Setup Instructions

Follow these steps to connect your JCHICI KVM Switch:

1. Power Off Devices: Ensure all computers and monitors are powered off before beginning the connection process.
2. Connect Monitors: Connect your two DisplayPort monitors to the KVM switch's OUTPUT-A and OUTPUT-B ports using DisplayPort cables.
3. Connect Computers (Video): For each computer (PC1, PC2, PC3, PC4), connect its two DisplayPort outputs to the corresponding INPUT-X-A and INPUT-X-B ports on the KVM switch (e.g., PC1's outputs to INPUT-1-A and INPUT-1-B). Note: Each computer must have two DisplayPort outputs and support extended display for dual monitor functionality. Adapters (HDMI/VGA/DVI/USB-C to DP) may be used if necessary.
4. Connect Computers (USB): For each computer, connect one end of the provided USB 3.0 A to B cable to the computer's USB 3.0 port and the other end to the corresponding PCX USB-B port on the KVM switch (e.g., PC1's USB to PC1 USB-B port). This enables keyboard, mouse, and USB peripheral sharing.
5. Connect Keyboard and Mouse: Connect your USB keyboard and mouse to the dedicated USB ports on the front panel of the KVM switch.
6. Connect USB Peripherals: Connect any additional USB 3.0 devices (e.g., printer, flash drive, external HDD) to the two USB 3.0 ports on the front panel.
7. Connect Wired Remote (Optional): If desired, connect the wired remote controller to the designated port on the KVM switch.
8. Power On: Connect the power adapter to the KVM switch and then plug it into a power outlet. Power on your monitors and then your computers.

Operating Instructions

Switching Between Computers

The KVM switch offers three methods for switching between connected computers:

• Front Panel Buttons: Press the corresponding PC1, PC2, PC3, or PC4 button on the front of the KVM switch to select the desired computer. LED indicators will show the active computer.
• Wired Remote Controller: Use the included wired remote to switch between computers. This is convenient for KVM placement under a desk.
• Keyboard Hotkeys: Utilize specific keyboard combinations for quick switching. The default hotkey is Scroll Lock + Scroll Lock + [1-4]. Other hotkey modes include Caps Lock + Caps Lock + [1-4] and Num Lock + Num Lock + [1-4]. To change the hotkey mode, press Ctrl + Shift + K. The KVM also supports auto-cycling through computers.

Dual Display Modes

The KVM switch supports both mirror and extended display modes, depending on your computer's settings and requirements.

• Mirror Mode: Both monitors display the same content, useful for presentations or sharing your screen.
• Extended Mode: Your desktop is extended across both monitors, providing more screen real estate for multitasking.

USB 3.0 Hub Functionality

The two USB 3.0 ports on the front panel allow you to share USB peripherals among all connected computers. When you switch to a different computer, the connected USB devices will automatically switch to that computer.

Troubleshooting

• Only One Monitor Works: If only one monitor displays content, press Win + P on your keyboard and select the desired display mode (e.g., Extend or Duplicate). Ensure your computer's graphics card supports dual DisplayPort outputs.
• Incorrect Monitor Arrangement: To adjust the left/right positioning of your monitors, go to your operating system's "Display Settings" and drag the monitor icons (Display 1 & 2) to your preferred arrangement.
• No Display/Flickering:
  • Ensure all DisplayPort cables are securely connected and are DP 1.4 compliant for 8K/4K resolutions.
  • Verify that your graphics card drivers are up to date.
  • Try restarting the KVM switch and connected computers.
• USB Devices Not Recognized:
  • Ensure the USB 3.0 A to B cables are securely connected between each computer and the KVM switch.
  • Try connecting the USB device directly to the computer to confirm it functions correctly.
  • Some high-power USB devices may require external power or a powered USB hub.
• Hotkey Switching Not Working:
  • Ensure your keyboard is connected to the dedicated keyboard USB port on the KVM switch.
  • Verify the active hotkey mode (Scroll Lock, Caps Lock, or Num Lock).
  • Some specialized keyboards may not fully support hotkey functions.
