Installation Procedures
Connection Diagrams
One to one connection
Diagram illustrating a one-to-one connection: A PC is connected via HDMI IN to the Transmitter (TX). The Transmitter has a USB OUT connected to a USB IN on the Receiver (RX). The Receiver has an HDMI OUT connected to an HDMI Display. The Receiver also has a USB IN connected to a Keyboard & Mouse.
Up to one to four connection
Diagram illustrating an up to one-to-four connection: A PC is connected via HDMI IN to the Transmitter (TX). The Transmitter has a USB OUT. Four Receivers (RX1, RX2, RX3, RX4) are shown, each connected to an HDMI Display via HDMI OUT. Each Receiver has a USB IN connected to peripherals: RX1 to Keyboard & Mouse, RX2 to Touch Screen, RX3 to Keyboard & Mouse, RX4 to Keyboard & Mouse.
Connection Instructions
- 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.
- If using the IR passback 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.
- 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.
- Plug the power supply into the devices to get started.
- 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
- 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.
- Once all receivers have been successfully paired (the RX WiFi indicators has changed from a quick flash to a slow flash), short press the transmitter channel switch button to end the pairing, and the TX/RX WiFi indicators will flash slowly or steady on.
