One-to-One Connection

Connection Instructions

1. 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.
2. If using the IR passback function, connect the IR blaster extension cable to the IR OUT port of the transmitter, and connect the IR receiver extension cable to the IR IN port of the receiver.
   • The emitter of the IR blaster extension cable should be as close as possible to the IR receiving window of the source device.
   • Point the remote control at the receiving head of the IR receiver extension cable to operate.
3. Plug the power supply into the devices to get started.
4. In the case of multiple sets being used at the same time in the same area. In order to prevent mutual interference, switch each set of transmitters and receivers to a different channel after they have been manually paired with the SSID.

SSID Pairing

1. Enter the SSID pairing mode by holding the transmitter and receiver’s channel switch buttons for five seconds. Both WiFi connection indicators will flash quickly in yellow.
2. When the SSID pairing is successful, the WiFi indicators on the transmitter and receiver will change from quick flashing to slow flashing or steady on.
