6. Operating Instructions

6.1. Switching Between Inputs

The KVM switch offers multiple methods for switching between connected host devices:

• Front Panel Buttons: Press the numbered buttons (1-8) on the front panel corresponding to the desired input.
• IR Remote Control: Use the numbered buttons on the IR remote control to select the desired input. Ensure AAA batteries are installed in the remote.
• Keyboard Hotkeys: Double-tap the Scroll Lock key, then press the number (1-8) corresponding to the desired input.
• RS232/TCP/IP Commands: The switch can be controlled via RS232 serial commands or TCP/IP commands for advanced integration. Refer to the detailed protocol in the full manual for specific commands.

6.2. Auto-Scan Function

The auto-scan function allows the KVM switch to automatically cycle through connected inputs at a set interval. This is useful for monitoring multiple systems.

• Activate Auto-Scan: Use the 'P' button on the IR remote control or the dedicated auto-scan button on the front panel. The status indicator will light up.
• Adjust Scan Interval: The time interval for auto-scanning can be adjusted from 5 seconds to 60 minutes using the front panel buttons or specific remote/software commands.
• Deactivate Auto-Scan: Press the 'P' button on the IR remote control again or the auto-scan button on the front panel.

6.3. Audio Transmission

The KVM switch supports audio transmission over HDMI. If your monitor or connected display has speakers, audio from the selected host device will be played through them. An external audio output can also be used if connected to the monitor's audio out port.

6.4. EDID Technology

The KVM switch incorporates EDID (Extended Display Identification Data) technology to ensure consistent display resolution and prevent desktop icon rearrangement when switching between inputs. This feature allows the input device to maintain communication with the output device even when not actively selected, preserving native resolution settings.

7. Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the KVM switch. Do not use liquid or aerosol cleaners.
• Cable Management: Ensure cables are neatly organized and not under tension to prevent damage to ports or cables.
• Firmware Updates: Check the manufacturer's website periodically for any available firmware updates to ensure optimal performance and compatibility.

8. Troubleshooting

• No Display/Incorrect Resolution:
  • Ensure all HDMI cables are securely connected.
  • Verify that the monitor is powered on and set to the correct input source.
  • Restart the KVM switch and the connected host device.
  • If using a 4K display, ensure your host device's graphics card supports 4K@30Hz.
  • If the display resolution is incorrect, try rebooting the source device after connecting it to the switch.
• Keyboard/Mouse Not Responding:
  • Ensure the keyboard and mouse are connected to the dedicated USB ports on the KVM switch.
  • Try reconnecting the keyboard and mouse.
  • Some specialized gaming keyboards/mice may require direct connection to the computer or may not be fully compatible with KVM emulation ports. Try a standard keyboard/mouse to isolate the issue.
• Auto-Scan Not Working:
  • Verify that the auto-scan function is activated (status indicator lit).
  • Check the set time interval; it might be too long.
• No Audio:
  • Ensure HDMI cables support audio transmission.
  • Check audio settings on the host device and monitor.
• Remote Control Not Working:
  • Ensure AAA batteries are correctly installed and not depleted.
  • Verify the IR receiver cable is properly connected to the KVM switch.
  • Ensure there are no obstructions between the remote and the IR receiver.
