- IR Remote Control: Use the included IR remote to select input ports. Ensure AAA batteries are installed in the remote.
- Mouse Wheel Switching: Move the mouse cursor to the edge of the screen and scroll the mouse wheel to switch inputs. (Specific instructions may vary, refer to the full manual for details).
- RS232 Control: Connect to the RS232 port and use serial commands from a computer for control.
- LAN Port (IP Control): Connect the KVM to your network via the LAN port and use IP commands for remote control.
4.2 Auto Scan Mode

- Cable Management: Keep cables organized and free from kinks or excessive bends to prevent damage and ensure reliable connections.
- Power Supply: Use only the provided power adapter. Disconnect the power supply during electrical storms or when the unit is unused for extended periods.
- Environmental Conditions: Operate the KVM switch within its specified temperature and humidity ranges. Avoid extreme conditions.
6. Troubleshooting
If you encounter issues with your TESmart 8X1 HDMI KVM Switch, refer to the following common troubleshooting steps:
6.1 No Display or Flickering Screen
- Check Cables: Ensure all HDMI and KVM cables are securely connected to both the KVM switch and the computers/monitor. Try replacing cables if issues persist.
- Power Cycle: Power off the KVM switch and all connected computers. Wait a few seconds, then power on the KVM switch first, followed by the computers.
- Resolution Compatibility: Verify that your monitor and graphics cards support the output resolution (up to 4K@30Hz).
- EDID Emulation: The built-in EDID emulator should prevent most display issues. If problems occur, ensure the KVM is powered on before the computers.
6.2 Keyboard or Mouse Not Responding
- Check Connections: Ensure the keyboard and mouse are connected to the dedicated K/M USB ports on the front panel.
- Try Different Ports: If using a wireless keyboard/mouse with a USB receiver, try connecting the receiver to one of the general USB 2.0 hub ports instead of the dedicated K/M ports, especially if experiencing issues with specific features or software (e.g., Logitech Options+).
- Power Cycle: Disconnect and reconnect the keyboard and mouse, or power cycle the KVM switch.
- Hot Plug & Auto Detect: The KVM supports hot-plugging. Try unplugging and re-plugging the keyboard/mouse USB connector.
6.3 Switching Issues
- Hotkey Sequence: Ensure the correct hotkey sequence (Scroll Lock + Scroll Lock + Port Number) is being used.
- IR Remote: Check if the IR remote has fresh AAA batteries and that the IR receiver cable is properly connected and positioned.
- Front Panel: Verify that the front panel buttons are responsive.
6.4 Other Considerations
- Bright LED: The blue numeric LED indicator on the front panel is bright and cannot be dimmed. Users may choose to cover it with opaque material if desired.
- No Rubber Feet: The unit does not include rubber feet. Users may add their own for stability on a desktop.
- Short Power Cable: If the included power cable is too short for your setup, an extension cord may be required.
