Setup Instructions

Product Prerequisites

• Ensure both computers or laptops have a DisplayPort (DP) output port and a USB-A output port.
• Ensure your monitor has a DisplayPort (DP) input port.
• Use cables that comply with the DP1.4 standard and are no longer than 6 feet (1.8 meters) in length to ensure stable video signal transmission.
• Do not use conversion cables (e.g., HDMI to DP). HDMI to DP cables and hubs are not compatible.
• This KVM switch is not compatible with MacBooks.

Connection Procedure

1. Connect PC1 to the DP port labeled "PC1 IN" on the KVM switch using a DisplayPort cable.
2. Connect PC1 to the USB 3.0 port labeled "PC1 IN" on the KVM switch using a USB-A cable.
3. Repeat the above steps for PC2, connecting it to the "PC2 IN" DP and USB 3.0 ports.
4. Connect your monitor to the "DP OUT" port of the KVM switch using a DisplayPort cable.
5. Connect the supplied 12V power adapter to the "DC12V" port on the KVM switch and plug it into a power outlet. This ensures stable operation, especially for USB devices.
6. Connect your mouse, keyboard, and other USB 3.0 peripherals (e.g., printer, webcam, U disk) to the four USB 3.0 ports on the front of the KVM switch.

Operating Instructions

Switching Between Computers

The KVM switch offers two methods for switching between the connected computers:

1. Button Switch: Press the "Select" button on the front panel of the KVM switch to toggle between PC1 and PC2. LED indicators will show which port is currently active.
2. Desktop Controller: Use the included wired desktop controller. Press the button on the controller to switch between PC1 and PC2. This allows the KVM switch unit to be hidden, keeping your desktop tidy.

Note: Keyboard shortcuts (hotkeys) for switching are not supported by this model.

USB 3.0 Connectivity

The KVM switch is equipped with four USB 3.0 ports, providing a transfer rate of up to 5Gbps. These ports are backward compatible with USB 2.0, 1.1, and 1.0 devices. You can connect various peripherals such as a mouse, keyboard, printer, webcam, and USB flash drives.

Maintenance

To ensure the longevity and optimal performance of your KVM switch, follow these general maintenance guidelines:

• Keep the device clean by wiping it with a soft, dry cloth. Avoid using liquid cleaners or aerosols.
• Ensure the device is placed in a well-ventilated area to prevent overheating.
• Avoid exposing the KVM switch to extreme temperatures, humidity, or direct sunlight.
• Do not attempt to disassemble or repair the device yourself. Refer to qualified personnel for service.

Troubleshooting

If you encounter issues with your KVM switch, please refer to the following troubleshooting steps:

1. Unable to Display:
   • Check if any conversion cables (e.g., HDMI to DP) are being used between the computer and the KVM switch. Conversion cables are not supported.
   • Verify that the DisplayPort cables used are DP1.4 compliant and no longer than 6 feet (1.8 meters).
   • Ensure all DisplayPort cables are securely connected to both the computers, the KVM switch, and the monitor.
2. Flickering Display:
   • Test with a shorter, high-quality DP1.4 cable (e.g., 3.3 feet / 1 meter) to rule out cable issues.
   • Adjust the resolution of your computer's display settings to a lower resolution to see if the flickering stops. This can help identify if the issue is related to bandwidth or cable quality at higher resolutions.
   • Ensure the 12V power adapter is connected and providing stable power to the KVM switch.
3. USB Port Does Not Work:
   • Verify that both computers are connected to the KVM switch with their respective USB-A cables (from PC to KVM's PC IN USB 3.0 port).
   • If the USB device requires significant power (e.g., external hard drive), ensure it is independently powered. The KVM switch's USB ports may not provide sufficient current for high-power devices without external power.
   • Avoid using mouse-keyboard combinations with macro functions, as these may sometimes cause compatibility issues.
   • Ensure the 12V power adapter is connected to the KVM switch, as this provides stable power for USB devices.
