CMSTEDCD USB C Docking Station with KVM Switch

1. Introduction

The CMSTEDCD USB C Docking Station with KVM Switch, Model JHS-US-SW524, is designed to enhance your workspace efficiency. This device allows you to control two computers and two monitors using a single set of keyboard and mouse, facilitating seamless switching between work and personal computers. It functions as a 12-in-1 multifunction docking station, providing a variety of ports including Gigabit Ethernet, USB 3.2, USB-C, and SD/microSD card slots for convenient data transfer and peripheral connectivity.

This docking station supports resolutions up to 4K@60Hz, offering both dual display docking mode (two monitors output different images) and dual display mirroring mode (two monitors output the same image). EDID emulation helps maintain display settings and prevents icon rearrangement when switching between systems.

3. Operating Instructions

3.1 Switching Between Computers

The docking station offers two methods for switching between connected computers:

• Manual Button Switch: Press the 'Select' button located on the front panel of the docking station to switch between PC1 and PC2.
• Computer Controller: Use the included computer controller (wired remote) to switch between computers. This allows you to place the docking station out of sight for a cleaner desk setup.

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

3.2 Display Modes

The docking station supports various display configurations:

• Dual Display Docking Mode: Each monitor displays a different image, extending your desktop across two screens.
• Dual Display Mirroring Mode: Both monitors display the same image.

Important Considerations:

• macOS only supports mirror mode for external displays through this device.
• EDID emulation helps prevent resolution and icon rearrangement when switching, simplifying your workflow.

3.3 Network and USB Data Transfer

• The 1G Gigabit Ethernet port provides high-speed wired network access.
• Note: The network connection follows the current channel switching and cannot be used by two computers simultaneously.
• The USB-C port on the front panel is for data transfer only and does not support Power Delivery (PD) charging or video streaming.

4. Maintenance

To ensure the longevity and optimal performance of your docking station, follow these maintenance guidelines:

• Keep the device in a clean, dry environment, away from direct sunlight, excessive heat, and moisture.
• Avoid blocking the ventilation slots on the sides of the device to prevent overheating.
• Clean the exterior with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
• Handle cables and connectors gently to prevent damage.

5. Troubleshooting

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

• No Display or Incorrect Resolution:
  • Ensure all HDMI and USB-C cables are securely connected.
  • Verify that your computer's USB-C port supports video transmission.
  • Confirm that your monitors and cables support the desired resolution (e.g., 4K@60Hz).
  • Check your computer's display settings to ensure the external monitors are detected and configured correctly (extended or mirrored).
  • If using macOS, remember it only supports mirror mode for external displays through this device.
  • Try power cycling the docking station and connected devices.
• Peripherals (Keyboard/Mouse) Not Responding:
  • Ensure the USB cables for your peripherals are firmly connected to the docking station.
  • Confirm the docking station is switched to the correct computer (PC1 or PC2).
  • Try connecting the peripherals directly to the computer to rule out device issues.
• No Network Connection:
  • Verify the Ethernet cable is securely connected to both the docking station and your router/modem.
  • Ensure the docking station is switched to the computer you intend to use the network with, as the network cannot be shared simultaneously.
  • Check your computer's network settings.
• USB-C Front Port Not Charging or Displaying Video:
  • The USB-C port on the front panel is designed for data transfer only. It does not support Power Delivery (PD) charging or video output.
