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 pass back function, connect the IR blaster extension cable into the IR OUT port of the transmitter, and connect the IR receiver extension cable into the IR IN port of the receiver.
   a: The emitter of the IR blaster extension cable should be as close as possible to the IR receiving window of the source device.
   b: Point the remote control at the receiving head of the IR receiver extension cable to operate.

3. If using the KVM function, connect the keyboard/mouse to the USB port of the receiver and connect the computer to the USB port of the transmitter via the USB cable

4. Plug the power supply into the devices to get started.

5. 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.

FAQ

A: 1) Move transmitter and receiver closer. 2) Re-power the transmitter or receiver. 3) Re-pair the transmitter and receiver.

A: 1) Make sure the TX has HDMI input and that the resolution is within the specified range. 2) Try to connect the signal source directly to the display device, or change the signal source and HDMI cable and test again.

Q: Why is the display stuttering or unstable?

A: 1) Place the transmitter or receiver within the signal coverage and minimize obstructions between the transmitter and receiver. 2) Switch to a different channel to avoid interference from other wireless signals. 3) Re- power the receiver or transmitter
