Follow these steps to correctly set up your CMSTEDCD SW222-0910 KVM Switch:

1. Power Off Devices: Ensure both computers and monitors are powered off before beginning the connection process.
2. Connect Monitors to KVM: Connect your primary monitor to the KVM's HDMI output (OUT A) and your secondary monitor to the KVM's DisplayPort output (OUT B).
3. Connect Computers to KVM (PC1):
   • Connect a USB 3.0 A-A cable from your first computer's USB-A port to the KVM's PC1 USB 3.0 input.
   • Connect an HDMI cable from your first computer's HDMI output to the KVM's PC1 HDMI input.
   • Connect a DisplayPort cable from your first computer's DisplayPort output to the KVM's PC1 DisplayPort input.
4. Connect Computers to KVM (PC2): Repeat step 3 for your second computer, connecting its USB 3.0, HDMI, and DisplayPort outputs to the corresponding PC2 inputs on the KVM.
5. Connect Peripherals: Connect your USB keyboard, mouse, printer, or other USB 3.0 devices to the four USB 3.0 ports on the front of the KVM switch.
6. Connect Wired Control: Plug the wired desktop control button into the designated port on the KVM switch.
7. Connect Power: Plug the 12V DC power adapter into the KVM switch and then into a power outlet.
8. Power On: Power on your monitors and then your computers.

Important Notes:

• Both computers and monitors must have native HDMI and DisplayPort outputs/inputs.
• The use of HDMI to DisplayPort, DisplayPort to HDMI, or any other conversion cables (e.g., HDMI to DVI/VGA) is not supported and may prevent proper functionality.
• Ensure you use high-quality HDMI 2.1 and DisplayPort 1.4 cables (not included) for optimal performance, especially for 4K@120Hz or 8K@60Hz resolutions.

7. Maintenance

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

• Keep the device in a cool, dry place, away from direct sunlight and excessive heat.
• Avoid exposing the KVM switch to liquids or moisture.
• Clean the exterior with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
• Ensure proper ventilation around the device to prevent overheating.

8. Troubleshooting

If you encounter issues with your KVM switch, refer to the following common problems and solutions:

8.1 USB Not Working

• Check USB 3.0 Cable: Confirm that the USB 3.0 cable is properly connected between your computer and the KVM switch.
• Verify Computer USB Port: Ensure the USB port on your computer is functioning correctly. Test it with another device.
• Update USB Drivers: Install the latest USB drivers for your computer's operating system.
• External Power: Ensure the 12V power adapter is connected to the KVM switch. The current provided by a PC host alone may be insufficient for some USB devices, especially hard drives.

8.2 Display Has No Image

• Match Video Ports: Confirm that the KVM switch's video ports (HDMI and DisplayPort) match the corresponding ports on your monitors and computers.
• Correct Input Connection: Ensure that PC1's video cables are connected to the KVM's PC1 inputs, and PC2's video cables are connected to PC2 inputs. Also, verify that the KVM's OUT A connects to your primary monitor and OUT B to your secondary monitor.
• Cable Quality: Use high-quality HDMI 2.1 and DisplayPort 1.4 cables, preferably 3.3ft or shorter for optimal signal integrity.
• Avoid Conversion Cables: Do not use HDMI to DisplayPort, DisplayPort to HDMI, or any other video conversion cables. Direct connections are required.
• Active Adapters: If an adapter is absolutely necessary (e.g., for a specific legacy setup), ensure it is an active adapter, though direct connections are always recommended.
• Restart Devices: Try restarting the KVM switch, monitors, and computers in sequence.
