emitter of the IR blaster extension cable should be as close as possible to the IR receiving window of the source device.
- Face the receiving head of the IR receiver extension cable to the user for convenient remote control.
