Operation Instructions:

1. After the device is powered on, the default port is a USB Type-C™ notebook computer connection port, and the red indicator light on the panel is lit.
2. Hotkey operation is performed once, and the port is changed once, thus circulating.
3. If the connected peripherals are printers, mobile hard disks… etc., please do not switch ports during data transmission, otherwise, data transmission errors may occur.

Power supply for Device
There are three power supply modes for this KVM switch product:

1. The user can choose an adapter power supply conforming to the USB Type-C™ PD standard to connect the device and provide the power needed for operation.
2. Users can choose the USB interface of the PC and use the USB of the PC to provide the power required by the device.
3. If the USB USB TYPE-C™ interface of the user’s notebook computer can provide a power output function, it can also provide a power supply for the device through USB Type-C™.

Note: The external TYPEC interface of this product can provide power output for the downlink connection device. The application of this model needs to ensure that the device has a power adapter matching the corresponding power supply. The TYPE-C power adapter supports a power supply capacity of up to 100W W. For example, users only need simple applications and can provide power through the USB of a PC or TYPEC of a notebook computer. Users use the application mode of power mismatch, which may cause the device to work abnormally or not. Please check whether the application of the device needs to add additional power adapters before using.
