3. Operation
Once connected, the adapter should be automatically recognized by your operating system. No additional drivers are typically required for basic functionality.

- Mirrored Display: Duplicates your primary display onto the external monitor, useful for presentations.
- Display Settings: Adjust resolution, refresh rate, and display mode through your operating system's display settings (e.g., Windows Display Settings, macOS System Preferences > Displays).
3.2 Network Connectivity
The RJ45 port provides a stable wired Ethernet connection. Your operating system should automatically detect the network connection. Verify network status in your system's network settings.
3.3 USB 3.0 Ports
The two USB 3.0 ports support data transfer speeds up to 5Gbps. Connect your USB peripherals such as external hard drives, flash drives, keyboards, and mice. These ports are backward compatible with USB 2.0 devices.
4. Maintenance
To ensure the longevity and optimal performance of your ASUS OS200 Multi-Port Adapter, follow these maintenance guidelines:

- Handling: Avoid dropping the adapter or subjecting it to strong impacts. Do not bend or twist the attached USB Type-C cable excessively.
- Connectivity: Always grasp the plug when connecting or disconnecting cables; do not pull on the cable itself.
5. Troubleshooting
If you encounter issues with your adapter, refer to the following common problems and solutions:
- No Display Output:
- Ensure the USB Type-C port on your host device supports DisplayPort Alternate Mode.
- Check that the HDMI or VGA cable is securely connected to both the adapter and the display.
- Verify that the display input source is correctly selected (e.g., HDMI 1, VGA).
- Try restarting your computer.
- Update your graphics drivers on your computer.
- No Network Connection (RJ45):
- Ensure the Ethernet cable is securely connected to both the adapter and your router/modem.
- Check the network status indicators on your router/modem.
- Verify network settings in your operating system.
- Try connecting the Ethernet cable directly to your computer (if applicable) to rule out network issues.
- USB Devices Not Recognized:
- Ensure the USB device is properly plugged into the adapter's USB 3.0 port.
- Try connecting the USB device to a different USB port on the adapter or directly to your computer.
- For high-power USB devices, ensure your host device's USB Type-C port can provide sufficient power.
- Update your computer's USB drivers.
- Adapter Feels Warm:
- It is normal for the adapter to feel warm during extended use, especially when multiple ports are active. If it becomes excessively hot, disconnect it and allow it to cool down.
