5.3 Auto Scan Mode

In Auto Scan Mode, the KVM switch cycles through all connected active inputs at a user-defined interval (e.g., 5 seconds to 1 hour). This is useful for monitoring multiple systems.

6. Maintenance

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

• Cleaning: Use a soft, dry cloth to clean the exterior of the device. Avoid using liquid cleaners or solvents.
• Ventilation: Ensure the KVM switch has adequate ventilation. Do not block any ventilation openings.
• Environment: Operate the device within the specified temperature range (up to 40°C). Avoid extreme temperatures, humidity, and direct sunlight.
• Cable Management: Keep cables organized and free from kinks or excessive tension to prevent damage to connectors and ports.
• Firmware Updates: Check the manufacturer's website periodically for any available firmware updates that may improve performance or add features.

7. Troubleshooting

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

• No Display/Signal:
  • Ensure all HDMI and USB cables are securely connected to both the KVM switch and the computers/monitor.
  • Verify the KVM switch is powered on and the correct input is selected.
  • Try connecting the computer directly to the monitor to confirm the computer's video output is functional.
  • Check if the monitor is set to the correct input source.
• Keyboard/Mouse Not Responding:
  • Ensure the keyboard and mouse are connected to the dedicated K/M USB ports on the KVM switch.
  • Try connecting the keyboard and mouse directly to the computer to verify functionality.
  • Some specialized gaming or multimedia keyboards/mice may require pass-through mode. Refer to the full manual for enabling this feature.
• Slow Switching Time:
  • Switching times can vary depending on the connected devices and their display handshake processes. High-resolution or high-refresh-rate devices (e.g., PS5 at 4K 120Hz HDR) may experience longer switching delays (up to 5 minutes in some cases).
  • For other devices, typical switching time is 5-10 seconds.
• Display Issues with High-Performance Devices (e.g., PS5):
  • Devices requiring 4K 120Hz HDR VRR may be particularly sensitive to HDMI signal integrity.
  • Ensure high-quality HDMI 2.1 certified cables are used.
  • Consider simplifying the setup by connecting the KVM switch directly to the display, rather than through an A/V receiver, if experiencing signal drops or resolution degradation.
  • If green lines or signal loss occur, try adjusting display settings on the source device to a lower resolution or refresh rate as a test.
• Audio Issues (e.g., Dolby Atmos):
  • This KVM switch may not support certain advanced audio formats like Dolby Atmos. Verify audio compatibility with your specific setup.
• Control Software Issues:
  • If experiencing difficulties with official control software for advanced settings (e.g., disabling the beep sound), check the TESmart website for updated software or drivers.
  • Some users have reported success with third-party applications for controlling TESmart KVM switches; however, use such software at your own discretion.
